No matter what, you must pick 'IPMI top-level message handler' to use
IPMI. What you do beyond that depends on your needs and hardware.
The message handler does not provide any user-level interfaces.
Kernel code (like the watchdog) can still use it. If you need access
from userland, you need to select 'Device interface for IPMI' if you
-want access through a device driver. Another interface is also

IPMI defines a standard watchdog timer. You can enable this with the

'Disable watchdog shutdown on close'.
+IPMI systems can often be powered off using IPMI commands. Select
+'IPMI Poweroff' to do this. The driver will auto-detect if the system

Basic Design
------------
The Linux IPMI driver is designed to be very modular and flexible, you
only need to take the pieces you need and you can use it in many
different ways. Because of that, it's broken into many chunks of
-code. These chunks are:
+code. These chunks (by module name) are:
ipmi_msghandler - This is the central piece of software for the IPMI
system. It handles all messages, message timing, and responses. The
driver, each open file for this device ties in to the message handler
as an IPMI user.
-ipmi_si - A driver for various system interfaces. This supports
-KCS, SMIC, and may support BT in the future. Unless you have your own
-custom interface, you probably need to use this.
+ipmi_si - A driver for various system interfaces. This supports KCS,
+SMIC, and BT interfaces. Unless you have an SMBus interface or your
+own custom interface, you probably need to use this.
ipmi_smb - A driver for accessing BMCs on the SMBus. It uses the
I2C kernel driver's SMBus interfaces to send and receive IPMI messages
over the SMBus.
-af_ipmi - A network socket interface to IPMI. This doesn't take up
-a character device in your system.
+ipmi_watchdog - IPMI requires systems to have a very capable watchdog
+timer. This driver implements the standard Linux watchdog timer
+interface on top of the IPMI message handler.
+
+ipmi_poweroff - Some systems support the ability to be turned off via
+IPMI commands.
-Note that the KCS-only interface ahs been removed.
+These are all individually selectable via configuration options.
+
+Note that the KCS-only interface has been removed. The af_ipmi driver
+is no longer supported and has been removed because it was impossible
+to do 32 bit emulation on 64-bit kernels with it.
Much documentation for the interface is in the include files. The
IPMI include files are:
modprobe ipmi_smb.o
addr=<adapter1>,<i2caddr1>[,<adapter2>,<i2caddr2>[,...]]
dbg=<flags1>,<flags2>...
- [defaultprobe=0] [dbg_probe=1]
+ [defaultprobe=1] [dbg_probe=1]
The addresses are specified in pairs, the first is the adapter ID and the
second is the I2C address on that adapter.
device to close it, or the timer will not stop. This is a new semantic
for the driver, but makes it consistent with the rest of the watchdog
drivers in Linux.
+
+
+Panic Timeouts
+--------------
+
+The OpenIPMI driver supports the ability to put semi-custom and custom
+events in the system event log if a panic occurs. if you enable the
+'Generate a panic event to all BMCs on a panic' option, you will get
+one event on a panic in a standard IPMI event format. If you enable
+the 'Generate OEM events containing the panic string' option, you will
+also get a bunch of OEM events holding the panic string.
+
+
+The field settings of the events are:
+* Generator ID: 0x21 (kernel)
+* EvM Rev: 0x03 (this event is formatting in IPMI 1.0 format)
+* Sensor Type: 0x20 (OS critical stop sensor)
+* Sensor #: The first byte of the panic string (0 if no panic string)
+* Event Dir | Event Type: 0x6f (Assertion, sensor-specific event info)
+* Event Data 1: 0xa1 (Runtime stop in OEM bytes 2 and 3)
+* Event data 2: second byte of panic string
+* Event data 3: third byte of panic string
+See the IPMI spec for the details of the event layout. This event is
+always sent to the local management controller. It will handle routing
+the message to the right place
+
+Other OEM events have the following format:
+Record ID (bytes 0-1): Set by the SEL.
+Record type (byte 2): 0xf0 (OEM non-timestamped)
+byte 3: The slave address of the card saving the panic
+byte 4: A sequence number (starting at zero)
+The rest of the bytes (11 bytes) are the panic string. If the panic string
+is longer than 11 bytes, multiple messages will be sent with increasing
+sequence numbers.
+
+Because you cannot send OEM events using the standard interface, this
+function will attempt to find an SEL and add the events there. It
+will first query the capabilities of the local management controller.
+If it has an SEL, then they will be stored in the SEL of the local
+management controller. If not, and the local management controller is
+an event generator, the event receiver from the local management
+controller will be queried and the events sent to the SEL on that
+device. Otherwise, the events go nowhere since there is nowhere to
+send them.
+
+
+Poweroff
+--------
+
+If the poweroff capability is selected, the IPMI driver will install
+a shutdown function into the standard poweroff function pointer. This
+is in the ipmi_poweroff module. When the system requests a powerdown,
+it will send the proper IPMI commands to do this. This is supported on
+several platforms.
+
+There is a module parameter named "poweroff_control" that may either be zero
+(do a power down) or 2 (do a power cycle, power the system off, then power
+it on in a few seconds). Setting ipmi_poweroff.poweroff_control=x will do
+the same thing on the kernel command line. The parameter is also available
+via the proc filesystem in /proc/ipmi/poweroff_control. Note that if the
+system does not support power cycling, it will always to the power off.
+
+Note that if you have ACPI enabled, the system will prefer using ACPI to
+power off.

+Block io priorities
+===================
+
+
+Intro
+-----
+
+With the introduction of cfq v3 (aka cfq-ts or time sliced cfq), basic io
+priorities is supported for reads on files. This enables users to io nice
+processes or process groups, similar to what has been possible to cpu
+scheduling for ages. This document mainly details the current possibilites
+with cfq, other io schedulers do not support io priorities so far.
+
+Scheduling classes
+------------------
+
+CFQ implements three generic scheduling classes that determine how io is
+served for a process.
+
+IOPRIO_CLASS_RT: This is the realtime io class. This scheduling class is given
+higher priority than any other in the system, processes from this class are
+given first access to the disk every time. Thus it needs to be used with some
+care, one io RT process can starve the entire system. Within the RT class,
+there are 8 levels of class data that determine exactly how much time this
+process needs the disk for on each service. In the future this might change
+to be more directly mappable to performance, by passing in a wanted data
+rate instead.
+
+IOPRIO_CLASS_BE: This is the best-effort scheduling class, which is the default
+for any process that hasn't set a specific io priority. The class data
+determines how much io bandwidth the process will get, it's directly mappable
+to the cpu nice levels just more coarsely implemented. 0 is the highest
+BE prio level, 7 is the lowest. The mapping between cpu nice level and io
+nice level is determined as: io_nice = (cpu_nice + 20) / 5.
+
+IOPRIO_CLASS_IDLE: This is the idle scheduling class, processes running at this
+level only get io time when no one else needs the disk. The idle class has no
+class data, since it doesn't really apply here.
+
+Tools
+-----
+
+See below for a sample ionice tool. Usage:
+
+# ionice -c<class> -n<level> -p<pid>
+
+If pid isn't given, the current process is assumed. IO priority settings
+are inherited on fork, so you can use ionice to start the process at a given
+level:
+
+# ionice -c2 -n0 /bin/ls

-2.1 Powersave
+2.2 Powersave
-------------
The CPUfreq governor "powersave" sets the CPU statically to the
scaling_max_freq.
-2.2 Userspace
+2.3 Userspace
-------------
The CPUfreq governor "userspace" allows the user, or any userspace
directory.
+2.4 Ondemand
+------------
+
+The CPUfreq govenor "ondemand" sets the CPU depending on the
+current usage. To do this the CPU must have the capability to
+switch the frequency very fast.
+
+
3. The Governor Interface in the CPUfreq Core
=============================================
If a cpuset is cpu or mem exclusive, no other cpuset, other than a direct
ancestor or descendent, may share any of the same CPUs or Memory Nodes.
+A cpuset that is cpu exclusive has a sched domain associated with it.
+The sched domain consists of all cpus in the current cpuset that are not
+part of any exclusive child cpusets.
+This ensures that the scheduler load balacing code only balances
+against the cpus that are in the sched domain as defined above and not
+all of the cpus in the system. This removes any overhead due to
+load balancing code trying to pull tasks outside of the cpu exclusive
+cpuset only to be prevented by the tasks' cpus_allowed mask.
User level code may create and destroy cpusets by name in the cpuset
virtual file system, manage the attributes and permissions of these
and a database), or
* NUMA systems running large HPC applications with demanding
performance characteristics.
+ * Also cpu_exclusive cpusets are useful for servers running orthogonal
+ workloads such as RT applications requiring low latency and HPC
+ applications that are throughput sensitive
These subsets, or "soft partitions" must be able to be dynamically
adjusted, as the job mix changes, without impacting other concurrently
- A cpuset may be marked exclusive, which ensures that no other
cpuset (except direct ancestors and descendents) may contain
any overlapping CPUs or Memory Nodes.
+ Also a cpu_exclusive cpuset would be associated with a sched
+ domain.
- You can list all the tasks (by pid) attached to any cpuset.
The implementation of cpusets requires a few, simple hooks
allowed in that tasks cpuset.
- in sched.c migrate_all_tasks(), to keep migrating tasks within
the CPUs allowed by their cpuset, if possible.
+ - in sched.c, a new API partition_sched_domains for handling
+ sched domain changes associated with cpu_exclusive cpusets
+ and related changes in both sched.c and arch/ia64/kernel/domain.c
- in the mbind and set_mempolicy system calls, to mask the requested
Memory Nodes by what's allowed in that tasks cpuset.
- in page_alloc, to restrict memory to allowed nodes.

-
-1. How to use?
-NOTE: This driver was developed using Linux 2.6.6.,
-it is working with 2.6.7 and above.
-
-Linux 2.4.x support is not planned, but patches are very welcome.
-
-NOTE: I'm using Debian testing, so the following explaination (especially
-the hotplug-path) needn't match your system, but probably it will :).
-
-The driver is included in the kernel since Linux 2.6.10.
-
-1.1. Firmware
-
-The USB driver needs to download a firmware to start working.
-
-You can either use "get_dvb_firmware dibusb" to download the firmware or you
-can get it directly via
-
-for USB1.1 (AN2135)
-http://www.linuxtv.org/downloads/firmware/dvb-dibusb-5.0.0.11.fw
-
-for USB1.1 (AN2235) (a few Artec T1 devices)
-http://www.linuxtv.org/downloads/firmware/dvb-dibusb-an2235-1.fw
-
-for USB2.0 (FX2) Hauppauge, DiBcom
-http://www.linuxtv.org/downloads/firmware/dvb-dibusb-6.0.0.5.fw
-
-for USB2.0 ADSTech/Kworld USB2.0
-http://www.linuxtv.org/downloads/firmware/dvb-dibusb-adstech-usb2-1.fw
-
-for USB2.0 HanfTek
-http://www.linuxtv.org/downloads/firmware/dvb-dibusb-an2235-1.fw
-
-
-1.2. Compiling
-
-Since the driver is in the linux kernel, activating the driver in
-your favorite config-environment should sufficient. I recommend
-to compile the driver as module. Hotplug does the rest.
-
-1.3. Loading the drivers
-
-Hotplug is able to load the driver, when it is needed (because you plugged
-in the device).
-
-If you want to enable debug output, you have to load the driver manually and
-from withing the dvb-kernel cvs repository.
-
-first have a look, which debug level are available:
-
-modinfo dib3000mb
-modinfo dib3000-common
-modinfo dib3000mc
-modinfo dvb-dibusb
-
-modprobe dib3000-common debug=<level>
-modprobe dib3000mb debug=<level>
-modprobe dib3000mc debug=<level>
-modprobe dvb-dibusb debug=<level>
-
-should do the trick.
-
-When the driver is loaded successfully, the firmware file was in
-the right place and the device is connected, the "Power"-LED should be
-turned on.
-
-At this point you should be able to start a dvb-capable application. For myself
-I used mplayer, dvbscan, tzap and kaxtv, they are working. Using the device
-in vdr is working now also.
-
-2. Known problems and bugs
-
-- Don't remove the USB device while running an DVB application, your system will die.
-
-2.1. Adding support for devices
-
-It is not possible to determine the range of devices based on the DiBcom
-reference designs. This is because the reference design of DiBcom can be sold
-to thirds, without telling DiBcom (so done with the Twinhan VP7041 and
-the HAMA device).
-
-When you think you have a device like this and the driver does not recognizes it,
-please send the ****load*.inf and the ****cap*.inf of the Windows driver to me.
-
-Sometimes the Vendor or Product ID is identical to the ones of Twinhan, even
-though it is not a Twinhan device (e.g. HAMA), then please send me the name
-of the device. I will add it to this list in order to make this clear to
-others.
-
-If you are familar with C you can also add the VID and PID of the device to
-the dvb-dibusb-core.c-file and create a patch and send it over to me or to
-the linux-dvb mailing list, _after_ you have tried compiling and modprobing
-it.
-
-2.2. USB1.1 Bandwidth limitation
-
-Most of the currently supported devices are USB1.1 and thus they have a
-maximum bandwidth of about 5-6 MBit/s when connected to a USB2.0 hub.
-This is not enough for receiving the complete transport stream of a
-DVB-T channel (which can be about 16 MBit/s). Normally this is not a
-problem, if you only want to watch TV (this does not apply for HDTV),
-but watching a channel while recording another channel on the same
-frequency simply does not work very well. This applies to all USB1.1
-DVB-T devices, not just dibusb)
-
-Update: For the USB1.1 and VDR some work has been done (patches and comments
-are still very welcome). Maybe the problem is solved in the meantime because I
-now use the dmx_sw_filter function instead of dmx_sw_filter_packet. I hope the
-linux-dvb software filter is able to get the best of the garbled TS.
-
-The bug, where the TS is distorted by a heavy usage of the device is gone
-definitely. All dibusb-devices I was using (Twinhan, Kworld, DiBcom) are
-working like charm now with VDR. Sometimes I even was able to record a channel
-and watch another one.
-
-2.3. Comments
-
-Patches, comments and suggestions are very very welcome.
-
-3. Acknowledgements

+Documentation for dvb-usb-framework module and its devices
+
+Idea behind the dvb-usb-framework
+=================================
+
+In March 2005 I got the new Twinhan USB2.0 DVB-T device. They provided specs and a firmware.
+
+Quite keen I wanted to put the driver (with some quirks of course) into dibusb.
+After reading some specs and doing some USB snooping, it realized, that the
+dibusb-driver would be a complete mess afterwards. So I decided to do it in a
+different way: With the help of a dvb-usb-framework.
+
+The framework provides generic functions (mostly kernel API calls), such as:
+
+- Transport Stream URB handling in conjunction with dvb-demux-feed-control
+ (bulk and isoc (TODO) are supported)
+- registering the device for the DVB-API
+- registering an I2C-adapter if applicable
+- remote-control/input-device handling
+- firmware requesting and loading (currently just for the Cypress USB
+ controller)
+- other functions/methods which can be shared by several drivers (such as
+ functions for bulk-control-commands)
+
+The source code of the particular DVB USB devices does just the communication
+with the device via the bus. The connection between the DVB-API-functionality
+is done via callbacks, assigned in a static device-description (struct
+dvb_usb_device) each device-driver has to have.
+
+For an example have a look in drivers/media/dvb/dvb-usb/vp7045*.
+
+Objective is to migrate all the usb-devices (dibusb, cinergyT2, maybe the
+ttusb; flexcop-usb already benefits from the generic flexcop-device) to use
+the dvb-usb-lib.
+
+TODO: dynamic enabling and disabling of the pid-filter in regard to number of
+feeds requested.

+
+1. How to use?
+1.1. Firmware
+
+Most of the USB drivers need to download a firmware to start working.
+
+for USB1.1 (AN2135) you need: dvb-usb-dibusb-5.0.0.11.fw
+for USB2.0 HanfTek: dvb-usb-umt-010-02.fw
+for USB2.0 DiBcom: dvb-usb-dibusb-6.0.0.8.fw
+for USB2.0 AVerMedia AverTV DVB-T USB2: dvb-usb-avertv-a800-01.fw
+for USB2.0 TwinhanDTV Alpha/MagicBox II: dvb-usb-vp7045-01.fw
+
+The files can be found on http://www.linuxtv.org/download/firmware/ .
+
+We do not have the permission (yet) to publish the following firmware-files.
+You'll need to extract them from the windows drivers.
+
+You should be able to use "get_dvb_firmware dvb-usb" to get the firmware:
+
+for USB1.1 (AN2235) (a few Artec T1 devices): dvb-usb-dibusb-an2235-01.fw
+for USB2.0 Hauppauge: dvb-usb-nova-t-usb2-01.fw
+for USB2.0 ADSTech/Kworld USB2.0: dvb-usb-adstech-usb2-01.fw
+for USB2.0 Yakumo/Typhoon/Hama: dvb-usb-dtt200u-01.fw
+
+1.2. Compiling
+
+Since the driver is in the linux kernel, activating the driver in
+your favorite config-environment should sufficient. I recommend
+to compile the driver as module. Hotplug does the rest.
+
+If you use dvb-kernel enter the build-2.6 directory run 'make' and 'insmod.sh
+load' afterwards.
+
+1.3. Loading the drivers
+
+Hotplug is able to load the driver, when it is needed (because you plugged
+in the device).
+
+If you want to enable debug output, you have to load the driver manually and
+from withing the dvb-kernel cvs repository.
+
+first have a look, which debug level are available:
+
+modinfo dvb-usb
+modinfo dvb-usb-vp7045
+etc.
+
+modprobe dvb-usb debug=<level>
+modprobe dvb-usb-vp7045 debug=<level>
+etc.
+
+should do the trick.
+
+When the driver is loaded successfully, the firmware file was in
+the right place and the device is connected, the "Power"-LED should be
+turned on.
+
+At this point you should be able to start a dvb-capable application. I'm use
+(t|s)zap, mplayer and dvbscan to test the basics. VDR-xine provides the
+long-term test scenario.
+
+2. Known problems and bugs
+
+- Don't remove the USB device while running an DVB application, your system
+ will go crazy or die most likely.
+
+2.1. Adding support for devices
+
+TODO
+
+2.2. USB1.1 Bandwidth limitation
+
+A lot of the currently supported devices are USB1.1 and thus they have a
+maximum bandwidth of about 5-6 MBit/s when connected to a USB2.0 hub.
+This is not enough for receiving the complete transport stream of a
+DVB-T channel (which is about 16 MBit/s). Normally this is not a
+problem, if you only want to watch TV (this does not apply for HDTV),
+but watching a channel while recording another channel on the same
+frequency simply does not work very well. This applies to all USB1.1
+DVB-T devices, not just the dvb-usb-devices)
+
+The bug, where the TS is distorted by a heavy usage of the device is gone
+definitely. All dvb-usb-devices I was using (Twinhan, Kworld, DiBcom) are
+working like charm now with VDR. Sometimes I even was able to record a channel
+and watch another one.
+
+2.3. Comments
+
+Patches, comments and suggestions are very very welcome.

+Execute-in-place for file mappings
+----------------------------------
+
+Motivation
+----------
+File mappings are performed by mapping page cache pages to userspace. In
+addition, read&write type file operations also transfer data from/to the page
+cache.
+
+For memory backed storage devices that use the block device interface, the page
+cache pages are in fact copies of the original storage. Various approaches
+exist to work around the need for an extra copy. The ramdisk driver for example
+does read the data into the page cache, keeps a reference, and discards the
+original data behind later on.
+
+Execute-in-place solves this issue the other way around: instead of keeping
+data in the page cache, the need to have a page cache copy is eliminated
+completely. With execute-in-place, read&write type operations are performed
+directly from/to the memory backed storage device. For file mappings, the
+storage device itself is mapped directly into userspace.
+
+This implementation was initialy written for shared memory segments between
+different virtual machines on s390 hardware to allow multiple machines to
+share the same binaries and libraries.
+
+Implementation
+--------------
+Execute-in-place is implemented in three steps: block device operation,
+address space operation, and file operations.
+
+A block device operation named direct_access is used to retrieve a
+reference (pointer) to a block on-disk. The reference is supposed to be
+cpu-addressable, physical address and remain valid until the release operation
+is performed. A struct block_device reference is used to address the device,
+and a sector_t argument is used to identify the individual block. As an
+alternative, memory technology devices can be used for this.
+
+The block device operation is optional, these block devices support it as of
+today:
+- dcssblk: s390 dcss block device driver
+
+An address space operation named get_xip_page is used to retrieve reference
+to a struct page. To address the target page, a reference to an address_space,
+and a sector number is provided. A 3rd argument indicates whether the
+function should allocate blocks if needed.
+
+This address space operation is mutually exclusive with readpage&writepage that
+do page cache read/write operations.
+The following filesystems support it as of today:
+- ext2: the second extended filesystem, see Documentation/filesystems/ext2.txt
+
+A set of file operations that do utilize get_xip_page can be found in
+mm/filemap_xip.c . The following file operation implementations are provided:
+- aio_read/aio_write
+- readv/writev
+- sendfile
+
+The generic file operations do_sync_read/do_sync_write can be used to implement
+classic synchronous IO calls.
+
+Shortcomings
+------------
+This implementation is limited to storage devices that are cpu addressable at
+all times (no highmem or such). It works well on rom/ram, but enhancements are
+needed to make it work with flash in read+write mode.
+Putting the Linux kernel and/or its modules on a xip filesystem does not mean
+they are not copied.

+Documentation for kdump - the kexec-based crash dumping solution
+================================================================
+
+DESIGN
+======
+
+Kdump uses kexec to reboot to a second kernel whenever a dump needs to be taken.
+This second kernel is booted with very little memory. The first kernel reserves
+the section of memory that the second kernel uses. This ensures that on-going
+DMA from the first kernel does not corrupt the second kernel.
+
+All the necessary information about Core image is encoded in ELF format and
+stored in reserved area of memory before crash. Physical address of start of
+ELF header is passed to new kernel through command line parameter elfcorehdr=.
+
+On i386, the first 640 KB of physical memory is needed to boot, irrespective
+of where the kernel loads. Hence, this region is backed up by kexec just before
+rebooting into the new kernel.
+
+In the second kernel, "old memory" can be accessed in two ways.
+
+- The first one is through a /dev/oldmem device interface. A capture utility
+ can read the device file and write out the memory in raw format. This is raw
+ dump of memory and analysis/capture tool should be intelligent enough to
+ determine where to look for the right information. ELF headers (elfcorehdr=)
+ can become handy here.
+
+- The second interface is through /proc/vmcore. This exports the dump as an ELF
+ format file which can be written out using any file copy command
+ (cp, scp, etc). Further, gdb can be used to perform limited debugging on
+ the dump file. This method ensures methods ensure that there is correct
+ ordering of the dump pages (corresponding to the first 640 KB that has been
+ relocated).
+
+SETUP
+=====
+
+1) Download http://www.xmission.com/~ebiederm/files/kexec/kexec-tools-1.101.tar.gz
+ and apply http://lse.sourceforge.net/kdump/patches/kexec-tools-1.101-kdump.patch
+ and after that build the source.
+
+2) Download and build the appropriate (latest) kexec/kdump (-mm) kernel
+ patchset and apply it to the vanilla kernel tree.
+
+ Two kernels need to be built in order to get this feature working.
+
+ A) First kernel:
+ a) Enable "kexec system call" feature (in Processor type and features).
+ CONFIG_KEXEC=y
+ b) This kernel's physical load address should be the default value of
+ 0x100000 (0x100000, 1 MB) (in Processor type and features).
+ CONFIG_PHYSICAL_START=0x100000
+ c) Enable "sysfs file system support" (in Pseudo filesystems).
+ CONFIG_SYSFS=y
+ d) Boot into first kernel with the command line parameter "crashkernel=Y@X".
+ Use appropriate values for X and Y. Y denotes how much memory to reserve
+ for the second kernel, and X denotes at what physical address the reserved
+ memory section starts. For example: "crashkernel=64M@16M".
+
+ B) Second kernel:
+ a) Enable "kernel crash dumps" feature (in Processor type and features).

+
+5) System reboots into the second kernel when a panic occurs. A module can be
+ written to force the panic or "ALT-SysRq-c" can be used initiate a crash
+ dump for testing purposes.
+
+6) Write out the dump file using
+
+ cp /proc/vmcore <dump-file>
+
+ Dump memory can also be accessed as a /dev/oldmem device for a linear/raw
+ view. To create the device, type:
+
+ mknod /dev/oldmem c 1 12
+
+ Use "dd" with suitable options for count, bs and skip to access specific
+ portions of the dump.
+
+ Entire memory: dd if=/dev/oldmem of=oldmem.001
+
+ANALYSIS
+========
+
+Limited analysis can be done using gdb on the dump file copied out of
+/proc/vmcore. Use vmlinux built with -g and run
+
+ gdb vmlinux <dump-file>
+
+Stack trace for the task on processor 0, register display, memory display
+work fine.
+
+Note: gdb cannot analyse core files generated in ELF64 format for i386.
+
+TODO
+====
+
+1) Provide a kernel pages filtering mechanism so that core file size is not
+ insane on systems having huge memory banks.
+2) Modify "crash" tool to make it recognize this dump.

===============
Dealing with keys is fairly straightforward. Firstly, the kernel service
registers its type, then it searches for a key of that type. It should retain
the key as long as it has need of it, and then it should release it. For a

-open call, and the key released upon close. How to deal with conflicting keys

+===================================
+NOTES ON ACCESSING PAYLOAD CONTENTS
+===================================
+
+The simplest payload is just a number in key->payload.value. In this case,
+there's no need to indulge in RCU or locking when accessing the payload.
+
+More complex payload contents must be allocated and a pointer to them set in
+key->payload.data. One of the following ways must be selected to access the
+data:
+
+ (1) Unmodifyable key type.
+
+ If the key type does not have a modify method, then the key's payload can
+ be accessed without any form of locking, provided that it's known to be
+ instantiated (uninstantiated keys cannot be "found").
+
+ (2) The key's semaphore.
+
+ The semaphore could be used to govern access to the payload and to control
+ the payload pointer. It must be write-locked for modifications and would
+ have to be read-locked for general access. The disadvantage of doing this
+ is that the accessor may be required to sleep.
+
+ (3) RCU.
+
+ RCU must be used when the semaphore isn't already held; if the semaphore
+ is held then the contents can't change under you unexpectedly as the
+ semaphore must still be used to serialise modifications to the key. The
+ key management code takes care of this for the key type.
+
+ However, this means using:
+
+ rcu_read_lock() ... rcu_dereference() ... rcu_read_unlock()
+
+ to read the pointer, and:
+
+ rcu_dereference() ... rcu_assign_pointer() ... call_rcu()
+
+ to set the pointer and dispose of the old contents after a grace period.
+ Note that only the key type should ever modify a key's payload.
+
+ Furthermore, an RCU controlled payload must hold a struct rcu_head for the
+ use of call_rcu() and, if the payload is of variable size, the length of
+ the payload. key->datalen cannot be relied upon to be consistent with the
+ payload just dereferenced if the key's semaphore is not held.

+This driver provides kernel support for Davicom DM9102(A)/DM9132/DM9801 ethernet cards ( CNET
+10/100 ethernet cards uses Davicom chipset too, so this driver supports CNET cards too ).If you
+didn't compile this driver as a module, it will automatically load itself on boot and print a
+line similar to :
- A. Compiler command:
+ dmfe: Davicom DM9xxx net driver, version 1.36.4 (2002-01-17)
- A-1: For normal single or multiple processor kernel
- "gcc -DMODULE -D__KERNEL__ -I/usr/src/linux/net/inet -Wall
- -Wstrict-prototypes -O6 -c dmfe.c"
+If you compiled this driver as a module, you have to load it on boot.You can load it with command :
- A-2: For single or multiple processor with kernel module version function
- "gcc -DMODULE -DMODVERSIONS -D__KERNEL__ -I/usr/src/linux/net/inet
- -Wall -Wstrict-prototypes -O6 -c dmfe.c"
+ insmod dmfe
+This way it will autodetect the device mode.This is the suggested way to load the module.Or you can pass
+a mode= setting to module while loading, like :
- B. The following steps teach you how to activate a DM9102 board:
+ insmod dmfe mode=0 # Force 10M Half Duplex
+ insmod dmfe mode=1 # Force 100M Half Duplex
+ insmod dmfe mode=4 # Force 10M Full Duplex
+ insmod dmfe mode=5 # Force 100M Full Duplex
- 1. Used the upper compiler command to compile dmfe.c
+Next you should configure your network interface with a command similar to :
- 2. Insert dmfe module into kernel
- "insmod dmfe" ;;Auto Detection Mode (Suggest)
- "insmod dmfe mode=0" ;;Force 10M Half Duplex
- "insmod dmfe mode=1" ;;Force 100M Half Duplex
- "insmod dmfe mode=4" ;;Force 10M Full Duplex
- "insmod dmfe mode=5" ;;Force 100M Full Duplex
+ ifconfig eth0 172.22.3.18
+ ^^^^^^^^^^^
+ Your IP Adress
- 3. Config a dm9102 network interface
- "ifconfig eth0 172.22.3.18"
- ^^^^^^^^^^^ Your IP address
+Then you may have to modify the default routing table with command :
- 4. Activate the IP routing table. For some distributions, it is not
- necessary. You can type "route" to check.
+ route add default eth0
- "route add default eth0"
+Now your ethernet card should be up and running.
- 5. Well done. Your DM9102 adapter is now activated.
+TODO:
- C. Object files description:
- 1. dmfe_rh61.o: For Redhat 6.1
+Implement pci_driver::suspend() and pci_driver::resume() power management methods.
+Check on 64 bit boxes.
+Check and fix on big endian boxes.
+Test and make sure PCI latency is now correct for all cases.
- If you can make sure your kernel version, you can rename
- to dmfe.o and directly use it without re-compiling.

-Linux WAN Router Utilities Package
-------------------------------------------------------------------------------
-Version 2.2.1
-Mar 28, 2001
-Author: Nenad Corbic <ncorbic@sangoma.com>
-Copyright (c) 1995-2001 Sangoma Technologies Inc.
-------------------------------------------------------------------------------
-
-INTRODUCTION
-
-Wide Area Networks (WANs) are used to interconnect Local Area Networks (LANs)
-and/or stand-alone hosts over vast distances with data transfer rates
-significantly higher than those achievable with commonly used dial-up
-connections.
-
-Usually an external device called `WAN router' sitting on your local network
-or connected to your machine's serial port provides physical connection to
-WAN. Although router's job may be as simple as taking your local network
-traffic, converting it to WAN format and piping it through the WAN link, these
-devices are notoriously expensive, with prices as much as 2 - 5 times higher
-then the price of a typical PC box.
-
-Alternatively, considering robustness and multitasking capabilities of Linux,
-an internal router can be built (most routers use some sort of stripped down
-Unix-like operating system anyway). With a number of relatively inexpensive WAN
-interface cards available on the market, a perfectly usable router can be
-built for less than half a price of an external router. Yet a Linux box
-acting as a router can still be used for other purposes, such as fire-walling,
-running FTP, WWW or DNS server, etc.
-
-This kernel module introduces the notion of a WAN Link Driver (WLD) to Linux
-operating system and provides generic hardware-independent services for such
-drivers. Why can existing Linux network device interface not be used for
-this purpose? Well, it can. However, there are a few key differences between
-a typical network interface (e.g. Ethernet) and a WAN link.
-
-Many WAN protocols, such as X.25 and frame relay, allow for multiple logical
-connections (known as `virtual circuits' in X.25 terminology) over a single
-physical link. Each such virtual circuit may (and almost always does) lead
-to a different geographical location and, therefore, different network. As a
-result, it is the virtual circuit, not the physical link, that represents a
-route and, therefore, a network interface in Linux terms.
-
-To further complicate things, virtual circuits are usually volatile in nature
-(excluding so called `permanent' virtual circuits or PVCs). With almost no
-time required to set up and tear down a virtual circuit, it is highly desirable
-to implement on-demand connections in order to minimize network charges. So
-unlike a typical network driver, the WAN driver must be able to handle multiple
-network interfaces and cope as multiple virtual circuits come into existence
-and go away dynamically.
-
-Last, but not least, WAN configuration is much more complex than that of say
-Ethernet and may well amount to several dozens of parameters. Some of them
-are "link-wide" while others are virtual circuit-specific. The same holds
-true for WAN statistics which is by far more extensive and extremely useful
-when troubleshooting WAN connections. Extending the ifconfig utility to suit
-these needs may be possible, but does not seem quite reasonable. Therefore, a
-WAN configuration utility and corresponding application programmer's interface
-is needed for this purpose.
-
-Most of these problems are taken care of by this module. Its goal is to
-provide a user with more-or-less standard look and feel for all WAN devices and
-assist a WAN device driver writer by providing common services, such as:
-
- o User-level interface via /proc file system
- o Centralized configuration
- o Device management (setup, shutdown, etc.)
- o Network interface management (dynamic creation/destruction)
- o Protocol encapsulation/decapsulation
-
-To ba able to use the Linux WAN Router you will also need a WAN Tools package
-available from
-
- ftp.sangoma.com/pub/linux/current_wanpipe/wanpipe-X.Y.Z.tgz
-
-where vX.Y.Z represent the wanpipe version number.

-ACKNOWLEDGEMENTS
-
-This product is based on the WANPIPE(tm) Multiprotocol WAN Router developed
-by Sangoma Technologies Inc. for Linux 2.0.x and 2.2.x. Success of the WANPIPE
-together with the next major release of Linux kernel in summer 1996 commanded
-adequate changes to the WANPIPE code to take full advantage of new Linux
-features.
-
-Instead of continuing developing proprietary interface tied to Sangoma WAN
-cards, we decided to separate all hardware-independent code into a separate
-module and defined two levels of interfaces - one for user-level applications
-and another for kernel-level WAN drivers. WANPIPE is now implemented as a
-WAN driver compliant with the WAN Link Driver interface. Also a general
-purpose WAN configuration utility and a set of shell scripts was developed to
-support WAN router at the user level.
-
-Many useful ideas concerning hardware-independent interface implementation
-were given by Mike McLagan <mike.mclagan@linux.org> and his implementation
-of the Frame Relay router and drivers for Sangoma cards (dlci/sdla).
-
-With the new implementation of the APIs being incorporated into the WANPIPE,
-a special thank goes to Alan Cox in providing insight into BSD sockets.
-
-Special thanks to all the WANPIPE users who performed field-testing, reported
-bugs and made valuable comments and suggestions that help us to improve this
-product.
-
-
-
-NEW IN THIS RELEASE

-
-beta-2.1.4 Jul 2000 o Dynamic interface configuration:
- Network interfaces reflect the state
- of protocol layer. If the protocol becomes
- disconnected, driver will bring down
- the interface. Once the protocol reconnects
- the interface will be brought up.
-
- Note: This option is turned off by default.
-
- o Dynamic wanrouter setup using 'wanconfig':
- wanconfig utility can be used to
- shutdown,restart,start or reconfigure
- a virtual circuit dynamically.
-
- Frame Relay: Each DLCI can be:
- created,stopped,restarted and reconfigured
- dynamically using wanconfig.
-
- ex: wanconfig card wanpipe1 dev wp1_fr16 up
-
- o Wanrouter startup via command line arguments:
- wanconfig also supports wanrouter startup via command line
- arguments. Thus, there is no need to create a wanpipe#.conf
- configuration file.
-
- o Socket based x25api update/bug fixes.
- Added support for LCN numbers greater than 255.
- Option to pass up modem messages.
- Provided a PCI IRQ check, so a single S514
- card is guaranteed to have a non-sharing interrupt.
-
- o Fixes to the wancfg utility.
- o New FT1 debugging support via *pipemon utilities.
- o Frame Relay ARP support Enabled.
-
-beta3-2.1.4 Jul 2000 o X25 M_BIT Problem fix.
- o Added the Multi-Port PPP
- Updated utilites for the Multi-Port PPP.
-
-2.1.4 Aut 2000
- o In X25API:
- Maximum packet an application can send
- to the driver has been extended to 4096 bytes.
-
- Fixed the x25 startup bug. Enable
- communications only after all interfaces
- come up. HIGH SVC/PVC is used to calculate
- the number of channels.
- Enable protocol only after all interfaces
- are enabled.
-
- o Added an extra state to the FT1 config, kernel module.
- o Updated the pipemon debuggers.
-
- o Blocked the Multi-Port PPP from running on kernels
- 2.2.16 or greater, due to syncppp kernel module
- change.
-
-beta1-2.1.5 Nov 15 2000
- o Fixed the MulitPort PPP Support for kernels 2.2.16 and above.
- 2.2.X kernels only
-
- o Secured the driver UDP debugging calls
- - All illegal netowrk debugging calls are reported to
- the log.
- - Defined a set of allowed commands, all other denied.
-
- o Cpipemon
- - Added set FT1 commands to the cpipemon. Thus CSU/DSU
- configuraiton can be performed using cpipemon.
- All systems that cannot run cfgft1 GUI utility should
- use cpipemon to configure the on board CSU/DSU.
-
-
- o Keyboard Led Monitor/Debugger
- - A new utilty /usr/sbin/wpkbdmon uses keyboard leds
- to convey operatinal statistic information of the
- Sangoma WANPIPE cards.
- NUM_LOCK = Line State (On=connected, Off=disconnected)
- CAPS_LOCK = Tx data (On=transmitting, Off=no tx data)
- SCROLL_LOCK = Rx data (On=receiving, Off=no rx data
-
- o Hardware probe on module load and dynamic device allocation
- - During WANPIPE module load, all Sangoma cards are probed
- and found information is printed in the /var/log/messages.
- - If no cards are found, the module load fails.
- - Appropriate number of devices are dynamically loaded
- based on the number of Sangoma cards found.
-
- Note: The kernel configuraiton option
- CONFIG_WANPIPE_CARDS has been taken out.
-
- o Fixed the Frame Relay and Chdlc network interfaces so they are
- compatible with libpcap libraries. Meaning, tcpdump, snort,
- ethereal, and all other packet sniffers and debuggers work on
- all WANPIPE netowrk interfaces.
- - Set the network interface encoding type to ARPHRD_PPP.
- This tell the sniffers that data obtained from the
- network interface is in pure IP format.
- Fix for 2.2.X kernels only.
-
- o True interface encoding option for Frame Relay and CHDLC
- - The above fix sets the network interface encoding
- type to ARPHRD_PPP, however some customers use
- the encoding interface type to determine the
- protocol running. Therefore, the TURE ENCODING
- option will set the interface type back to the
- original value.
-
- NOTE: If this option is used with Frame Relay and CHDLC
- libpcap library support will be broken.
- i.e. tcpdump will not work.
- Fix for 2.2.x Kernels only.
-
- o Ethernet Bridgind over Frame Relay
- - The Frame Relay bridging has been developed by
- Kristian Hoffmann and Mark Wells.
- - The Linux kernel bridge is used to send ethernet
- data over the frame relay links.
- For 2.2.X Kernels only.
-
- o Added extensive 2.0.X support. Most new features of
- 2.1.5 for protocols Frame Relay, PPP and CHDLC are
- supported under 2.0.X kernels.
-
-beta1-2.2.0 Dec 30 2000
- o Updated drivers for 2.4.X kernels.
- o Updated drivers for SMP support.
- o X25API is now able to share PCI interrupts.
- o Took out a general polling routine that was used
- only by X25API.
- o Added appropriate locks to the dynamic reconfiguration
- code.
- o Fixed a bug in the keyboard debug monitor.
-
-beta2-2.2.0 Jan 8 2001
- o Patches for 2.4.0 kernel
- o Patches for 2.2.18 kernel
- o Minor updates to PPP and CHLDC drivers.
- Note: No functinal difference.
-
-beta3-2.2.9 Jan 10 2001
- o I missed the 2.2.18 kernel patches in beta2-2.2.0
- release. They are included in this release.
-
-Stable Release
-2.2.0 Feb 01 2001
- o Bug fix in wancfg GUI configurator.
- The edit function didn't work properly.
-
-
-bata1-2.2.1 Feb 09 2001
- o WANPIPE TTY Driver emulation.
- Two modes of operation Sync and Async.
- Sync: Using the PPPD daemon, kernel SyncPPP layer
- and the Wanpipe sync TTY driver: a PPP protocol
- connection can be established via Sangoma adapter, over
- a T1 leased line.
-
- The 2.4.0 kernel PPP layer supports MULTILINK
- protocol, that can be used to bundle any number of Sangoma
- adapters (T1 lines) into one, under a single IP address.
- Thus, efficiently obtaining multiple T1 throughput.
-
- NOTE: The remote side must also implement MULTILINK PPP
- protocol.
-
- Async:Using the PPPD daemon, kernel AsyncPPP layer
- and the WANPIPE async TTY driver: a PPP protocol
- connection can be established via Sangoma adapter and
- a modem, over a telephone line.
-
- Thus, the WANPIPE async TTY driver simulates a serial
- TTY driver that would normally be used to interface the
- MODEM to the linux kernel.
-
- o WANPIPE PPP Backup Utility
- This utility will monitor the state of the PPP T1 line.
- In case of failure, a dial up connection will be established
- via pppd daemon, ether via a serial tty driver (serial port),
- or a WANPIPE async TTY driver (in case serial port is unavailable).
-
- Furthermore, while in dial up mode, the primary PPP T1 link
- will be monitored for signs of life.
-
- If the PPP T1 link comes back to life, the dial up connection
- will be shutdown and T1 line re-established.
-
-
- o New Setup installation script.
- Option to UPGRADE device drivers if the kernel source has
- already been patched with WANPIPE.

+Matching of PCMCIA devices to drivers is done using one or more of the
+following criteria:
+
+- manufactor ID
+- card ID
+- product ID strings _and_ hashes of these strings
+- function ID
+- device function (actual and pseudo)
+
+You should use the helpers in include/pcmcia/device_id.h for generating the
+struct pcmcia_device_id[] entries which match devices to drivers.
+
+If you want to match product ID strings, you also need to pass the crc32
+hashes of the string to the macro, e.g. if you want to match the product ID
+string 1, you need to use
+
+PCMCIA_DEVICE_PROD_ID1("some_string", 0x(hash_of_some_string)),
+
+If the hash is incorrect, the kernel will inform you about this in "dmesg"
+upon module initialization, and tell you of the correct hash.
+
+You can determine the hash of the product ID strings by catting the file
+"modalias" in the sysfs directory of the PCMCIA device. It generates a string
+in the following form:
+pcmcia:m0149cC1ABf06pfn00fn00pa725B842DpbF1EFEE84pc0877B627pd00000000
+
+The hex value after "pa" is the hash of product ID string 1, after "pb" for
+string 2 and so on.
+
+Alternatively, you can use this small tool to determine the crc32 hash.
+simply pass the string you want to evaluate as argument to this program,
+e.g.
+$ ./crc32hash "Dual Speed"
+
+-------------------------------------------------------------------------
+/* crc32hash.c - derived from linux/lib/crc32.c, GNU GPL v2 */
+#include <string.h>
+#include <stdio.h>
+#include <ctype.h>
+#include <stdlib.h>
+
+unsigned int crc32(unsigned char const *p, unsigned int len)
+{
+ int i;
+ unsigned int crc = 0;
+ while (len--) {
+ crc ^= *p++;
+ for (i = 0; i < 8; i++)
+ crc = (crc >> 1) ^ ((crc & 1) ? 0xedb88320 : 0);
+ }
+ return crc;
+}
+
+int main(int argc, char **argv) {
+ unsigned int result;
+ if (argc != 2) {
+ printf("no string passed as argument\n");
+ return -1;
+ }
+ result = crc32(argv[1], strlen(argv[1]));
+ printf("0x%x\n", result);
+ return 0;

+This file details changes in 2.6 which affect PCMCIA card driver authors:
+
+* in-kernel device<->driver matching
+ PCMCIA devices and their correct drivers can now be matched in
+ kernelspace. See 'devicetable.txt' for details.
+
+* Device model integration (as of 2.6.11)
+ A struct pcmcia_device is registered with the device model core,
+ and can be used (e.g. for SET_NETDEV_DEV) by using
+ handle_to_dev(client_handle_t * handle).
+
+* Convert internal I/O port addresses to unsigned long (as of 2.6.11)
+ ioaddr_t should be replaced by kio_addr_t in PCMCIA card drivers.
+
+* irq_mask and irq_list parameters (as of 2.6.11)
+ The irq_mask and irq_list parameters should no longer be used in
+ PCMCIA card drivers. Instead, it is the job of the PCMCIA core to
+ determine which IRQ should be used. Therefore, link->irq.IRQInfo2
+ is ignored.
+
+* client->PendingEvents is gone (as of 2.6.11)
+ client->PendingEvents is no longer available.
+
+* client->Attributes are gone (as of 2.6.11)
+ client->Attributes is unused, therefore it is removed from all
+ PCMCIA card drivers
+
+* core functions no longer available (as of 2.6.11)
+ The following functions have been removed from the kernel source
+ because they are unused by all in-kernel drivers, and no external
+ driver was reported to rely on them:
+ pcmcia_get_first_region()
+ pcmcia_get_next_region()
+ pcmcia_modify_window()
+ pcmcia_set_event_mask()
+ pcmcia_get_first_window()
+ pcmcia_get_next_window()
+
+* device list iteration upon module removal (as of 2.6.10)
+ It is no longer necessary to iterate on the driver's internal
+ client list and call the ->detach() function upon module removal.
+
+* Resource management. (as of 2.6.8)
+ Although the PCMCIA subsystem will allocate resources for cards,
+ it no longer marks these resources busy. This means that driver
+ authors are now responsible for claiming your resources as per
+ other drivers in Linux. You should use request_region() to mark
+ your IO regions in-use, and request_mem_region() to mark your
+ memory regions in-use. The name argument should be a pointer to
+ your driver name. Eg, for pcnet_cs, name should point to the
+ string "pcnet_cs".

after resume. swapoff -a; swapon -a may also be usefull.
+
+Q: What happens to devices during swsusp? They seem to be resumed
+during system suspend?
+
+A: That's correct. We need to resume them if we want to write image to
+disk. Whole sequence goes like
+
+ Suspend part

+
+ user processes are stopped
+
+ suspend(PMSG_FREEZE): devices are frozen so that they don't interfere

+ state snapshot: copy of whole used memory is taken with interrupts disabled
+

+
+ write image to swap
+
+ suspend(PMSG_SUSPEND): suspend devices so that we can power off
+
+ turn the power off
+
+ Resume part
+ ~~~~~~~~~~~
+ (is actually pretty similar)
+
+ running system, user asks for suspend-to-disk
+
+ user processes are stopped (in common case there are none, but with resume-from-initrd, noone knows)
+
+ read image from disk
+
+ suspend(PMSG_FREEZE): devices are frozen so that they don't interfere
+ with image restoration
+
+ image restoration: rewrite memory with image
+
+ resume(): devices are woken up so that system can continue
+
+ thaw all user processes
+
+Q: What is this 'Encrypt suspend image' for?
+
+A: First of all: it is not a replacement for dm-crypt encrypted swap.
+It cannot protect your computer while it is suspended. Instead it does
+protect from leaking sensitive data after resume from suspend.
+
+Think of the following: you suspend while an application is running
+that keeps sensitive data in memory. The application itself prevents
+the data from being swapped out. Suspend, however, must write these
+data to swap to be able to resume later on. Without suspend encryption
+your sensitive data are then stored in plaintext on disk. This means
+that after resume your sensitive data are accessible to all
+applications having direct access to the swap device which was used
+for suspend. If you don't need swap after resume these data can remain
+on disk virtually forever. Thus it can happen that your system gets
+broken in weeks later and sensitive data which you thought were
+encrypted and protected are retrieved and stolen from the swap device.
+To prevent this situation you should use 'Encrypt suspend image'.
+
+During suspend a temporary key is created and this key is used to
+encrypt the data written to disk. When, during resume, the data was
+read back into memory the temporary key is destroyed which simply
+means that all data written to disk during suspend are then
+inaccessible so they can't be stolen later on. The only thing that
+you must then take care of is that you call 'mkswap' for the swap
+partition used for suspend as early as possible during regular
+boot. This asserts that any temporary key from an oopsed suspend or
+from a failed or aborted resume is erased from the swap device.
+
+As a rule of thumb use encrypted swap to protect your data while your
+system is shut down or suspended. Additionally use the encrypted
+suspend image to prevent sensitive data from being stolen after
+resume.

All debug logs have an an actual debug level (range from 0 to 6).
The default level is 3. Event and Exception functions have a 'level'

writing events, high priority log entries should have a low level
value whereas low priority entries should have a high one.

Views to the debug logs can be investigated through reading the corresponding
-proc-files:
+debugfs-files:
Example:
-> ls /proc/s390dbf/dasd
-flush hex_ascii level raw
-> cat /proc/s390dbf/dasd/hex_ascii | sort +1
+> ls /sys/kernel/debug/s390dbf/dasd
+flush hex_ascii level pages raw

00 00974733272:682213 2 - 02 0006adf6 07 ea 4a 90 | ....
Example:
-> cat /proc/s390dbf/dasd/level
+> cat /sys/kernel/debug/s390dbf/dasd/level

+> echo "5" > /sys/kernel/debug/s390dbf/dasd/level
+> cat /sys/kernel/debug/s390dbf/dasd/level

Flushing debug areas
--------------------
Debug areas can be flushed with piping the number of the desired
-area (0...n) to the proc file "flush". When using "-" all debug areas
+area (0...n) to the debugfs file "flush". When using "-" all debug areas
are flushed.
Examples:
1. Flush debug area 0:
-> echo "0" > /proc/s390dbf/dasd/flush
+> echo "0" > /sys/kernel/debug/s390dbf/dasd/flush
2. Flush all debug areas:
-> echo "-" > /proc/s390dbf/dasd/flush
+> echo "-" > /sys/kernel/debug/s390dbf/dasd/flush
+
+Changing the size of debug areas
+------------------------------------
+It is possible the change the size of debug areas through piping
+the number of pages to the debugfs file "pages". The resize request will
+also flush the debug areas.
+
+Example:
+
+Define 4 pages for the debug areas of debug feature "dasd":
+> echo "4" > /sys/kernel/debug/s390dbf/dasd/pages
Stooping the debug feature
--------------------------
--------------
Views are specified with the 'debug_view' structure. There are defined
-callback functions which are used for reading and writing the proc files:
+callback functions which are used for reading and writing the debugfs files:

-<H3>Reading Images</H3>
-Each call to the <b>read</b> syscall returns the next available image
-from the device. It is up to the caller to set format and size (using
-the VIDIOCSPICT and VIDIOCSWIN ioctls) and then to pass a suitable
-size buffer and length to the function. Not all devices will support
-read operations.
-<P>
-A second way to handle image capture is via the mmap interface if supported.
-To use the mmap interface a user first sets the desired image size and depth
-properties. Next the VIDIOCGMBUF ioctl is issued. This reports the size
-of buffer to mmap and the offset within the buffer for each frame. The
-number of frames supported is device dependent and may only be one.
-<P>
-The video_mbuf structure contains the following fields
-<P>
-<TABLE>
-<TR><TD><b>size</b><TD>The number of bytes to map</TD>
-<TR><TD><b>frames</b><TD>The number of frames</TD>
-<TR><TD><b>offsets</b><TD>The offset of each frame</TD>
-</TABLE>
-<P>
-Once the mmap has been made the VIDIOCMCAPTURE ioctl starts the
-capture to a frame using the format and image size specified in the
-video_mmap (which should match or be below the initial query size).
-When the VIDIOCMCAPTURE ioctl returns the frame is <em>not</em>
-captured yet, the driver just instructed the hardware to start the
-capture. The application has to use the VIDIOCSYNC ioctl to wait
-until the capture of a frame is finished. VIDIOCSYNC takes the frame
-number you want to wait for as argument.
-<p>
-It is allowed to call VIDIOCMCAPTURE multiple times (with different
-frame numbers in video_mmap->frame of course) and thus have multiple
-outstanding capture requests. A simple way do to double-buffering
-using this feature looks like this:
-<pre>
-/* setup everything */
-VIDIOCMCAPTURE(0)
-while (whatever) {
- VIDIOCMCAPTURE(1)
- VIDIOCSYNC(0)
- /* process frame 0 while the hardware captures frame 1 */
- VIDIOCMCAPTURE(0)
- VIDIOCSYNC(1)
- /* process frame 1 while the hardware captures frame 0 */
-}
-</pre>
-Note that you are <em>not</em> limited to only two frames. The API
-allows up to 32 frames, the VIDIOCGMBUF ioctl returns the number of
-frames the driver granted. Thus it is possible to build deeper queues
-to avoid loosing frames on load peaks.
-<p>
-While capturing to memory the driver will make a "best effort" attempt
-to capture to screen as well if requested. This normally means all
-frames that "miss" memory mapped capture will go to the display.
-<P>
-A final ioctl exists to allow a device to obtain related devices if a
-driver has multiple components (for example video0 may not be associated
-with vbi0 which would cause an intercast display program to make a bad
-mistake). The VIDIOCGUNIT ioctl reports the unit numbers of the associated
-devices if any exist. The video_unit structure has the following fields.
-<P>
-<TABLE>
-<TR><TD><b>video</b><TD>Video capture device</TD>
-<TR><TD><b>vbi</b><TD>VBI capture device</TD>

-<P>
-<H3>RDS Datastreams</H3>
-For radio devices that support it, it is possible to receive Radio Data
-System (RDS) data by means of a read() on the device. The data is packed in
-groups of three, as follows:
-<TABLE>
-<TR><TD>First Octet</TD><TD>Least Significant Byte of RDS Block</TD></TR>

+The controls for the mux are GPIO [0,1] for source, and GPIO 2 for muting.
+
+GPIO0 GPIO1
+ 0 0 TV Audio
+ 1 0 FM radio
+ 0 1 Line-In
+ 1 1 Mono tuner bypass or CD passthru (tuner specific)
+
+GPIO 16(i believe) is tied to the IR port (if present).
+
+------------------------------------------------------------------------------------
+
+>From the data sheet:
+ Register 24'h20004 PCI Interrupt Status
+ bit [18] IR_SMP_INT Set when 32 input samples have been collected over
+ gpio[16] pin into GP_SAMPLE register.
+
+What's missing from the data sheet:
+
+Setup 4KHz sampling rate (roughly 2x oversampled; good enough for our RC5
+compat remote)
+set register 0x35C050 to 0xa80a80
+
+enable sampling
+set register 0x35C054 to 0x5
+
+Of course, enable the IRQ bit 18 in the interrupt mask register .(and
+provide for a handler)
+
+GP_SAMPLE register is at 0x35C058
+
+Bits are then right shifted into the GP_SAMPLE register at the specified
+rate; you get an interrupt when a full DWORD is recieved.
+You need to recover the actual RC5 bits out of the (oversampled) IR sensor
+bits. (Hint: look for the 0/1and 1/0 crossings of the RC5 bi-phase data) An
+actual raw RC5 code will span 2-3 DWORDS, depending on the actual alignment.
+
+I'm pretty sure when no IR signal is present the receiver is always in a
+marking state(1); but stray light, etc can cause intermittent noise values
+as well. Remember, this is a free running sample of the IR receiver state
+over time, so don't assume any sample starts at any particular place.

+This data sheet (google search) seems to have a lovely description of the
+RC5 basics
+
+http://users.pandora.be/nenya/electronics/rc5/ and more data
+
+http://www.ee.washington.edu/circuit_archive/text/ir_decode.txt
+and even a reference to how to decode a bi-phase data stream.

+ help
+ Select this option if you want to disable continuous timer ticks
+ and have them programmed to occur as required. This option saves
+ power as the system can remain in idle state for longer.
+
+ By default dynamic tick is disabled during the boot, and can be
+ manually enabled with:
+
+ echo 1 > /sys/devices/system/timer/timer0/dyn_tick
+
+ Alternatively, if you want dynamic tick automatically enabled
+ during boot, pass "dyntick=enable" via the kernel command string.
+
+ Please note that dynamic tick may affect the accuracy of
+ timekeeping on some platforms depending on the implementation.
+ Currently at least OMAP platform is known to have accurate
+ timekeeping with dynamic tick.

-
- 1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
- multiplies two u32 integers MULTIPLER and MULTIPLICAND,
- and generates a two-part u32 product in HIGH_PROD and
- LOW_PROD.
-
- 2) __umulsidi3(a,b) multiplies two u32 integers A and B,
- and returns a u64 product. This is just a variant of umul_ppmm.
-
- 3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
- denominator) divides a two-word unsigned integer, composed by the
- integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
- places the quotient in QUOTIENT and the remainder in REMAINDER.
- HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
- If, in addition, the most significant bit of DENOMINATOR must be 1,
- then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
-
- 4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
- denominator). Like udiv_qrnnd but the numbers are signed. The
- quotient is rounded towards 0.
-
- 5) count_leading_zeros(count, x) counts the number of zero-bits from
- the msb to the first non-zero bit. This is the number of steps X
- needs to be shifted left to set the msb. Undefined for X == 0.
-
- 6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
- high_addend_2, low_addend_2) adds two two-word unsigned integers,
- composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
- LOW_ADDEND_2 respectively. The result is placed in HIGH_SUM and
- LOW_SUM. Overflow (i.e. carry out) is not stored anywhere, and is
- lost.
-
- 7) sub_ddmmss(high_difference, low_difference, high_minuend,
- low_minuend, high_subtrahend, low_subtrahend) subtracts two
- two-word unsigned integers, composed by HIGH_MINUEND_1 and
- LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
- respectively. The result is placed in HIGH_DIFFERENCE and
- LOW_DIFFERENCE. Overflow (i.e. carry out) is not stored anywhere,
- and is lost.
-
- If any of these macros are left undefined for a particular CPU,
- C macros are used. */

+ kexec is a system call that implements the ability to shutdown your

+ but it is indepedent of the system firmware. And like a reboot
+ you can start any kernel with it, not just Linux.
+
+ The name comes from the similiarity to the exec system call.
+
+ It is an ongoing process to be certain the hardware in a machine
+ is properly shutdown, so do not be surprised if this code does not
+ initially work for you. It may help to enable device hotplugging
+ support. As of this writing the exact hardware interface is
+ strongly in flux, so no good recommendation can be made.

-config PRINTER
- tristate "Parallel printer support"
- depends on PARPORT
- ---help---
- If you intend to attach a printer to the parallel port of your Linux
- box (as opposed to using a serial printer; if the connector at the
- printer has 9 or 25 holes ["female"], then it's serial), say Y.
- Also read the Printing-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
-
- It is possible to share one parallel port among several devices
- (e.g. printer and ZIP drive) and it is safe to compile the
- corresponding drivers into the kernel. If you want to compile this
- driver as a module however, choose M here and read
- <file:Documentation/parport.txt>. The module will be called lp.
-
- If you have several parallel ports, you can specify which ports to
- use with the "lp" kernel command line option. (Try "man bootparam"
- or see the documentation of your boot loader (silo) about how to pass
- options to the kernel at boot time.) The syntax of the "lp" command
- line option can be found in <file:drivers/char/lp.c>.
-
- If you have more than 8 printers, you need to increase the LP_NO
- macro in lp.c and the PARPORT_MAX macro in parport.h.

-config PREEMPT
- bool "Preemptible Kernel"
- ---help---
- This option reduces the latency of the kernel when reacting to
- real-time or interactive events by allowing a low priority process to
- be preempted even if it is in kernel mode executing a system call.
- This allows applications to run more reliably even when the system is
- under load. On contrary it may also break your drivers and add
- priority inheritance problems to your system. Don't select it if
- you rely on a stable system or have slightly obscure hardware.
- It's also not very well tested on x86-64 currently.
- You have been warned.
-
- Say Y here if you are feeling brave and building a kernel for a
- desktop, embedded or real-time system. Say N if you are unsure.

+
+config KEXEC
+ bool "kexec system call (EXPERIMENTAL)"
+ depends on EXPERIMENTAL
+ help
+ kexec is a system call that implements the ability to shutdown your
+ current kernel, and to start another kernel. It is like a reboot
+ but it is indepedent of the system firmware. And like a reboot
+ you can start any kernel with it, not just Linux.
+
+ The name comes from the similiarity to the exec system call.
+
+ It is an ongoing process to be certain the hardware in a machine
+ is properly shutdown, so do not be surprised if this code does not
+ initially work for you. It may help to enable device hotplugging
+ support. As of this writing the exact hardware interface is
+ strongly in flux, so no good recommendation can be made.

+ *
+ * Sending broadcast introduces lots of trouble in CPU hotplug situations.

+ * Assume a memory region in ascending address:
+ * 0 1 2 3|4 5 6 7
+ *
+ * When loading one word into a register, the content of that register is:
+ * LE 3 2 1 0, 7 6 5 4
+ * BE 0 1 2 3, 4 5 6 7
+ *
+ * Masking the bits of the higher/lower address means:

+ * Double exception vector (Exceptions with PS.EXCM == 1)
+ * We get this exception when another exception occurs while were are
+ * already in an exception, such as window overflow/underflow exception,
+ * or 'expected' exceptions, for example memory exception when we were trying
+ * to read data from an invalid address in user space.
+ *
+ * Note that this vector is never invoked for level-1 interrupts, because such
+ * interrupts are disabled (masked) when PS.EXCM is set.
+ *
+ * We decode the exception and take the appropriate action. However, the
+ * double exception vector is much more careful, because a lot more error
+ * cases go through the double exception vector than through the user and
+ * kernel exception vectors.
+ *
+ * Occasionally, the kernel expects a double exception to occur. This usually
+ * happens when accessing user-space memory with the user's permissions
+ * (l32e/s32e instructions). The kernel state, though, is not always suitable
+ * for immediate transfer of control to handle_double, where "normal" exception
+ * processing occurs. Also in kernel mode, TLB misses can occur if accessing
+ * vmalloc memory, possibly requiring repair in a double exception handler.
+ *
+ * The variable at TABLE_FIXUP offset from the pointer in EXCSAVE_1 doubles as
+ * a boolean variable and a pointer to a fixup routine. If the variable
+ * EXC_TABLE_FIXUP is non-zero, this handler jumps to that address. A value of
+ * zero indicates to use the default kernel/user exception handler.
+ * There is only one exception, when the value is identical to the exc_table
+ * label, the kernel is in trouble. This mechanism is used to protect critical
+ * sections, mainly when the handler writes to the stack to assert the stack
+ * pointer is valid. Once the fixup/default handler leaves that area, the
+ * EXC_TABLE_FIXUP variable is reset to the fixup handler or zero.
+ *
+ * Procedures wishing to use this mechanism should set EXC_TABLE_FIXUP to the
+ * nonzero address of a fixup routine before it could cause a double exception
+ * and reset it before it returns.
+ *
+ * Some other things to take care of when a fast exception handler doesn't
+ * specify a particular fixup handler but wants to use the default handlers:
+ *
+ * - The original stack pointer (in a1) must not be modified. The fast
+ * exception handler should only use a2 as the stack pointer.
+ *
+ * - If the fast handler manipulates the stack pointer (in a2), it has to
+ * register a valid fixup handler and cannot use the default handlers.
+ *
+ * - The handler can use any other generic register from a3 to a15, but it
+ * must save the content of these registers to stack (PT_AREG3...PT_AREGx)
+ *
+ * - These registers must be saved before a double exception can occur.
+ *
+ * - If we ever implement handling signals while in double exceptions, the
+ * number of registers a fast handler has saved (excluding a0 and a1) must
+ * be written to PT_AREG1. (1 if only a3 is used, 2 for a3 and a4, etc. )
+ *
+ * The fixup handlers are special handlers:
+ *
+ * - Fixup entry conditions differ from regular exceptions:
+ *
+ * a0: DEPC
+ * a1: a1
+ * a2: trashed, original value in EXC_TABLE_DOUBLE_A2
+ * a3: exctable
+ * depc: a0
+ * excsave_1: a3
+ *
+ * - When the kernel enters the fixup handler, it still assumes it is in a
+ * critical section, so EXC_TABLE_FIXUP variable is set to exc_table.
+ * The fixup handler, therefore, has to re-register itself as the fixup
+ * handler before it returns from the double exception.
+ *
+ * - Fixup handler can share the same exception frame with the fast handler.
+ * The kernel stack pointer is not changed when entering the fixup handler.
+ *
+ * - Fixup handlers can jump to the default kernel and user exception
+ * handlers. Before it jumps, though, it has to setup a exception frame
+ * on stack. Because the default handler resets the register fixup handler
+ * the fixup handler must make sure that the default handler returns to
+ * it instead of the exception address, so it can re-register itself as
+ * the fixup handler.
+ *
+ * In case of a critical condition where the kernel cannot recover, we jump
+ * to unrecoverable_exception with the following entry conditions.
+ * All registers a0...a15 are unchanged from the last exception, except:
+ *
+ * a0: last address before we jumped to the unrecoverable_exception.
+ * excsave_1: a0
+ *
+ *
+ * See the handle_alloca_user and spill_registers routines for example clients.

+ * This function is intended to do the same thing as the standard

+ * However, where the source and/or destination references

+ * types of devices).

+ * !!!!!!! XTFIXME:
+ * !!!!!!! Handling of IRAM/IROM has not yet
+ * !!!!!!! been implemented.
+ *
+ * The bcopy version is provided here to avoid the overhead
+ * of an extra call, for callers that require this convention.
+ *
+ * The (general case) algorithm is as follows:
+ * If destination is unaligned, align it by conditionally
+ * copying 1 and 2 bytes.
+ * If source is aligned,
+ * do 16 bytes with a loop, and then finish up with
+ * 8, 4, 2, and 1 byte copies conditional on the length;
+ * else (if source is unaligned),
+ * do the same, but use SRC to align the source data.
+ * This code tries to use fall-through branches for the common
+ * case of aligned source and destination and multiple
+ * of 4 (or 8) length.
+ *
+ * Register use:
+ * a0/ return address
+ * a1/ stack pointer

+ *
+ * The ITE8212 isn't exactly a standard IDE controller. It has two
+ * modes. In pass through mode then it is an IDE controller. In its smart
+ * mode its actually quite a capable hardware raid controller disguised
+ * as an IDE controller. Smart mode only understands DMA read/write and
+ * identify, none of the fancier commands apply. The IT8211 is identical
+ * in other respects but lacks the raid mode.
+ *
+ * Errata:
+ * o Rev 0x10 also requires master/slave hold the same DMA timings and
+ * cannot do ATAPI MWDMA.
+ * o The identify data for raid volumes lacks CHS info (technically ok)
+ * but also fails to set the LBA28 and other bits. We fix these in
+ * the IDE probe quirk code.
+ * o If you write LBA48 sized I/O's (ie > 256 sector) in smart mode
+ * raid then the controller firmware dies
+ * o Smart mode without RAID doesn't clear all the necessary identify
+ * bits to reduce the command set to the one used
+ *
+ * This has a few impacts on the driver
+ * - In pass through mode we do all the work you would expect
+ * - In smart mode the clocking set up is done by the controller generally
+ * but we must watch the other limits and filter.
+ * - There are a few extra vendor commands that actually talk to the
+ * controller but only work PIO with no IRQ.
+ *
+ * Vendor areas of the identify block in smart mode are used for the
+ * timing and policy set up. Each HDD in raid mode also has a serial
+ * block on the disk. The hardware extra commands are get/set chip status,
+ * rebuild, get rebuild status.
+ *
+ * In Linux the driver supports pass through mode as if the device was
+ * just another IDE controller. If the smart mode is running then
+ * volumes are managed by the controller firmware and each IDE "disk"
+ * is a raid volume. Even more cute - the controller can do automated
+ * hotplug and rebuild.
+ *
+ * The pass through controller itself is a little demented. It has a
+ * flaw that it has a single set of PIO/MWDMA timings per channel so
+ * non UDMA devices restrict each others performance. It also has a
+ * single clock source per channel so mixed UDMA100/133 performance
+ * isn't perfect and we have to pick a clock. Thankfully none of this
+ * matters in smart mode. ATAPI DMA is not currently supported.
+ *
+ * It seems the smart mode is a win for RAID1/RAID10 but otherwise not.
+ *
+ * TODO
+ * - ATAPI UDMA is ok but not MWDMA it seems
+ * - RAID configuration ioctls
+ * - Move to libata once it grows up

- the frame is found, the bit stuffing is removed (0 after 5 1's).

- If the beginning of a valid frame is found, the function returns
- the length.
- If a framing error is found (too many 1s and not a flag) the function
- returns the length with the bit HDLC_FRAMING_ERROR set.
- If a CRC error is found the function returns the length with the
- bit HDLC_CRC_ERROR set.
- If the frame length exceeds the destination buffer size, the function
- returns the length with the bit HDLC_LENGTH_ERROR set.

- the Titanium Powerbook G4, as well as the iBooks. You should get
- the power management daemon, pmud, to make it work and you must have
- the /dev/pmu device (see the pmud README).
-
- Get pmud from <ftp://ftp.samba.org/pub/ppclinux/pmud/>.
-
- If you have a PowerBook, you should say Y here.
-
- You may also want to compile the dma sound driver as a module and
- have it autoloaded. The act of removing the module shuts down the
- sound hardware for more power savings.

- * FixZeroBug....Works around a bug in the SCC receving channel.
- * Taken from Darwin code, 15 Sept. 2000 -DanM
- *
- * The following sequence prevents a problem that is seen with O'Hare ASICs
- * (most versions -- also with some Heathrow and Hydra ASICs) where a zero
- * at the input to the receiver becomes 'stuck' and locks up the receiver.
- * This problem can occur as a result of a zero bit at the receiver input
- * coincident with any of the following events:
- *
- * The SCC is initialized (hardware or software).
- * A framing error is detected.
- * The clocking option changes from synchronous or X1 asynchronous
- * clocking to X16, X32, or X64 asynchronous clocking.
- * The decoding mode is changed among NRZ, NRZI, FM0, or FM1.
- *
- * This workaround attempts to recover from the lockup condition by placing
- * the SCC in synchronous loopback mode with a fast clock before programming
- * any of the asynchronous modes.

- These devices can be understood as budget ones, they "only" deliver
- (a part of) the MPEG2 transport stream.
-
- A firmware is needed to get the device working. See Documentation/dvb/README.dibusb

+ ---help---
+ Some video adapters have more than one tuner inside. This patch
+ enables support for using more than one tuner. This is required
+ for some cards to allow tunning both video and radio.
+ It also improves I2C autodetection for these cards.
+
+ Only few tuners currently is supporting this. More to come.
+
+ It is safe to say 'Y' here even if your card has only one I2C tuner.

- * o Merged fixes for v0.08 Prism 2 firmware from William Waghorn
- * <willwaghorn AT yahoo.co.uk>
- * o Slight cleanup/re-arrangement of firmware detection code.
- *
- * v0.06d -> v0.06e - 1/8/2001 - David Gibson
- * o Removed some redundant global initializers (orinoco_cs.c).
- * o Added some module metadata
- *
- * v0.06e -> v0.06f - 14/8/2001 - David Gibson
- * o Wording fix to license
- * o Added a 'use_alternate_encaps' module parameter for APs which need an
- * oui of 00:00:00. We really need a better way of handling this, but
- * the module flag is better than nothing for now.
- *
- * v0.06f -> v0.07 - 20/8/2001 - David Gibson
- * o Removed BAP error retries from hermes_bap_seek(). For Tx we now
- * let the upper layers handle the retry, we retry explicitly in the
- * Rx path, but don't make as much noise about it.
- * o Firmware detection cleanups.
- *
- * v0.07 -> v0.07a - 1/10/3001 - Jean II
- * o Add code to read Symbol firmware revision, inspired by latest code
- * in Spectrum24 by Lee John Keyser-Allen - Thanks Lee !
- * o Thanks to Jared Valentine <hidden AT xmission.com> for "providing" me
- * a 3Com card with a recent firmware, fill out Symbol firmware
- * capabilities of latest rev (2.20), as well as older Symbol cards.
- * o Disable Power Management in newer Symbol firmware, the API
- * has changed (documentation needed).
- *
- * v0.07a -> v0.08 - 3/10/2001 - David Gibson
- * o Fixed a possible buffer overrun found by the Stanford checker (in
- * dldwd_ioctl_setiwencode()). Can only be called by root anyway, so not
- * a big problem.
- * o Turned has_big_wep on for Intersil cards. That's not true for all of
- * them but we should at least let the capable ones try.
- * o Wait for BUSY to clear at the beginning of hermes_bap_seek(). I
- * realized that my assumption that the driver's serialization
- * would prevent the BAP being busy on entry was possibly false, because
- * things other than seeks may make the BAP busy.
- * o Use "alternate" (oui 00:00:00) encapsulation by default.
- * Setting use_old_encaps will mimic the old behaviour, but I think we
- * will be able to eliminate this.
- * o Don't try to make __initdata const (the version string). This can't
- * work because of the way the __initdata sectioning works.
- * o Added MODULE_LICENSE tags.
- * o Support for PLX (transparent PCMCIA->PCI bridge) cards.
- * o Changed to using the new type-fascist min/max.
- *
- * v0.08 -> v0.08a - 9/10/2001 - David Gibson
- * o Inserted some missing acknowledgements/info into the Changelog.
- * o Fixed some bugs in the normalization of signal level reporting.
- * o Fixed bad bug in WEP key handling on Intersil and Symbol firmware,
- * which led to an instant crash on big-endian machines.
- *
- * v0.08a -> v0.08b - 20/11/2001 - David Gibson
- * o Lots of cleanup and bugfixes in orinoco_plx.c
- * o Cleanup to handling of Tx rate setting.
- * o Removed support for old encapsulation method.
- * o Removed old "dldwd" names.
- * o Split RID constants into a new file hermes_rid.h
- * o Renamed RID constants to match linux-wlan-ng and prism2.o
- * o Bugfixes in hermes.c
- * o Poke the PLX's INTCSR register, so it actually starts
- * generating interrupts. These cards might actually work now.
- * o Update to wireless extensions v12 (Jean II)
- * o Support for tallies and inquire command (Jean II)
- * o Airport updates for newer PPC kernels (BenH)
- *
- * v0.08b -> v0.09 - 21/12/2001 - David Gibson
- * o Some new PCI IDs for PLX cards.
- * o Removed broken attempt to do ALLMULTI reception. Just use
- * promiscuous mode instead
- * o Preliminary work for list-AP (Jean II)
- * o Airport updates from (BenH)
- * o Eliminated racy hw_ready stuff
- * o Fixed generation of fake events in irq handler. This should
- * finally kill the EIO problems (Jean II & dgibson)
- * o Fixed breakage of bitrate set/get on Agere firmware (Jean II)
- *
- * v0.09 -> v0.09a - 2/1/2002 - David Gibson
- * o Fixed stupid mistake in multicast list handling, triggering
- * a BUG()
- *
- * v0.09a -> v0.09b - 16/1/2002 - David Gibson
- * o Fixed even stupider mistake in new interrupt handling, which
- * seriously broke things on big-endian machines.
- * o Removed a bunch of redundant includes and exports.
- * o Removed a redundant MOD_{INC,DEC}_USE_COUNT pair in airport.c
- * o Don't attempt to do hardware level multicast reception on
- * Intersil firmware, just go promisc instead.
- * o Typo fixed in hermes_issue_cmd()
- * o Eliminated WIRELESS_SPY #ifdefs
- * o Status code reported on Tx exceptions
- * o Moved netif_wake_queue() from ALLOC interrupts to TX and TXEXC
- * interrupts, which should fix the timeouts we're seeing.
- *
- * v0.09b -> v0.10 - 25 Feb 2002 - David Gibson
- * o Removed nested structures used for header parsing, so the
- * driver should now work without hackery on ARM
- * o Fix for WEP handling on Intersil (Hawk Newton)
- * o Eliminated the /proc/hermes/ethXX/regs debugging file. It
- * was never very useful.
- * o Make Rx errors less noisy.
- *
- * v0.10 -> v0.11 - 5 Apr 2002 - David Gibson
- * o Laid the groundwork in hermes.[ch] for devices which map
- * into PCI memory space rather than IO space.
- * o Fixed bug in multicast handling (cleared multicast list when
- * leaving promiscuous mode).
- * o Relegated Tx error messages to debug.
- * o Cleaned up / corrected handling of allocation lengths.
- * o Set OWNSSID in IBSS mode for WinXP interoperability (jimc).
- * o Change to using alloc_etherdev() for structure allocations.
- * o Check for and drop undersized packets.
- * o Fixed a race in stopping/waking the queue. This should fix
- * the timeout problems (Pavel Roskin)
- * o Reverted to netif_wake_queue() on the ALLOC event.
- * o Fixes for recent Symbol firmwares which lack AP density
- * (Pavel Roskin).
- *
- * v0.11 -> v0.11a - 29 Apr 2002 - David Gibson
- * o Handle different register spacing, necessary for Prism 2.5
- * PCI adaptors (Steve Hill).
- * o Cleaned up initialization of card structures in orinoco_cs
- * and airport. Removed card->priv field.
- * o Make response structure optional for hermes_docmd_wait()
- * Pavel Roskin)
- * o Added PCI id for Nortel emobility to orinoco_plx.c.
- * o Cleanup to handling of Symbol's allocation bug. (Pavel Roskin)
- * o Cleanups to firmware capability detection.
- * o Arrange for orinoco_pci.c to override firmware detection.
- * We should be able to support the PCI Intersil cards now.
- * o Cleanup handling of reset_cor and hard_reset (Pavel Roskin).
- * o Remove erroneous use of USER_BAP in the TxExc handler (Jouni
- * Malinen).
- * o Makefile changes for better integration into David Hinds
- * pcmcia-cs package.
- *
- * v0.11a -> v0.11b - 1 May 2002 - David Gibson
- * o Better error reporting in orinoco_plx_init_one()
- * o Fixed multiple bad kfree() bugs introduced by the
- * alloc_orinocodev() changes.
- *
- * v0.11b -> v0.12 - 19 Jun 2002 - David Gibson
- * o Support changing the MAC address.
- * o Correct display of Intersil firmware revision numbers.
- * o Entirely revised locking scheme. Should be both simpler and
- * better.
- * o Merged some common code in orinoco_plx, orinoco_pci and
- * airport by creating orinoco_default_{open,stop,reset}()
- * which are used as the dev->open, dev->stop, priv->reset
- * callbacks if none are specified when alloc_orinocodev() is
- * called.
- * o Removed orinoco_plx_interrupt() and orinoco_pci_interrupt().
- * They didn't do anything.
- *
- * v0.12 -> v0.12a - 4 Jul 2002 - David Gibson
- * o Some rearrangement of code.
- * o Numerous fixups to locking and rest handling, particularly
- * for PCMCIA.
- * o This allows open and stop net_device methods to be in
- * orinoco.c now, rather than in the init modules.
- * o In orinoco_cs.c link->priv now points to the struct
- * net_device not to the struct orinoco_private.
- * o Added a check for undersized SNAP frames, which could cause
- * crashes.
- *
- * v0.12a -> v0.12b - 11 Jul 2002 - David Gibson
- * o Fix hw->num_init testing code, so num_init is actually
- * incremented.
- * o Fix very stupid bug in orinoco_cs which broke compile with
- * CONFIG_SMP.
- * o Squashed a warning.
- *
- * v0.12b -> v0.12c - 26 Jul 2002 - David Gibson
- * o Change to C9X style designated initializers.
- * o Add support for 3Com AirConnect PCI.
- * o No longer ignore the hard_reset argument to
- * alloc_orinocodev(). Oops.
- *
- * v0.12c -> v0.13beta1 - 13 Sep 2002 - David Gibson
- * o Revert the broken 0.12* locking scheme and go to a new yet
- * simpler scheme.
- * o Do firmware resets only in orinoco_init() and when waking
- * the card from hard sleep.
- *
- * v0.13beta1 -> v0.13 - 27 Sep 2002 - David Gibson
- * o Re-introduced full resets (via schedule_task()) on Tx
- * timeout.
- *
- * v0.13 -> v0.13a - 30 Sep 2002 - David Gibson
- * o Minor cleanups to info frame handling. Add basic support
- * for linkstatus info frames.
- * o Include required kernel headers in orinoco.h, to avoid
- * compile problems.
- *
- * v0.13a -> v0.13b - 10 Feb 2003 - David Gibson
- * o Implemented hard reset for Airport cards
- * o Experimental suspend/resume implementation for orinoco_pci
- * o Abolished /proc debugging support, replaced with a debugging
- * iwpriv. Now it's ugly and simple instead of ugly and complex.
- * o Bugfix in hermes.c if the firmware returned a record length
- * of 0, we could go clobbering memory.
- * o Bugfix in orinoco_stop() - it used to fail if hw_unavailable
- * was set, which was usually true on PCMCIA hot removes.
- * o Track LINKSTATUS messages, silently drop Tx packets before
- * we are connected (avoids confusing the firmware), and only
- * give LINKSTATUS printk()s if the status has changed.
- *
- * v0.13b -> v0.13c - 11 Mar 2003 - David Gibson
- * o Cleanup: use dev instead of priv in various places.
- * o Bug fix: Don't ReleaseConfiguration on RESET_PHYSICAL event
- * if we're in the middle of a (driver initiated) hard reset.
- * o Bug fix: ETH_ZLEN is supposed to include the header
- * (Dionysus Blazakis & Manish Karir)
- * o Convert to using workqueues instead of taskqueues (and
- * backwards compatibility macros for pre 2.5.41 kernels).
- * o Drop redundant (I think...) MOD_{INC,DEC}_USE_COUNT in
- * airport.c
- * o New orinoco_tmd.c init module from Joerg Dorchain for
- * TMD7160 based PCI to PCMCIA bridges (similar to
- * orinoco_plx.c).
- *
- * v0.13c -> v0.13d - 22 Apr 2003 - David Gibson
- * o Make hw_unavailable a counter, rather than just a flag, this
- * is necessary to avoid some races (such as a card being
- * removed in the middle of orinoco_reset().
- * o Restore Release/RequestConfiguration in the PCMCIA event handler
- * when dealing with a driver initiated hard reset. This is
- * necessary to prevent hangs due to a spurious interrupt while
- * the reset is in progress.
- * o Clear the 802.11 header when transmitting, even though we
- * don't use it. This fixes a long standing bug on some
- * firmwares, which seem to get confused if that isn't done.
- * o Be less eager to de-encapsulate SNAP frames, only do so if
- * the OUI is 00:00:00 or 00:00:f8, leave others alone. The old
- * behaviour broke CDP (Cisco Discovery Protocol).
- * o Use dev instead of priv for free_irq() as well as
- * request_irq() (oops).
- * o Attempt to reset rather than giving up if we get too many
- * IRQs.
- * o Changed semantics of __orinoco_down() so it can be called
- * safely with hw_unavailable set. It also now clears the
- * linkstatus (since we're going to have to reassociate).
- *
- * v0.13d -> v0.13e - 12 May 2003 - David Gibson
- * o Support for post-2.5.68 return values from irq handler.
- * o Fixed bug where underlength packets would be double counted
- * in the rx_dropped statistics.
- * o Provided a module parameter to suppress linkstatus messages.
- *
- * v0.13e -> v0.14alpha1 - 30 Sep 2003 - David Gibson
- * o Replaced priv->connected logic with netif_carrier_on/off()
- * calls.
- * o Remove has_ibss_any and never set the CREATEIBSS RID when
- * the ESSID is empty. Too many firmwares break if we do.
- * o 2.6 merges: Replace pdev->slot_name with pci_name(), remove
- * __devinitdata from PCI ID tables, use free_netdev().
- * o Enabled shared-key authentication for Agere firmware (from
- * Robert J. Moore <Robert.J.Moore AT allanbank.com>
- * o Move netif_wake_queue() (back) to the Tx completion from the
- * ALLOC event. This seems to prevent/mitigate the rolling
- * error -110 problems at least on some Intersil firmwares.
- * Theoretically reduces performance, but I can't measure it.
- * Patch from Andrew Tridgell <tridge AT samba.org>
- *
- * v0.14alpha1 -> v0.14alpha2 - 20 Oct 2003 - David Gibson
- * o Correctly turn off shared-key authentication when requested
- * (bugfix from Robert J. Moore).
- * o Correct airport sleep interfaces for current 2.6 kernels.
- * o Add code for key change without disabling/enabling the MAC
- * port. This is supposed to allow 802.1x to work sanely, but
- * doesn't seem to yet.
- *
* TODO
- * o New wireless extensions API (patch from Moustafa
- * Youssef, updated by Jim Carter and Pavel Roskin).
* o Handle de-encapsulation within network layer, provide 802.11
* headers (patch from Thomas 'Dent' Mirlacher)
- * o RF monitor mode support
* o Fix possible races in SPY handling.
* o Disconnect wireless extensions from fundamental configuration.
* o (maybe) Software WEP support (patch from Stano Meduna).

- Register_client() uses the dev_info_t handle to match the

+
+ Register_client() uses the dev_info_t handle to match the

+ to a socket with bind_device() -- in fact, bind_device()
+ allocates the client structure that will be used.

+ * Encode and decode a swap entry.

+ * "present" -- valid and not swapped out, protection bits are meaningful;
+ * "not present" -- which further subdivides in these two cases:
+ * "none" -- no mapping at all; identified by pte_none(), set by pte_clear(
+ * "swapped out" -- the page is swapped out, and the SWP macros below
+ * are used to store swap file info in the PTE itself.
+ *
+ * In the Xtensa processor MMU, any PTE entries in user space (or anywhere
+ * in virtual memory that can map differently across address spaces)
+ * must have a correct ring value that represents the RASID field that
+ * is changed when switching address spaces. Eg. such PTE entries cannot
+ * be set to ring zero, because that can cause a (global) kernel ASID
+ * entry to be created in the TLBs (even with invalid cache attribute),
+ * potentially causing a multihit exception when going back to another
+ * address space that mapped the same virtual address at another ring.
+ *
+ * SO: we avoid using ring bits (_PAGE_RING_MASK) in "not present" PTEs.
+ * We also avoid using the _PAGE_VALID bit which must be zero for non-present
+ * pages.
+ *
+ * We end up with the following available bits: 1..3 and 7..31.
+ * We don't bother with 1..3 for now (we can use them later if needed),
+ * and chose to allocate 6 bits for SWP_TYPE and the remaining 19 bits
+ * for SWP_OFFSET. At least 5 bits are needed for SWP_TYPE, because it
+ * is currently implemented as an index into swap_info[MAX_SWAPFILES]
+ * and MAX_SWAPFILES is currently defined as 32 in <linux/swap.h>.
+ * However, for some reason all other architectures in the 2.4 kernel
+ * reserve either 6, 7, or 8 bits so I'll not detract from that for now. :)
+ * SWP_OFFSET is an offset into the swap file in page-size units, so
+ * with 4 kB pages, 19 bits supports a maximum swap file size of 2 GB.
+ *
+ * FIXME: 2 GB isn't very big. Other bits can be used to allow
+ * larger swap sizes. In the meantime, it appears relatively easy to get

+ * The Xtensa ABI and software conventions require the system-call
+ * number in a2. If an argument exists in a2, we move it to the next
+ * available register. Note that for improved efficiency, we do NOT
+ * shift all parameters down one register to maintain the original
+ * order.
+ *
+ * At best case (zero arguments), we just write the syscall number to
+ * a2. At worst case (1 to 6 arguments), we move the argument in a2
+ * to the next available register, then write the syscall number to
+ * a2.

+ * General notes on MMU parameters.
+ *
+ * Terminology:
+ * ASID = address-space ID (acts as an "extension" of virtual addresses)
+ * VPN = virtual page number
+ * PPN = physical page number
+ * CA = encoded cache attribute (access modes)
+ * TLB = translation look-aside buffer (term is stretched somewhat here)
+ * I = instruction (fetch accesses)
+ * D = data (load and store accesses)
+ * way = each TLB (ITLB and DTLB) consists of a number of "ways"
+ * that simultaneously match the virtual address of an access;
+ * a TLB successfully translates a virtual address if exactly
+ * one way matches the vaddr; if none match, it is a miss;
+ * if multiple match, one gets a "multihit" exception;
+ * each way can be independently configured in terms of number of
+ * entries, page sizes, which fields are writable or constant, etc.
+ * set = group of contiguous ways with exactly identical parameters
+ * ARF = auto-refill; hardware services a 1st-level miss by loading a PTE
+ * from the page table and storing it in one of the auto-refill ways;
+ * if this PTE load also misses, a miss exception is posted for s/w.
+ * min-wired = a "min-wired" way can be used to map a single (minimum-sized)
+ * page arbitrarily under program control; it has a single entry,
+ * is non-auto-refill (some other way(s) must be auto-refill),
+ * all its fields (VPN, PPN, ASID, CA) are all writable, and it
+ * supports the XCHAL_MMU_MIN_PTE_PAGE_SIZE page size (a current
+ * restriction is that this be the only page size it supports).
+ *
+ * TLB way entries are virtually indexed.
+ * TLB ways that support multiple page sizes:
+ * - must have all writable VPN and PPN fields;
+ * - can only use one page size at any given time (eg. setup at startup),
+ * selected by the respective ITLBCFG or DTLBCFG special register,
+ * whose bits n*4+3 .. n*4 index the list of page sizes for way n
+ * (XCHAL_xTLB_SETm_PAGESZ_LOG2_LIST for set m corresponding to way n);
+ * this list may be sparse for auto-refill ways because auto-refill
+ * ways have independent lists of supported page sizes sharing a
+ * common encoding with PTE entries; the encoding is the index into
+ * this list; unsupported sizes for a given way are zero in the list;
+ * selecting unsupported sizes results in undefined hardware behaviour;
+ * - is only possible for ways 0 thru 7 (due to ITLBCFG/DTLBCFG definition).

+ * floop, floopnez, floopgtz, floopend
+ *
+ * These macros are used for fast inner loops that

+ * they use explicit decrement and branch instructions.
+ *
+ * They are used in pairs, with floop, floopnez or floopgtz
+ * at the beginning of the loop, and floopend at the end.
+ *
+ * Each pair of loop macro calls must be given the loop count
+ * address register and a unique label for that loop.
+ *
+ * Example:
+ *
+ * movi a3, 16 // loop 16 times
+ * floop a3, myloop1

+ *
+ * Like the LOOP instructions, these macros cannot be

+ * cannot call functions inside the loop, etc.
+ * The loop can be exited by jumping to the instruction
+ * following floopend (or elsewhere outside the loop),
+ * or continued by jumping to a NOP instruction placed
+ * immediately before floopend.
+ *
+ * Unlike LOOP instructions, the register passed to floop*
+ * cannot be used inside the loop, because it is used as
+ * the loop counter if the Loops option is not configured.
+ * And its value is undefined after exiting the loop.
+ * And because the loop counter register is active inside
+ * the loop, you can't easily use this construct to loop
+ * across a register file using ROTW as you might with LOOP
+ * instructions, unless you copy the loop register along.

+ * .type some_function,@function

+ * entry a1, 16
+ * :

+ * window_spill4 // spill windows of some_function's callers; preserves a0..a3 only;

+ * Note: there is a distinction between the software release with
+ * which something is compiled (accessible using XTHAL_RELEASE_* macros)
+ * and the software release with which the HAL library was compiled
+ * (accessible using Xthal_release_* global variables). This
+ * distinction is particularly relevant for vendors that distribute
+ * configuration-independent binaries (eg. an OS), where their customer
+ * might link it with a HAL of a different Xtensa software release.
+ * In this case, it may be appropriate for the OS to verify at run-time
+ * whether XTHAL_RELEASE_* and Xthal_release_* are compatible.
+ * [Guidelines as to which release is compatible with which are not
+ * currently provided explicitly, but might be inferred from reading
+ * OSKit documentation for all releases -- compatibility is also highly
+ * dependent on which HAL features are used. Each release is usually
+ * backward compatible, with very few exceptions if any.]
+ *
+ * Notes:
+ * Tornado 2.0 supported in T1020.3+, T1030.1+, and T1040.{0,1} only.
+ * Tornado 2.0.2 supported in T1040.2+, and T1050.

+ * Device addresses.

+ * Note: for endianness-independence, use 32-bit loads and stores for all
+ * register accesses to Ethernet, DUART and LED devices. Undefined bits
+ * may need to be masked out if needed when reading if the actual register
+ * size is smaller than 32 bits.
+ *
+ * Note: XT2000 bus byte lanes are defined in terms of msbyte and lsbyte
+ * relative to the processor. So 32-bit registers are accessed consistently
+ * from both big and little endian processors. However, this means byte
+ * sequences are not consistent between big and little endian processors.
+ * This is fine for RAM, and for ROM if ROM is created for a specific
+ * processor (and thus has correct byte sequences). However this may be
+ * unexpected for Flash, which might contain a file-system that one wants
+ * to use for multiple processor configurations (eg. the Flash might contain
+ * the Ethernet card's address, endianness-independent application data, etc).
+ * That is, byte sequences written in Flash by a core of a given endianness
+ * will be byte-swapped when seen by a core of the other endianness.
+ * Someone implementing an endianness-independent Flash file system will
+ * likely handle this byte-swapping issue in the Flash driver software.

+ help
+ This is the traditional Linux preemption model, geared towards
+ throughput. It will still provide good latencies most of the
+ time, but there are no guarantees and occasional longer delays
+ are possible.
+
+ Select this option if you are building a kernel for a server or
+ scientific/computation system, or if you want to maximize the
+ raw processing power of the kernel, irrespective of scheduling
+ latencies.
+
+config PREEMPT_VOLUNTARY
+ bool "Voluntary Kernel Preemption (Desktop)"
+ help
+ This option reduces the latency of the kernel by adding more
+ "explicit preemption points" to the kernel code. These new
+ preemption points have been selected to reduce the maximum
+ latency of rescheduling, providing faster application reactions,
+ at the cost of slighly lower throughput.
+
+ This allows reaction to interactive events by allowing a
+ low priority process to voluntarily preempt itself even if it
+ is in kernel mode executing a system call. This allows
+ applications to run more 'smoothly' even when the system is
+ under load.
+
+ Select this if you are building a kernel for a desktop system.
+
+config PREEMPT
+ bool "Preemptible Kernel (Low-Latency Desktop)"
+ help
+ This option reduces the latency of the kernel by making
+ all kernel code (that is not executing in a critical section)
+ preemptible. This allows reaction to interactive events by
+ permitting a low priority process to be preempted involuntarily
+ even if it is in kernel mode executing a system call and would
+ otherwise not be about to reach a natural preemption point.
+ This allows applications to run more 'smoothly' even when the
+ system is under load, at the cost of slighly lower throughput
+ and a slight runtime overhead to kernel code.

+ *
+ * INTRODUCTION
+ *
+ * The textsearch infrastructure provides text searching facitilies for
+ * both linear and non-linear data. Individual search algorithms are
+ * implemented in modules and chosen by the user.
+ *
+ * ARCHITECTURE
+ *
+ * User
+ * +----------------+
+ * | finish()|<--------------(6)-----------------+
+ * |get_next_block()|<--------------(5)---------------+ |
+ * | | Algorithm | |
+ * | | +------------------------------+
+ * | | | init() find() destroy() |
+ * | | +------------------------------+
+ * | | Core API ^ ^ ^
+ * | | +---------------+ (2) (4) (8)
+ * | (1)|----->| prepare() |---+ | |
+ * | (3)|----->| find()/next() |-----------+ |
+ * | (7)|----->| destroy() |----------------------+
+ * +----------------+ +---------------+
+ *
+ * (1) User configures a search by calling _prepare() specifying the
+ * search parameters such as the pattern and algorithm name.
+ * (2) Core requests the algorithm to allocate and initialize a search
+ * configuration according to the specified parameters.
+ * (3) User starts the search(es) by calling _find() or _next() to
+ * fetch subsequent occurrences. A state variable is provided
+ * to the algorihtm to store persistant variables.
+ * (4) Core eventually resets the search offset and forwards the find()
+ * request to the algorithm.
+ * (5) Algorithm calls get_next_block() provided by the user continously
+ * to fetch the data to be searched in block by block.
+ * (6) Algorithm invokes finish() after the last call to get_next_block
+ * to clean up any leftovers from get_next_block. (Optional)
+ * (7) User destroys the configuration by calling _destroy().
+ * (8) Core notifies the algorithm to destroy algorithm specific
+ * allocations. (Optional)
+ *
+ * USAGE
+ *
+ * Before a search can be performed, a configuration must be created
+ * by calling textsearch_prepare() specyfing the searching algorithm and
+ * the pattern to look for. The returned configuration may then be used
+ * for an arbitary amount of times and even in parallel as long as a
+ * separate struct ts_state variable is provided to every instance.
+ *
+ * The actual search is performed by either calling textsearch_find_-
+ * continuous() for linear data or by providing an own get_next_block()
+ * implementation and calling textsearch_find(). Both functions return
+ * the position of the first occurrence of the patern or UINT_MAX if
+ * no match was found. Subsequent occurences can be found by calling
+ * textsearch_next() regardless of the linearity of the data.
+ *
+ * Once you're done using a configuration it must be given back via
+ * textsearch_destroy.
+ *
+ * EXAMPLE
+ *
+ * int pos;
+ * struct ts_config *conf;
+ * struct ts_state state;
+ * const char *pattern = "chicken";
+ * const char *example = "We dance the funky chicken";
+ *
+ * conf = textsearch_prepare("kmp", pattern, strlen(pattern),
+ * GFP_KERNEL, TS_AUTOLOAD);
+ * if (IS_ERR(conf)) {
+ * err = PTR_ERR(conf);
+ * goto errout;
+ * }
+ *
+ * pos = textsearch_find_continuous(conf, &state, example, strlen(example));
+ * if (pos != UINT_MAX)
+ * panic("Oh my god, dancing chickens at %d\n", pos);
+ *
+ * textsearch_destroy(conf);

+ * Implements a linear-time string-matching algorithm due to Knuth,
+ * Morris, and Pratt [1]. Their algorithm avoids the explicit
+ * computation of the transition function DELTA altogether. Its
+ * matching time is O(n), for n being length(text), using just an
+ * auxiliary function PI[1..m], for m being length(pattern),
+ * precomputed from the pattern in time O(m). The array PI allows
+ * the transition function DELTA to be computed efficiently
+ * "on the fly" as needed. Roughly speaking, for any state
+ * "q" = 0,1,...,m and any character "a" in SIGMA, the value
+ * PI["q"] contains the information that is independent of "a" and
+ * is needed to compute DELTA("q", "a") [2]. Since the array PI
+ * has only m entries, whereas DELTA has O(m|SIGMA|) entries, we
+ * save a factor of |SIGMA| in the preprocessing time by computing
+ * PI rather than DELTA.
