+Using RCU to Protect Dynamic NMI Handlers
+
+
+Although RCU is usually used to protect read-mostly data structures,
+it is possible to use RCU to provide dynamic non-maskable interrupt
+handlers, as well as dynamic irq handlers. This document describes
+how to do this, drawing loosely from Zwane Mwaikambo's NMI-timer
+work in "arch/i386/oprofile/nmi_timer_int.c" and in
+"arch/i386/kernel/traps.c".
+
+The relevant pieces of code are listed below, each followed by a
+brief explanation.
+
+ static int dummy_nmi_callback(struct pt_regs *regs, int cpu)
+ {
+ return 0;
+ }
+
+The dummy_nmi_callback() function is a "dummy" NMI handler that does
+nothing, but returns zero, thus saying that it did nothing, allowing
+the NMI handler to take the default machine-specific action.
+
+ static nmi_callback_t nmi_callback = dummy_nmi_callback;
+
+This nmi_callback variable is a global function pointer to the current
+NMI handler.
+
+ fastcall void do_nmi(struct pt_regs * regs, long error_code)
+ {
+ int cpu;
+
+ nmi_enter();
+
+ cpu = smp_processor_id();
+ ++nmi_count(cpu);
+
+ if (!rcu_dereference(nmi_callback)(regs, cpu))
+ default_do_nmi(regs);
+
+ nmi_exit();
+ }
+
+The do_nmi() function processes each NMI. It first disables preemption
+in the same way that a hardware irq would, then increments the per-CPU
+count of NMIs. It then invokes the NMI handler stored in the nmi_callback
+function pointer. If this handler returns zero, do_nmi() invokes the
+default_do_nmi() function to handle a machine-specific NMI. Finally,
+preemption is restored.
+
+Strictly speaking, rcu_dereference() is not needed, since this code runs
+only on i386, which does not need rcu_dereference() anyway. However,
+it is a good documentation aid, particularly for anyone attempting to
+do something similar on Alpha.
+
+Quick Quiz: Why might the rcu_dereference() be necessary on Alpha,
+ given that the code referenced by the pointer is read-only?
+
+
+Back to the discussion of NMI and RCU...
+
+ void set_nmi_callback(nmi_callback_t callback)
+ {
+ rcu_assign_pointer(nmi_callback, callback);
+ }
+
+The set_nmi_callback() function registers an NMI handler. Note that any
+data that is to be used by the callback must be initialized up -before-
+the call to set_nmi_callback(). On architectures that do not order
+writes, the rcu_assign_pointer() ensures that the NMI handler sees the
+initialized values.
+
+ void unset_nmi_callback(void)
+ {
+ rcu_assign_pointer(nmi_callback, dummy_nmi_callback);
+ }
+
+This function unregisters an NMI handler, restoring the original
+dummy_nmi_handler(). However, there may well be an NMI handler
+currently executing on some other CPU. We therefore cannot free
+up any data structures used by the old NMI handler until execution
+of it completes on all other CPUs.
+
+One way to accomplish this is via synchronize_sched(), perhaps as
+follows:
+
+ unset_nmi_callback();
+ synchronize_sched();
+ kfree(my_nmi_data);
+
+This works because synchronize_sched() blocks until all CPUs complete
+any preemption-disabled segments of code that they were executing.
+Since NMI handlers disable preemption, synchronize_sched() is guaranteed
+not to return until all ongoing NMI handlers exit. It is therefore safe
+to free up the handler's data as soon as synchronize_sched() returns.
+
+
+Answer to Quick Quiz
+
+ Why might the rcu_dereference() be necessary on Alpha, given
+ that the code referenced by the pointer is read-only?
+
+ Answer: The caller to set_nmi_callback() might well have
+ initialized some data that is to be used by the
+ new NMI handler. In this case, the rcu_dereference()
+ would be needed, because otherwise a CPU that received
+ an NMI just after the new handler was set might see
+ the pointer to the new NMI handler, but the old
+ pre-initialized version of the handler's data.
+
+ More important, the rcu_dereference() makes it clear
+ to someone reading the code that the pointer is being
+ protected by RCU.

+Overview
+
+The Dell Systems Management Base Driver provides a sysfs interface for
+systems management software such as Dell OpenManage to perform system
+management interrupts and host control actions (system power cycle or
+power off after OS shutdown) on certain Dell systems.
+
+Dell OpenManage requires this driver on the following Dell PowerEdge systems:
+300, 1300, 1400, 400SC, 500SC, 1500SC, 1550, 600SC, 1600SC, 650, 1655MC,
+700, and 750. Other Dell software such as the open source libsmbios project
+is expected to make use of this driver, and it may include the use of this
+driver on other Dell systems.
+
+The Dell libsmbios project aims towards providing access to as much BIOS
+information as possible. See http://linux.dell.com/libsmbios/main/ for
+more information about the libsmbios project.
+
+
+System Management Interrupt
+
+On some Dell systems, systems management software must access certain
+management information via a system management interrupt (SMI). The SMI data
+buffer must reside in 32-bit address space, and the physical address of the
+buffer is required for the SMI. The driver maintains the memory required for
+the SMI and provides a way for the application to generate the SMI.
+The driver creates the following sysfs entries for systems management
+software to perform these system management interrupts:
+
+/sys/devices/platform/dcdbas/smi_data
+/sys/devices/platform/dcdbas/smi_data_buf_phys_addr
+/sys/devices/platform/dcdbas/smi_data_buf_size
+/sys/devices/platform/dcdbas/smi_request
+
+Systems management software must perform the following steps to execute
+a SMI using this driver:
+
+1) Lock smi_data.
+2) Write system management command to smi_data.
+3) Write "1" to smi_request to generate a calling interface SMI or
+ "2" to generate a raw SMI.
+4) Read system management command response from smi_data.
+5) Unlock smi_data.
+
+
+Host Control Action
+
+Dell OpenManage supports a host control feature that allows the administrator
+to perform a power cycle or power off of the system after the OS has finished
+shutting down. On some Dell systems, this host control feature requires that
+a driver perform a SMI after the OS has finished shutting down.
+
+The driver creates the following sysfs entries for systems management software
+to schedule the driver to perform a power cycle or power off host control
+action after the system has finished shutting down:
+
+/sys/devices/platform/dcdbas/host_control_action
+/sys/devices/platform/dcdbas/host_control_smi_type
+/sys/devices/platform/dcdbas/host_control_on_shutdown
+
+Dell OpenManage performs the following steps to execute a power cycle or
+power off host control action using this driver:
+
+1) Write host control action to be performed to host_control_action.
+2) Write type of SMI that driver needs to perform to host_control_smi_type.
+3) Write "1" to host_control_on_shutdown to enable host control action.
+4) Initiate OS shutdown.
+ (Driver will perform host control SMI when it is notified that the OS
+ has finished shutting down.)
+
+
+Host Control SMI Type
+
+The following table shows the value to write to host_control_smi_type to
+perform a power cycle or power off host control action:

+Purpose:
+Demonstrate the usage of the new open sourced rbu (Remote BIOS Update) driver
+for updating BIOS images on Dell servers and desktops.
+
+Scope:
+This document discusses the functionality of the rbu driver only.
+It does not cover the support needed from aplications to enable the BIOS to
+update itself with the image downloaded in to the memory.
+
+Overview:
+This driver works with Dell OpenManage or Dell Update Packages for updating
+the BIOS on Dell servers (starting from servers sold since 1999), desktops
+and notebooks (starting from those sold in 2005).
+Please go to http://support.dell.com register and you can find info on
+OpenManage and Dell Update packages (DUP).
+
+Dell_RBU driver supports BIOS update using the monilothic image and packetized
+image methods. In case of moniolithic the driver allocates a contiguous chunk
+of physical pages having the BIOS image. In case of packetized the app
+using the driver breaks the image in to packets of fixed sizes and the driver
+would place each packet in contiguous physical memory. The driver also
+maintains a link list of packets for reading them back.
+If the dell_rbu driver is unloaded all the allocated memory is freed.
+
+The rbu driver needs to have an application which will inform the BIOS to
+enable the update in the next system reboot.
+
+The user should not unload the rbu driver after downloading the BIOS image
+or updating.
+
+The driver load creates the following directories under the /sys file system.
+/sys/class/firmware/dell_rbu/loading
+/sys/class/firmware/dell_rbu/data
+/sys/devices/platform/dell_rbu/image_type
+/sys/devices/platform/dell_rbu/data
+
+The driver supports two types of update mechanism; monolithic and packetized.
+These update mechanism depends upon the BIOS currently running on the system.
+Most of the Dell systems support a monolithic update where the BIOS image is
+copied to a single contiguous block of physical memory.
+In case of packet mechanism the single memory can be broken in smaller chuks
+of contiguous memory and the BIOS image is scattered in these packets.
+
+By default the driver uses monolithic memory for the update type. This can be
+changed to contiguous during the driver load time by specifying the load
+parameter image_type=packet. This can also be changed later as below
+echo packet > /sys/devices/platform/dell_rbu/image_type
+
+Do the steps below to download the BIOS image.
+1) echo 1 > /sys/class/firmware/dell_rbu/loading
+2) cp bios_image.hdr /sys/class/firmware/dell_rbu/data
+3) echo 0 > /sys/class/firmware/dell_rbu/loading
+
+The /sys/class/firmware/dell_rbu/ entries will remain till the following is
+done.
+echo -1 > /sys/class/firmware/dell_rbu/loading
+
+Until this step is completed the drivr cannot be unloaded.
+
+Also the driver provides /sys/devices/platform/dell_rbu/data readonly file to
+read back the image downloaded. This is useful in case of packet update
+mechanism where the above steps 1,2,3 will repeated for every packet.
+By reading the /sys/devices/platform/dell_rbu/data file all packet data
+downloaded can be verified in a single file.
+The packets are arranged in this file one after the other in a FIFO order.
+
+NOTE:
+This driver requires a patch for firmware_class.c which has the addition
+of request_firmware_nowait_nohotplug function to wortk
+Also after updating the BIOS image an user mdoe application neeeds to execute
+code which message the BIOS update request to the BIOS. So on the next reboot
+the BIOS knows about the new image downloaded and it updates it self.
+Also don't unload the rbu drive if the image has to be updated.

+
+relayfs - a high-speed data relay filesystem
+============================================
+
+relayfs is a filesystem designed to provide an efficient mechanism for
+tools and facilities to relay large and potentially sustained streams
+of data from kernel space to user space.
+
+The main abstraction of relayfs is the 'channel'. A channel consists
+of a set of per-cpu kernel buffers each represented by a file in the
+relayfs filesystem. Kernel clients write into a channel using
+efficient write functions which automatically log to the current cpu's
+channel buffer. User space applications mmap() the per-cpu files and
+retrieve the data as it becomes available.
+
+The format of the data logged into the channel buffers is completely
+up to the relayfs client; relayfs does however provide hooks which
+allow clients to impose some stucture on the buffer data. Nor does
+relayfs implement any form of data filtering - this also is left to
+the client. The purpose is to keep relayfs as simple as possible.
+
+This document provides an overview of the relayfs API. The details of
+the function parameters are documented along with the functions in the
+filesystem code - please see that for details.
+
+Semantics
+=========
+
+Each relayfs channel has one buffer per CPU, each buffer has one or
+more sub-buffers. Messages are written to the first sub-buffer until
+it is too full to contain a new message, in which case it it is
+written to the next (if available). Messages are never split across
+sub-buffers. At this point, userspace can be notified so it empties
+the first sub-buffer, while the kernel continues writing to the next.
+
+When notified that a sub-buffer is full, the kernel knows how many
+bytes of it are padding i.e. unused. Userspace can use this knowledge
+to copy only valid data.
+
+After copying it, userspace can notify the kernel that a sub-buffer
+has been consumed.
+
+relayfs can operate in a mode where it will overwrite data not yet
+collected by userspace, and not wait for it to consume it.
+
+relayfs itself does not provide for communication of such data between
+userspace and kernel, allowing the kernel side to remain simple and not
+impose a single interface on userspace. It does provide a separate
+helper though, described below.
+
+klog, relay-app & librelay
+==========================
+
+relayfs itself is ready to use, but to make things easier, two
+additional systems are provided. klog is a simple wrapper to make
+writing formatted text or raw data to a channel simpler, regardless of
+whether a channel to write into exists or not, or whether relayfs is
+compiled into the kernel or is configured as a module. relay-app is
+the kernel counterpart of userspace librelay.c, combined these two
+files provide glue to easily stream data to disk, without having to
+bother with housekeeping. klog and relay-app can be used together,
+with klog providing high-level logging functions to the kernel and
+relay-app taking care of kernel-user control and disk-logging chores.
+
+It is possible to use relayfs without relay-app & librelay, but you'll
+have to implement communication between userspace and kernel, allowing
+both to convey the state of buffers (full, empty, amount of padding).
+
+klog, relay-app and librelay can be found in the relay-apps tarball on
+http://relayfs.sourceforge.net
+
+The relayfs user space API
+==========================
+
+relayfs implements basic file operations for user space access to
+relayfs channel buffer data. Here are the file operations that are
+available and some comments regarding their behavior:
+
+open() enables user to open an _existing_ buffer.
+
+mmap() results in channel buffer being mapped into the caller's
+ memory space. Note that you can't do a partial mmap - you must
+ map the entire file, which is NRBUF * SUBBUFSIZE.
+
+read() read the contents of a channel buffer. The bytes read are
+ 'consumed' by the reader i.e. they won't be available again
+ to subsequent reads. If the channel is being used in
+ no-overwrite mode (the default), it can be read at any time
+ even if there's an active kernel writer. If the channel is
+ being used in overwrite mode and there are active channel
+ writers, results may be unpredictable - users should make
+ sure that all logging to the channel has ended before using
+ read() with overwrite mode.
+
+poll() POLLIN/POLLRDNORM/POLLERR supported. User applications are
+ notified when sub-buffer boundaries are crossed.
+
+close() decrements the channel buffer's refcount. When the refcount
+ reaches 0 i.e. when no process or kernel client has the buffer
+ open, the channel buffer is freed.
+
+
+In order for a user application to make use of relayfs files, the
+relayfs filesystem must be mounted. For example,
+
+ mount -t relayfs relayfs /mnt/relay
+
+NOTE: relayfs doesn't need to be mounted for kernel clients to create
+ or use channels - it only needs to be mounted when user space
+ applications need access to the buffer data.
+
+
+The relayfs kernel API
+======================
+
+Here's a summary of the API relayfs provides to in-kernel clients:
+
+
+ channel management functions:
+
+ relay_open(base_filename, parent, subbuf_size, n_subbufs,
+ callbacks)
+ relay_close(chan)
+ relay_flush(chan)
+ relay_reset(chan)
+ relayfs_create_dir(name, parent)
+ relayfs_remove_dir(dentry)
+
+ channel management typically called on instigation of userspace:
+
+ relay_subbufs_consumed(chan, cpu, subbufs_consumed)
+
+ write functions:
+
+ relay_write(chan, data, length)
+ __relay_write(chan, data, length)
+ relay_reserve(chan, length)
+
+ callbacks:
+
+ subbuf_start(buf, subbuf, prev_subbuf, prev_padding)
+ buf_mapped(buf, filp)
+ buf_unmapped(buf, filp)
+
+ helper functions:
+
+ relay_buf_full(buf)
+ subbuf_start_reserve(buf, length)
+
+
+Creating a channel
+------------------
+
+relay_open() is used to create a channel, along with its per-cpu
+channel buffers. Each channel buffer will have an associated file
+created for it in the relayfs filesystem, which can be opened and
+mmapped from user space if desired. The files are named
+basename0...basenameN-1 where N is the number of online cpus, and by
+default will be created in the root of the filesystem. If you want a
+directory structure to contain your relayfs files, you can create it
+with relayfs_create_dir() and pass the parent directory to
+relay_open(). Clients are responsible for cleaning up any directory
+structure they create when the channel is closed - use
+relayfs_remove_dir() for that.
+
+The total size of each per-cpu buffer is calculated by multiplying the
+number of sub-buffers by the sub-buffer size passed into relay_open().
+The idea behind sub-buffers is that they're basically an extension of
+double-buffering to N buffers, and they also allow applications to
+easily implement random-access-on-buffer-boundary schemes, which can
+be important for some high-volume applications. The number and size
+of sub-buffers is completely dependent on the application and even for
+the same application, different conditions will warrant different
+values for these parameters at different times. Typically, the right
+values to use are best decided after some experimentation; in general,
+though, it's safe to assume that having only 1 sub-buffer is a bad
+idea - you're guaranteed to either overwrite data or lose events
+depending on the channel mode being used.
+
+Channel 'modes'
+---------------
+
+relayfs channels can be used in either of two modes - 'overwrite' or
+'no-overwrite'. The mode is entirely determined by the implementation
+of the subbuf_start() callback, as described below. In 'overwrite'
+mode, also known as 'flight recorder' mode, writes continuously cycle
+around the buffer and will never fail, but will unconditionally
+overwrite old data regardless of whether it's actually been consumed.
+In no-overwrite mode, writes will fail i.e. data will be lost, if the
+number of unconsumed sub-buffers equals the total number of
+sub-buffers in the channel. It should be clear that if there is no
+consumer or if the consumer can't consume sub-buffers fast enought,
+data will be lost in either case; the only difference is whether data
+is lost from the beginning or the end of a buffer.
+
+As explained above, a relayfs channel is made of up one or more
+per-cpu channel buffers, each implemented as a circular buffer
+subdivided into one or more sub-buffers. Messages are written into
+the current sub-buffer of the channel's current per-cpu buffer via the
+write functions described below. Whenever a message can't fit into
+the current sub-buffer, because there's no room left for it, the
+client is notified via the subbuf_start() callback that a switch to a
+new sub-buffer is about to occur. The client uses this callback to 1)
+initialize the next sub-buffer if appropriate 2) finalize the previous
+sub-buffer if appropriate and 3) return a boolean value indicating
+whether or not to actually go ahead with the sub-buffer switch.
+
+To implement 'no-overwrite' mode, the userspace client would provide
+an implementation of the subbuf_start() callback something like the
+following:
+
+static int subbuf_start(struct rchan_buf *buf,
+ void *subbuf,
+ void *prev_subbuf,
+ unsigned int prev_padding)
+{
+ if (prev_subbuf)
+ *((unsigned *)prev_subbuf) = prev_padding;
+
+ if (relay_buf_full(buf))
+ return 0;
+
+ subbuf_start_reserve(buf, sizeof(unsigned int));
+
+ return 1;
+}
+
+If the current buffer is full i.e. all sub-buffers remain unconsumed,
+the callback returns 0 to indicate that the buffer switch should not
+occur yet i.e. until the consumer has had a chance to read the current
+set of ready sub-buffers. For the relay_buf_full() function to make
+sense, the consumer is reponsible for notifying relayfs when
+sub-buffers have been consumed via relay_subbufs_consumed(). Any
+subsequent attempts to write into the buffer will again invoke the
+subbuf_start() callback with the same parameters; only when the
+consumer has consumed one or more of the ready sub-buffers will
+relay_buf_full() return 0, in which case the buffer switch can
+continue.
+
+The implementation of the subbuf_start() callback for 'overwrite' mode
+would be very similar:
+
+static int subbuf_start(struct rchan_buf *buf,
+ void *subbuf,
+ void *prev_subbuf,
+ unsigned int prev_padding)
+{
+ if (prev_subbuf)
+ *((unsigned *)prev_subbuf) = prev_padding;
+
+ subbuf_start_reserve(buf, sizeof(unsigned int));
+
+ return 1;
+}
+
+In this case, the relay_buf_full() check is meaningless and the
+callback always returns 1, causing the buffer switch to occur
+unconditionally. It's also meaningless for the client to use the
+relay_subbufs_consumed() function in this mode, as it's never
+consulted.
+
+The default subbuf_start() implementation, used if the client doesn't
+define any callbacks, or doesn't define the subbuf_start() callback,
+implements the simplest possible 'no-overwrite' mode i.e. it does
+nothing but return 0.
+
+Header information can be reserved at the beginning of each sub-buffer
+by calling the subbuf_start_reserve() helper function from within the
+subbuf_start() callback. This reserved area can be used to store
+whatever information the client wants. In the example above, room is
+reserved in each sub-buffer to store the padding count for that
+sub-buffer. This is filled in for the previous sub-buffer in the
+subbuf_start() implementation; the padding value for the previous
+sub-buffer is passed into the subbuf_start() callback along with a
+pointer to the previous sub-buffer, since the padding value isn't
+known until a sub-buffer is filled. The subbuf_start() callback is
+also called for the first sub-buffer when the channel is opened, to
+give the client a chance to reserve space in it. In this case the
+previous sub-buffer pointer passed into the callback will be NULL, so
+the client should check the value of the prev_subbuf pointer before
+writing into the previous sub-buffer.
+
+Writing to a channel
+--------------------
+
+kernel clients write data into the current cpu's channel buffer using
+relay_write() or __relay_write(). relay_write() is the main logging
+function - it uses local_irqsave() to protect the buffer and should be
+used if you might be logging from interrupt context. If you know
+you'll never be logging from interrupt context, you can use
+__relay_write(), which only disables preemption. These functions
+don't return a value, so you can't determine whether or not they
+failed - the assumption is that you wouldn't want to check a return
+value in the fast logging path anyway, and that they'll always succeed
+unless the buffer is full and no-overwrite mode is being used, in
+which case you can detect a failed write in the subbuf_start()
+callback by calling the relay_buf_full() helper function.
+
+relay_reserve() is used to reserve a slot in a channel buffer which
+can be written to later. This would typically be used in applications
+that need to write directly into a channel buffer without having to
+stage data in a temporary buffer beforehand. Because the actual write
+may not happen immediately after the slot is reserved, applications
+using relay_reserve() can keep a count of the number of bytes actually
+written, either in space reserved in the sub-buffers themselves or as
+a separate array. See the 'reserve' example in the relay-apps tarball
+at http://relayfs.sourceforge.net for an example of how this can be
+done. Because the write is under control of the client and is
+separated from the reserve, relay_reserve() doesn't protect the buffer
+at all - it's up to the client to provide the appropriate
+synchronization when using relay_reserve().
+
+Closing a channel
+-----------------
+
+The client calls relay_close() when it's finished using the channel.
+The channel and its associated buffers are destroyed when there are no
+longer any references to any of the channel buffers. relay_flush()
+forces a sub-buffer switch on all the channel buffers, and can be used
+to finalize and process the last sub-buffers before the channel is
+closed.
+
+Misc
+----
+
+Some applications may want to keep a channel around and re-use it
+rather than open and close a new channel for each use. relay_reset()
+can be used for this purpose - it resets a channel to its initial
+state without reallocating channel buffer memory or destroying
+existing mappings. It should however only be called when it's safe to
+do so i.e. when the channel isn't currently being written to.
+
+Finally, there are a couple of utility callbacks that can be used for
+different purposes. buf_mapped() is called whenever a channel buffer
+is mmapped from user space and buf_unmapped() is called when it's
+unmapped. The client can use this notification to trigger actions
+within the kernel application, such as enabling/disabling logging to
+the channel.

+
+Module Parameters
+-----------------
+
+* init int
+ (default 1)
+ Use 'init=0' to bypass initializing the chip.
+ Try this if your computer crashes when you load the module.
+
+* force_subclients=bus,caddr,saddr,saddr
+ This is used to force the i2c addresses for subclients of
+ a certain chip. Example usage is `force_subclients=0,0x2f,0x4a,0x4b'
+ to force the subclients of chip 0x2f on bus 0 to i2c addresses
+ 0x4a and 0x4b.
+
+
+Description
+-----------
+
+This driver implements support for the Winbond W83792AD/D.
+
+Detection of the chip can sometimes be foiled because it can be in an
+internal state that allows no clean access (Bank with ID register is not
+currently selected). If you know the address of the chip, use a 'force'
+parameter; this will put it into a more well-behaved state first.
+
+The driver implements three temperature sensors, seven fan rotation speed
+sensors, nine voltage sensors, and two automatic fan regulation
+strategies called: Smart Fan I (Thermal Cruise mode) and Smart Fan II.
+Automatic fan control mode is possible only for fan1-fan3. Fan4-fan7 can run
+synchronized with selected fan (fan1-fan3). This functionality and manual PWM
+control for fan4-fan7 is not yet implemented.
+
+Temperatures are measured in degrees Celsius and measurement resolution is 1
+degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
+the temperature gets higher than the Overtemperature Shutdown value; it stays
+on until the temperature falls below the Hysteresis value.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64 or
+128) to give the readings more range or accuracy.
+
+Voltage sensors (also known as IN sensors) report their values in millivolts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit.
+
+Alarms are provided as output from "realtime status register". Following bits
+are defined:
+
+bit - alarm on:
+0 - in0
+1 - in1
+2 - temp1
+3 - temp2
+4 - temp3
+5 - fan1
+6 - fan2
+7 - fan3
+8 - in2
+9 - in3
+10 - in4
+11 - in5
+12 - in6
+13 - VID change
+14 - chassis
+15 - fan7
+16 - tart1
+17 - tart2
+18 - tart3
+19 - in7
+20 - in8
+21 - fan4
+22 - fan5
+23 - fan6
+
+Tart will be asserted while target temperature cannot be achieved after 3 minutes
+of full speed rotation of corresponding fan.
+
+In addition to the alarms described above, there is a CHAS alarm on the chips
+which triggers if your computer case is open (This one is latched, contrary
+to realtime alarms).
+
+The chips only update values each 3 seconds; reading them more often will
+do no harm, but will return 'old' values.
+
+
+W83792D PROBLEMS
+----------------
+Known problems:
+ - This driver is only for Winbond W83792D C version device, there
+ are also some motherboards with B version W83792D device. The
+ calculation method to in6-in7(measured value, limits) is a little
+ different between C and B version. C or B version can be identified
+ by CR[0x49h].
+ - The function of vid and vrm has not been finished, because I'm NOT
+ very familiar with them. Adding support is welcome.
+Â - The function of chassis open detection needs more tests.
+ - If you have ASUS server board and chip was not found: Then you will
+ need to upgrade to latest (or beta) BIOS. If it does not help please
+ contact us.
+
+Fan control
+-----------
+
+Manual mode
+-----------
+
+Works as expected. You just need to specify desired PWM/DC value (fan speed)
+in appropriate pwm# file.
+
+Thermal cruise
+--------------
+
+In this mode, W83792D provides the Smart Fan system to automatically control
+fan speed to keep the temperatures of CPU and the system within specific
+range. At first a wanted temperature and interval must be set. This is done
+via thermal_cruise# file. The tolerance# file serves to create T +- tolerance
+interval. The fan speed will be lowered as long as the current temperature
+remains below the thermal_cruise# +- tolerance# value. Once the temperature
+exceeds the high limit (T+tolerance), the fan will be turned on with a
+specific speed set by pwm# and automatically controlled its PWM duty cycle
+with the temperature varying. Three conditions may occur:
+
+(1) If the temperature still exceeds the high limit, PWM duty
+cycle will increase slowly.
+
+(2) If the temperature goes below the high limit, but still above the low
+limit (T-tolerance), the fan speed will be fixed at the current speed because
+the temperature is in the target range.
+
+(3) If the temperature goes below the low limit, PWM duty cycle will decrease
+slowly to 0 or a preset stop value until the temperature exceeds the low
+limit. (The preset stop value handling is not yet implemented in driver)
+
+Smart Fan II
+------------
+
+W83792D also provides a special mode for fan. Four temperature points are
+available. When related temperature sensors detects the temperature in preset
+temperature region (sf2_point@_fan# +- tolerance#) it will cause fans to run
+on programmed value from sf2_level@_fan#. You need to set four temperatures
+for each fan.
+
+
+/sys files
+----------
+
+pwm[1-3] - this file stores PWM duty cycle or DC value (fan speed) in range:
+ 0 (stop) to 255 (full)
+pwm[1-3]_enable - this file controls mode of fan/temperature control:
+ * 0 Disabled
+ * 1 Manual mode
+ * 2 Smart Fan II
+ * 3 Thermal Cruise
+pwm[1-3]_mode - Select PWM of DC mode
+ * 0 DC
+ * 1 PWM
+thermal_cruise[1-3] - Selects the desired temperature for cruise (degC)
+tolerance[1-3] - Value in degrees of Celsius (degC) for +- T
+sf2_point[1-4]_fan[1-3] - four temperature points for each fan for Smart Fan II
+sf2_level[1-3]_fan[1-3] - three PWM/DC levels for each fan for Smart Fan II

-Module Parameters
------------------
-
-* allow_write int
- Set to non-zero to enable write permission:
- *0: Read only
- 1: Read and write
-

Description
-----------
The Maxim MAX6874 is a similar, mostly compatible device, with more intputs
and outputs:
-
vin gpi vout
MAX6874 6 4 8
MAX6875 4 3 5
-MAX6874 chips can have four different addresses (as opposed to only two for
-the MAX6875). The additional addresses (0x54 and 0x56) are not probed by
-this driver by default, but the probe module parameter can be used if
-needed.
-
-See the datasheet for details on how to program the EEPROM.
+See the datasheet for more information.
Sysfs entries
-------------
-eeprom_user - 512 bytes of user-defined EEPROM space. Only writable if
- allow_write was set and register 0x43 is 0.
-
-eeprom_config - 70 bytes of config EEPROM. Note that changes will not get
- loaded into register space until a power cycle or device reset.
-
-reg_config - 70 bytes of register space. Any changes take affect immediately.
+eeprom - 512 bytes of user-defined EEPROM space.
General Remarks
---------------
-A typical application will require that the EEPROMs be programmed once and
-never altered afterwards.
+Valid addresses for the MAX6875 are 0x50 and 0x52.
+Valid addresses for the MAX6874 are 0x50, 0x52, 0x54 and 0x56.
+The driver does not probe any address, so you must force the address.
+
+Example:
+$ modprobe max6875 force=0,0x50
+
+The MAX6874/MAX6875 ignores address bit 0, so this driver attaches to multiple
+addresses. For example, for address 0x50, it also reserves 0x51.
+The even-address instance is called 'max6875', the odd one is 'max6875 subclient'.
+
+
+Programming the chip using i2c-dev
+----------------------------------
+
+Use the i2c-dev interface to access and program the chips.
+Reads and writes are performed differently depending on the address range.
+
+The configuration registers are at addresses 0x00 - 0x45.
+Use i2c_smbus_write_byte_data() to write a register and
+i2c_smbus_read_byte_data() to read a register.
+The command is the register number.
+
+Examples:
+To write a 1 to register 0x45:
+ i2c_smbus_write_byte_data(fd, 0x45, 1);
+
+To read register 0x45:
+ value = i2c_smbus_read_byte_data(fd, 0x45);
+
+
+The configuration EEPROM is at addresses 0x8000 - 0x8045.
+The user EEPROM is at addresses 0x8100 - 0x82ff.
+
+Use i2c_smbus_write_word_data() to write a byte to EEPROM.
+
+The command is the upper byte of the address: 0x80, 0x81, or 0x82.
+The data word is the lower part of the address or'd with data << 8.
+ cmd = address >> 8;
+ val = (address & 0xff) | (data << 8);
+
+Example:
+To write 0x5a to address 0x8003:
+ i2c_smbus_write_word_data(fd, 0x80, 0x5a03);
+
+
+Reading data from the EEPROM is a little more complicated.
+Use i2c_smbus_write_byte_data() to set the read address and then
+i2c_smbus_read_byte() or i2c_smbus_read_i2c_block_data() to read the data.
+
+Example:
+To read data starting at offset 0x8100, first set the address:
+ i2c_smbus_write_byte_data(fd, 0x81, 0x00);
+
+And then read the data
+ value = i2c_smbus_read_byte(fd);
+
+ or
+
+ count = i2c_smbus_read_i2c_block_data(fd, 0x84, buffer);
+
+The block read should read 16 bytes.
+0x84 is the block read command.
+
+See the datasheet for more details.
If you try to access an adapter from a userspace program, you will have
to use the /dev interface. You will still have to check whether the
functionality you need is supported, of course. This is done using

-Probing classes (i2c)
----------------------
+Probing classes
+---------------
All parameters are given as lists of unsigned 16-bit integers. Lists are
terminated by I2C_CLIENT_END.
ignore: insmod parameter.
A list of pairs. The first value is a bus number (-1 for any I2C bus),
the second is the I2C address. These addresses are never probed.
- This parameter overrules 'normal' and 'probe', but not the 'force' lists.
+ This parameter overrules the 'normal_i2c' list only.
force: insmod parameter.
A list of pairs. The first value is a bus number (-1 for any I2C bus),
the second is the I2C address. A device is blindly assumed to be on
the given address, no probing is done.
+Additionally, kind-specific force lists may optionally be defined if
+the driver supports several chip kinds. They are grouped in a
+NULL-terminated list of pointers named forces, those first element if the
+generic force list mentioned above. Each additional list correspond to an
+insmod parameter of the form force_<kind>.
+
Fortunately, as a module writer, you just have to define the `normal_i2c'
parameter. The complete declaration could look like this:
/* Magic definition of all other variables and things */
I2C_CLIENT_INSMOD;
+ /* Or, if your driver supports, say, 2 kind of devices: */
+ I2C_CLIENT_INSMOD_2(foo, bar);
+
+If you use the multi-kind form, an enum will be defined for you:
+ enum chips { any_chip, foo, bar, ... }
+You can then (and certainly should) use it in the driver code.
Note that you *have* to call the defined variable `normal_i2c',
without any prefix!
-Probing classes (sensors)
--------------------------
-
-If you write a `sensors' driver, you use a slightly different interface.
-As well as I2C addresses, we have to cope with ISA addresses. Also, we
-use a enum of chip types. Don't forget to include `sensors.h'.
-
-The following lists are used internally. They are all lists of integers.
-
- normal_i2c: filled in by the module writer. Terminated by SENSORS_I2C_END.
- A list of I2C addresses which should normally be examined.
- normal_isa: filled in by the module writer. Terminated by SENSORS_ISA_END.
- A list of ISA addresses which should normally be examined.
- probe: insmod parameter. Initialize this list with SENSORS_I2C_END values.
- A list of pairs. The first value is a bus number (SENSORS_ISA_BUS for
- the ISA bus, -1 for any I2C bus), the second is the address. These
- addresses are also probed, as if they were in the 'normal' list.
- ignore: insmod parameter. Initialize this list with SENSORS_I2C_END values.
- A list of pairs. The first value is a bus number (SENSORS_ISA_BUS for
- the ISA bus, -1 for any I2C bus), the second is the I2C address. These
- addresses are never probed. This parameter overrules 'normal' and
- 'probe', but not the 'force' lists.
-
-Also used is a list of pointers to sensors_force_data structures:
- force_data: insmod parameters. A list, ending with an element of which
- the force field is NULL.
- Each element contains the type of chip and a list of pairs.
- The first value is a bus number (SENSORS_ISA_BUS for the ISA bus,
- -1 for any I2C bus), the second is the address.
- These are automatically translated to insmod variables of the form
- force_foo.
-
-So we have a generic insmod variabled `force', and chip-specific variables
-`force_CHIPNAME'.
-
-Fortunately, as a module writer, you just have to define the `normal_i2c'
-and `normal_isa' parameters, and define what chip names are used.
-The complete declaration could look like this:
- /* Scan i2c addresses 0x37, and 0x48 to 0x4f */
- static unsigned short normal_i2c[] = { 0x37, 0x48, 0x49, 0x4a, 0x4b, 0x4c,
- 0x4d, 0x4e, 0x4f, I2C_CLIENT_END };
- /* Scan ISA address 0x290 */
- static unsigned int normal_isa[] = {0x0290,SENSORS_ISA_END};
-
- /* Define chips foo and bar, as well as all module parameters and things */
- SENSORS_INSMOD_2(foo,bar);
-
-If you have one chip, you use macro SENSORS_INSMOD_1(chip), if you have 2
-you use macro SENSORS_INSMOD_2(chip1,chip2), etc. If you do not want to
-bother with chip types, you can use SENSORS_INSMOD_0.
-
-A enum is automatically defined as follows:
- enum chips { any_chip, chip1, chip2, ... }
-
-
Attaching to an adapter
-----------------------
return i2c_probe(adapter,&addr_data,&foo_detect_client);
}
-For `sensors' drivers, use the i2c_detect function instead:
-
- int foo_attach_adapter(struct i2c_adapter *adapter)
- {
- return i2c_detect(adapter,&addr_data,&foo_detect_client);
- }
-
Remember, structure `addr_data' is defined by the macros explained above,
so you do not have to define it yourself.
-The i2c_probe or i2c_detect function will call the foo_detect_client
+The i2c_probe function will call the foo_detect_client
function only for those i2c addresses that actually have a device on
them (unless a `force' parameter was used). In addition, addresses that
are already in use (by some other registered client) are skipped.
The detect client function
--------------------------
-The detect client function is called by i2c_probe or i2c_detect.
-The `kind' parameter contains 0 if this call is due to a `force'
-parameter, and -1 otherwise (for i2c_detect, it contains 0 if
-this call is due to the generic `force' parameter, and the chip type
-number if it is due to a specific `force' parameter).
+The detect client function is called by i2c_probe. The `kind' parameter
+contains -1 for a probed detection, 0 for a forced detection, or a positive
+number for a forced detection with a chip type forced.
Below, some things are only needed if this is a `sensors' driver. Those
parts are between /* SENSORS ONLY START */ and /* SENSORS ONLY END */
markers.
-This function should only return an error (any value != 0) if there is
-some reason why no more detection should be done anymore. If the
-detection just fails for this address, return 0.
+Returning an error different from -ENODEV in a detect function will cause
+the detection to stop: other addresses and adapters won't be scanned.
+This should only be done on fatal or internal errors, such as a memory
+shortage or i2c_attach_client failing.
For now, you can ignore the `flags' parameter. It is there for future use.
const char *type_name = "";
int is_isa = i2c_is_isa_adapter(adapter);
- if (is_isa) {
+ /* Do this only if the chip can additionally be found on the ISA bus
+ (hybrid chip). */
- /* If this client can't be on the ISA bus at all, we can stop now
- (call `goto ERROR0'). But for kicks, we will assume it is all
- right. */
+ if (is_isa) {
/* Discard immediately if this ISA range is already used */
if (check_region(address,FOO_EXTENT))
/* SENSORS ONLY END */
/* Try to detach the client from i2c space */
- if ((err = i2c_detach_client(client))) {
- printk("foo.o: Client deregistration failed, client not detached.\n");
+ if ((err = i2c_detach_client(client)))
return err;
- }
- /* SENSORS ONLY START */
+ /* HYBRID SENSORS CHIP ONLY START */
if i2c_is_isa_client(client)
release_region(client->addr,LM78_EXTENT);
- /* SENSORS ONLY END */
+ /* HYBRID SENSORS CHIP ONLY END */
kfree(client); /* Frees client data too, if allocated at the same time */
return 0;

+
+===========================
+0. Introduction
+------------ ----- ----- ---- --- -- -
+
+This document provides a brief overview of the features supported by the
+IPW2100 driver project. The main project website, where the latest
+development version of the driver can be found, is:
+
+ http://ipw2100.sourceforge.net
+
+There you can find the not only the latest releases, but also information about
+potential fixes and patches, as well as links to the development mailing list
+for the driver project.
+
+
+===========================
+1. Release 1.1.0 Current Supported Features
+---------------------------
+- Managed (BSS) and Ad-Hoc (IBSS)
+- WEP (shared key and open)
+- Wireless Tools support
+- 802.1x (tested with XSupplicant 1.0.1)
+
+Enabled (but not supported) features:
+- Monitor/RFMon mode
+- WPA/WPA2
+
+The distinction between officially supported and enabled is a reflection
+on the amount of validation and interoperability testing that has been
+performed on a given feature.
+
+
+===========================
+2. Command Line Parameters
+---------------------------
+
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax:
+
+ modprobe ipw2100 [<option>=<VAL1><,VAL2>...]
+
+For example, to disable the radio on driver loading, enter:
+
+ modprobe ipw2100 disable=1
+
+The ipw2100 driver supports the following module parameters:
+
+Name Value Example:
+debug 0x0-0xffffffff debug=1024
+mode 0,1,2 mode=1 /* AdHoc */
+channel int channel=3 /* Only valid in AdHoc or Monitor */
+associate boolean associate=0 /* Do NOT auto associate */
+disable boolean disable=1 /* Do not power the HW */
+
+
+===========================
+3. Sysfs Helper Files
+---------------------------
+
+There are several ways to control the behavior of the driver. Many of the
+general capabilities are exposed through the Wireless Tools (iwconfig). There
+are a few capabilities that are exposed through entries in the Linux Sysfs.
+
+
+----- Driver Level ------
+For the driver level files, look in /sys/bus/pci/drivers/ipw2100/
+
+ debug_level
+
+ This controls the same global as the 'debug' module parameter. For
+ information on the various debugging levels available, run the 'dvals'
+ script found in the driver source directory.
+
+ NOTE: 'debug_level' is only enabled if CONFIG_IPW2100_DEBUG is turn
+ on.
+
+----- Device Level ------
+For the device level files look in
+
+ /sys/bus/pci/drivers/ipw2100/{PCI-ID}/
+
+For example:
+ /sys/bus/pci/drivers/ipw2100/0000:02:01.0
+
+For the device level files, see /sys/bus/pci/drivers/ipw2100:
+
+ rf_kill
+ read -
+ 0 = RF kill not enabled (radio on)
+ 1 = SW based RF kill active (radio off)
+ 2 = HW based RF kill active (radio off)
+ 3 = Both HW and SW RF kill active (radio off)
+ write -
+ 0 = If SW based RF kill active, turn the radio back on
+ 1 = If radio is on, activate SW based RF kill
+
+ NOTE: If you enable the SW based RF kill and then toggle the HW
+ based RF kill from ON -> OFF -> ON, the radio will NOT come back on
+
+
+===========================
+4. Radio Kill Switch
+---------------------------
+Most laptops provide the ability for the user to physically disable the radio.
+Some vendors have implemented this as a physical switch that requires no
+software to turn the radio off and on. On other laptops, however, the switch
+is controlled through a button being pressed and a software driver then making
+calls to turn the radio off and on. This is referred to as a "software based
+RF kill switch"
+
+See the Sysfs helper file 'rf_kill' for determining the state of the RF switch
+on your system.
+
+
+===========================
+5. Dynamic Firmware
+---------------------------
+As the firmware is licensed under a restricted use license, it can not be
+included within the kernel sources. To enable the IPW2100 you will need a
+firmware image to load into the wireless NIC's processors.
+
+You can obtain these images from <http://ipw2100.sf.net/firmware.php>.
+
+See INSTALL for instructions on installing the firmware.
+
+
+===========================
+6. Power Management
+---------------------------
+The IPW2100 supports the configuration of the Power Save Protocol
+through a private wireless extension interface. The IPW2100 supports
+the following different modes:
+
+ off No power management. Radio is always on.
+ on Automatic power management
+ 1-5 Different levels of power management. The higher the
+ number the greater the power savings, but with an impact to
+ packet latencies.
+
+Power management works by powering down the radio after a certain
+interval of time has passed where no packets are passed through the
+radio. Once powered down, the radio remains in that state for a given
+period of time. For higher power savings, the interval between last
+packet processed to sleep is shorter and the sleep period is longer.
+
+When the radio is asleep, the access point sending data to the station
+must buffer packets at the AP until the station wakes up and requests
+any buffered packets. If you have an AP that does not correctly support
+the PSP protocol you may experience packet loss or very poor performance
+while power management is enabled. If this is the case, you will need
+to try and find a firmware update for your AP, or disable power
+management (via `iwconfig eth1 power off`)
+
+To configure the power level on the IPW2100 you use a combination of
+iwconfig and iwpriv. iwconfig is used to turn power management on, off,
+and set it to auto.
+
+ iwconfig eth1 power off Disables radio power down
+ iwconfig eth1 power on Enables radio power management to
+ last set level (defaults to AUTO)
+ iwpriv eth1 set_power 0 Sets power level to AUTO and enables
+ power management if not previously
+ enabled.
+ iwpriv eth1 set_power 1-5 Set the power level as specified,
+ enabling power management if not
+ previously enabled.
+
+You can view the current power level setting via:
+
+ iwpriv eth1 get_power
+
+It will return the current period or timeout that is configured as a string
+in the form of xxxx/yyyy (z) where xxxx is the timeout interval (amount of
+time after packet processing), yyyy is the period to sleep (amount of time to
+wait before powering the radio and querying the access point for buffered
+packets), and z is the 'power level'. If power management is turned off the
+xxxx/yyyy will be replaced with 'off' -- the level reported will be the active
+level if `iwconfig eth1 power on` is invoked.

+
+1. Introduction
+-----------------------------------------------
+The following sections attempt to provide a brief introduction to using
+the Intel(R) PRO/Wireless 2915ABG Driver for Linux.
+
+This document is not meant to be a comprehensive manual on
+understanding or using wireless technologies, but should be sufficient
+to get you moving without wires on Linux.
+
+For information on building and installing the driver, see the INSTALL
+file.
+
+
+1.1. Overview of Features
+-----------------------------------------------
+The current release (1.0.0) supports the following features:
+
++ BSS mode (Infrastructure, Managed)
++ IBSS mode (Ad-Hoc)
++ WEP (OPEN and SHARED KEY mode)
++ 802.1x EAP via wpa_supplicant and xsupplicant
++ Wireless Extension support
++ Full B and G rate support (2200 and 2915)
++ Full A rate support (2915 only)
++ Transmit power control
++ S state support (ACPI suspend/resume)
++ long/short preamble support
+
+
+
+1.2. Command Line Parameters
+-----------------------------------------------
+
+Like many modules used in the Linux kernel, the Intel(R) PRO/Wireless
+2915ABG Driver for Linux allows certain configuration options to be
+provided as module parameters. The most common way to specify a module
+parameter is via the command line.
+
+The general form is:
+
+% modprobe ipw2200 parameter=value
+
+Where the supported parameter are:
+
+ associate
+ Set to 0 to disable the auto scan-and-associate functionality of the
+ driver. If disabled, the driver will not attempt to scan
+ for and associate to a network until it has been configured with
+ one or more properties for the target network, for example configuring
+ the network SSID. Default is 1 (auto-associate)
+
+ Example: % modprobe ipw2200 associate=0
+
+ auto_create
+ Set to 0 to disable the auto creation of an Ad-Hoc network
+ matching the channel and network name parameters provided.
+ Default is 1.
+
+ channel
+ channel number for association. The normal method for setting
+ the channel would be to use the standard wireless tools
+ (i.e. `iwconfig eth1 channel 10`), but it is useful sometimes
+ to set this while debugging. Channel 0 means 'ANY'
+
+ debug
+ If using a debug build, this is used to control the amount of debug
+ info is logged. See the 'dval' and 'load' script for more info on
+ how to use this (the dval and load scripts are provided as part
+ of the ipw2200 development snapshot releases available from the
+ SourceForge project at http://ipw2200.sf.net)
+
+ mode
+ Can be used to set the default mode of the adapter.
+ 0 = Managed, 1 = Ad-Hoc
+
+
+1.3. Wireless Extension Private Methods
+-----------------------------------------------
+
+As an interface designed to handle generic hardware, there are certain
+capabilities not exposed through the normal Wireless Tool interface. As
+such, a provision is provided for a driver to declare custom, or
+private, methods. The Intel(R) PRO/Wireless 2915ABG Driver for Linux
+defines several of these to configure various settings.
+
+The general form of using the private wireless methods is:
+
+ % iwpriv $IFNAME method parameters
+
+Where $IFNAME is the interface name the device is registered with
+(typically eth1, customized via one of the various network interface
+name managers, such as ifrename)
+
+The supported private methods are:
+
+ get_mode
+ Can be used to report out which IEEE mode the driver is
+ configured to support. Example:
+
+ % iwpriv eth1 get_mode
+ eth1 get_mode:802.11bg (6)
+
+ set_mode
+ Can be used to configure which IEEE mode the driver will
+ support.
+
+ Usage:
+ % iwpriv eth1 set_mode {mode}
+ Where {mode} is a number in the range 1-7:
+ 1 802.11a (2915 only)
+ 2 802.11b
+ 3 802.11ab (2915 only)
+ 4 802.11g
+ 5 802.11ag (2915 only)
+ 6 802.11bg
+ 7 802.11abg (2915 only)
+
+ get_preamble
+ Can be used to report configuration of preamble length.
+
+ set_preamble
+ Can be used to set the configuration of preamble length:
+
+ Usage:
+ % iwpriv eth1 set_preamble {mode}
+ Where {mode} is one of:
+ 1 Long preamble only
+ 0 Auto (long or short based on connection)
+
+
+1.4. Sysfs Helper Files:
+-----------------------------------------------
+
+The Linux kernel provides a pseudo file system that can be used to
+access various components of the operating system. The Intel(R)
+PRO/Wireless 2915ABG Driver for Linux exposes several configuration
+parameters through this mechanism.
+
+An entry in the sysfs can support reading and/or writing. You can
+typically query the contents of a sysfs entry through the use of cat,
+and can set the contents via echo. For example:
+
+% cat /sys/bus/pci/drivers/ipw2200/debug_level
+
+Will report the current debug level of the driver's logging subsystem
+(only available if CONFIG_IPW_DEBUG was configured when the driver was
+built).
+
+You can set the debug level via:
+
+% echo $VALUE > /sys/bus/pci/drivers/ipw2200/debug_level
+
+Where $VALUE would be a number in the case of this sysfs entry. The
+input to sysfs files does not have to be a number. For example, the
+firmware loader used by hotplug utilizes sysfs entries for transferring
+the firmware image from user space into the driver.
+
+The Intel(R) PRO/Wireless 2915ABG Driver for Linux exposes sysfs entries
+at two levels -- driver level, which apply to all instances of the
+driver (in the event that there are more than one device installed) and
+device level, which applies only to the single specific instance.
+
+
+1.4.1 Driver Level Sysfs Helper Files
+-----------------------------------------------
+
+For the driver level files, look in /sys/bus/pci/drivers/ipw2200/
+
+ debug_level
+
+ This controls the same global as the 'debug' module parameter
+
+
+1.4.2 Device Level Sysfs Helper Files
+-----------------------------------------------
+
+For the device level files, look in
+
+ /sys/bus/pci/drivers/ipw2200/{PCI-ID}/
+
+For example:
+ /sys/bus/pci/drivers/ipw2200/0000:02:01.0
+
+For the device level files, see /sys/bus/pci/[drivers/ipw2200:
+
+ rf_kill
+ read -
+ 0 = RF kill not enabled (radio on)
+ 1 = SW based RF kill active (radio off)
+ 2 = HW based RF kill active (radio off)
+ 3 = Both HW and SW RF kill active (radio off)
+ write -
+ 0 = If SW based RF kill active, turn the radio back on
+ 1 = If radio is on, activate SW based RF kill
+
+ NOTE: If you enable the SW based RF kill and then toggle the HW
+ based RF kill from ON -> OFF -> ON, the radio will NOT come back on
+
+ ucode
+ read-only access to the ucode version number
+
+
+2. About the Version Numbers
+-----------------------------------------------
+
+Due to the nature of open source development projects, there are
+frequently changes being incorporated that have not gone through
+a complete validation process. These changes are incorporated into
+development snapshot releases.
+
+Releases are numbered with a three level scheme:
+
+ major.minor.development
+
+Any version where the 'development' portion is 0 (for example
+1.0.0, 1.1.0, etc.) indicates a stable version that will be made
+available for kernel inclusion.
+
+Any version where the 'development' portion is not a 0 (for
+example 1.0.1, 1.1.5, etc.) indicates a development version that is
+being made available for testing and cutting edge users. The stability
+and functionality of the development releases are not know. We make
+efforts to try and keep all snapshots reasonably stable, but due to the
+frequency of their release, and the desire to get those releases
+available as quickly as possible, unknown anomalies should be expected.
+
+The major version number will be incremented when significant changes
+are made to the driver. Currently, there are no major changes planned.
+
+

+How to use dm-crypt and swsusp together:
+========================================
+
+Some prerequisites:
+You know how dm-crypt works. If not, visit the following web page:
+http://www.saout.de/misc/dm-crypt/
+You have read Documentation/power/swsusp.txt and understand it.
+You did read Documentation/initrd.txt and know how an initrd works.
+You know how to create or how to modify an initrd.
+
+Now your system is properly set up, your disk is encrypted except for
+the swap device(s) and the boot partition which may contain a mini
+system for crypto setup and/or rescue purposes. You may even have
+an initrd that does your current crypto setup already.
+
+At this point you want to encrypt your swap, too. Still you want to
+be able to suspend using swsusp. This, however, means that you
+have to be able to either enter a passphrase or that you read
+the key(s) from an external device like a pcmcia flash disk
+or an usb stick prior to resume. So you need an initrd, that sets
+up dm-crypt and then asks swsusp to resume from the encrypted
+swap device.
+
+The most important thing is that you set up dm-crypt in such
+a way that the swap device you suspend to/resume from has
+always the same major/minor within the initrd as well as
+within your running system. The easiest way to achieve this is
+to always set up this swap device first with dmsetup, so that
+it will always look like the following:
+
+brw------- 1 root root 254, 0 Jul 28 13:37 /dev/mapper/swap0
+
+Now set up your kernel to use /dev/mapper/swap0 as the default
+resume partition, so your kernel .config contains:
+
+CONFIG_PM_STD_PARTITION="/dev/mapper/swap0"
+
+Prepare your boot loader to use the initrd you will create or
+modify. For lilo the simplest setup looks like the following
+lines:
+
+image=/boot/vmlinuz
+initrd=/boot/initrd.gz
+label=linux
+append="root=/dev/ram0 init=/linuxrc rw"
+
+Finally you need to create or modify your initrd. Lets assume
+you create an initrd that reads the required dm-crypt setup
+from a pcmcia flash disk card. The card is formatted with an ext2
+fs which resides on /dev/hde1 when the card is inserted. The
+card contains at least the encrypted swap setup in a file
+named "swapkey". /etc/fstab of your initrd contains something
+like the following:
+
+/dev/hda1 /mnt ext3 ro 0 0
+none /proc proc defaults,noatime,nodiratime 0 0
+none /sys sysfs defaults,noatime,nodiratime 0 0
+
+/dev/hda1 contains an unencrypted mini system that sets up all
+of your crypto devices, again by reading the setup from the
+pcmcia flash disk. What follows now is a /linuxrc for your
+initrd that allows you to resume from encrypted swap and that
+continues boot with your mini system on /dev/hda1 if resume
+does not happen:
+
+#!/bin/sh
+PATH=/sbin:/bin:/usr/sbin:/usr/bin
+mount /proc
+mount /sys
+mapped=0
+noresume=`grep -c noresume /proc/cmdline`
+if [ "$*" != "" ]
+then
+ noresume=1
+fi
+dmesg -n 1
+/sbin/cardmgr -q
+for i in 1 2 3 4 5 6 7 8 9 0
+do
+ if [ -f /proc/ide/hde/media ]
+ then
+ usleep 500000
+ mount -t ext2 -o ro /dev/hde1 /mnt
+ if [ -f /mnt/swapkey ]
+ then
+ dmsetup create swap0 /mnt/swapkey > /dev/null 2>&1 && mapped=1
+ fi
+ umount /mnt
+ break
+ fi
+ usleep 500000
+done
+killproc /sbin/cardmgr
+dmesg -n 6
+if [ $mapped = 1 ]
+then
+ if [ $noresume != 0 ]
+ then
+ mkswap /dev/mapper/swap0 > /dev/null 2>&1
+ fi
+ echo 254:0 > /sys/power/resume
+ dmsetup remove swap0
+fi
+umount /sys
+mount /mnt
+umount /proc
+cd /mnt
+pivot_root . mnt
+mount /proc
+umount -l /mnt
+umount /proc
+exec chroot . /sbin/init $* < dev/console > dev/console 2>&1
+
+Please don't mind the weird loop above, busybox's msh doesn't know
+the let statement. Now, what is happening in the script?
+First we have to decide if we want to try to resume, or not.
+We will not resume if booting with "noresume" or any parameters
+for init like "single" or "emergency" as boot parameters.
+
+Then we need to set up dmcrypt with the setup data from the
+pcmcia flash disk. If this succeeds we need to reset the swap
+device if we don't want to resume. The line "echo 254:0 > /sys/power/resume"
+then attempts to resume from the first device mapper device.
+Note that it is important to set the device in /sys/power/resume,
+regardless if resuming or not, otherwise later suspend will fail.
+If resume starts, script execution terminates here.
+
+Otherwise we just remove the encrypted swap device and leave it to the
+mini system on /dev/hda1 to set the whole crypto up (it is up to
+you to modify this to your taste).
+
+What then follows is the well known process to change the root
+file system and continue booting from there. I prefer to unmount
+the initrd prior to continue booting but it is up to you to modify
+this.
-From kernel/suspend.c:
+Some warnings, first.
* BIG FAT WARNING *********************************************************
*
- * If you have unsupported (*) devices using DMA...
- * ...say goodbye to your data.
- *
* If you touch anything on disk between suspend and resume...
* ...kiss your data goodbye.
*
- * If your disk driver does not support suspend... (IDE does)
- * ...you'd better find out how to get along
- * without your data.
- *
- * If you change kernel command line between suspend and resume...
- * ...prepare for nasty fsck or worse.
+ * If you do resume from initrd after your filesystems are mounted...
+ * ...bye bye root partition.
+ * [this is actually same case as above]
*
- * If you change your hardware while system is suspended...
- * ...well, it was not good idea.
+ * If you have unsupported (*) devices using DMA, you may have some
+ * problems. If your disk driver does not support suspend... (IDE does),
+ * it may cause some problems, too. If you change kernel command line
+ * between suspend and resume, it may do something wrong. If you change
+ * your hardware while system is suspended... well, it was not good idea;
+ * but it will probably only crash.
*
* (*) suspend/resume support is needed to make it safe.

+Encrypted suspend image:
+------------------------
+If you want to store your suspend image encrypted with a temporary
+key to prevent data gathering after resume you must compile
+crypto and the aes algorithm into the kernel - modules won't work
+as they cannot be loaded at resume time.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You have your server on UPS. Power died, and UPS is indicating 30
seconds to failure. What do you do? Suspend to disk.
-Ethernet card in your server died. You want to replace it. Your
-server is not hotplug capable. What do you do? Suspend to disk,
-replace ethernet card, resume. If you are fast your users will not
-even see broken connections.
-
Q: Maybe I'm missing something, but why don't the regular I/O paths work?
A: Yes. That's what echo platform > /sys/power/disk does.
-Q: My machine doesn't work with ACPI. How can I use swsusp than ?
-
-A: Do a reboot() syscall with right parameters. Warning: glibc gets in
-its way, so check with strace:
-
-reboot(LINUX_REBOOT_MAGIC1, LINUX_REBOOT_MAGIC2, 0xd000fce2)
-
-(Thanks to Peter Osterlund:)

-#include <syscall.h>

Q: What is 'suspend2'?
A: suspend2 is 'Software Suspend 2', a forked implementation of
system is shut down or suspended. Additionally use the encrypted
suspend image to prevent sensitive data from being stolen after
resume.
+
+Q: Why can't we suspend to a swap file?
+
+A: Because accessing swap file needs the filesystem mounted, and
+filesystem might do something wrong (like replaying the journal)
+during mount.
+
+There are few ways to get that fixed:
+
+1) Probably could be solved by modifying every filesystem to support
+some kind of "really read-only!" option. Patches welcome.
+
+2) suspend2 gets around that by storing absolute positions in on-disk
+image (and blocksize), with resume parameter pointing directly to
+suspend header.
+
+Q: Is there a maximum system RAM size that is supported by swsusp?
+
+A: It should work okay with highmem.
+
+Q: Does swsusp (to disk) use only one swap partition or can it use
+multiple swap partitions (aggregate them into one logical space)?
+
+A: Only one swap partition, sorry.
+
+Q: If my application(s) causes lots of memory & swap space to be used
+(over half of the total system RAM), is it correct that it is likely
+to be useless to try to suspend to disk while that app is running?
+
+A: No, it should work okay, as long as your app does not mlock()
+it. Just prepare big enough swap partition.
+
+Q: What information is usefull for debugging suspend-to-disk problems?
+
+A: Well, last messages on the screen are always useful. If something
+is broken, it is usually some kernel driver, therefore trying with as
+little as possible modules loaded helps a lot. I also prefer people to
+suspend from console, preferably without X running. Booting with
+init=/bin/bash, then swapon and starting suspend sequence manually
+usually does the trick. Then it is good idea to try with latest
+vanilla kernel.

POSTing bios works. Ole Rohne has patch to do just that at
http://dev.gentoo.org/~marineam/patch-radeonfb-2.6.11-rc2-mm2.
+(8) on some systems, you can use the video_post utility mentioned here:
+ http://bugzilla.kernel.org/show_bug.cgi?id=3670. Do echo 3 > /sys/power/state
+ && /usr/sbin/video_post - which will initialize the display in console mode.
+ If you are in X, you can switch to a virtual terminal and back to X using
+ CTRL+ALT+F1 - CTRL+ALT+F7 to get the display working in graphical mode again.

Now, if you pass acpi_sleep=something, and it does not work with your
bios, you'll get a hard crash during resume. Be careful. Also it is

- * The three PCI devices on the motherboard have dedicated lines to the

- * staggered INTA-D lines, resulting in 8 lines total (PCI0 INTA-D and
- * PCI1 INTA-D). All 8 go to the CPLD interrupt controller. PCI0 INTA-D
- * also go to the south bridge, so we have the option of taking them
- * via the CPLD interrupt controller or via the south bridge 8259
- * 8258 thingy. PCI1 INTA-D can only be taken via the CPLD interrupt
- * controller. We take all PCI interrupts via the CPLD interrupt
- * controller as recommended by SBS.
- *
- * We also have some monkey business with the PCI devices within the
- * VT82C686B south bridge itself. This chip actually has 7 functions on
- * its IDSEL. Function 0 is the actual south bridge, function 1 is IDE,
- * and function 4 is some special stuff. The other 4 functions are just
- * regular PCI devices bundled in the chip. 2 and 3 are USB UHCIs and 5
- * and 6 are audio (not supported on the Adirondack).
- *
- * This is where the monkey business begins. PCI devices are supposed
- * to signal normal PCI interrupts. But the 4 functions in question are
- * located in the south bridge chip, which is designed with the
- * assumption that it will be fielding PCI INTA-D interrupts rather
- * than generating them. Here's what it does. Each of the functions in
- * question routes its interrupt to one of the IRQs on the 8259 thingy.
- * Which one? It looks at the Interrupt Line register in the PCI config
- * space, even though the PCI spec says it's for BIOS/OS interaction
- * only.
- *
- * How do we deal with this? We take these interrupts via 8259 IRQs as
- * we have to. We return the desired IRQ numbers from this routine when
- * called for the functions in question. The PCI scan code will then
- * stick our return value into the Interrupt Line register in the PCI
- * config space, and the interrupt will actually go there. We identify
- * these functions within the south bridge IDSEL by their interrupt pin
- * numbers, as the VT82C686B has 04 in the Interrupt Pin register for
- * USB and 03 for audio.

-config VT

- default y
- ---help---
- If you say Y here, you will get support for terminal devices with
- display and keyboard devices. These are called "virtual" because you
- can run several virtual terminals (also called virtual consoles) on
- one physical terminal. This is rather useful, for example one
- virtual terminal can collect system messages and warnings, another
- one can be used for a text-mode user session, and a third could run
- an X session, all in parallel. Switching between virtual terminals
- is done with certain key combinations, usually Alt-<function key>.
-
- The setterm command ("man setterm") can be used to change the
- properties (such as colors or beeping) of a virtual terminal. The
- man page console_codes(4) ("man console_codes") contains the special
- character sequences that can be used to change those properties
- directly. The fonts used on virtual terminals can be changed with
- the setfont ("man setfont") command and the key bindings are defined
- with the loadkeys ("man loadkeys") command.
-
- You need at least one virtual terminal device in order to make use
- of your keyboard and monitor. Therefore, only people configuring an
- embedded system would want to say N here in order to save some
- memory; the only way to log into such a system is then via a serial
- or network connection.
-

- answer Y here, a virtual terminal (the device used to interact with
- a physical terminal) can be used as system console. This is the most
- common mode of operations, so you should say Y here unless you want
- the kernel messages be output only to a serial port (in which case
- you should say Y to "Console on serial port", below).
-
- If you do say Y here, by default the currently visible virtual
- terminal (/dev/tty0) will be used as system console. You can change
- that with a kernel command line option such as "console=tty3" which
- would use the third virtual terminal as system console. (Try "man

-config UNIX98_PTYS
- bool "Unix98 PTY support"
- ---help---
- A pseudo terminal (PTY) is a software device consisting of two
- halves: a master and a slave. The slave device behaves identical to
- a physical terminal; the master device is used by a process to
- read data from and write data to the slave, thereby emulating a
- terminal. Typical programs for the master side are telnet servers
- and xterms.
-
- Linux has traditionally used the BSD-like names /dev/ptyxx for
- masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
- has a number of problems. The GNU C library glibc 2.1 and later,
- however, supports the Unix98 naming standard: in order to acquire a
- pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
- terminal is then made available to the process and the pseudo
- terminal slave can be accessed as /dev/pts/<number>. What was
- traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
-
- The entries in /dev/pts/ are created on the fly by a virtual
- file system; therefore, if you say Y here you should say Y to
- "/dev/pts file system for Unix98 PTYs" as well.
-
- If you want to say Y here, you need to have the C library glibc 2.1
- or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
- Read the instructions in <file:Documentation/Changes> pertaining to
- pseudo terminals. It's safe to say N.

- machines which support incoming telnet/rlogin/ssh connections and/or
- serve several X terminals may want to increase this: every incoming
- connection and every xterm uses up one PTY.

+ known as SLiRP, a program that can re-socket IP packets back onto
+ the host on which it is run. Only IP packets are supported,
+ unlike other network transports that can handle all Ethernet
+ frames. In general, slirp allows the UML the same IP connectivity
+ to the outside world that the host user is permitted, and unlike
+ other transports, SLiRP works without the need of root level
+ privleges, setuid binaries, or SLIP devices on the host. This
+ also means not every type of connection is possible, but most
+ situations can be accomodated with carefully crafted slirp
+ commands that can be passed along as part of the network device's
+ setup string. The effect of this transport on the UML is similar
+ that of a host behind a firewall that masquerades all network
+ connections passing through it (but is less secure).

- terminal is then made available to the process and the pseudo
- terminal slave can be accessed as /dev/pts/<number>. What was
- traditionally /dev/ttyp2 will then be /dev/pts/2, for example.

-config LEGACY_PTYS
- bool "Legacy (BSD) PTY support"

- ---help---
- A pseudo terminal (PTY) is a software device consisting of two
- halves: a master and a slave. The slave device behaves identical to
- a physical terminal; the master device is used by a process to
- read data from and write data to the slave, thereby emulating a
- terminal. Typical programs for the master side are telnet servers
- and xterms.
-
- Linux has traditionally used the BSD-like names /dev/ptyxx
- for masters and /dev/ttyxx for slaves of pseudo
- terminals. This scheme has a number of problems, including
- security. This option enables these legacy devices; on most
- systems, it is safe to say N.

- The Ethertap User-Mode Linux network transport allows a single
- running UML to exchange packets with its host over one of the
- host's Ethertap devices, such as /dev/tap0. Additional running
- UMLs can use additional Ethertap devices, one per running UML.
- While the UML believes it's on a (multi-device, broadcast) virtual
- Ethernet network, it's in fact communicating over a point-to-point
- link with the host.
-
- To use this, your host kernel must have support for Ethertap
- devices. Also, if your host kernel is 2.4.x, it must have
- CONFIG_NETLINK_DEV configured as Y or M.
-
- For more information, see
- <http://user-mode-linux.sourceforge.net/networking.html> That site
- has examples of the UML command line to use to enable Ethertap
- networking.
-
- If you'd like to set up an IP network with the host and/or the

- Slip Transport. You'll need at least one of them, but may choose
- more than one without conflict. If you don't need UML networking,

- devices, either built-in or as a module.
-
-config UML_NET_SLIP

- depends on UML_NET
- help
- The slip User-Mode Linux network transport allows a running UML to
- network with its host over a point-to-point link. Unlike Ethertap,
- which can carry any Ethernet frame (and hence even non-IP packets),
- the slip transport can only carry IP packets.
-
- To use this, your host must support slip devices.
-
- For more information, see
- <http://user-mode-linux.sourceforge.net/networking.html>. That site
- has examples of the UML command line to use to enable slip
- networking, and details of a few quirks with it.
-
- The Ethertap Transport is preferred over slip because of its
- limitations. If you prefer slip, however, say Y here. Otherwise
- choose the Multicast transport (to network multiple UMLs on
- multiple hosts), Ethertap (to network with the host and the
- outside world), and/or the Daemon transport (to network multiple
- UMLs on a single host). You may choose more than one without
- conflict. If you don't need UML networking, say N.

- bool "Multicast transport"

- help
- This Multicast User-Mode Linux network transport allows multiple

- each other over a virtual ethernet network. However, it requires
- at least one UML with one of the other transports to act as a
- bridge if any of them need to be able to talk to their hosts or any
- other IP machines.
-
- To use this, your host kernel(s) must support IP Multicasting.
-
- For more information, see
- <http://user-mode-linux.sourceforge.net/networking.html> That site
- has examples of the UML command line to use to enable Multicast
- networking, and notes about the security of this approach.

- If you need UMLs on multiple physical hosts to communicate as if
- they shared an Ethernet network, say Y. If you need to communicate
- with other IP machines, make sure you select one of the other
- transports (possibly in addition to Multicast; they're not
- exclusive). If you don't need to network UMLs say N to each of

-
-config UML_NET_SLIRP
- bool "SLiRP transport"
- depends on UML_NET
- help
- The SLiRP User-Mode Linux network transport allows a running UML
- to network by invoking a program that can handle SLIP encapsulated
- packets. This is commonly (but not limited to) the application
- known as SLiRP, a program that can re-socket IP packets back onto
- the host on which it is run. Only IP packets are supported,
- unlike other network transports that can handle all Ethernet
- frames. In general, slirp allows the UML the same IP connectivity
- to the outside world that the host user is permitted, and unlike
- other transports, SLiRP works without the need of root level
- privleges, setuid binaries, or SLIP devices on the host. This
- also means not every type of connection is possible, but most
- situations can be accomodated with carefully crafted slirp
- commands that can be passed along as part of the network device's
- setup string. The effect of this transport on the UML is similar
- that of a host behind a firewall that masquerades all network
- connections passing through it (but is less secure).
-
- To use this you should first have slirp compiled somewhere
- accessible on the host, and have read its documentation. If you
- don't need UML networking, say N.

- * Semaphores are implemented using a two-way counter:

- * that tries to acquire the semaphore, while the "sleeping"
- * variable is a count of such acquires.
- *
- * Notably, the inline "up()" and "down()" functions can
- * efficiently test if they need to do any extra work (up
- * needs to do something only if count was negative before
- * the increment operation.
- *
- * "sleeping" and the contention routine ordering is protected
- * by the spinlock in the semaphore's waitqueue head.
- *
- * Note that these functions are only called when there is
- * contention on the lock, and as such all this is the
- * "non-critical" part of the whole semaphore business. The
- * critical part is the inline stuff in <asm/semaphore.h>

+ *
+ * Contiguous method:

+ * image size.
+ *
+ * Packetized method:
+ * The driver writes the incoming packet image by allocating a new packet

Based on i2c/chips/eeprom.c
- The MAX6875 has two EEPROM sections: config and user.
- At reset, the config EEPROM is read into the registers.
+ The MAX6875 has a bank of registers and two banks of EEPROM.
+ Address ranges are defined as follows:
+ * 0x0000 - 0x0046 = configuration registers
+ * 0x8000 - 0x8046 = configuration EEPROM
+ * 0x8100 - 0x82FF = user EEPROM
- This driver make 3 binary files available in sysfs:
- reg_config - direct access to the registers
- eeprom_config - acesses configuration eeprom space
- eeprom_user - free for application use
+ This driver makes the user EEPROM available for read.
- In our application, we put device serial & model numbers in user eeprom.
+ The registers & config EEPROM should be accessed via i2c-dev.
- Notes:
- 1) The datasheet says that register 0x44 / EEPROM 0x8044 should NOT
- be overwritten, so the driver explicitly prevents that.
- 2) It's a good idea to keep the config (0x45) locked in config EEPROM.
- You can temporarily enable config writes by changing register 0x45.
+ The MAX6875 ignores the lowest address bit, so each chip responds to
+ two addresses - 0x50/0x51 and 0x52/0x53.
+
+ Note that the MAX6875 uses i2c_smbus_write_byte_data() to set the read
+ address, so this driver is destructive if loaded for the wrong EEPROM chip.

+
+ See <file:Documentation/networking/README.ipw2100> for information on
+ the capabilities currently enabled in this driver and for tips
+ for debugging issues and problems.
+
+ In order to use this driver, you will need a firmware image for it.
+ You can obtain the firmware from
+ <http://ipw2100.sf.net/>. Once you have the firmware image, you
+ will need to place it in /etc/firmware.
+
+ You will also very likely need the Wireless Tools in order to
+ configure your card:
+
+ <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
+
+ If you want to compile the driver as a module ( = code which can be
+ inserted in and remvoed from the running kernel whenever you want),
+ say M here and read <file:Documentation/modules.txt>. The module
+ will be called ipw2100.ko.

+ mode, no packets can be sent.
+
+config IPW_DEBUG
+ bool "Enable full debugging output in IPW2100 module."
+ depends on IPW2100
+ ---help---
+ This option will enable debug tracing output for the IPW2100.
+
+ This will result in the kernel module being ~60k larger. You can
+ control which debug output is sent to the kernel log by setting the
+ value in
+
+ /sys/bus/pci/drivers/ipw2100/debug_level
+
+ This entry will only exist if this option is enabled.
+
+ If you are not trying to debug or develop the IPW2100 driver, you

+
+ /sys/bus/pci/drivers/ipw2200/debug_level
+
+ This entry will only exist if this option is enabled.
+
+ To set a value, simply echo an 8-byte hex value to the same file:

+ *
+ * FIX:
+ * - there is currently no way of associating TX packets to correct wds device
+ * when TX Exc/OK event occurs, so all tx_packets and some
+ * tx_errors/tx_dropped are added to the main netdevice; using sw_support
+ * field in txdesc might be used to fix this (using Alloc event to increment
+ * tx_packets would need some further info in txfid table)
+ *
+ * Buffer Access Path (BAP) usage:
+ * Prism2 cards have two separate BAPs for accessing the card memory. These
+ * should allow concurrent access to two different frames and the driver
+ * previously used BAP0 for sending data and BAP1 for receiving data.
+ * However, there seems to be number of issues with concurrent access and at
+ * least one know hardware bug in using BAP0 and BAP1 concurrently with PCI
+ * Prism2.5. Therefore, the driver now only uses BAP0 for moving data between
+ * host and card memories. BAP0 accesses are protected with local->baplock
+ * (spin_lock_bh) to prevent concurrent use.

+
+ Initial driver on which this is based was developed by Janusz Gorycki,
+ Maciej Urbaniak, and Maciej Sosnowski.
+
+ Promiscuous mode support added by Jacek Wysoczynski and Maciej Urbaniak.
+
+Theory of Operation
+
+Tx - Commands and Data
+
+Firmware and host share a circular queue of Transmit Buffer Descriptors (TBDs)
+Each TBD contains a pointer to the physical (dma_addr_t) address of data being
+sent to the firmware as well as the length of the data.
+
+The host writes to the TBD queue at the WRITE index. The WRITE index points
+to the _next_ packet to be written and is advanced when after the TBD has been
+filled.
+
+The firmware pulls from the TBD queue at the READ index. The READ index points
+to the currently being read entry, and is advanced once the firmware is
+done with a packet.
+
+When data is sent to the firmware, the first TBD is used to indicate to the
+firmware if a Command or Data is being sent. If it is Command, all of the
+command information is contained within the physical address referred to by the
+TBD. If it is Data, the first TBD indicates the type of data packet, number
+of fragments, etc. The next TBD then referrs to the actual packet location.
+
+The Tx flow cycle is as follows:
+
+1) ipw2100_tx() is called by kernel with SKB to transmit
+2) Packet is move from the tx_free_list and appended to the transmit pending
+ list (tx_pend_list)
+3) work is scheduled to move pending packets into the shared circular queue.
+4) when placing packet in the circular queue, the incoming SKB is DMA mapped
+ to a physical address. That address is entered into a TBD. Two TBDs are
+ filled out. The first indicating a data packet, the second referring to the
+ actual payload data.
+5) the packet is removed from tx_pend_list and placed on the end of the
+ firmware pending list (fw_pend_list)
+6) firmware is notified that the WRITE index has
+7) Once the firmware has processed the TBD, INTA is triggered.
+8) For each Tx interrupt received from the firmware, the READ index is checked
+ to see which TBDs are done being processed.
+9) For each TBD that has been processed, the ISR pulls the oldest packet
+ from the fw_pend_list.
+10)The packet structure contained in the fw_pend_list is then used
+ to unmap the DMA address and to free the SKB originally passed to the driver
+ from the kernel.
+11)The packet structure is placed onto the tx_free_list
+
+The above steps are the same for commands, only the msg_free_list/msg_pend_list
+are used instead of tx_free_list/tx_pend_list
+
+...
+
+Critical Sections / Locking :
+
+There are two locks utilized. The first is the low level lock (priv->low_lock)
+that protects the following:
+
+- Access to the Tx/Rx queue lists via priv->low_lock. The lists are as follows:
+
+ tx_free_list : Holds pre-allocated Tx buffers.
+ TAIL modified in __ipw2100_tx_process()
+ HEAD modified in ipw2100_tx()
+
+ tx_pend_list : Holds used Tx buffers waiting to go into the TBD ring
+ TAIL modified ipw2100_tx()
+ HEAD modified by ipw2100_tx_send_data()
+
+ msg_free_list : Holds pre-allocated Msg (Command) buffers
+ TAIL modified in __ipw2100_tx_process()
+ HEAD modified in ipw2100_hw_send_command()
+
+ msg_pend_list : Holds used Msg buffers waiting to go into the TBD ring
+ TAIL modified in ipw2100_hw_send_command()
+ HEAD modified in ipw2100_tx_send_commands()
+
+ The flow of data on the TX side is as follows:
+
+ MSG_FREE_LIST + COMMAND => MSG_PEND_LIST => TBD => MSG_FREE_LIST
+ TX_FREE_LIST + DATA => TX_PEND_LIST => TBD => TX_FREE_LIST
+
+ The methods that work on the TBD ring are protected via priv->low_lock.
+
+- The internal data state of the device itself
+- Access to the firmware read/write indexes for the BD queues
+ and associated logic
+
+All external entry functions are locked with the priv->action_lock to ensure
+that only one external action is invoked at a time.

+ * Rx theory of operation
+ *
+ * The host allocates 32 DMA target addresses and passes the host address
+ * to the firmware at register CX2_RFDS_TABLE_LOWER + N * RFD_SIZE where N is
+ * 0 to 31
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two index registers for managing the Rx buffers.
+ *
+ * The READ index maps to the first position that the firmware may be writing
+ * to -- the driver can read up to (but not including) this position and get
+ * good data.
+ * The READ index is managed by the firmware once the card is enabled.
+ *
+ * The WRITE index maps to the last position the driver has read from -- the
+ * position preceding WRITE is the last slot the firmware can place a packet.
+ *
+ * The queue is empty (no good data) if WRITE = READ - 1, and is full if
+ * WRITE = READ.
+ *
+ * During initialization the host sets up the READ queue position to the first
+ * INDEX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer it will advance the READ index
+ * and fire the RX interrupt. The driver can then query the READ index and
+ * process as many packets as possible, moving the WRITE index forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When
+ * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ * to replensish the ipw->rxq->rx_free.
+ * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the
+ * ipw->rxq is replenished and the READ INDEX is updated (updating the
+ * 'processed' and 'read' driver indexes as well)
+ * + A received packet is processed and handed to the kernel network stack,
+ * detached from the ipw->rxq. The driver 'processed' index is updated.
+ * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
+ * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
+ * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
+ * were enough free buffers and RX_STALLED is set it is cleared.
+ *
+ *
+ * Driver sequence:
+ *
+ * ipw_rx_queue_alloc() Allocates rx_free
+ * ipw_rx_queue_replenish() Replenishes rx_free list from rx_used, and calls
+ * ipw_rx_queue_restock
+ * ipw_rx_queue_restock() Moves available buffers from rx_free into Rx
+ * queue, updates firmware pointers, and updates
+ * the WRITE index. If insufficient rx_free buffers
+ * are available, schedules ipw_rx_queue_replenish
+ *
+ * -- enable interrupts --
+ * ISR - ipw_rx() Detach ipw_rx_mem_buffers from pool up to the
+ * READ INDEX, detaching the SKB from the pool.
+ * Moves the packet buffer from queue to rx_used.
+ * Calls ipw_rx_queue_restock to refill any empty
+ * slots.

+ * Embedded Linux Lab - 10LE Instituto Nokia de Tecnologia - INdT
+ *
+ * A new process specific entry (smaps) included in /proc. It shows the
+ * size of rss for each memory area. The maps entry lacks information
+ * about physical memory size (rss) for each mapped file, i.e.,
+ * rss information for executables and library files.
+ * This additional information is useful for any tools that need to know
+ * about physical memory consumption for a process specific library.
+ *
+ * Changelog:
+ * 21-Feb-2005
+ * Embedded Linux Lab - 10LE Instituto Nokia de Tecnologia - INdT
+ * Pud inclusion in the page table walking.
+ *
+ * ChangeLog:
+ * 10-Mar-2005
+ * 10LE Instituto Nokia de Tecnologia - INdT:
+ * A better way to walks through the page table as suggested by Hugh Dickins.
+ *
+ * Simo Piiroinen <simo.piiroinen@nokia.com>:
+ * Smaps information related to shared, private, clean and dirty pages.
+ *
+ * Paul Mundt <paul.mundt@nokia.com>:
+ * Overall revision about smaps.

+ Say Y here to enable the kernel to detect "soft lockups",
+ which are bugs that cause the kernel to loop in kernel
+ mode for more than 10 seconds, without giving other tasks a
+ chance to run.
+
+ When a soft-lockup is detected, the kernel will print the
+ current stack trace (which you should report), but the
+ system will stay locked up. This feature has negligible
+ overhead.
+
+ (Note that "hard lockups" are separate type of bugs that
+ can be detected via the NMI-watchdog, on platforms that
+ support it.)

+ setting the value in
+
+ /proc/net/ieee80211/debug_level
+
+ For example:
+
+ % echo 0x00000FFO > /proc/net/ieee80211/debug_level
+
+ For a list of values you can assign to debug_level, you
+ can look at the bit mask values in <net/ieee80211.h>
+
+ If you are not trying to debug or develop the ieee80211
+ subsystem, you most likely want to say N here.

+In the event that fragmentation is required, the incoming payload is split into
+N parts of size ieee->fts. The first fragment contains the SNAP header and the
+remaining packets are just data.
+
+If encryption is enabled, each fragment payload size is reduced by enough space
+to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
+So if you have 1500 bytes of payload with ieee->fts set to 500 without
+encryption it will take 3 frames. With WEP it will take 4 frames as the
+payload of each frame is reduced to 492 bytes.

+ NetBIOS name service requests are sent as broadcast messages from an

+ same port. This make them hard to firewall properly because connection
+ tracking doesn't deal with broadcasts. This helper tracks locally
+ originating NetBIOS name service requests and the corresponding
+ responses. It relies on correct IP address configuration, specifically
+ netmask and broadcast address. When properly configured, the output
+ of "ip address show" should look similar to this:
+
