IPMI defines a standard watchdog timer. You can enable this with the
'IPMI Watchdog Timer' config option. If you compile the driver into

ipmi_watchdog - IPMI requires systems to have a very capable watchdog
timer. This driver implements the standard Linux watchdog timer
only the first three parameters (si type, address type, and address)
are used for the comparison. Any options are ignored for removing.
-The SMBus Driver
-----------------
-
-The SMBus driver allows up to 4 SMBus devices to be configured in the
-system. By default, the driver will register any SMBus interfaces it finds
-in the I2C address range of 0x20 to 0x4f on any adapter. You can change this
-at module load time (for a module) with:
-
- modprobe ipmi_smb.o
- addr=<adapter1>,<i2caddr1>[,<adapter2>,<i2caddr2>[,...]]
- dbg=<flags1>,<flags2>...
- [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.
-
-The debug flags are bit flags for each BMC found, they are:
-IPMI messages: 1, driver state: 2, timing: 4, I2C probe: 8
-
-Setting smb_defaultprobe to zero disabled the default probing of SMBus
-interfaces at address range 0x20 to 0x4f. This means that only the
-BMCs specified on the smb_addr line will be detected.
-
-Setting smb_dbg_probe to 1 will enable debugging of the probing and
-detection process for BMCs on the SMBusses.
-
-Discovering the IPMI compliant BMC on the SMBus can cause devices
-on the I2C bus to fail. The SMBus driver writes a "Get Device ID" IPMI
-message as a block write to the I2C bus and waits for a response.
-This action can be detrimental to some I2C devices. It is highly recommended
-that the known I2c address be given to the SMBus driver in the smb_addr
-parameter. The default address range will not be used when a smb_addr
-parameter is provided.
-
-When compiled into the kernel, the addresses can be specified on the
-kernel command line as:
-
- ipmb_smb.addr=<adapter1>,<i2caddr1>[,<adapter2>,<i2caddr2>[,...]]
- ipmi_smb.dbg=<flags1>,<flags2>...
- ipmi_smb.defaultprobe=0 ipmi_smb.dbg_probe=1
-
-These are the same options as on the module command line.
-
-Note that you might need some I2C changes if CONFIG_IPMI_PANIC_EVENT
-is enabled along with this, so the I2C driver knows to run to
-completion during sending a panic event.

+ Why use PACKET_MMAP
--------------------------------------------------------------------------------
-In Linux 2.4/2.6 if PACKET_MMAP is not enabled, the capture process is very
-inefficient. It uses very limited buffers and requires one system call
-to capture each packet, it requires two if you want to get packet's

+(like libpcap always does).
In the other hand PACKET_MMAP is very efficient. PACKET_MMAP provides a size
configurable circular buffer mapped in user space that can be used to either
send or receive packets. This way reading packets just needs to wait for them,
most of the time there is no need to issue a single system call. Concerning
transmission, multiple packets can be sent through one system call to get the

It's fine to use PACKET_MMAP to improve the performance of the capture and
transmission process, but it isn't everything. At least, if you are capturing

--------------------------------------------------------------------------------
+ How to use mmap() to improve capture process
socket creation and destruction is straight forward, and is done
the same way with or without PACKET_MMAP:
-int fd;
-
-fd= socket(PF_PACKET, mode, htons(ETH_P_ALL))
+ int fd = socket(PF_PACKET, mode, htons(ETH_P_ALL));

A complete tutorial is available at: http://wiki.gnu-log.net/
+By default, the user should put data at :
+ frame base + TPACKET_HDRLEN - sizeof(struct sockaddr_ll)
+
+So, whatever you choose for the socket mode (SOCK_DGRAM or SOCK_RAW),
+the beginning of the user data will be at :
+ frame base + TPACKET_ALIGN(sizeof(struct tpacket_hdr))
+
+If you wish to put user data at a custom offset from the beginning of
+the frame (for payload alignment with SOCK_RAW mode for instance) you
+can set tp_net (with SOCK_DGRAM) or tp_mac (with SOCK_RAW). In order
+to make this work it must be enabled previously with setsockopt()
+and the PACKET_TX_HAS_OFF option.
+
--------------------------------------------------------------------------------
+ PACKET_MMAP settings
--------------------------------------------------------------------------------
-
To setup PACKET_MMAP from user level code is done with a call like
- Capture process
frames_per_block * tp_block_nr == tp_frame_nr
-
Lets see an example, with the following values:
tp_block_size= 4096
account when choosing the frame_size. See "Mapping and use of the circular
buffer (ring)".

+ PACKET_MMAP setting constraints
--------------------------------------------------------------------------------
The pagesize can also be determined dynamically with the getpagesize (2)
system call.

Block number limit
--------------------

kmalloc allocates any number of bytes of physically contiguous memory from
a pool of pre-determined sizes. This pool of memory is maintained by the slab
allocator which is at the end the responsible for doing the allocation and
131072/4 = 32768 blocks
-
PACKET_MMAP buffer size calculator
------------------------------------
and hence the buffer will have a 262144 MiB size. So it can hold
262144 MiB / 2048 bytes = 134217728 frames
-
Actually, this buffer size is not possible with an i386 architecture.
Remember that the memory is allocated in kernel space, in the case of
an i386 kernel's memory size is limited to 1GiB.

It doesn't incur in a race condition to first check the status value and
then poll for frames.

++ Transmission process
Those defines are also used for transmission:
pfd.events = POLLOUT;
retval = poll(&pfd, 1, timeout);
+-------------------------------------------------------------------------------
++ What TPACKET versions are available and when to use them?
+-------------------------------------------------------------------------------
+
+ int val = tpacket_version;
+ setsockopt(fd, SOL_PACKET, PACKET_VERSION, &val, sizeof(val));
+ getsockopt(fd, SOL_PACKET, PACKET_VERSION, &val, sizeof(val));
+
+where 'tpacket_version' can be TPACKET_V1 (default), TPACKET_V2, TPACKET_V3.
+
+TPACKET_V1:
+ - Default if not otherwise specified by setsockopt(2)
+ - RX_RING, TX_RING available
+ - VLAN metadata information available for packets
+ (TP_STATUS_VLAN_VALID)
+
+TPACKET_V1 --> TPACKET_V2:
+ - Made 64 bit clean due to unsigned long usage in TPACKET_V1
+ structures, thus this also works on 64 bit kernel with 32 bit
+ userspace and the like
+ - Timestamp resolution in nanoseconds instead of microseconds
+ - RX_RING, TX_RING available
+ - How to switch to TPACKET_V2:
+ 1. Replace struct tpacket_hdr by struct tpacket2_hdr
+ 2. Query header len and save
+ 3. Set protocol version to 2, set up ring as usual
+ 4. For getting the sockaddr_ll,
+ use (void *)hdr + TPACKET_ALIGN(hdrlen) instead of
+ (void *)hdr + TPACKET_ALIGN(sizeof(struct tpacket_hdr))
+
+TPACKET_V2 --> TPACKET_V3:
+ - Flexible buffer implementation:
+ 1. Blocks can be configured with non-static frame-size
+ 2. Read/poll is at a block-level (as opposed to packet-level)
+ 3. Added poll timeout to avoid indefinite user-space wait
+ on idle links
+ 4. Added user-configurable knobs:
+ 4.1 block::timeout
+ 4.2 tpkt_hdr::sk_rxhash
+ - RX Hash data available in user space
+ - Currently only RX_RING available
+
+-------------------------------------------------------------------------------
++ AF_PACKET fanout mode

+
+In the AF_PACKET fanout mode, packet reception can be load balanced among

3) Command line options
Driver parameters can be also passed in command line by using:
The incoming packets are stored, by the DMA, in a list of pre-allocated socket
buffers in order to avoid the memcpy (Zero-copy).
-4.3) Timer-Driver Interrupt
-Instead of having the device that asynchronously notifies the frame receptions,
-the driver configures a timer to generate an interrupt at regular intervals.
-Based on the granularity of the timer, the frames that are received by the
-device will experience different levels of latency. Some NICs have dedicated
-timer device to perform this task. STMMAC can use either the RTC device or the
-TMU channel 2 on STLinux platforms.
-The timers frequency can be passed to the driver as parameter; when change it,
-take care of both hardware capability and network stability/performance impact.
-Several performance tests on STM platforms showed this optimisation allows to
-spare the CPU while having the maximum throughput.
+4.3) Interrupt Mitigation
+The driver is able to mitigate the number of its DMA interrupts
+using NAPI for the reception on chips older than the 3.50.
+New chips have an HW RX-Watchdog used for this mitigation.
+
+On Tx-side, the mitigation schema is based on a SW timer that calls the
+tx function (stmmac_tx) to reclaim the resource after transmitting the
+frames.
+Also there is another parameter (like a threshold) used to program
+the descriptors avoiding to set the interrupt on completion bit in
+when the frame is sent (xmit).
+
+Mitigation parameters can be tuned by ethtool.

+何为 IRQ?
+
+一个 IRQ 是来自某个设备的一个中断请求。目前，它们可以来自一个硬件引脚，
+或来自一个数据包。多个设备可能连接到同个硬件引脚，从而共享一个 IRQ。
+
+一个 IRQ 编号是用于告知硬件中断源的内核标识。通常情况下，这是一个
+全局 irq_desc 数组的索引，但是除了在 linux/interrupt.h 中的实现，
+具体的细节是体系结构特定的。
+
+一个 IRQ 编号是设备上某个可能的中断源的枚举。通常情况下，枚举的编号是
+该引脚在系统内中断控制器的所有输入引脚中的编号。对于 ISA 总线中的情况，
+枚举的是在两个 i8259 中断控制器中 16 个输入引脚。
+
+架构可以对 IRQ 编号指定额外的含义，在硬件涉及任何手工配置的情况下，
+是被提倡的。ISA 的 IRQ 是一个分配这类额外含义的典型例子。

+ 启动 AArch64 Linux
+ ==================
+
+作者: Will Deacon <will.deacon@arm.com>
+日期: 2012 年 09 月 07 日
+
+本文档基于 Russell King 的 ARM 启动文档，且适用于所有公开发布的
+AArch64 Linux 内核代码。
+
+AArch64 异常模型由多个异常级别（EL0 - EL3）组成，对于 EL0 和 EL1
+异常级有对应的安全和非安全模式。EL2 是系统管理级，且仅存在于
+非安全模式下。EL3 是最高特权级，且仅存在于安全模式下。
+
+基于本文档的目的，我们将简单地使用‘引导装载程序’（‘boot loader’）
+这个术语来定义在将控制权交给 Linux 内核前 CPU 上执行的所有软件。
+这可能包含安全监控和系统管理代码，或者它可能只是一些用于准备最小启动
+环境的指令。
+
+基本上，引导装载程序（至少）应实现以下操作：
+
+1、设置和初始化 RAM
+2、设置设备树数据
+3、解压内核映像
+4、调用内核映像
+
+
+1、设置和初始化 RAM
+-----------------
+
+必要性: 强制
+
+引导装载程序应该找到并初始化系统中所有内核用于保持系统变量数据的 RAM。
+这个操作的执行是设备依赖的。（它可能使用内部算法来自动定位和计算所有
+RAM，或可能使用对这个设备已知的 RAM 信息，还可能使用任何引导装载程序
+设计者想到的匹配方法。）
+
+
+2、设置设备树数据
+---------------
+
+必要性: 强制
+
+设备树数据块（dtb）大小必须不大于 2 MB，且位于从内核映像起始算起第一个
+512MB 内的 2MB 边界上。这使得内核可以通过初始页表中的单个节描述符来
+映射此数据块。
+
+
+3、解压内核映像
+-------------
+
+必要性: 可选
+
+AArch64 内核当前没有提供自解压代码，因此如果使用了压缩内核映像文件
+（比如 Image.gz），则需要通过引导装载程序（使用 gzip 等）来进行解压。
+若引导装载程序没有实现这个需求，就要使用非压缩内核映像文件。
+
+
+4、调用内核映像
+-------------
+
+必要性: 强制
+
+已解压的内核映像包含一个 32 字节的头，内容如下：
+
+ u32 magic = 0x14000008; /* 跳转到 stext, 小端 */
+ u32 res0 = 0; /* 保留 */
+ u64 text_offset; /* 映像装载偏移 */
+ u64 res1 = 0; /* 保留 */
+ u64 res2 = 0; /* 保留 */
+
+映像必须位于系统 RAM 起始处的特定偏移（当前是 0x80000）。系统 RAM
+的起始地址必须是以 2MB 对齐的。
+
+在跳转入内核前，必须符合以下状态：
+
+- 停止所有 DMA 设备，这样内存数据就不会因为虚假网络包或磁盘数据而
+ 被破坏。这可能可以节省你许多的调试时间。
+
+- 主 CPU 通用寄存器设置
+ x0 = 系统 RAM 中设备树数据块（dtb）的物理地址。
+ x1 = 0 (保留，将来可能使用)
+ x2 = 0 (保留，将来可能使用)
+ x3 = 0 (保留，将来可能使用)
+
+- CPU 模式
+ 所有形式的中断必须在 PSTATE.DAIF 中被屏蔽（Debug、SError、IRQ
+ 和 FIQ）。
+ CPU 必须处于 EL2（推荐，可访问虚拟化扩展）或非安全 EL1 模式下。
+
+- 高速缓存、MMU
+ MMU 必须关闭。
+ 指令缓存开启或关闭都可以。
+ 数据缓存必须关闭且无效。
+ 外部高速缓存（如果存在）必须配置并禁用。
+
+- 架构计时器
+ CNTFRQ 必须设定为计时器的频率。
+ 如果在 EL1 模式下进入内核，则 CNTHCTL_EL2 中的 EL1PCTEN (bit 0)
+ 必须置位。
+
+- 一致性
+ 通过内核启动的所有 CPU 在内核入口地址上必须处于相同的一致性域中。
+ 这可能要根据具体实现来定义初始化过程，以使能每个CPU上对维护操作的
+ 接收。
+
+- 系统寄存器
+ 在进入内核映像的异常级中，所有构架中可写的系统寄存器必须通过软件
+ 在一个更高的异常级别下初始化，以防止在 未知 状态下运行。
+
+引导装载程序必须在每个 CPU 处于以下状态时跳入内核入口：
+
+- 主 CPU 必须直接跳入内核映像的第一条指令。通过此 CPU 传递的设备树
+ 数据块必须在每个 CPU 节点中包含以下内容：
+
+ 1、‘enable-method’属性。目前，此字段支持的值仅为字符串“spin-table”。
+
+ 2、‘cpu-release-addr’标识一个 64-bit、初始化为零的内存位置。
+
+ 引导装载程序必须生成这些设备树属性，并在跳入内核入口之前将其插入
+ 数据块。
+
+- 任何辅助 CPU 必须在内存保留区（通过设备树中的 /memreserve/ 域传递
+ 给内核）中自旋于内核之外，轮询它们的 cpu-release-addr 位置（必须
+ 包含在保留区中）。可通过插入 wfe 指令来降低忙循环开销，而主 CPU 将
+ 发出 sev 指令。当对 cpu-release-addr 所指位置的读取操作返回非零值
+ 时，CPU 必须直接跳入此值所指向的地址。
+
+- 辅助 CPU 通用寄存器设置
+ x0 = 0 (保留，将来可能使用)
+ x1 = 0 (保留，将来可能使用)
+ x2 = 0 (保留，将来可能使用)
+ x3 = 0 (保留，将来可能使用)

+ Linux 在 AArch64 中的内存布局
+ ===========================
+
+作者: Catalin Marinas <catalin.marinas@arm.com>
+日期: 2012 年 02 月 20 日
+
+本文档描述 AArch64 Linux 内核所使用的虚拟内存布局。此构架可以实现
+页大小为 4KB 的 4 级转换表和页大小为 64KB 的 3 级转换表。
+
+AArch64 Linux 使用页大小为 4KB 的 3 级转换表配置，对于用户和内核
+都有 39-bit (512GB) 的虚拟地址空间。对于页大小为 64KB的配置，仅
+使用 2 级转换表，但内存布局相同。
+
+用户地址空间的 63:39 位为 0，而内核地址空间的相应位为 1。TTBRx 的
+选择由虚拟地址的 63 位给出。swapper_pg_dir 仅包含内核（全局）映射，
+而用户 pgd 仅包含用户（非全局）映射。swapper_pgd_dir 地址被写入
+TTBR1 中，且从不写入 TTBR0。

- * Linux system call numbers.
- *
- * Cary Coutant says that we should just use another syscall gateway
- * page to avoid clashing with the HPUX space, and I think he's right:
- * it will would keep a branch out of our syscall entry path, at the
- * very least. If we decide to change it later, we can ``just'' tweak
- * the LINUX_GATEWAY_ADDR define at the bottom and make __NR_Linux be
- * 1024 or something. Oh, and recompile libc. =)
- *
- * 64-bit HPUX binaries get the syscall gateway address passed in a register
- * from the kernel at startup, which seems a sane strategy.

+/* The macros in this file implement an exponential backoff facility
+ * for atomic operations.
+ *
+ * When multiple threads compete on an atomic operation, it is
+ * possible for one thread to be continually denied a successful
+ * completion of the compare-and-swap instruction. Heavily
+ * threaded cpu implementations like Niagara can compound this
+ * problem even further.
+ *
+ * When an atomic operation fails and needs to be retried, we spin a
+ * certain number of times. At each subsequent failure of the same
+ * operation we double the spin count, realizing an exponential
+ * backoff.
+ *
+ * When we spin, we try to use an operation that will cause the
+ * current cpu strand to block, and therefore make the core fully
+ * available to any other other runnable strands. There are two
+ * options, based upon cpu capabilities.
+ *
+ * On all cpus prior to SPARC-T4 we do three dummy reads of the
+ * condition code register. Each read blocks the strand for something
+ * between 40 and 50 cpu cycles.
+ *
+ * For SPARC-T4 and later we have a special "pause" instruction
+ * available. This is implemented using writes to register %asr27.
+ * The cpu will block the number of cycles written into the register,
+ * unless a disrupting trap happens first. SPARC-T4 specifically
+ * implements pause with a granularity of 8 cycles. Each strand has
+ * an internal pause counter which decrements every 8 cycles. So the
+ * chip shifts the %asr27 value down by 3 bits, and writes the result
+ * into the pause counter. If a value smaller than 8 is written, the
+ * chip blocks for 1 cycle.
+ *
+ * To achieve the same amount of backoff as the three %ccr reads give
+ * on earlier chips, we shift the backoff value up by 7 bits. (Three
+ * %ccr reads block for about 128 cycles, 1 << 7 == 128) We write the
+ * whole amount we want to block into the pause register, rather than
+ * loop writing 128 each time.

* Copy thread.
*
+ * There are two modes in which this function is called:
+ * 1) Userspace thread creation,
+ * regs != NULL, usp_thread_fn is userspace stack pointer.
+ * It is expected to copy parent regs (in case CLONE_VM is not set
+ * in the clone_flags) and set up passed usp in the childregs.
+ * 2) Kernel thread creation,
+ * regs == NULL, usp_thread_fn is the function to run in the new thread
+ * and thread_fn_arg is its parameter.
+ * childregs are not used for the kernel threads.
+ *
* The stack layout for the new thread looks like this:
*
- * +------------------------+ <- sp in childregs (= tos)
+ * +------------------------+
* | childregs |
* +------------------------+ <- thread.sp = sp in dummy-frame
* | dummy-frame | (saved in dummy-frame spill-area)
* +------------------------+
*
- * We create a dummy frame to return to ret_from_fork:
- * a0 points to ret_from_fork (simulating a call4)
+ * We create a dummy frame to return to either ret_from_fork or
+ * ret_from_kernel_thread:
+ * a0 points to ret_from_fork/ret_from_kernel_thread (simulating a call4)
* sp points to itself (thread.sp)
- * a2, a3 are unused.
+ * a2, a3 are unused for userspace threads,
+ * a2 points to thread_fn, a3 holds thread_fn arg for kernel threads.
*
* Note: This is a pristine frame, so we don't need any spill region on top of
* childregs.
+ *
+ * The fun part: if we're keeping the same VM (i.e. cloning a thread,
+ * not an entire process), we're normally given a new usp, and we CANNOT share
+ * any live address register windows. If we just copy those live frames over,
+ * the two threads (parent and child) will overflow the same frames onto the
+ * parent stack at different times, likely corrupting the parent stack (esp.
+ * if the parent returns from functions that called clone() and calls new
+ * ones, before the child overflows its now old copies of its parent windows).
+ * One solution is to spill windows to the parent stack, but that's fairly
+ * involved. Much simpler to just not copy those live frames across.

+ tristate "Kvaser CAN/USB interface"
+ ---help---
+ This driver adds support for Kvaser CAN/USB devices like Kvaser
+ Leaf Light.
+
+ The driver gives support for the following devices:
+ - Kvaser Leaf Light
+ - Kvaser Leaf Professional HS
+ - Kvaser Leaf SemiPro HS
+ - Kvaser Leaf Professional LS
+ - Kvaser Leaf Professional SWC
+ - Kvaser Leaf Professional LIN
+ - Kvaser Leaf SemiPro LS
+ - Kvaser Leaf SemiPro SWC
+ - Kvaser Memorator II HS/HS
+ - Kvaser USBcan Professional HS/HS
+ - Kvaser Leaf Light GI
+ - Kvaser Leaf Professional HS (OBD-II connector)
+ - Kvaser Memorator Professional HS/LS
+ - Kvaser Leaf Light "China"
+ - Kvaser BlackBird SemiPro
+ - Kvaser USBcan R
+
+ If unsure, say N.
+
+ To compile this driver as a module, choose M here: the
+ module will be called kvaser_usb.

* Notes on locking strategy:
*
- * Most CSRs are 128-bit (oword) and therefore cannot be read or
- * written atomically. Access from the host is buffered by the Bus
- * Interface Unit (BIU). Whenever the host reads from the lowest
- * address of such a register, or from the address of a different such
- * register, the BIU latches the register's value. Subsequent reads
- * from higher addresses of the same register will read the latched
- * value. Whenever the host writes part of such a register, the BIU
- * collects the written value and does not write to the underlying
- * register until all 4 dwords have been written. A similar buffering
- * scheme applies to host access to the NIC's 64-bit SRAM.
+ * Many CSRs are very wide and cannot be read or written atomically.
+ * Writes from the host are buffered by the Bus Interface Unit (BIU)
+ * up to 128 bits. Whenever the host writes part of such a register,
+ * the BIU collects the written value and does not write to the
+ * underlying register until all 4 dwords have been written. A
+ * similar buffering scheme applies to host access to the NIC's 64-bit
+ * SRAM.
*
- * Access to different CSRs and 64-bit SRAM words must be serialised,
- * since interleaved access can result in lost writes or lost
- * information from read-to-clear fields. We use efx_nic::biu_lock
- * for this. (We could use separate locks for read and write, but
- * this is not normally a performance bottleneck.)
+ * Writes to different CSRs and 64-bit SRAM words must be serialised,
+ * since interleaved access can result in lost writes. We use
+ * efx_nic::biu_lock for this.
+ *
+ * We also serialise reads from 128-bit CSRs and SRAM with the same
+ * spinlock. This may not be necessary, but it doesn't really matter
+ * as there are no such reads on the fast path.
*
* The DMA descriptor pointers (RX_DESC_UPD and TX_DESC_UPD) are
* 128-bit but are special-cased in the BIU to avoid the need for

- * Utility code which helps transforming between two different time
- * bases, called "source" and "target" time in this code.
- *
- * Source time has to be provided via the timecounter API while target
- * time is accessed via a function callback whose prototype
- * intentionally matches ktime_get() and ktime_get_real(). These
- * interfaces where chosen like this so that the code serves its
- * initial purpose without additional glue code.
- *
- * This purpose is synchronizing a hardware clock in a NIC with system
- * time, in order to implement the Precision Time Protocol (PTP,
- * IEEE1588) with more accurate hardware assisted time stamping. In
- * that context only synchronization against system time (=
- * ktime_get_real()) is currently needed. But this utility code might
- * become useful in other situations, which is why it was written as
- * general purpose utility code.
- *
- * The source timecounter is assumed to return monotonically
- * increasing time (but this code does its best to compensate if that
- * is not the case) whereas target time may jump.
- *
- * The target time corresponding to a source time is determined by
- * reading target time, reading source time, reading target time
- * again, then assuming that average target time corresponds to source
- * time. In other words, the assumption is that reading the source
- * time is slow and involves equal time for sending the request and
- * receiving the reply, whereas reading target time is assumed to be
- * fast.

+ * There's also "Wireless USB", using low power short range radios for
+ * peripheral interconnection but otherwise building on the USB framework.
+ *
+ * Note all descriptors are declared '__attribute__((packed))' so that:
+ *
+ * [a] they never get padded, either internally (USB spec writers
+ * probably handled that) or externally;
+ *
+ * [b] so that accessing bigger-than-a-bytes fields will never
+ * generate bus errors on any platform, even when the location of

+ *
+ * [c] for consistency, removing all doubt even when it appears to

+ QFQ+ divides classes into aggregates of at most MAX_AGG_CLASSES
+ classes. Each aggregate is timestamped with a virtual start time S
+ and a virtual finish time F, and scheduled according to its
+ timestamps. S and F are computed as a function of a system virtual
+ time function V. The classes within each aggregate are instead
+ scheduled with DRR.
+
+ To speed up operations, QFQ+ divides also aggregates into a limited
+ number of groups. Which group a class belongs to depends on the
+ ratio between the maximum packet length for the class and the weight
+ of the class. Groups have their own S and F. In the end, QFQ+
+ schedules groups, then aggregates within groups, then classes within
+ aggregates. See [1] and [2] for a full description.

+ * When the weight of a class is increased or the lmax of the class is

+ * before other aggregates waiting for service. This may cause the
+ * above bound to the slot index to be violated for some of these
+ * unlucky aggregates.
+ *
+ * Instead of delaying the activation of the new aggregate, which is
+ * quite complex, the following inaccurate but simple solution is used:
+ * if the slot index is higher than QFQ_MAX_SLOTS-2, then the
