+ Getting Coccinelle
+~~~~~~~~~~~~~~~~~~~~
+
+The semantic patches included in the kernel use the 'virtual rule'
+feature which was introduced in Coccinelle version 0.1.11.
+
+Coccinelle (>=0.2.0) is available through the package manager
+of many distributions, e.g. :
+
+ - Debian (>=squeeze)
+ - Fedora (>=13)
+ - Ubuntu (>=10.04 Lucid Lynx)
+ - OpenSUSE
+ - Arch Linux
+ - NetBSD
+ - FreeBSD
+
+
+You can get the latest version released from the Coccinelle homepage at
+http://coccinelle.lip6.fr/
+
+Once you have it, run the following command:
+
+        ./configure
+        make
+
+as a regular user, and install it with
+
+        sudo make install
+
+
+ Using Coccinelle on the Linux kernel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A Coccinelle-specific target is defined in the top level
+Makefile. This target is named 'coccicheck' and calls the 'coccicheck'
+front-end in the 'scripts' directory.
+
+Four modes are defined: report, patch, context, and org. The mode to
+use is specified by setting the MODE variable with 'MODE=<mode>'.
+
+'report' generates a list in the following format:
+  file:line:column-column: message
+
+'patch' proposes a fix, when possible.
+
+'context' highlights lines of interest and their context in a
+diff-like style.Lines of interest are indicated with '-'.
+
+'org' generates a report in the Org mode format of Emacs.
+
+Note that not all semantic patches implement all modes.
+
+To make a report for every semantic patch, run the following command:
+
+        make coccicheck MODE=report
+
+NB: The 'report' mode is the default one.
+
+To produce patches, run:
+
+        make coccicheck MODE=patch
+
+
+The coccicheck target applies every semantic patch available in the
+subdirectories of 'scripts/coccinelle' to the entire Linux kernel.
+
+For each semantic patch, a changelog message is proposed.  It gives a
+description of the problem being checked by the semantic patch, and
+includes a reference to Coccinelle.
+
+As any static code analyzer, Coccinelle produces false
+positives. Thus, reports must be carefully checked, and patches
+reviewed.
+
+
+ Using Coccinelle with a single semantic patch
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The optional make variable COCCI can be used to check a single
+semantic patch. In that case, the variable must be initialized with
+the name of the semantic patch to apply.
+
+For instance:
+
+        make coccicheck COCCI=<my_SP.cocci> MODE=patch
+or
+        make coccicheck COCCI=<my_SP.cocci> MODE=report
+
+
+ Proposing new semantic patches
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+New semantic patches can be proposed and submitted by kernel
+developers. For sake of clarity, they should be organized in the
+subdirectories of 'scripts/coccinelle/'.
+
+
+ Detailed description of the 'report' mode
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+'report' generates a list in the following format:
+  file:line:column-column: message
+
+Example:
+
+Running
+
+        make coccicheck MODE=report COCCI=scripts/coccinelle/err_cast.cocci
+
+will execute the following part of the SmPL script.

+When the 'patch' mode is available, it proposes a fix for each problem
+identified.

          *
-         * This opcode is meant to set NV_PFB_CFG0 (0x100200) appropriately so
-         * that the hardware can correctly calculate how much VRAM it has
-         * (and subsequently report that value in NV_PFB_CSTATUS (0x10020C))
+         * This opcode is meant to set the PFB memory config registers
+         * appropriately so that we can correctly calculate how much VRAM it
+         * has (on nv10 and better chipsets the amount of installed VRAM is
+         * subsequently reported in NV_PFB_CSTATUS (0x10020C)).
          *
-         * The implementation of this opcode in general consists of two parts:
-         * 1) determination of the memory bus width
-         * 2) determination of how many of the card's RAM pads have ICs attached
+         * The implementation of this opcode in general consists of several
+         * parts:
          *
-         * 1) is done by a cunning combination of writes to offsets 0x1c and
-         * 0x3c in the framebuffer, and seeing whether the written values are
-         * read back correctly. This then affects bits 4-7 of NV_PFB_CFG0
+         * 1) Determination of memory type and density. Only necessary for
+         *    really old chipsets, the memory type reported by the strap bits
+         *    (0x101000) is assumed to be accurate on nv05 and newer.
          *
-         * 2) is done by a cunning combination of writes to an offset slightly
-         * less than the maximum memory reported by NV_PFB_CSTATUS, then seeing
-         * if the test pattern can be read back. This then affects bits 12-15 of
-         * NV_PFB_CFG0
+         * 2) Determination of the memory bus width. Usually done by a cunning
+         *    combination of writes to offsets 0x1c and 0x3c in the fb, and
+         *    seeing whether the written values are read back correctly.
          *
-         * In this context a "cunning combination" may include multiple reads
-         * and writes to varying locations, often alternating the test pattern
-         * and 0, doubtless to make sure buffers are filled, residual charges
-         * on tracks are removed etc.
+         *    Only necessary on nv0x-nv1x and nv34, on the other cards we can
+         *    trust the straps.
          *
-         * Unfortunately, the "cunning combination"s mentioned above, and the
-         * changes to the bits in NV_PFB_CFG0 differ with nearly every bios
-         * trace I have.
+         * 3) Determination of how many of the card's RAM pads have ICs
+         *    attached, usually done by a cunning combination of writes to an
+         *    offset slightly less than the maximum memory reported by
+         *    NV_PFB_CSTATUS, then seeing if the test pattern can be read back.
          *
-         * Therefore, we cheat and assume the value of NV_PFB_CFG0 with which
-         * we started was correct, and use that instead
+         * This appears to be a NOP on IGPs and NV4x or newer chipsets, both io
+         * logs of the VBIOS and kmmio traces of the binary driver POSTing the

+ * The OCTEON watchdog has a maximum timeout of 2^32 * io_clock.
+ * For most systems this is less than 10 seconds, so to allow for
+ * software to request longer watchdog heartbeats, we maintain software
+ * counters to count multiples of the base rate.  If the system locks
+ * up in such a manner that we can not run the software counters, the
+ * only result is a watchdog reset sooner than was requested.  But
+ * that is OK, because in this case userspace would likely not be able
+ * to do anything anyhow.
+ *
+ * The hardware watchdog interval we call the period.  The OCTEON
+ * watchdog goes through several stages, after the first period an
+ * irq is asserted, then if it is not reset, after the next period NMI
+ * is asserted, then after an additional period a chip wide soft reset.
+ * So for the software counters, we reset watchdog after each period
+ * and decrement the counter.  But for the last two periods we need to
+ * let the watchdog progress to the NMI stage so we disable the irq
+ * and let it proceed.  Once in the NMI, we print the register state
+ * to the serial port and then wait for the reset.
+ *
+ * A watchdog is maintained for each CPU in the system, that way if
+ * one CPU suffers a lockup, we also get a register dump and reset.
+ * The userspace ping resets the watchdog on all CPUs.
+ *
+ * Before userspace opens the watchdog device, we still run the
+ * watchdogs to catch any lockups that may be kernel related.
