In a project for my company I've needed to use the watchdog device in a PCM-5335 SBC from AAEON. The watchdog timer is from a Winbond's SuperIO chip, the W83977F. I've made this driver based on two others already on the kernel tree, the w83877f_wdt and the wdt977.

The device/watchdog has a fixed timeout/heartbeat. So we don't support the WDIOC_SETTIMEOUT ioctl call and we also may not set the WDIOF_SETTIMEOUT flag. Cc: Andrey Panin <pazke@donpac.ru> Cc: Andrew Morton <akpm@osdl.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

the attached patch moves the content of drivers/char/watchdog/i6300.h into drivers/char/watchdog/i6300.c, since it is the only file using the defines there is no real reason to have a separate header. Also cleaned up the comments a bit and added myself to the copyright holders.

In i6300esb.c watchdog card driver were 2 bugs (misused pc_match_device and pci_dev_put wasn't called in one error case) and one little cleanup was done (long line was converted to a shorter one with using built-in macro).

This patch sets the WDT_ENABLE bit of the Lock Register to enable the watchdog and WDT_LOCK bit only if nowayout is set. The old code always sets the WDT_LOCK bit of watchdog timer for Intel 6300ESB chipset. So, we end up locking the watchdog instead of enabling it.

I wrote earlier to the list[1] asking for a driver for the watchdog included in the 6300ESB chipset. I got a 2.4 driver via private email from Ross Biro which I've changed into what I hope resembles a 2.6 driver (which was done by looking a lot at the watchdog drivers already in the 2.6 tree). I've attached the result, and I'm hoping to get some feedback on the coding as a first step. I can't actually test it on the hardware right now as I won't have physical access until April. So my own tests have been limited to "compiles-without-warnings" and "can-be-insmodded-in-other-machine-without-oops".

There was another case where sb_size wasn't being set, so instead do the sensible thing and set if when filling in the content of a superblock.

[PATCH] md: make sure the new 'sb_size' is set properly device added without pre-existing superblock. There are two ways to add devices to an md/raid array. It can have superblock written to it, and then given to the md driver, which will read the superblock (the new way) or md can be told (through SET_ARRAY_INFO) the shape of the array, and the told about individual drives, and md will create the required superblock (the old way). The newly introduced sb_size was only set for drives being added the new way, not the old ways.

On reflection, a better default location for hot-adding bitmaps with version-1 superblocks is immediately after the superblock. There might not be much room there, but there is usually atleast 3k, and that is a good start.

Most awkward part of this is delaying write requests until bitmap updates have been flushed. To achieve this, we have a sequence number (seq_flush) which is incremented each time the raid5 is unplugged. If the raid thread notices that this has changed, it flushes bitmap changes, and assigned the value of seq_flush to seq_write. When a write request arrives, it is given the number from seq_write, and that write request may not complete until seq_flush is larger than the saved seq number. We have a new queue for storing stripes which are waiting for a bitmap flush and an extra flag for stripes to record if the write was 'degraded' and so should not clear the a bit in the bitmap.

version-1 superblocks are not (normally) 4K long, and can be of variable size. Writing the full 4K can cause corruption (but only in non-default configurations). With this patch the super-block-flavour can choose a size to read, and set a size to write based on what it finds.

It is possibly (and occasionally useful) to have a raid1 without persistent superblocks. The code in add_new_disk for adding a device to such an array always tries to read a superblock. This will obviously fail. So do the appropriate test and call md_import_device with appropriate args.

linear currently uses division by the size of the smallest componenet device to find which device a request goes to. If that smallest device is larger than 2 terabytes, then the division will not work on some systems. So we introduce a pre-shift, and take care not to make the hash table too large, much like the code in raid0. Also get rid of conf->nr_zones, which is not needed.

If a device is flagged 'WriteMostly' and the array has a bitmap, and the bitmap superblock indicates that write_behind is allowed, then write_behind is enabled for WriteMostly devices. Write requests will be acknowledges as complete to the caller (via b_end_io) when all non-WriteMostly devices have completed the write, but will not be cleared from the bitmap until all devices complete. This requires memory allocation to make a local copy of the data being written. If there is insufficient memory, then we fall-back on normal write semantics.
