Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

* Written for the Linux Kernel, and GPLed by Ken Hollis
*
* 960107 Added request_region routines, modulized the whole thing.
* 960108 Fixed end-of-file pointer (Thanks to Dan Hollis), added
* WD_TIMEOUT define.
* 960216 Added eof marker on the file, and changed verbose messages.
* 960716 Made functional and cosmetic changes to the source for
* inclusion in Linux 2.0.x kernels, thanks to Alan Cox.
* 960717 Removed read/seek routines, replaced with ioctl. Also, added
* check_region command due to Alan's suggestion.
* 960821 Made changes to compile in newer 2.0.x kernels. Added
* "cold reboot sense" entry.
* 960825 Made a few changes to code, deleted some defines and made
* typedefs to replace them. Made heartbeat reset only available
* via ioctl, and removed the write routine.
* 960828 Added new items for PC Watchdog Rev.C card.
* 960829 Changed around all of the IOCTLs, added new features,
* added watchdog disable/re-enable routines. Added firmware
* version reporting. Added read routine for temperature.
* Removed some extra defines, added an autodetect Revision
* routine.
* 961006 Revised some documentation, fixed some cosmetic bugs. Made
* drivers to panic the system if it's overheating at bootup.
* 961118 Changed some verbiage on some of the output, tidied up
* code bits, and added compatibility to 2.1.x.
* 970912 Enabled board on open and disable on close.
* 971107 Took account of recent VFS changes (broke read).
* 971210 Disable board on initialisation in case board already ticking.
* 971222 Changed open/close for temperature handling
* Michael Meskes <meskes@debian.org>.
* 980112 Used minor numbers from include/linux/miscdevice.h
* 990403 Clear reset status after reading control status register in
* pcwd_showprevstate(). [Marc Boucher <marc@mbsi.ca>]
* 990605 Made changes to code to support Firmware 1.22a, added
* fairly useless proc entry.
* 990610 removed said useless proc code for the merge <alan>
* 000403 Removed last traces of proc code. <davej>
* 011214 Added nowayout module option to override CONFIG_WATCHDOG_NOWAYOUT <Matt_Domsch@dell.com>

[WATCHDOG] pcwd_usb.c - get heartbeat from dip switches The PCWD cards normally use the heartbeat that is set via the dip-switches of the card. There are only 3 switches, thus 8 combinations that each have a certain heartbeat. The card can however be programmed with a heartbeat from 1 till 65535 seconds. This is what our driver does: it programs the heartbeat on the card. There are however a lot of people that don't know that we set the heartbeat of the watchdog card to the value provided by the heartbeat module parameter. Instead they think that the heartbeat value is the same as set by the dip-switches. This patch changes the driver so that at startup you can take the heartbeat from the dip-switches. You do this by setting the heartbeat module parameter to 0. This patch also makes this the default behaviour. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

[WATCHDOG] pcwd_usb.c - get heartbeat from dip switches The PCWD cards normally use the heartbeat that is set via the dip-switches of the card. There are only 3 switches, thus 8 combinations that each have a certain heartbeat. The card can however be programmed with a heartbeat from 1 till 65535 seconds. This is what our driver does: it programs the heartbeat on the card. There are however a lot of people that don't know that we set the heartbeat of the watchdog card to the value provided by the heartbeat module parameter. Instead they think that the heartbeat value is the same as set by the dip-switches. This patch changes the driver so that at startup you can take the heartbeat from the dip-switches. You do this by setting the heartbeat module parameter to 0. This patch also makes this the default behaviour. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
