* iTCO_wdt: fix TCO V1 timeout values and limitsPádraig Brady2010-05-25
| | | | | | | | | | | | | | For TCO V1 devices the programmed timeout was twice too long because the fact that the TCO V1 timer needs to count down twice before triggering the watchdog, wasn't accounted for. Also the timeout values in the module description and error message were clarified. And the _STS registers are 16 bit instead of 8 bit.

* [WATCHDOG] iTCO_wdt: clean up probe(), modify err msgNaga Chumbalkar2010-03-06
| | | | | | | | | | | | It's possible that the platform is not allowing reboot via TCO timer expiration. Also, differentiate between not finding a chipset that has TCO, and the case where TCO is present but the driver fails to initialize for some reason.

* [WATCHDOG] iTCO_wdt: fix memory corruption when RCBA is disabled by hardwareDenis V. Lunev2009-06-18
| | | | | | | | | | | | | | According to 9.1.33 on p.343 of ICH8.pdf RCBA can be disabled by hardware if bit 0 of RCBA register is not set. Perform correct check for this to prevent memory corruption under some virtual machines where this feature is disabled. Signed-off-by: Denis V.

| | | | | | | | | | bugzilla: #12363 commit 7cd5b08be3c489df11b559fef210b81133764ad4 added a second regression: some Dell's and Compaq's lockup on boot. So we revert most of the code. The ICH9 reboot issue remains in place and will need some more fixing... :-( Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* iTCO_wdt: fix typo when setting TCO_EN bitLinus Torvalds2008-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The code used '&= 0x00002000' when it tried to set the TCO_EN bit, which obviously didn't set that bit at all, but instead just reset all the other bits in the SMI_EN register. This bug seemingly caused various random behavior, with Frans Pop reporting that X.org just silently hung at startup and Rafael Wysocki reports the fan spinning with full speed. See http://lkml.org/lkml/2008/12/3/178 http://bugzilla.kernel.org/show_bug.cgi?id=12162 The problem seems to have been triggered by "[WATCHDOG] iTCO_wdt : problem with rebooting on new ICH9 based motherboards" (commit 7cd5b08be3c489df11b559fef210b81133764ad4), but the bogus code existed before that too (in the "supermicro_old_pre_stop()" function), it just apparently never showed up due to different logic. In that commit the broken code got moved around and now gets executed much more. Reported-by: Rafael J.

* [WATCHDOG] iTCO_wdt : correct status clearingWim Van Sebroeck2008-11-21
| | | | | | | | | | | The iTCO_wdt code was not clearing the correct bits. It now clears the timeout status bit and then the SECOND_TO_STS bit and then the BOOT_STS bit. Note: we should first clear the SECOND_TO_STS bit before clearing the BOOT_STS bit. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* [WATCHDOG] iTCO_wdt : problem with rebooting on new ICH9 based motherboardsWim Van Sebroeck2008-11-21
| | | | | | | | | | | | Bugzilla #9868: On Intel motherboards with the ICH9 based I/O controllers (Like DP35DP and DG33FB) the iTCO timer counts but it doesn't reboot the system after the counter expires. This patch fixes this by moving the enabling & disabling of the TCO_EN bit in the SMI_EN register into the start and stop code. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

* [WATCHDOG] Coding style - Indentation - part 2Wim Van Sebroeck2008-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | This brings the watchdog drivers into line with coding style. This patch takes cares of the indentation as described in chapter 1. Main changes: * Re-structure the ioctl switch call for all drivers as follows: switch (cmd) { case WDIOC_GETSUPPORT: case WDIOC_GETSTATUS: case WDIOC_GETBOOTSTATUS: case WDIOC_GETTEMP: case WDIOC_SETOPTIONS: case WDIOC_KEEPALIVE: case WDIOC_SETTIMEOUT: case WDIOC_GETTIMEOUT: case WDIOC_GETTIMELEFT: default: } This to make the migration from the drivers to the uniform watchdog device driver easier in the future.
