watchdog: hpwdt: Changes to handle NX secure bit in 32bit path

2012-01-06T22:17:22Z

commit e67d668e147c3b4fec638c9e0ace04319f5ceccd upstream. This patch makes use of the set_memory_x() kernel API in order to make necessary BIOS calls to source NMIs. This is needed for SLES11 SP2 and the latest upstream kernel as it appears the NX Execute Disable has grown in its control.

watchdog: lantiq: fix watchdogs timeout handling

2011-09-20T12:28:24Z

The enable function was using the global timeout variable for local operations. This resulted in the value of the global variable being corrupted, thus breaking the code.

watchdog: hpwdt: prevent multiple "NMI occurred" messages

2011-09-20T12:24:54Z

On platforms with no iCRU support don't print two, (possibly conflicting), "NMI occurred" messages when the firmware is unable to source the NMI. Please note that one of the enhancements to the v1.3.0 hpwdt driver is to panic and allow KDUMP to succeed even on NMIs that are unknown to the platform firmware.

watchdog: WatchDog Timer Driver Core - use passed watchdog_device

2011-09-20T12:22:28Z

Use the passed watchdog_device instead of the static global variable when testing and setting the status in watchdog_ping, watchdog_start, and watchdog_stop. Note that the callers of these functions are actually passing the static global variable. Signed-off-by: H Hartley Sweeten Signed-off-by: Wim Van Sebroeck

watchdog: Cleanup WATCHDOG_CORE help text

2011-08-02T08:23:07Z

The newly added WATCHDOG_CORE option is a bool, but the help text suggests it can be built as a module. Fix it up. Signed-off-by: Josh Boyer Signed-off-by: Wim Van Sebroeck

watchdog: Fix POST failure on ASUS P5N32-E SLI and similar boards

2011-08-02T08:22:54Z

At present the module does not unset the NO_REBOOT bit upon shutdown, this causes the BIOS to fail the POST once and reset. During the next boot it displays the following error message: ***** Warning: System BOOT Fail ***** Your system last boot fail or POST interrupted. Please enter setup to load default and reboot again. Press F1 to continue, DEL to enter SETUP With this patch the NO_REBOOT flag will be unset on shutdown and thus stop this failure from occurring. Tested on 'ASUS P5N32-E SLI with BIOS revision 1801' and 'ASUS P5N32-E SLI PLUS with BIOS revision 1502'. Signed-off-by: Mart Gerrits Signed-off-by: Wim Van Sebroeck

watchdog: shwdt: fix usage of mod_timer

2011-08-02T08:22:49Z

Fix the usage of mod_timer() and make the driver usable. mod_timer() must be called with an absolute timeout in jiffies. The old implementation used a relative timeout thus the hardware watchdog was never triggered.

watchdog: WatchDog Timer Driver Core - Add minimum and max timeout

2011-07-28T08:01:18Z

Add min_timeout (minimum timeout) and max_timeout values so that the framework can check if the new timeout value is between the minimum and maximum timeout values. If both values are 0, then the framework will leave the check for the watchdog device driver itself.
