2012-01-11watchdog: hpwdt: Changes to handle NX secure bit in 32bit pathMingarelli, Thomas
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.

2011-07-26watchdog: sp805: Flush posted writes in enable/disable.Nick Bowler
There are no reads in these functions, so if MMIO writes are posted, the writes in enable/disable may not have completed by the time these functions return. If the functions run from different CPUs, it's in theory possible for the writes to be interleaved, which would be disastrous for this driver. At the very least, we need an mmiowb() before releasing the lock, but since it seems desirable for the watchdog timer to be actually stopped or reset when these functions return, read the lock register to force the writes out.

2011-07-26watchdog: sp805: Don't write 0 to the load value register.Nick Bowler
At least on the Versatile Express' V2M, calling wdt_disable followed by wdt_enable, for instance by running the following sequence: echo V > /dev/watchdog; echo V > /dev/watchdog results in an immediate reset. The wdt_disable function writes 0 to the load register; while the watchdog interrupts are disabled at this point, this special value is defined to trigger an interrupt immediately. It appears that in this instance, the reset happens when the interrupts are subsequently enabled by wdt_enable. Putting in a short delay after writing a new load value in wdt_enable solves the issue, but it seems cleaner to simply never write 0 to the load register at all: according to the hardware docs, writing 0 to the control register suffices to stop the counter, and the write of 0 to the load register is questionable anyway since this register resets to 0xffffffff.

2011-07-22watchdog: pc87413_wdt: Cleanup pc87413 watchdog driver to useJonathan McDowell
Inspired by Nat Gurumoorthy's recent patches for cleaning up the it87 drivers to use request_muxed_region for accessing the SuperIO area on these chips, and the fact I have a GPIO driver for the pc8741x basically ready for submission, here is a patch to cleanup the pc87413 watchdog driver to use request_muxed_region for accessing the SuperIO area. It also pulls out the details about the SWC IO area on initial driver load, and properly does a request_region for that area - there's no requirement to touch the SuperIO area after doing the initial watchdog enable and IO base retrieval. While I have hardware with a pc87413 on it it is not wired in a way that allows the watchdog to reboot the machine, so I have not been able to fully test these changes - I have checked that the driver correctly initialises itself still and requests the SWC io region ok.

2011-07-22watchdog: Use "request_muxed_region" in it87 watchdog driversNat Gurumoorthy
Changes the it87 watchdog drivers to use "request_muxed_region". Serialize access to the hardware by using "request_muxed_region" macro defined by Alan Cox. Call to this macro will hold off the requestor if the resource is currently busy. The use of the above macro makes it possible to get rid of spinlocks in it8712f_wdt.c and it87_wdt.c watchdog drivers. This also greatly simplifies the implementation of it87_wdt.c driver. "superio_enter" will return an error if call to "request_muxed_region" fails. Rest of the code change is to ripple an error return from superio_enter to the top level.

2011-07-16watchdog: fix hpwdt Kconfig regression in 3.0-rcOlaf Hering
Remove Kconfig regression caused by commit a4616153deae053b29a2b7dd9ec4b2a225accfc5 "watchdog: hpwdt: build hpwdt as module by default with NMI_DECODING enabled" With the above change applied, hpwdt will be enabled unconditionally by just entering the Watchdog subscreen in menuconfig. Since this driver is not essential to boot any box it should remain disabled until it gets manually enabled, just like all other drivers.
