| * watchdog: booke_wdt: clean up status messagesTimur Tabi2011-03-151-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Improve the status messages that are displayed during some operations of the PowerPC watchdog timer driver. When the watchdog is enabled, the timeout is displayed as a number of seconds, instead of an obscure "period". The "period" is the position of a bit in a 64-bit timer register. The higher the value, the quicker the watchdog timeout occurs. Some people chose a high "period" value for the timer and get confused as to why the board resets within a few seconds. Messages displayed during open and close are now debug messages, so that they don't clutter the console by default. Finally, printk() is replaced with the pr_xxx() equivalent.

| | | | | | | | | | | | | | | | | | | | | | | | While the hypervisor change adding SCHEDOP_watchdog support included a daemon to make use of the new functionality, having a kernel driver for /dev/watchdog so that user space code doesn't need to distinguish non-Xen and Xen seems to be preferable.

| * watchdog: Intel SCU Watchdog Timer Driver for Moorestown and Medfield platforms.Donald Johnson2011-03-154-0/+649
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This submission includes: - Fix to intel_scu_write() to start watchdog timer the on the first write, and refresh on subsequent writes. This enables Open, write, write, ... usage model. - Moves boot parameter checks from intel_scu_open() to intel_scu_watchdog_init(), so driver init will fail if these parameters are out of bounds. - Adds check for whether process waiting in wait_event_interruptible() received a signal while it was waiting. - Other small error handling changes. Removed the read() method for now as that wass a non-standard behaviour.

Unfortunately, they trigger on events like DIE_NMI and DIE_NMI_IPI, which depending on when they registered may collide with other handlers that have the ability to determine if the NMI is theirs or not. The function unknown_nmi_error() makes one last effort to walk the die_chain when no one else has claimed the NMI before spitting out messages that the NMI is unknown. This is a better spot for these devices to execute any code without colliding with the other handlers. The two drivers modified are only compiled on x86 arches I believe, so they shouldn't be affected by other arches that may not have DIE_NMIUNKNOWN defined.

| * | | x86, nmi_watchdog: Remove ARCH_HAS_NMI_WATCHDOG and rely on ↵Don Zickus2010-12-221-2/+2

This shift has caused a whole bunch of compile problems under different config options. I attempt to simplify things with the patch below. In order to simplify things, I had to come to terms with the meaning of two terms ARCH_HAS_NMI_WATCHDOG and CONFIG_HARDLOCKUP_DETECTOR. Basically they mean the same thing, the former on a local level and the latter on a global level. With the old x86 nmi watchdog gone, there is no need to rely on defining the ARCH_HAS_NMI_WATCHDOG variable because it doesn't make sense any more. x86 will now use the global implementation. The changes below do a few things. First it changes the few places that relied on ARCH_HAS_NMI_WATCHDOG to use CONFIG_X86_LOCAL_APIC (the former was an alias for the latter anyway, so nothing unusual here). Those pieces of code were relying more on local apic functionality the nmi watchdog functionality, so the change should make sense. Second, I removed the x86 implementation of touch_nmi_watchdog(). It isn't need now, instead x86 will rely on kernel/watchdog.c's implementation. Third, I removed the #define ARCH_HAS_NMI_WATCHDOG itself from x86. And tweaked the include/linux/nmi.h file to tell users to look for an externally defined touch_nmi_watchdog in the case of ARCH_HAS_NMI_WATCHDOG _or_ CONFIG_HARDLOCKUP_DETECTOR. This changes removes some of the ugliness in that file. Finally, I added a Kconfig dependency for CONFIG_HARDLOCKUP_DETECTOR that said you can't have ARCH_HAS_NMI_WATCHDOG _and_ CONFIG_HARDLOCKUP_DETECTOR. You can only have one nmi_watchdog. Tested with ARCH=i386: allnoconfig, defconfig, allyesconfig, (various broken configs) ARCH=x86_64: allnoconfig, defconfig, allyesconfig, (various broken configs) Hopefully, after this patch I won't get any more compile broken emails. :-) v3: changed a couple of 'linux/nmi.h' -> 'asm/nmi.h' to pick-up correct function prototypes when CONFIG_HARDLOCKUP_DETECTOR is not set.
