2010-08-05WATCHDOG: Add watchdog driver for OCTEON SOCsDavid Daney1-0/+2
The OCTEON is a MIPS64 based SOC family with an on chip watchdog unit. The driver is split into two source files one for the C code and one for assembly. Assembly is needed to handle the NMI and then print the machine state before the reboot is triggered.

2009-06-20[WATCHDOG] add bcm47xx watchdog drivermatthieu castet1-0/+1
This add watchdog driver for broadcom 47xx device. It uses the ssb subsytem to access embeded watchdog device. Because the watchdog timeout is very short (about 2s), a soft timer is used to increase the watchdog period. Note : A patch for exporting the ssb_watchdog_timer_set will be submitted on next linux-mips merge. Without this patch it can't be build as a module.

GE Fanuc SBC610 Support for the FPGA based watchdog timer as found on GE Fanuc's SBC310, SBC610 and PPC9A Single Board Computers. This patch adds support for the watchdog timer found in one of the devices FPGAs. There are two identical watchdog timers at different offsets in the above mentioned boards, this driver is capable of supporting one of them. The watchdog timers are also capable of generating interrupts at a user-configurable threshold, though support for this operation is currently not supported by the driver.

2008-07-24remove the v850 portAdrian Bunk1-2/+0
Trying to compile the v850 port brings many compile errors, one of them exists since at least kernel 2.6.19. There also seems to be noone willing to bring this port back into a usable state. This patch therefore removes the v850 port. If anyone ever decides to revive the v850 port the code will still be available from older kernels, and it wouldn't be impossible for the port to reenter the kernel if it would become actively maintained again.

Hp is providing a Hardware WatchDog Timer driver that will only work with the specific HW Timer located in the HP ProLiant iLO 2 ASIC. The iLO 2 HW Timer will generate a Non-maskable Interrupt (NMI) 9 seconds before physically resetting the server, by removing power, so that the event can be logged to the HP Integrated Management Log (IML), a Non-Volatile Random Access Memory (NVRAM). The logging of the event is performed using the HP ProLiant ROM via an Industry Standard access known as a BIOS Service Directory Entry.
