  • 47bfd0581   watchdog: Octeon: Mark octeon_wdt interrupt as IRQF_NO_THREAD ... Browse Code »

    This is to exclude it from force threading to allow RT patch set to work.

    The watchdog timers are per-CPU and the addresses of register that reset
    the timer are calculated based on the current CPU. Therefore we cannot
    allow it to run on a thread on a different CPU. Also we only do a
    single register write, which is much faster than scheduling a handler
    thread.

    And while on this line remove IRQF_DISABLED as this flag is a NOP.

  • 468ffde46   WATCHDOG: octeon-wdt: Use I/O clock rate for timing calculations. ... Browse Code »

    The creation of the I/O clock domain requires some adjustments. Since
    the watchdog counters are clocked by the I/O clock, use its rate for
    timing calculations.

    Add missing #inclusions of to a whole bunch of files that should
    really include it. Note that this can replace #inclusions of .

    This is required for the patch to sort out irqflags handling function naming to
    compile on MIPS.

    The problem is that these files require access to things like setup_irq() -
    which isn't available by #including

  • 4c076fb41   WATCHDOG: Add watchdog driver for OCTEON SOCs ... Browse Code »

    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.
