  • e56d48e92   watchdog: imx_sc_wdt: Fix reboot on crash ... Browse Code »

    Currently when running the samples/watchdog/watchdog-simple.c
    application and forcing a kernel crash by doing:

    # ./watchdog-simple &
    # echo c > /proc/sysrq-trigger

    The system does not reboot as expected.

    Fix it by calling imx_sc_wdt_set_timeout() to configure the i.MX8QXP
    watchdog with a proper timeout.

    An error message is already displayed by watchdog_register_device()
    when failed, so no need to have error log again for failure of
    calling devm_watchdog_register_device().

    i.MX system controller watchdog can support pretimeout IRQ
    via general SCU MU IRQ, it depends on IMX_SCU and driver MUST
    be probed after SCU IPC ready, then enable corresponding SCU
    IRQ group and register SCU IRQ notifier, when watchdog pretimeout
    IRQ fires, SCU MU IRQ will be handled and watchdog pretimeout
    notifier will be called to handle the event.

    Introduce local variable 'struct device *dev' and use it instead of
    dereferencing it repeatedly.

    The conversion was done automatically with coccinelle using the
    following semantic patches. The semantic patches and the scripts

    i.MX8QXP is an ARMv8 SoC which has a Cortex-M4 system controller
    inside, the system controller is in charge of controlling power,
    clock and watchdog etc..

    This patch adds i.MX system controller watchdog driver support,
    watchdog operation needs to be done in secure EL3 mode via
    ARM-Trusted-Firmware, using SMC call, CPU will trap into
    ARM-Trusted-Firmware and then it will request system controller
    to do watchdog operation via IPC.
