    clocksource/drivers/arm_arch_timer: Control the evtstrm via the cmdline · 46fd5c6b
    Will Deacon authored
    Disabling the eventstream can be useful for both remotely debugging a
    deployed production system and development of code using WFE-based
    polling loops. Whilst this can currently be controlled via a Kconfig
    option (CONFIG_ARM_ARCH_TIMER_EVTSTREAM), it's often desirable to toggle
    the feature on the command line, so this patch adds a new command-line
    option ("clocksource.arm_arch_timer.evtstrm") to do just that. The
    default behaviour is determined based on CONFIG_ARM_ARCH_TIMER_EVTSTREAM.
