[PATCH] drm/i915/gt: Always reschedule the new heartbeat

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In order to better respond to new heartbeat intervals given via sysfs,
always reprogramme an active heartbeat upon change (i.e. use
mod_delayed_work to reschedule rather than queue_delayed_work which
ignores an already active work.)
