Chris Wilson b79029b2e8 drm/i915/gt: Make timeslice duration configurable ... Execlists uses a scheduling quantum (a timeslice) to alternate execution between ready-to-run contexts of equal priority. This ensures that all users (though only if they of equal importance) have the opportunity to run and prevents livelocks where contexts may have implicit ordering due to userspace semaphores. However, not all workloads necessarily benefit from timeslicing and in the extreme some sysadmin may want to disable or reduce the timeslicing granularity. The timeslicing mechanism can be compiled out^W^W disabled (but should DCE!) with ./scripts/config --set-val DRM_I915_TIMESLICE_DURATION 0 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Reviewed-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191029091632.26281-1-chris@chris-wilson.co.uk		2019-10-29 16:23:55 +00:00
