Chris Wilson ee73e2795b drm/i915/tgl: Disable preemption while being debugged ... We see failures where the context continues executing past a preemption event, eventually leading to situations where a request has executed before we have event submitted it to HW! It seems like tgl is ignoring our RING_TAIL updates, but more likely is that there is a missing update required for our semaphore waits around preemption. v2: And disable internal semaphore usage Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Acked-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190912132313.12751-1-chris@chris-wilson.co.uk		2019-09-12 20:45:23 +01:00
