Subject: drm/i915: More gt idling time with guc submission
Git-commit: 2528b396d5304a711d28f08047a8fe60daebc3ae
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
On i915_selftest@live@gt_timelines, we create many contexts in loop and
create and submit request and then destoy contexts. Destroying the context
needs to disable scheduling, wait for G2H, deregister context and wait
for G2H to destroy each context. Idling of the gt has to wait for all
this to complete which is taking ~3sec for this test.
Hence we are increasing the igt_flush_test's timeout for gt idling to
3Sec.
