Just a general question on > whether 30s timeout is too lax or just right? Thanks for review. I had just followed timeout time from existing pc8 tests for HASWELL/BROADWEL which was 30 second. It is not an engineering number. IMO i915 default auto-suspend ms time 10 sec (cat /sys/devices/pci0000\:00/0000\:00\:02.0/power/autosuspend_delay_ms) Considering above it may have some scope of optimization. Could you please provide some input on it. Thanks, Anshuman Gupta. > -Chris _______________________________________________ igt-dev mailing list igt-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/igt-dev
