Subject: [igt-dev] [PATCH i-g-t] tests/i915_pm_lpsp: Add igt_wait to test lpsp
Date: Thu, 16 Jul 2020 19:45:57 +0530	[thread overview]
Message-ID: <20200716141557.15909-1-anshuman.gupta@intel.com> (raw)

Sometimes LPSP test may fail due to HOTPLUG events,
which initiates AUX transaction in order to detect a Connector
status, these ongoing AUX transaction may fail the LPSP igt test.
Adding a igt_wait will avoid such failures.
Some eDP panel may have power_cycle_delay of 600ms,
therefore 1sec delay is safer.
