[igt-dev] [PATCH i-g-t v2] tests/gem_watchdog: GPU engine reset

[Carlos Santa]

This IGT test complements the Gen8+ engine-reset feature patch
series aka Timeout Detection and Recovery (TDR) that Michel Thierry
submitted here: https://patchwork.freedesktop.org/series/21868/, specifically
the Watchdog timer feature of the original that is still not in
upstream.
	
There are several pieces that are required in order to
get (TDR) Watchdog timer in upstream:
	
(1) having a proper IGT set of tests that can exercise the feature
(2) but more imporantly, having a qualified user space client such
as a media driver that can trigger the watchdog timer after submitting
GPU work that could reset the media engine after encountering a
hung engine for example.
	
This IGT test is to cover requirement (1) above.
