[Intel-gfx] [PATCH i-g-t] syncobj: Add some wait and reset tests (v2)
Jason Ekstrand
jason at jlekstrand.net
Wed Aug 9 17:25:08 UTC 2017
This adds both trivial error-checking tests as well as more complex
tests which actually test whether or not waits do what they're supposed
to do. They only currently work on i915 but it should be simple to hook
them up for other drivers by simply implementing the little function
pointer hook provided at the top for triggering a syncobj.
v2:
- Actually add the reset tests.
