[Intel-gfx] [PATCH i-g-t v4 0/5] Scheduler tests

[Derek Morton]

This patch set adds scheduler tests.
Patch 1 adds library code used by the tests. There are other tests under
development which are planned to reuse some of these libraries.
Patch 2 adds some basic tests, read dependency tests and write dependency tests.
Patch 3 Is the patch previously submitted by John Harrison to update
gem_ctx_param_basic with ioctls to set context priorities. It is included as
part of this patch set as Patch 6 & 7 are dependant on it.
Patch 4 adds subtests to check sheduler behaviour for batch buffers submitted at
differing priorities.
Patch 5 adds subtests to check priority starving behaviour.

v2: Updates for comments from  and Daniel Vetter
    Added tests requested by Joonas Lahtinen

v3: Removed the patch to update gem_has_ring() and updated the test to
    use BSD if there is 1 ring and BSD1 / BSD2 if there are two.

v4: Removed patch to make gem_has_ring() non static as another patch has already done so.
    Addressed more comments from Daniele Ceraolo Spurio
