drm/i915/selftests: Test i915_sw_fence/dma_fence interop

Browse source

Check that we can successfully wait upon a dma_fence using the
i915_sw_fence, including the optional timeout mechanism.

v2: Account for the rounding up of the timeout to the next second.
Unfortunately, the minimum delay is then 1 second.
