2017-11-02lib/igt_debugfs: Use fstat instead of open for testing CRC support.Maarten Lankhorst
commit 8038e09be5a3ac06 ("drm/crc: Only open CRC on atomic drivers when the CRTC is active.") rejects opens on the CRC when the CRTC is not configured. Use fstat instead to check this file exists, so we don't accidentally rely on the legacy CRC path.

2017-10-26igt/gem_exec_latency: Wire up an interloper for preemptionChris Wilson
For measuring the cost of preemption, inject a low priority spinner between the two measurements; the difference between the preemption and the normal dispatch includes both the cost of the spinner dispatch and of preempting it. Close enough for us to estimate the cost of preemption, though we don't measure the cost of preemption on the local ring!

2017-10-25igt/gem_fd_exhaustion: Remove stale assertChris Wilson
__gem_create() doesn't touch the outparam *handle on failure, so we can no longer assert that it zero. This is reasonable to remove as it is just testing the library itself and not the kernel, so no loss in coverage. We already had to remove the false assertion that gem_create() must fail following fd exhaustion (as we can not prevent the kernel from freeing VFS fdspace in between calls). The last remaining change is that we do no need to rely on an external path for open() as dup() will do the job of exhausting the fdtable.

2017-10-25lib/gt: Always eat the unwanted error stateChris Wilson
We only suppress the error state from the context, iff we trigger the GPU reset by hangcheck (igt_hang_ring). If we trigger an immediate reset via igt_force_gpu_reset(), we will populate the error-state but not free it because we thought we have it suppressed by the context parameter. Always eat the error after we expect a GPU reset and have not specified that we want to keep it. The side-effect of keeping the error-state around after we deliberately created it is that subsequent GPU hangs are not prominently recorded, as the kernel believes they are secondary hangs (and we only announce the first).

2017-10-24tests/kms_atomic_transition: Do not update unbound planes.Maarten Lankhorst
kms_atomic_transition was updating already disabled planes and committing them nonblockingly. This results in sporadic -EBUSY failures because planes that are unbound have their own timeline. The solution is not unbinding already unbound planes, making the test pass. There was also a related kernel bug causing failures in the same way, but that is now fixed. While at it, only check for fd completion in the nonblocking case, in the blocking case it's theoretically possible the commit completes before we check the that the commit didn't complete, most probably when the test is run in a debugger.
