Now that we started packaging all parameters in one handy struct, pass
them everywhere. This allows us to pass along requirements so that we
can perform the checks inside each indvidual subtest and so not anger
the igt gods.

For the long running tests probing error conditions, throwing in the
signal interruptions is a good idea.
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
Becareful in case we try and eat the error state whilst interrupts are
being sent and repeat the write() until we finish uninterrupted.

With large apertures we need to use uint64_t for

paved way for this but forgot to change the subtest parameters.

So far we have had only two commit styles, COMMIT_LEGACY
and COMMIT_UNIVERSAL. This patch adds another commit style
COMMIT_ATOMIC which makes use of drmModeAtomicCommit()
v2: (Marius)
i)Set CRTC_ID to zero while disabling plane
ii)Modified the log message in igt_atomic_prepare_plane_commit
https://patchwork.freedesktop.org/patch/71945/
v3: (Marius)Set FB_ID to zero while disabling plane
https://patchwork.freedesktop.org/patch/72179/
v4: (Maarten) Corrected the typo in commit message
https://patchwork.freedesktop.org/patch/72598/
v5: Added check for DRM_CLIENT_CAP_ATOMIC in igt_display_init
(Marius)
i)Removed unused props from igt_display_init
ii)Removed unused ret. Changed function to void
iii)Declare the variable before checking if we have
DRM_CLIENT_CAP_ATOMIC.
https://patchwork.freedesktop.org/patch/73505/
v6: (Jani) Corrected typo in commit message
v7: Added is_atomic check for DRM_CLIENT_CAP_ATOMIC in
igt_display_init and igt_atomic_commit
v8: (Matthew Auld) Replaced for loops by for_each_connected_output and
for_each_plane_on_pipe
(Lionel) Populate properties only if the value has changed
Remove the resetting of values in disable case
Note : I've used Maarten's diff patch
v9: (Lionel) Added resetting of rotation property
v10: (Marius) Modified the macro declaration to avoid shadow declaration
warning, also removed one unused variable

A more complicated store variant to stress inter-engine dependencies
(i.e. semaphores and sync). We write a control value from one batch into
the next and then execute it. This is repeated a few times with each
execution happening on a different engine (so the kernel has to
serialise operations between engines) until we finally write the value
out into our scratch buffer where we can check the result, just like a
Chinese whisper.

Since clock_gettime() should be a fixed overhead that adds to the

Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
In order to keep the latency as low as possible for the idle load, we
need to keep the CPU awake. Otherwise we end up with the busy workload
having lower latency than the idle workload!

Also useful to know how much worse than baseline the latency is when the
gem load is applied. For slower systems, presenting in nanoseconds makes
it hard to read, so switch to microseconds for output.
