Apparently nobody else likes testing and debugging GEM coherency issues.
However, this also means that QA is skipping these vital tests. Split
out a set of canaries into igt/gem_concurrent_blit and keep the rest in
igt/gem_concurrent_all.

New test pm_sseu is intended for any subtest related to the
slice/subslice/EU power gating feature. The sole initial subtest,
'full-enable', confirms that the slice/subslice/EU state is at
full enablement when the render engine is active. Starting with
Gen9 SKL, the render power gating feature can leave SSEU in a
partially enabled state upon resumption of render work unless
explicit action is taken.
v2: Add test description and apply recommendations of igt.cocci
(Thomas Wood).
v3: Skip instead of fail if debugfs entry i915_sseu_status is not

The gem_tiled_fence_blits test tends to get oom killed
on low memory (< 4GB) Android systems. This is because the
test tries to allocate (sysinfo.totalram * 9 / 10) in
buffer objects and the remaining 10% of memory is not
always enough for the Android system.
As with a similar issue with gem_render_linear_blits,
this problem is resolved by splitting into subtests.
A "basic" subtest uses minimal memory buffers to test
the basic operation, and a "normal" subtest which is
skipped if there is insufficient memory.
I also took the opportunity to cull some numeric literals.

Tests should positively check for crc matches, not for mismatches.
Enforce this by only exposing and igt_assert function for comparing

to do functional tests add FIXME comments that some reference crc
values are missing.

Because of hash collisions tests should only ever compare crc
checksums for equality. Checking for inequality can result in random
failures.
To ensure this only expose and igt_assert function and use that.
Follow-up patches will rework the code for tests which don't follow
this requirement and try to compare for CRC inequality.

The choice is to either move the igt_require from the buffer allocation
(and allow the allocation to fail) inside the igt_fixture, or move the
buffer allocation to the subtest. Moving it to the subtest has the
advantage of ensuring that every test has the same initial state (no
chance of leaking state across tests) and speeding up running a single
subtest.
Note this is necessary in order to run igt/gem_concurrent_blit on older
kernels, otherwise the requirement for mmap(wc) causes us to skip the
majority of tests.

i915 was using the main atomic 'disable plane' to turn off sprite planes
during a CRTC disable. This was problematic because it modified the
plane state, preventing us from recovering the original state later.
One such case was that during a DPMS OFF followed by a DPMS ON, any
sprite planes would not be restored properly.
Let's add a test that toggles DPMS off and on and ensures that the CRC
remains the same (i.e., planes are successfully restored unchanged).

test tries to allocate (sysinfo.totalram * 9 / 10) in
buffer objects and the remaining 10% of memory is not

A similar issue with gem_render_linear_blits was resolved
by creating several subtests. A "basic" subtest that uses
minimal memory buffers to test the basic operation, and
two stress tests which are skipped if there is insufficient
memory. The first stress test uses more memory than the
graphics apperture and the second uses enough to ensure
that swap space is used (if present).
This patch makes the same changes to gem_render_tiled_blits.

After a discussion with Chris Wilson I have split this
test into a "basic" and an "apperture-thrash" subtest,
in the same way as gem_linear_blits. The basic test
uses just two buffer objects and the apperture-thrash
test is skipped if there is insuffiecient memory.
v2: Following comment from Chris Wilson:
a) Remove the command line option for count.
b) Add a third subtest to ensure swap is tested

disabling bit-mangling. Since we don't want to reimplement everything
the Kernel does, let's just accept the fact that some VGA outputs
won't be properly detected.
