Currently tests that use igt_simple_main will simply call
"exit()" if they pass, making it difficult to ensure that
any required cleanup is done. At present this is not an
issue, but it will be when I submit a patch to turn off the
lowmemorykiller for all tests.

In order to exercise https://bugs.freedesktop.org/show_bug.cgi?id=84207
we need to interrupt the mmu_notifier_register with a signal. This is
likely to be quite difficult, but let's just try running the
create-destroy test in an interruptible loop for 5s.

Due to the nature of the test, we can be reasonably sure that it is
either all copied or not. So we can sacrificing testing the entire
buffer for the expected value in order to speed up the test by only
testing along the diagonal.

Since the last patched value does not match the presumed relocation
value we submit to the kernel, it occasionally makes mistakes. Also note
that the libdrm interface makes the same presumptive mistake, and would
easily be broken by a threaded environment.

kms_psr_sink_crc check psr activity, residency and exit for screen updates.
So this test is useless.
Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
Black screen is forbidden on this test. So let's fail if sink crc shows
it is back.
Also there are many cases where we know for shure it should be all green,
so let's check for them.
Instead of checking colors we could print with sw using cairo and check if we
have identical crc like cursor testcases. However with PSR the chance of artifacts
is low and chance of getting blank screen or unchanged screen is high. So even drawing
on sw and comparing both CRCs we can have the same result. However the risk is that
screen never changed. So the safest way is to compare if screen changed and check
the green color when we know it should be green or not green.
v2: Hardcoded green was simply wrong because green CRC can change depending
on display.Split R, G and B on CRC and bitewise them with mask to verify
it is green.

The test relies on having to wait upon the GPU at some point and so
simulating a missed interrupt. If there is insufficient load on the GPU,
we can complete the task before we even wait.
