It is to check whether media pipeline on render ring works. Codes
are copied and modified from the rendercopy case which uses 3D pipeline.
However media pipeline is simpler than 3D pipeline and there is few changes
between gen6,gen7 and gen8

It didn't pan out at all since atm we don't evict context objects. But
maybe it's useful for when that happens.
v2: Actually test eviction. Took a while to figure that one out.
And indeed the testcase now fails because we don't evict the previous
context as we should.

kms_fbc_crc will perform various write operations to the scanout buffer
whilc FBC is enabled. CRC checks will be used to make sure the
modifcations to scanout buffer are detected.
The operations include:
- page flip
- GTT mmap
- CPU mmap
- blit
- rendercopy
- context switch + rendercopy
- combination of a page flip and each operation listed above
v2: Use gem_sw_finish instead of drmModeDirtyFB after CPU access

Instead of creating a new FB every time we need one, create a cache of
FBs and reuse whenever possible. That means we'll create at most two
FBs, and reuse them hundreds and hundreds of times.
The kmstest_paint_test_pattern function takes about 1-2 seconds to
run, and we'll avoid it whenever we reuse the FB.
This makes the time taken to run the modeset-lpsp-stress subtest go
from 2:29 to 1:29.
A full "time ./pm_pc8 --quick" goes from 8:14 to 6:27.

If we want to actually reach PC8+ states, we need to properly
configure all the devices on the system to allow this. This function
will try to setup the things we know we need, but won't scream in case
anything fails: we don't know which devices are present on your
machine, so we can't really expect anything, just try to help with the
more common problems.
Another reason for this commit is that I got tired of having to
readjust the runtime PM policies every time I reboot my machine.

It's not executed by default, and it's completely relying on Haswell
registers and on internal knowledge of how the Kernel is supposed to
work. Since we plan to test generic runtime PM on all supported
platforms, maintaining this test so it works on all those platforms
will be a pain. We already have some ideas on how to verify registers
that must stay at specific values from inside the Kernel, so let's
kill this test and wait until the proper Kernel code gets merged.

If you really want to reach the PC8+ states and consequently get PC8+
residency, you need to properly configure all the devices on your
machine to allow PC8+, not just graphics. The current code for PC8
checks for PC8+ residency everywhere, so if you have a machine that's
not properly configured you'll fail every test. OTOH, even if your
machine can't reach the PC8+ states, it will still try to enable and
disable PC8, so we can try to test the feature even if we're never
really reaching the PC8+ states. Also, if your machine does allow PC8+
residencies, but some other driver/program decides to keep the machine
busy while you're running the test suite, you'll also get failures
which you shouldn't be getting.
Based on the arguments above, I'm changing most of the subtests to
only check for the PC8 status reported by sysfs (enabled/disabled),
not check real PC8+ residency. I also added two tests that should
check for PC8+ residency, so we will stil be able to diagnose badly
configured machines.
As a bonus, we won't sleep for full 5 seconds every time we expect PC8
to be disabled: we'll just read i915_pc8_status, which quickly gives
the result we're expecting. Considering how many modeset stress
subtests we have in the program, we'll save a *lot* of time with this
change.

We try to detect if we have runtime PM or if we just have PC8. In case
there's runtime PM, the functions that wait will wait for the runtime
PM status reported by the sysfs file instead of waiting for PC8
residencies to move.
