The purpose of this test is to exercise the userspace latency hogs
reported by Arjan van de Ven. He found some applications blocked the
device by stalling on the GPU inside the pagefault handler.
Binaries should only be added to the HANG target if they're completely
broken. If they just cause a recoverable gpu hang as part of the test
then they need to be somewhere else.

QA has asked me "How can we make sure LPSP is working?". Now, instead
of writing big paragraphs, I can just answer "make sure pm_lpsp
works".

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
v3: Drop pwrite tests, call gem_bo_busy() after rendering, drop
set_domain() calls after mmap access, wait for 2 vblanks

Makefile.sources is just a listing with all the sources, and the logic
to use these sources goes into either Makefile.am (automake) or
Android.mk (make).

In this way, all source files are listed in Makefile.sources and included
from Makefile.am, thus enabling the reuse from Android makefiles.
