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.

Different than kms_mmap_write_crc that captures the coherency issues within the
scanout mapped buffer, this one is meant for test dma-buf mmap on !llc
platforms mostly and provoke coherency bugs so we know where we need the sync
ioctls.

This program can be used to detect when CPU writes in the dma-buf mapped object
don't land in scanout due cache incoherency.
Although this seems a problem inherently of non-LCC machines ("Atom"), this
particular test catches a cache dirt on scanout on LLC machines as well. It's
inspired in Ville's kms_pwrite_crc.c and can be used also to test the
correctness of the driver's begin_cpu_access and end_cpu_access (which requires
i915 implementation.
To see the need for flush, one has to run using '-n' option to not call the
sync ioctls which, via a rather simple CPU hog the system will trashes the
caches, while the test will catch the coherency issue. If you now suppress
'-n', then things should just work like expected.
I tested this with !llc and llc platforms, BTY and IVY respectively.
v2: use prime_handle_to_fd_for_mmap instead.
v3: merge end_cpu_access() patch with this and provide options to disable sync.
v4: use library's prime_sync_{start,end} instead.
v7: use CPU hog instead and use testing rounds to catch the sync problems.

These tests exercise the userptr ioctl to create shared buffers
between CPU and GPU. They contain error and normal usage scenarios.
They also contain a couple of stress tests which copy buffers between
CPU and GPU. These tests rely on the softpin patch in order to pin buffers
to a certain VA.
Caveat: These tests were designed to run on 64-bit system. Future work
includes adding logic to ensure these tests can run on 32-bit systems with
PPGTT support. Some tests are currently disabled for 32-bit systems for that
reason.
v2: Added cc and signed-off-by fields
v3: Fixed review comments, added helper functions. Removed userptr error
scenarios covered by existing userptr tests. Modified stress test to have
100K buffers, it now runs for ~30 mins, checks every element has been written
to correctly, and pins buffers at different VMAs.
v4: Changed name to gem_softpin
v5: More fixes. Removed the file based tests, will move them to userptr tests.
Added a function that validates appropriate PPGTT support before running tests.
Optimized stack space and memory footprint in stress test. Removed the eviction
test, will add it back after verifying proper functionality.
v6: Split basic test into userptr and bo
Fixed some coding style issues.
v7: Enhanced invalid vma pinning test to verify 32-bit PPGTT functionality.
Enabled the test for 32-bit PPGTT systems, and verify pinning fails above
32-bit addresses. Enhanced the high adress pinning test to ensure pinning
fails when EXEC_OBJECT_PINNED flag is not used. Some more cosmetic fixes to
close buffer handles. Changed userptr function to used synchronized operations.
v8: Minor change to high address pinning test as per comment.
v9: Skip the tests if softpin support is not present.
v10: Removed trailing white spaces.
v11: Keep alphabetical order in Makefile and gitignore; update error code
returned while trying to pin above the max vm size (EINVAL); test attempt
to pin above 4GB without the support 48b flag.

This test should test the interactions between fbcon and the
frontbuffer tracking infrastructure.
Right now the PSR test fails, but as soon as we merge the following
kernel patches, the test wills tart passing:
- drm/i915: PSR: Flush means invalidate + flush
- drm/i915: fbdev restore mode needs to invalidate frontbuffer
- drm/i915: fbdev_set_par reliably invalidating frontbuffer
I didn't want to make this a subtest of kms_frontbuffer_tracking just
because when I wrote it, I really didn't have in mind the fact that
someone might just close the DRM fd in the middle of a subtest.
After this commit we'll have a little bit of duplicated code among
tests. I'll clean this up later.

This is a new test that should exercise the frontbuffer tracking
feature of the Kernel in a number of different ways. We use different
drawing methods, we use the primary, cursor and sprite planes, we can
test both on single and dual pipes, also on buffers not associated
with any CRTCs, etc.
We currently have assertions for both FBC and PSR, and we also have a
"nop" test mode that should disable both FBC and PSR, and can be
used for debugging.
This test is also capable of testing both FBC and PSR even if they are
disabled by default on the Kernel: the test knows how to change the
i915.ko parameters and then set them back after testing.
I am getting a significant number of failures when I run this test,
which means we have some work to do on the Kernel.
I also still have a small list of additional subtests that I plan to
add to this test, and those tests are documented on the main function.
