Instead of measuring the wakeup latency of a GEM client, we turn the

competing with GEM. In particular, a realtime process that expects

Upcoming tests will call it to recover from bad states caused by
hangcheck bugs.the function was renamed to igt_force_gpu_reset to have a
naming closer to other hang-related functions in the same file.
The value written to the debugfs has also been changed to -1; this makes
no differences with the current implementation but copes with upcoming
TDR changes (still under discussion) that should allow the resetting of

This patch adds test_correct_cpu_write, which maps the texture buffer through a
prime fd and then writes directly to it using the CPU. It stresses the driver
to guarantee cache synchronization among the different domains.
This test also adds test_forked_cpu_write, which creates the GEM bo in one
process and pass the prime handle of the it to another process, which in turn
uses the handle only to map and write. Roughly speaking this test simulates
Chrome OS architecture, where the Web content ("unpriviledged process") maps
and CPU-draws a buffer, which was previously allocated in the GPU process
("priviledged process").
This requires kernel modifications (Daniel Thompson's "drm: prime: Honour
O_RDWR during prime-handle-to-fd") and therefore prime_handle_to_fd_for_mmap is
added to fail in case these lack. Also, upcoming tests (e.g. next patch) are
going to use it as well, so make it public and available in the lib.
v2: adds prime_handle_to_fd_with_mmap for skipping test in older kernels and
test for invalid flags.

I recently had this discussion with Daniel where I didn't want to use
igt_drm_format_to_bpp() because it uses the format_desc array, and
igt_fb currently assumes that all the format_desc formats have a
matching valid Cairo format, so I wouldn't be able to easily add
formats such as ARGB2101010.
The function that has the assumption mentioned above is
igt_get_all_formats: its current users call igt_get_all_formats, and
then call cairo-dependent functions, such as igt_get_cairo_ctx on the
returned formats.
In order to document the current behavior and prevent any problems in
case we start adding new formats without matching Cairo versions to
format_desc, rename igt_get_all_formats to igt_get_all_cairo_formats
and make it explicitly check for CAIRO_FORMAT_INVALID.

The big motivation behind this patch is that the current power-of-two
granularity from igt_fb is way too big. There was more than one
occasion where I had to work around this problem on
kms_frontbuffer_tracking, and during my last workaround I was
requested to just make igt_fb use more minimal buffers.
I also need to export the size computation function so I won't need to
reimplement it inside kms_frontbuffer_tracking.
v2:
- Fix the Yf sizes (Ville).
- Don't change the Gen 2/3 behavior for both tiled and non-tiled.

- Edit the commit message, clarify that v1 was wrongly treating gen
2/3 non-tiled as tiled (Chris).
