A set of userptr test cases to support the new feature.
For the eviction and swapping stress testing I have extracted
some common behaviour from gem_evict_everything and made both
test cases use it to avoid duplicating the code.
Both unsynchronized and synchronized userptr objects are
tested but the latter set of tests will be skipped if kernel
is compiled without MMU_NOTIFIERS.
Also, with 32-bit userspace swapping tests are skipped if
the system has a lot more RAM than process address space.
Forking swapping tests are not skipped since they can still
trigger swapping by cumulative effect.
v2:
* Fixed dmabuf test.
* Added test for rejecting read-only.
* Fixed ioctl detection for latest kernel patch.
v3:
* Use ALIGN macro.
* Catchup with big lib/ reorganization.
* Fixed up some warnings.

clean up the state back to PIPE_ANY properly so that following tests

[vsyrjala: collect the crc before disalbing the cursor]
Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com>
Currently this test is quite useless, since it only checks for valid CRCs when
the correct output from a test is a completely black screen (invisible or visible
but black cursor, or cursor is offscreen) and disables the check when anything
visible is onscreen.
This patch changes the cursor to a colorful one and removes the test cases
that become redundant because of this change. The cursor is designed to be
asymmetrical such that future tests involving rotation, mirroring, etc. produce
different CRCs and failures can be detected.
This (temporarily) disables CRC testing until the next patch which will add
software rendering of the cursor and the CRC generation.

Note that the sleep(5); to fully idle the gpu is _really_ important.
Without it the bug is not exhibited.
The issue at hand is that after gem_quiescent_gpu we are at max
(expected, since the blocking waits peg to max), but then we never go
down to a lower freq again until we're fully idle. The tiny load is
sufficient to keep the gpu at max. I've played around with this a bit
and even ridiculously low loads (like one MI_STORE per 50ms) are
enough to keep the gpu at max freq.
Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
Apparently some rps chips are prone to stick to max once you're there.
And all the synchronous waits in gem_quiescent_gpu are _really_ good
at forcing the kernel to go full throttle.
And even a positively tiny load (one MI_STORE_IMM per 50 ms) is enough
to eternally keeep it there, which means the first idle measurement of
the freqs before we do the reset it completely busted.
Just add a wait before the tricky test and call it a day.
Option b) would have been to now have this tiny load, but I think a
good reminder how quirky rps is is always welcome. Just in case we
start sleeping too easy at night.

Shorter and more in line with our general igt_ prefix for everything
which isn't somehow intel or i915-gem or otherwise hw specific - these
helpers here are all fully generic framebuffer handling functions
based on kms + cairo.
Well, the actual buffer alloc is done with i915 gem, but meh ;-)
Two special cases:
- bpp_depth_to_drm_format and drm_format_to_bpp completely lacked
prefixes, so just add igt_.
- write_fb was a bit misleading given that we have gem_write for
uploading to buffers. Rename that to write_fb_to_png to make it
crystal clear what this thing does even without looking at docs.

Use the new-style function using drm fourcc codes instead everywhere.
To easily use thew fourcc based interface also expose
