e70c789909 igt/gem_tiled_wc: Exercise wc mmaps with swizzling
This exercises both the wc mmappings and the extended get_tiling ioctl.
Userspace cannot handle bit17 swizzling through wc mmaps (because bit17
requires swizzling based on the actual physical address of the page -
which is unknown to userspace) and so we need an extended get_tiling
ioctl to report the actual as well as the logical swizzling on an
object. We then check that the contents of the object are tiled and
swizzled correctly when viewed through a wc mmap.

f12ed83058 tests/kms_pwrite_crc: Add pwrite vs display coherency test
Add a test to verify that pwriting to a future scanout buffer works
correctly. The specific problem occurs when the buffer is already
UC/WT before the pwrite, not the current scanout buffer, and not
currently in the CPU write domain. With the buggy kernel no clflush
will be performed after the pwrite, and hence we end up with cache
dirt on the display.

The problem only affects LLC platforms (non-LLC would clflush anyway
after pwrite), but we can let the test run on all platforms.

v2: Fix typos in commit message and add to .gitignore

075d9eafdb tests/kms_universal_plane: Universal plane testing (v6)
Add a simple test to exercise universal plane support.

v6:
 - Update to new universal plane interface (commit parameter rather than
   state-changing function).  It should now be a lot more explicit which
   steps are being taken with legacy API's vs universal API's now.
v5:
 - Check that we don't have more than one primary or cursor.  This will
   catch accidental calls to drm_plane_init() in the kernel where
   drm_universal_plane_init() was intended (these don't cause a compile
   warning due to type compatibility between enum and bool).
v4:
 - Test disabling the primary plane explicitly when it has previously
   been implicitly disabled due to clipping.
 - Skip test if igt_pipe_crc_new() fails
v3:
 - For testing while crtc is off, switch between several different
   primary plane fb's before reenabling the crtc.  This will help
   catch pin/unpin mistakes.
v2:
 - Test that pageflips error out gracefully when the primary plane
   is disabled before the ioctl, or between ioctl and pageflip
   execution.
 - Test that nothing blows up if we try to disable the primary plane
   immediately after a pageflip (presumably before the pageflip actually
   completes).
 - Test that we can setup primary + sprite planes with the CRTC off and
   then have them show up properly when we enable the CRTC
   (drmModeSetCrtc with fb = -1).
 - Test that we can modeset properly after having disabled the primary
   plane
 - Test that proper error codes are returned for invalid plane
   programming attempts.

78f79e4e95 tests/kms_fence_pin_leak: Exercise full ppgtt fence pin_count leak in the kernel
The kernel full ppgtt support has a bug where it can drop a pinned
fence to the floor, hence we leak the pin_count as the subsequent
fence unpin becomes a nop. We can trigger it easily by unbinding a
buffer from a ppgtt address space while the buffer is simultaneosly
being used for scanout.

Make the kernel leak the fence pin_count and trick it into picking
a new fence register for the next scanout buffer. Looping like
this for a while we leak the pin_count for all fence registers after
which the kernel can no longer find a new fence register when it needs
one. As a result we get back a SIGBUS from the GTT mmap access.

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.

ddf8cc107e test: Add test for checking if page flip changes tiling
Test that a page flip from a tiled buffer to a linear one works
correctly. First, it sets the crtc with the linear buffer andr
generate a reference crc for the pipe. Then, the crtc is set with
the tiled one and page flip to the linear one issued. A new crc is
generated and compared to the rerence one.

a388f3b98f lib: allow igt_skip_on_simulation outside of fixtures.
Thomas noticed that in simulation mode a lot of the tests fall over
instead of skipping properly. This is due to recently added
self-checks which ensure that any call to igt_skip happens either
within a fixture or subtest block (or it's a simple test without
subtests). This is to catch bugs since pretty much always not wrapping
up hardware setup and checks into these blocks is a bug.

Bug simulation skipping is a bit different, so allow that exception.
Otherwise we'd need to fix up piles of tests (and likely need to play
a game of whack-a-mole).

Also add a library testcase for all the different variants to make
sure it really works.
