gem_concurrent_blit tries to ensure that it doesn't try and run a test
that would grind the system to a halt, i.e. unexpectedly cause swap
thrashing. It currently calls intel_require_memory(), but outside of
the subtest (as the tests use fork, it cannot do requirement testing
within the test children) - but intel_require_memory() calls
igt_require() and triggers and abort. Wrapping that initial require
within an igt_fixture() stops the abort(), but also prevents any further
testing.
This patch restructures the requirement checking to ordinary conditions,
which though allowing the test to run, also prevents listing of subtests
on machines which cannot handle them.

Looks like I fumbled things when I made kms_chv_cursor_fail iterate

Several factors conspire against us when trying to execute
the tiled small-bo tests:
- pre-gen4 require power of two fences, with natural alignment
- the entire gtt may be mappable
- we put a guard page at the end of gtt
What all that means is that when we try to use a tiled object half
the size of the mappable area, we can only fit it in the first half
of the gtt. That leads to a SIGBUS when we try to fault in the
object when there's already something (eg. fbdev) occupying the
first half of gtt.
So in order to make the tests run on old machines, let's further
halve the object size when things look too tight.

The test tries to anger CHV pipe C cursor by walking the edges of the
screen while moving the cursor across the screen edge.
The actual hw issue only occurs on pipe C, and only on the left screen
edge. The testcase can walk all the edges though, and on all pipes, just
so I could make sure the failure doesn't occur there.

Add support for reading the CRC in non-blocking mode. Useful for tests
that want to start the CRC capture, then do a bunch of operations, then
collect however many CRCs that got generated. The current
igt_pipe_crc_new() + igt_pipe_crc_get_crcs() method would block until
it gets the requested number of CRCs, whreas in non-blocking mode we

So there's 3 competing proposals for what wait_ioctl should do wrt
-EIO:
- return -EIO when the gpu is wedged. Not terribly useful for
userspace since it might race with a hang and then there's no
guarantee that a subsequent execbuf won't end up in an -EIO.
Terminally wedge really can only be reliably signalled at execbuf
time, and userspace needs to cope with that (or decide not to
bother).
- EIO for any obj that suffered from a reset. This means big internal
reorginazation in the kernel since currently we track reset stats
per-ctx and not on the obj. That's also what arb robustness wants.
We could do this, but this feels like new ABI territory with the
usual userspace requirements and high hurdles.
- No -EIO at all. Consistent with set_domain_ioctl and simplest to
implement. Which is what this patch does.
We can always opt to change this later on if there's a real need.
To make the test really exercise this do a full wedged gpu hang, to
make sure -EIO doesn't leak out at all.

gem_flink_race and prime_self_import have subtests which read the
number of open gem objects from debugfs to determine if objects have

This reverts commit 4f5efc5c844f6fe69209982463f9220f8f3951ed.
There was a bit a misunderstanding on IRC between Chris&me. We want
basic tests as sanity test to be run in the BAT CI. It's just unfortunate
that right now we have fairly limited ability to absorb new ones, both
because of a pile of existing bugs in the kernel and because the CI
infrastructure is still being scaled out.
The idea was just to remove the BAT tests added yesterday, not all of
the ones we've had for a while longer.

In times past, I added "basic" variants of tests just to ensure that the
general principle of operation was sound before proceeding on to the
main test (which typically looked at thrashing, i.e. were long and
tedious and pointless if the test didn't even work in the normal
situation). Since "basic" now collides with BAT, rename my trivial tests
to "sanitycheck".

As the concurrency tests are a good source of stress for
i915_wait_request() (the tests are primarily designed to ensure that GPU
activity of one form or another is completed before access by third
parties), one of the common form of errors we can detect are the
"missing interrupts" (i.e. where the waits do not terminate because of a
race between the interrupt and the seqno write). Add an explicit check
for this error and flag it as a definite fail - which also helps narrow
it down to certain subtests when run as a batch.

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.

With commit (drm/i915: Delay first PSR activation.) in kernel
PSR might take a bit longer to really activate after the modeset.
The first PSR activation after modeset is taking 5 times the panel
power cycle delay time, which is 600ms for our machines here.
So timeout here needs to be a minimum of 3s. However let's use
5s as the safe value in case we find machines with higher power
cycle delay.
Since we do a lot of assert(psr_disabled), this commit is increasing
the time it takes to run the whole set of PSR tests by a few minutes,
which had been reduced by commit f4db3b18841
("kms_frontbuffer_tracking: reduce the PSR wait timeout to 2s").
