Some potential callers want to inject a hang into a particular context,
some want to trigger an actual ban and others may or may not want to
capture the associated error state. Expand the hang injection interface
to suit all.
v2: Disable the new kernel API, but push to provide a missing piece of
infrastucture to unbreak compilation.

If we move the igt_require() into the hang injector, this makes simple
test cases even more convenient. More complex test cases can always do
their own precursory check before settting up the test.
However, this does embed the assumption that the first context we are
called from is safe (i.e no i915.enable_hangcheck/i915.reset
interferrence).
v2: A couple of environment variables to skip hang testing or to force
hang injection even if the GPU cannot be reset.

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.
Some stress tests create both the signal helper and a lot of competing
processes. In these tests, the parent is just waiting upon the children,
and the intention is not to keep waking up the waiting parent, but to
keep interrupting the children (as we hope to trigger races in our
kernel code). kill(-pid) sends the signal to all members of the process
group, not just the target pid.
We also switch from using SIGUSR1 to SIGCONT to paper over a race
condition when forking children that saw the default signal action being
run (and thus killing the child).

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

it gets the requested number of CRCs, whreas in non-blocking mode we

Speeds up testcases except for those where we want to exercise the
probing itself. The only exceptions left where we do a full probe are
- pm_rpm: We use it to make sure the kernel doesn't get things wrong
with power domains, so we really want to exercise the full probe
paths. And there the only place really is the specific validation
done with the data gathered by get_drm_info.
- kmstest_force_ functions: Newer kernels should be better at
re-probing state when the force sysfs fields change, but better safe
than sorry.
v2: I also consolidated the start_n_modes and start_connectors while
at it - move one of the fixup hunks to this patch that accidentally

placement of the GEM object can be specified, i.e. either

testing the gem_create ioctl call for stolen memory placement

v3: Removed get_aperture related functions, extended gem_pread

gem_set_caching() tries to be clever and detect when the ioctl isn't
supported (thereby skipping the test). However, it forget that we may be
acting on active objects and be subject to the usual EAGAIN/EINTR

get the automatic restart on the interrupted syscall.

If the caller is going to specify a custom size, it's likely that he
will also specify a custom stride. The automatic stride picked by
create_bo_for_fb() is too huge for tiled buffers, so if the caller
wants smaller buffers, then he'll need a smaller stride too, otherwise
the Kernel will reject the addfb IOCTL due to stride * height being
bigger than the size.
I want to make tests/kms_frontbuffer_tracking use
igt_create_fb_with_bo_size() so I can provide smaller buffers that
will fit into the CFB. I'm also planning to make all frontbuffers with
the same width/height/format have the same stride and size regardless
of tiling method so I can exercise specific code paths.

If we pass zero as the bo_size we won't get the minimum needed size,
we'll just get a size that works. The size is decided by
create_bo_for_fb(). The selected size is really not minimal for tiled
objects.
We'll implement support for minimum size later.

I want to have a little more control over the size of the buffers in
kms_frontbuffer_tracking, so I decided to start calling
igt_create_fb_with_bo_size() instead of igt_create_fb(). The problem
is that create_bo_for_fb() returns its own calculated size as size_ret
instead of the actual used size.
So we fix this by returning the actual size, the one used in
gem_create instead of the calculated size that's not used anywhere.
