Ben Widawsky suggested to use vasprintf, which perfectly fits the bill.
Also fix the logic conversion bug in tests/gem_storedw_batches_loop that
crept in again :(

igt runs under the assumption that nothing else (besides maybe fbcon)
is using the gpu. So we should be able to use all fences.
Keep the conservative testcase around though in case someone has a
broken setup.

If we're really fast we've trying to stop the signal helper again
we somehow race somewhere and it'll never happen. So add a testcase for
this. Since I expect more to come for testsuite tests add a separate
make target for them. Run tests with
$ make check

- Clear the igt_helper_process struct to avoid hitting asserts.
- Fix up the logic for enumerating forked processes.

drm/i915: Don't forget to apply SNB PIPE_CONTROL GTT workaround.
If a buffer that was the target of a PIPE_CONTROL from userland was a
reused one that hadn't been evicted which had not previously had this
workaround applied, then the early return for a correct
presumed_offset in this function meant we would not bind it into the
GTT and the write would land somewhere else.
Fixes reproducible failures with GL_EXT_timer_query usage in apitrace,
and I also expect it to fix the intermittent OQ issues on snb that
danvet's been working on.

The warning that vmap isn't supported is useful, but it shouldn't get in
the way of developers (or distros) being able to use -Werror.

We need to be careful to remember that fb-width is not always the same
as hdisplay, since for panning we allocate a larger framebuffer. So fix
up the printfs to use hdisplay/vsisplay since that should be uniform
across the array.

kms_flips: Operate on an array of crtc

Much better at hitting the list corruption here on my machines
than what we have thus far.
Note that somehow I just can't reproduce the bug any more. No idea
why. But I guess it's time to simply push this pile out.
v2: Limit threads and rounds to something reasonable.
v3: Use igt_permute_array to avoid EINVAL due to duplicated bo.
v4:
- Add a variant of the forked tests with multiple drm fds.
- Tune the swapped forked tests a bit to complete in a reasonable
amount of time.
v5: Add some memory pressure from the cpu by using cpu mmaps (which
directly hit shmem, so bypass gem completely).

This turned out to be the reason one one of my tests was hitting
the list corruption bug - we need a good deal more memory pressure.
So I'll now add a new testcase for that.

Making sure that we correctly collect the exit codes from all children
is a bit a hassle. So add another magic igt codeblock for easy forking
and joining.
Note that children are (currently at least) not allowed to call igt_skip.
Add an assert to enforce this.
v2:
- Properly propagate the exit code.
- Fix the segfault.
- Add a child int and num_children paramter to the magic codeblock as
suggested by Chris Wilson.
- Don't dump noise into stdout when a child thread fails, the parent
will do that for us already.
v3: Now with some docs.
v4: Fixup igt_waitchildren to properly reset state so it can be used
again.

The goal is to flip the same framebuffer on a pair of CRTCs (clone mode)
and check that (a) the flip works in all combinations of workloads, and
(b) that we can hit the desired refresh rate under the simplest, most
ideal of conditions.

This should be no functional change as we operate on an array of
crtc[1]. Later we shall test clone mode across a number of crtc.
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
For machine with split BCS/RCS rings, we also need to test whether we
correctly wait upon outstanding render work before flipping and changing
modes. This should also serve to exercise the ring selection code for
flips.

I wanted to write a testcase for gtt mmap access restriction checking

Also I've stumbled over igt_fixture again. Somehow gcc loves to wreak
havoc with stack variables set up in igt_fixtures ... Duct-tape in the
