eDP sink crc reads use vblank interrupts that cause PSR exit and
therefore makes them unsuitable for PSR testing. Besides that, reading
sink CRC via the AUX channel for testing when the HW also is most likely
is going to be using AUX channel is a recipe for inconsistent test
results. Thirdly, CRC's have been seen to be noisy/inconsistent across
sinks. We tradeoff the ability to validate what the sink is displaying
for correctness.
We also make use of source PSR status register to check whether HW tracking
triggered PSR exit upon an exit event.

Time intervals as produced by timersub() are normalized to have
the tv_usec in the range 0-999999. That leads to very confusing
looking debug output for negative interval. Eg. an interval
of -0.1 seconds would be represented as tv_sec=-1, tv_usec=900000.
Let's just convert the thing to a float seconds value and print
that so that we'll get less confusing debug output.

Apply a different sort of stress by timing how long it takes to sync a
second nop batch in the pipeline. We first start a spinner on the
engine, then when we know the GPU is active, we submit the second nop;
start timing as we then release the spinner and wait for the nop to
complete.
As with every other gem_sync test, it serves two roles. The first is
that it checks that we do not miss a wakeup under common stressful
conditions (the more conditions we check, the happier we will be that
they do not occur in practice). And the second role it fulfils, is that
it provides a very crude estimate for how long it takes for a nop to
execute from a running start (we already have a complimentary estimate
for an idle start).

When using the pollable spinner, we often want to use it as a means of
ensuring the task is running on the GPU before switching to something
else. In which case we don't want to add extra delay inside the spinner,

than the target latency.

If we allow 5s (+20% systematic error) to construct the fences, we may

We spread the same set of handles across different processes, with the

Distributions want explicit control over optional parts so they can
state runtime dependencies before building. Let's restore the
functionality autotools used to provide.
Where possible, the selection is done by choosing whether to build a
particular item and the option name is build_$item. Example:
build_overlay. Where not possible, the option name is
with_$item. Example: with_valgrind.
Array options require a bump of required meson version to 0.44. Debian
stable has meson 0.37 which is already too old, stable-backports has
0.45, CI uses 0.45. Mesa's meson requirement is 0.44.1, for a
perspective.
Note, the old hack for not building docs when cross-compiling is
gone, as doc building can be explicitly controlled now.

sw_sync/sync_multi_consumer_producer was communicating between threads
using the sw_sync ioctl and manipulating a shared volatile counter.
However, the ioctl itself does not imply a memory barrier, and so
different CPUs may see different states of the counter (the volatile
making GCC perform the operation in stages making the race even more
likely). Instead of using volatile, use locked operations to make the
counter manipulation thread-safe.
