Primes are useful as input sources since they should not fall into any
patterns that may be optimised by the drivers.
An example of use this in a test driver:
uint32_t seqno, inc, count;
seqno = inc = count = 0;
do {
inc = igt_next_prime_number(inc);
if (seqno + inc < seqno)
break;
seqno += inc;
/* igt_assert_eq(test_inc(inc), seqno); */
count++;
} while (1);
printf("count=%u, seqno=%u, last=%u\n", count, seqno, inc);
and prints "count=27878, seqno=4294845817, last=323381", or for simply
generating the set of the first N prime numbers, use
for_each_prime_number(prime, 100)
printf("%lu ", prime);
which prints
1 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 64 67 71 73 79 83 89

Note that 1 is included in the set of prime numbers for convenience
above. Mathematicians beware!
The set of primes is computed using the Sieve of Eratosthenes, which
basically just keeps a list of all multiples - any number not in list is
therefore prime. As a bitmask of all integers is kept, it can be quite
memory intensive for very large primes. A fallback to "trial division"
is available just in case, but for large primes that is much slower.

Similar to benchmarks/gem_latency, but looking more at the dispatch cost
rather than wakeup cost, and looking for inter-engine costs. Still
probably better as a perf test.

Add a heavier batch of (1M nops) in order to stress a context switch
onto a busy engine. (The immediate goal is try and fill the GuC
workqueue, but it seems like the lightweight test was enough anyway, as
well as gem_exec_nop.)

The ideal execution time cannot be faster than the fastest ring! If all
other rings were infinitely fast, the seed would be max/nengine. Given
each is finite, this puts a floor on the ideal execution time.

In an ideal world, we should be able to execute on every engine in
parallel and the single limiting factor would be how fast the GPU can
execute. Due to the serialisation in execbuf, we would lockstep with
execution to the slowest engine and so would execute the same number of
cycles on each. However in CI, we are limited by how fast the driver is,
particularly under invasive debugging. This makes asserting that the
average time == max/nengine impossible, and reveals that the assertion is
impossible to meet under general condition. It's an impractical
regression test. Therefore we relax the assertion to only detect should
something critically fail. Worst case behaviour is presumed that each
ring runs sequentially, and so running N rings in parallel should take no
longer than running N rings serially. (Pathologically it can be even
slower if no batching on the rings occur).

On skylake there's a add_all_affected_planes call that will make
atomic commit use the old cursor state. Add a test that first does
a page flip then cursor update to expose the issue. The test currently
fails on the vblank wait, but that's a common issue affecting all the
tests.

gem_busy.c:158:8: error: implicit declaration of function 'intel_gen'
is invalid in C99 [-Werror,-Wimplicit-function-declaration]
gen = intel_gen(intel_get_drm_devid(fd));
The root cause was due to the local lib directory not being specified
in benchmarks/Android.mk, resulting in intel_chipset.h from drm being
used instead.

Avoid having both the child and parent do the same "did the flip"
happen check with each looking for the same event on the same fd. The
problem being that the child may fall asleep and by the time it wakes up
to do its check, the parent has already eaten the event. So leave the
checking that the flip does occur to the parent.

We need to have the test list generated before running the check target.
Migrated igt_command_line.sh to tests/ from lib/tests/, which allows to
building the tests and execute the script.
This would allow cleaning followed by a make check.
Also assembler/ directory needs also to be adjusted in order for this
to work.
Kept the possibility to invoke tests/igt_command_line.sh to determine
which test is failing.

This is a simple test that only tries to set the current property
values back.
It exposes the issue that some connector properties only work when
set through the legacy path, because i915 doesn't handle atomic
connector properties yet. The other way around is true too:
The atomic CRTC_ID connector property cannot be set through legacy
means yet. This causes the connector tests to fail on i915.

It's possible to make use of disconnected connectors, for example
when overriding the mode or testing connector properties that don't
need it to be connected. Support this by zeroing the mode in that
case. We still return false, but this is ignored by commit.

Since we are experiencing too much noise in BAT from what just looks
like scheduling delays in inspecting the vblank, reduce the basic test
to the fundamentla: check that the cursor ioctl following the nonblocking
flip/modeset occurs within the same vblank. Hopefully, CI + debug builds
are fast enough to do get-vblank; flip; cursor; get-vblank within a
single vblank period.
