[igt-dev] [PATCH i-g-t 0/3] tests/gem_exec_alignment.c: Update subtests

[Dominik Grzegorzek]

Changes modify many subtest, and implement priority inversion test
case. Splited into three patches due to code sections shared between 
pi and many subtest. "PATCH i-g-t 1/3 tests/gem_exec_alignment.c: Timeout
alarm wrappers" has no sense without at least one of next patches.

[igt-dev] [PATCH i-g-t 2/3] tests/gem_exec_alignment.c: Update subtest many

[Dominik Grzegorzek]

Updated subtest many, that was unusable due to the long
time of execution. For that purpose global timeout was added.

[igt-dev] [PATCH i-g-t 3/3] tests/gem_exec_alignment.c: Add priority inversion test

[Dominik Grzegorzek]

Priority inversion test case was implemented, which can point out
that a low priority client causes a delay of a high priority client.

This still doesn't do quite what you would expect as it continues to
eat the signal anyway. In short it is no better than doing,

struct timespec tv = {}

for (alignment = 4096; alignment < gtt_size && igt_seconds_elapsed(&tv) < 5; alignment <<= 1)

>   tests/gem_exec_alignment.c: Add priority inversion test

Here, you don't want to try and fill the whole gtt and risk running for
several hundred seconds, but instead tune the fragmentation so that you
can reasonably expect it to take over 5s. i.e. use the slow
fragmentation loop from -many to consume 5s, and use the next alignment
up (on the already fragmented gtt) for the low-priority client.

Then don't use the SIGARLM for the high priority client, just measure
the elapsed time. Also fix up the igt_debug so that the L/H labels refer
to the right clients.
