A lot of igt testcases need some GPU workload to make sure a race
window is big enough. Unfortunately having a fixed amount of
workload leads to spurious test failures or overtly long runtimes
on some fast/slow platforms. This library contains functionality
to submit GPU workloads that should consume exactly a specific
amount of time.
v2: Add recursive batch feature from Chris and use in gem_wait and
kms_flip. I've retained the previous auto-tuned dummy load
functions. Let me know if we need to drop those.
Abdiel Janulgue (3):
lib: add igt_dummyload
igt/gem_wait: Use new igt_spin_batch
igt/kms_flip: Use new igt_spin_batch
