A lot of igt testcases need some dummy load 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 is dynamically tuned to consume a
specific amount of time.
This functionality is generalized to lib from existing features in
gem_wait and kms_flip. In the future, we could update test cases
that could benefit from auto-tuned dummy workloads to use this
new api.
