[igt-dev] [PATCH i-g-t RFC v2 0/4] VC4 load tracker testing

[Paul Kocialkowski]

This series introduces helpers and a simple test (with three subtests)
for testing the VC4 load tracker. See the final commit message for
more details about the test.

This series is posted as RFC since the kernel piece are still under
review. It allows testing the series with IGT in the meantime (and was
used for testing the kernel side).

The two preliminary patches were already sent as part of another series
and are included so that CI can attempt to build the whole series.

Changes since RFC v1:
* Split sub-tests into underrun-detection and bandwidth-detection;
* Updated preliminary patches;
* Rebased to latest upstream master;
* Dropped autotools support.

Cheers,

Paul
