[igt-dev] [PATCH i-g-t v5 0/4] Make sure v3d/vc4 support performance monitors

[Maíra Canal]

Currently, v3d and vc4 don't check if the driver supports the performance
monitor feature, which means that the tests are allowed to run even if the
driver doesn't support the tested feature. Therefore, this series adds checks
using the GET_PARAM ioctl from both drivers.

The main difference of this series is the introduction of the patches
"lib/igt_v3d: Rework igt_v3d_get_param()" and "lib/igt_vc4: Rework 
igt_vc4_get_param()", which will allow the tests to skip
instead of fail.

Best Regards,
