[igt-dev] [PATCH i-g-t] tests/kms_nv12: Add nv12 specific tests.

Srinivas, Vidya vidya.srinivas at intel.com
Wed Apr 18 09:52:36 UTC 2018


Thank you so much for the test patch.

Two subtests PASS with this nv12-rgb-switch and valid-width
Under subtest nv12-rgb-scaled-switch it tries to use more than 2 scalers. That fails on APL
Kernel Message: intel_atomic_setup_scalers: Too many scaling requests 3 > 2

Regards
Vidya
