IGT-Version: 1.25-gfd8248084 (x86_64) (Linux: 5.6.0-rc7-CI-CI_DRM_8194+ x86_64) Starting subtest: pipe-B Testing resolution with connector VGA-1 using pipe B with seed 1585245074 child 0 died with signal 11, Segmentation fault Subtest pipe-B: FAIL (0.330s) To fix this, we need move bandwidth calculation routines into part of igt_fixture instead of calculating it just before actual testing. The patch takes the minimum of those maximum number of planes for given output.
