[PATCH igt] igt/gem_mocs_settings: Force use of master device

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



To use SECURE batches requires root + master, and we need SECURE batches
to write to the privileged mocs registers, do be sure to use
drm_open_driver_master()
