[igt-dev] [PATCH i-g-t 12/14] tools/intel_display_poller: Add VRR push support
Ville Syrjala
ville.syrjala at linux.intel.com
Thu Dec 17 16:27:01 UTC 2020
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Add a new command line knob to specify the scanline on which we
should send the VRR push. This allows many of the test modes
to probe the hardware behaviour in the presence of VRR pushes.
