[Mesa-dev] [PATCH 03/21] radv: Add KHR_display extension to radv
Keith Packard
keithp at keithp.com
Wed Feb 14 00:31:16 UTC 2018
This adds support for the KHR_display extension to the radv Vulkan
driver. The driver now attempts to open the master DRM node when the
KHR_display extension is requested so that the common winsys code can
perform the necessary operations.
