[Mesa-dev] [PATCH 02/21] anv: Add KHR_display extension to anv
Keith Packard
keithp at keithp.com
Wed Feb 14 00:31:15 UTC 2018
This adds support for the KHR_display extension to the anv 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.
