[PATCH 1/7] vulkan: Add KHR_display extension to anv and radv using DRM
Mao, David

Hi Keith,
If I read the patch correctly, the plane has been interpreted as the same as connector, and the stackIndex is the index of connector of current device.
Is it by intentional?
If the hardware don't have underlay/overlay supported, is it better to always report plane 0 rather than pretend to have multiple plane?
Thanks.
Best Regards,
David

Subject: [PATCH 1/7] vulkan: Add KHR_display extension to anv and radv using DRM
This adds support for the KHR_display extension to the anv and radv
Vulkan drivers. The drivers now attempt to open the master DRM node
when the KHR_display extension is requested so that the common winsys
code can perform the necessary operations.
