[Mesa-dev] [PATCH mesa 2/9] anv: Add KHR_display extension to anv [v5]

Tue Jun 12 05:39:51 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.
v2: Make sure primary fd is usable
When KHR_display is selected, we try to open the primary node
instead of the render node in case the user wants to use
KHR_display for presentation. However, if we're actually going
to end up using RandR leases, then we don't care if the
resulting fd can't be used for display, but the kernel also
prevents us from using it for drawing when someone else has
master.
v3:
Simplify addition of VK_USE_PLATFORM_DISPLAY_KHR to vulkan_wsi_args
Suggested-by: Eric Engestrom <eric.engestrom at imgtec.com>
v4:
Adapt primary node usage to new wsi_device_init API
v5:
Adopt Jason Ekstrand's coding conventions
Declare variables at first use, eliminate extra whitespace between
types and names. Wrap lines to 80 columns.
Remove spurious MM_PER_PIXEL define
