mesa: querying dma_buf_modifiers for specific formats
|
|
|
|
mesa wl_drm protocol is the backend for wayland server side which requires
|
|
the dmabuf modifiers for some DRM formats on specific devices like RPI.
|
|
Currently there is no support of giving any dmabuf modifiers on wl_drm protocol.
|
|
This dma_buf modifiers allows EGL implementations to add extra attributes
|
|
to drm_fourcc format.
|
|
