| 2 | |
| 3 | mesa wl_drm protocol is the backend for wayland server side which requires |
| 4 | the dmabuf modifiers for some DRM formats on specific devices like RPI. |
| 5 | Currently there is no support of giving any dmabuf modifiers on wl_drm protocol. |
| 6 | This dma_buf modifiers allows EGL implementations to add extra attributes |
| 7 | to drm_fourcc format. |
