Author: Lucas Stach <[email protected]> Date: Mon Mar 26 16:39:28 2018 +0200 st/dri: allow both render and sampler compatible dma-buf formats Currently all the EGL APIs are missing a way to specify how an imported dma-buf is intended to be used. Demanding the format to be both usable for sampling and rendering artificially restricts the list of formats a driver is able to import. Looking at how the Intel driver implements those DRI2 image APIs it doesn't distinguish between render or sampler compatible formats. So this patch aligns behavior between Intel and Gallium based drivers.
