Accept the DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK() family of modifiers to handle broken userspace Xorg modesetting and Mesa drivers. Existing Mesa drivers are still aware of only these older format modifiers which do not differentiate between different variations of the block linear layout. When the format modifier support flag was flipped in the nouveau kernel driver, the X.org modesetting driver

This series modifies the NV5x+ nouveau display backends to advertise appropriate format modifiers on their display planes in atomic mode setting blobs. Corresponding modifications to Mesa/userspace are available here: https://gitlab.freedesktop.org/cubanismo/mesa/tree/nouveau_work But those need a bit of cleanup before they're ready to submit. I've tested this on Tesla, Kepler, Pascal,

This doesn't look related. -James On 7/17/20 2:30 PM, Kirill A.

This series modifies the NV5x+ nouveau display backends to advertise appropriate format modifiers on their display planes in atomic mode setting blobs. Corresponding modifications to Mesa/userspace are available on the Mesa-dev mailing list as the series: nouveau: Improved format modifier support I've tested this on Tesla, Kepler, Pascal, and Turing-class hardware using various formats

Beyond general review, I'm looking for feedback on a few things specifically here: -Is the level of backwards compatibility described here sufficient? Technically I can make the user space drivers support the old modifiers too, but that would mean the layout they specify would morph based on the GPU they're being used on, and sharing buffers between two different NV GPUs, which would
