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, and Turing-class hardware using various formats and all the exposed format modifiers, plus some negative testing with invalid ones. NOTE: this series depends on the "[PATCH v3] drm: Generalized NV Block Linear DRM format mod" patch submitted to dri-devel. v2: Used Tesla family instead of NV50 chipset compare to avoid treating oddly numbered NV4x-class chipsets as NV50+ GPUs. Other instances of compares with chipset number in the series were audited, deemed safe, and left as-is for consistency with existing code.
