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 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.
v3: -Rebased on nouveau linux-5.6 @ 137c4ba7163ad9d5696b9fde78b1c0898a9c115b
-Noted corresponding Mesa patches are production-worthy now
-Better validate bo tile_mode when checking framebuffer size.
