[PATCH v4 0/3] drm/nouveau: Support NVIDIA format modifiers

[James Jones]

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 gitlab merge request 3724:

  https://gitlab.freedesktop.org/mesa/mesa/merge_requests/3724

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.

v4: Do not cache kind, tile_mode in nouveau_framebuffer

James Jones (3):
  drm/nouveau: Add format mod prop to base/ovly/nvdisp
  drm/nouveau: Check framebuffer size against bo
