      drm: Generalized NV Block Linear DRM format mod · 82c8c4dd
      James Jones authored
      Builds upon the existing NVIDIA 16Bx2 block linear
      format modifiers by adding more "fields" to the
      existing parameterized
      DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK format modifier
      macro that allow fully defining a unique-across-
      all-NVIDIA-hardware bit layout using a minimal
      set of fields and values.  The new modifier macro
      DRM_FORMAT_MOD_NVIDIA_BLOCK_LINEAR_2D is
      effectively backwards compatible with the existing
      macro, introducing a superset of the previously
      definable format modifiers.
      
      Backwards compatibility has two quirks.  First,
      the zero value for the "kind" field, which is
      implied by the DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK
      macro, must be special cased in drivers and
      assumed to map to the pre-Turing generic kind of
      0xfe, since a kind of "zero" is reserved for
      linear buffer layouts on all GPUs.
      
      Second, it is assumed backwards compatibility
      is only needed when running on Tegra GPUs, and
      specifically Tegra GPUs prior to Xavier.  This
      is based on two assertions:
      
      -Tegra GPUs prior to Xavier used a slightly
       different raw bit layout than desktop GPUs,
       making it impossible to directly share block
       linear buffers between the two.
      
      -Support for the existing block linear modifiers
       was incomplete, making them useful only for
       exporting buffers created by nouveau and
       importing them to Tegra DRM as framebuffers for
       scan out.  There was no support for adding
       framebuffers using format modifiers in nouveau,
       nor importing dma-buf/PRIME GEM objects into
       nouveau userspace drivers with modifiers in Mesa.
      
      Hence it is assumed the prior modifiers were not
      intended for use on desktop GPUs, and as a
      corollary, were not intended to support sharing
      block linear buffers across two different NVIDIA
      GPUs.
      
      v2:
        - Added canonicalize helper function
      
      v3:
        - Added additional bit to compression field to
          support Tesla (NV5x,G8x,G9x,GT1xx,GT2xx) class
          chips.

      UAPI Changes:
      
      - drm/i915: Show per-engine default property values in sysfs
      
          By providing the default values configured into the kernel via sysfs, it
          is much more convenient for userspace to restore those sane defaults, or
          at least know what are considered good baseline. This is useful, for
          example, to cleanup after any failed userspace prior to commencing new
          jobs.
