[RFC,v3,0/9] Gen12 E2E compression

Message

Dhinakaran Pandiyan Sept. 23, 2019, 10:29 a.m. UTC

Patches in this series are at two levels of completion.
The render decompression patches 1, 2, 3 and 4 address feedback provided
for https://patchwork.freedesktop.org/series/66367/

Media decompression patches 5, 6, 7, 8 and 9 are a complete rewrite to
handle planar formats and have not been tested. I would like to get
feedback on the approach before finishing the implementation.

Dhinakaran Pandiyan (9):
  drm/framebuffer: Format modifier for Intel Gen-12 render compression
  drm/i915: Use intel_tile_height() instead of re-implementing
  drm/i915: Move CCS stride alignment W/A inside
    intel_fb_stride_alignment
  drm/i915/tgl: Gen-12 render decompression
  drm/i915: Extract framebufer CCS  offset checks into a function
  drm/framebuffer: Format modifier for Intel Gen-12 media compression
  drm/i915: Skip rotated offset adjustment for unsupported modifiers
  drm/fb: Extend format_info member arrays to handle four planes
  Gen-12 display can decompress surfaces compressed by the media engine.
