drm/fourcc: define Intel Xe2 related tile4 ccs modifiers

2024-08-21T20:29:42+00:00

Add Tile4 type ccs modifiers to indicate presence of compression on Xe2. Here is defined I915_FORMAT_MOD_4_TILED_LNL_CCS which is meant for integrated graphics with igpu related limitations Here is also defined I915_FORMAT_MOD_4_TILED_BMG_CCS which is meant for discrete graphics with dgpu related limitations Signed-off-by: Juha-Pekka Heikkila Reviewed-by: Lucas De Marchi Acked-by: Maarten Lankhorst Link: https://patchwork.freedesktop.org/patch/msgid/20240816115229.531671-3-juhapekka.heikkila@gmail.com Signed-off-by: Rodrigo Vivi

drm/amd: GFX12 changes for converting tiling flags to modifiers

2024-04-26T21:22:58+00:00

GFX12 swizzle mode and GCC formats changed and is much simpler. Use a seperate function for the same. Changes: * Swizzle mode is now 3 bits only * DCC enablement doesn't come from tiling_flags, it is always set in modifiers * DCC max compressed block size of 128B Signed-off-by: Aurabindo Pillai Acked-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/fourcc: Add NV20 and NV30 YUV formats

2023-10-24T19:34:35+00:00

DRM_FORMAT_NV20 and DRM_FORMAT_NV30 formats is the 2x1 and non-subsampled variant of NV15, a 10-bit 2-plane YUV format that has no padding between components. Instead, luminance and chrominance samples are grouped into 4s so that each group is packed into an integer number of bytes: YYYY = UVUV = 4 * 10 bits = 40 bits = 5 bytes The '20' and '30' suffix refers to the optimum effective bits per pixel which is achieved when the total number of luminance samples is a multiple of 4.

drm/fourcc: Document open source user waiver

2023-01-05T12:10:38+00:00

It's a bit a FAQ, and we really can't claim to be the authoritative source for allocating these numbers used in many standard extensions if we tell closed source or vendor stacks in general to go away. Iirc this was already clarified in some vulkan discussions, but I can't find that anywhere anymore. At least not in a public link.

drm/fourcc: add Vivante tile status modifiers

2022-10-06T17:04:20+00:00

The tile status modifiers can be combined with all of the usual color buffer modifiers. When they are present an additional plane is added to the surfaces to share the tile status buffer. The TS modifiers describe the interpretation of the tag bits in this buffer.
