drm/fourcc: Add QCOM tiled modifiers

2022-04-21T21:57:13Z

These are mainly used internally in mesa, although I believe the display should be able to scan out the TILED3 format. Currently we define this modifier internally in mesa for use with modifier based allocation. But we can get rid of that hack if we define the modfiers properly.

drm/fourcc: Introduce format modifier for DG2 clear color

2022-04-12T09:39:45Z

DG2 clear color render compression uses Tile4 layout. Therefore, we need to define a new format modifier for uAPI to support clear color rendering. v2: Display version is fixed. [Imre] KDoc is enhanced for cc modifier. [Nanley & Lionel] v3: Split out the modifier addition to a separate patch. Clarify the modifier layout description.

drm/fourcc: Introduce format modifiers for DG2 render and media compression

2022-04-12T09:39:43Z

The render/media engines on DG2 unify render compression and media compression into a single format for the first time, using the Tile 4 layout for main surfaces. The compression algorithm is different from any previous platform and the display engine must still be configured to decompress either a render or media compressed surface; as such, we need new RC and MC framebuffer modifiers to represent buffers in this format. v2: Clarify modifier layout description.

drm/i915: Introduce new Tile 4 format

2022-02-24T15:12:26Z

This tiling layout uses 4KB tiles in a row-major layout. It has the same shape as Tile Y at two granularities: 4KB (128B x 32) and 64B (16B x 4). It only differs from Tile Y at the 256B granularity in between. At this granularity, Tile Y has a shape of 16B x 32 rows, but this tiling has a shape of 64B x 8 rows.

drm: Add R10 and R12 FourCC

2021-10-28T07:20:45Z

Add FourCCs for 10- and 12-bit red formats with padding to 16 bits. They correspond to the V4L2 10- and 12-bit greyscale (V4L2_PIX_FMT_Y10 and V4L2_PIX_FMT_Y12) formats, as well as the Bayer formats with the same bit depth (V4L2_PIX_FMT_SBGGR{10,12} and all other Bayer pattern permutations). These formats are not used by any kernel driver at this point, but need to be exposed to applications by libcamera, which uses DRM FourCCs for pixel formats.

drm/fourcc: Add macros to determine the modifier vendor

2021-08-16T10:17:56Z

When working with framebuffer modifiers, it can be useful to extract the vendor identifier or check a modifier against a given vendor identifier. Add one macro that extracts the vendor identifier and a helper to check a modifier against a given vendor identifier.

drm/fourcc: Add modifier definitions for Arm Fixed Rate Compression

2021-07-23T15:10:22Z

Arm Fixed Rate Compression (AFRC) is a proprietary fixed rate image compression protocol and format. It is designed to provide guaranteed bandwidth and memory footprint reductions in graphics and media use-cases. This patch aims to add modifier definitions for describing AFRC.
