drm/fourcc: Add packed 10bit YUV 4:2:0 format

2021-12-16T10:23:22+00:00

Adds a format that is 3 10bit YUV 4:2:0 samples packed into a 32bit word (with 2 spare bits). Supported on Broadcom BCM2711 chips. Signed-off-by: Dave Stevenson Signed-off-by: Maxime Ripard Acked-by: Thomas Zimmermann Link: https://lore.kernel.org/r/20211215091739.135042-2-maxime@cerno.tech

drm: Add R10 and R12 FourCC

2021-10-28T07:20:45+00:00

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 16 bpc fixed point framebuffer formats.

2021-05-27T19:00:47+00:00

These are 16 bits per color channel unsigned normalized formats. They are supported by at least AMD display hw, and suitable for direct scanout of Vulkan swapchain images in the format VK_FORMAT_R16G16B16A16_UNORM. Reviewed-by: Ville Syrjälä Signed-off-by: Mario Kleiner Signed-off-by: Alex Deucher

drm: Remove drm_get_format_name()

2021-05-27T06:34:50+00:00

The %p4cc printk format modifier was recently added to print fourcc codes, replacing drm_get_format_name(). The function is no longer needed, so remove it.

drm: drm_fourcc: add NV15, Q410, Q401 YUV formats

2020-06-19T12:33:40+00:00

DRM_FORMAT_NV15 is a 2 plane format suitable for linear and 16x16 block-linear memory layouts (DRM_FORMAT_MOD_SAMSUNG_16_16_TILE). The format is similar to P010 with 4:2:0 sub-sampling but 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 '15' suffix refers to the optimum effective bits per pixel which is achieved when the total number of luminance samples is a multiple of 8. Q410 and Q401 are both 3 plane non-subsampled formats with 16 bits per component, but only 10 bits are used and 6 are padded. 'Q' is chosen as the first letter to denote 3 plane YUV444, (and is the next letter along from P which is usually 2 plane).

drm/fourcc: Fill out all block sizes for P210

2019-11-28T10:19:32+00:00

0 means 1 as the default, but it's mighty confusing if the block size for the first plane is spelled out explicitly, but not for the 2nd plane. No cc: stable because this is just confusion, but 0 functional issue.
