drm/fourcc: Add formats for packed YUV 4:4:4 AVUY and XVUY permutations

2022-07-18T08:00:32+00:00

Add FourCCs for two missing permutations of the packed YUV 4:4:4 color
components, namely AVUY and XVUY.

These formats are needed by the NXP i.MX8 ISI. While the ISI is
supported by a V4L2 device (corresponding formats have been submitted to
V4L2), it is handled in userspace by libcamera, which uses DRM FourCCs
for pixel formats.

drm/fourcc: Add DRM_FORMAT_D[1248]

2022-07-09T13:36:07+00:00

As Rn covers single-channel formats with a direct relationship between
channel value and brightness, and Cn can be any colors, there are
currently no fourcc codes to describe single-channel formats with an
inverse relationship between channel value and brightness.

Introduce fourcc codes for a single-channel frame buffer format with
two, four, sixteen, or 256 brightness ("darkness") levels, where there
is an inverse relationship between channel value and brightness.

As the number of bits per pixel may be less than eight, some of these
formats rely on proper block handling for the calculation of bits per
pixel and pitch.

The fill order (the order in which multiple pixels are packed in a byte)
is the same order as used for grayscale (2, 4, and 16 levels) images in
the PNG specification, Version 1.2.
This order is also the recommended and default order (FillOrder = 1) for
bilevel and grayscale (16 levels) images in the TIFF 6.0 Specification,
and is also used for monochrome images in the PBM file format,
monochrome Linux frame buffer logos, and BDF and PSF (Linux kernel) font
files.

drm/fourcc: Clarify the meaning of single-channel "red"

2022-07-09T13:08:45+00:00

Traditionally, the first channel has been called the "red" channel, but
the fourcc values for single-channel "red" formats can also be used for
other single-channel formats with a direct relationship between channel
value and brightness, like grayscale.

drm/fourcc: Add DRM_FORMAT_C[124]

2022-07-09T13:02:50+00:00

Introduce fourcc codes for color-indexed frame buffer formats with two,
four, and sixteen colors, and provide a mapping from bits per pixel and
depth to fourcc codes.

As the number of bits per pixel is less than eight, these rely on proper
block handling for the calculation of bits per pixel and pitch.

The fill order (the order in which multiple pixels are packed in a byte)
is the same order as used for indexed-color (2, 4, and 16 colors) images
in the PNG specification, Version 1.2.
This order is also the recommended and default order (FillOrder = 1) for
palette-color (16 colors) images in the TIFF 6.0 Specification, and is
also used for 16-color Linux frame buffer logos.

drm/fourcc: fix integer type usage in uapi header

2022-06-23T21:21:38+00:00

Kernel uapi headers are supposed to use __[us]{8,16,32,64} types defined
by  as opposed to 'uint32_t' and similar. See [1] for the
relevant discussion about this topic. In this particular case, the usage
of 'uint64_t' escaped headers_check as these macros are not being called
here. However, the following program triggers a compilation error:

  #include 

  int main()
  {
  	unsigned long x = AMD_FMT_MOD_CLEAR(RB);
  	return 0;
  }

gcc error:
  drm.c:5:27: error: ‘uint64_t’ undeclared (first use in this function)
      5 |         unsigned long x = AMD_FMT_MOD_CLEAR(RB);
        |                           ^~~~~~~~~~~~~~~~~

This patch changes AMD_FMT_MOD_{SET,CLEAR} macros to use the correct
integer types, which fixes the above issue.
