[0/6] libcamera: kernel headers update

26603 mbox series

Hello,

This patch series updates the kernel headers from v6.18 to v7.0.

The series starts (patch 1/6) by moving the local copy of
mali-c55-config.h, imported before it was merged in the mainline kernel,
to its correct location. The next three patches (2/6 to 4/6) then update
the update-kernel-headers to create the destination directory and copy
additional headers. Patch 5/6 performs the update to v7.0.

The v7.0 headers do not bring any important change for libcamera by
themselves, but we now import the drm.h and drm_mode.h headers. This
allows including the local copy of drm_fourcc.h, which patch 6/6 uses to
replace the version from libdrm.

As usual, some local changes to kernel headers are kept. They include

- DRM formats and modifiers that have not been upstreamed (for MJPEG,
  Bayer data, and raw CSI-2, IPU3 and RPI5 packing)

- BCM2835 (Raspberry Pi 4 and older) ISP formats and controls

- Internal pads and generic metadata

The last two categories are work in progress upstream (with the BCM2835
ISP being under review on the linux-media mailing list). DRM formats and
modifiers should be addresses separately, and I envision this will
involve decoupling the CFA pattern from the pixel format.
