[v3,00/21] libcamera: rcar-gen4 + rpp-x1

28338 mbox series

This is the first prototype implementation of the rppx1 ipa module
based on the new kernel uapi. It is the spiritual continuation of

  * https://patchwork.libcamera.org/cover/26915/
  * https://patchwork.libcamera.org/cover/24304/

But it includes both the pipeline handler and ipa components,
rebased on the current master branch.

The corresponding kernel branch is here: https://git.ideasonboard.com/renesas-v4h-isp/linux/src/branch/pobrn/rppx1

This has been an R-Car V4H Sparrow-Hawk device with the imx708 (and imx219) sensor(s).

Some points:

  * the isp always runs, even when only a raw stream is getting captured;
    this has been like this in previous version, so I did not change it

  * lens shading correction seemingly cannot be turned off,
    but this is most likely unrelated to libcamera
