team/2021-March/118504.html (oem-5.10)
** Description changed:
- The Intel imaging processing unit version 6, found in Intel SoCs and
- used for capturing images and video from a camera sensor is enabled by
- integration of following kernel driver, firmware, userspace HAL
- libraries as well as a GStreamer source element:
+ [SRU Justification]
+
+ [Impact]
+
+ There are new platforms with MIPI camera based on Intel IPU6(Imaging
+ Processing Unit version 6) currently unsupported in Ubuntu.
+
+ [Fix]
+
+ Intel IPU6 can be enabled by integration of following kernel driver,
+ firmware, userspace HAL libraries as well as a GStreamer source element:
* https://github.com/intel/ipu6-drivers
* https://github.com/intel/ipu6-camera-bins
* https://github.com/intel/ipu6-camera-hal
* https://github.com/intel/icamerasrc
- With all components properly installed, the hardware should be ready for
+ This patchset took kernel patches from intel/ipu6-drivers.
+
+ [Test Case]
+
+ With kernel/firmware properly installed, the hardware should be ready for
further development:

+
+ There should be nearly 24 video4linux devices created under /dev.
+
+ [Where problems could occur]
+
+ MIPI camera through Intel IPU6 takes also firmware blobs loaded in
+ runtime from user space, addtional softwares are also required to
+ fully enable it for oridinary use. The exposed video devices are hidden
+ from general users and a relay daemon+v4l2loopback is used to enable
+ use from existing applications.
+
+ >From kernel's point of view, there is still a known issue that it takes
+ root priviledge to access these devices.
+
+ [Other Info]
+
+ So far Intel has no plan to commit this driver to upstream yet, so it's
+ only nominated for oem-5.10. It will only be nominated to generic
+ kernels when the plan/requirements have changed.
+
+ The original driver Kconfig would disable VIDEO_IPU3_CIO2, but that's
+ reverted to avoid unnecessary changes to existing users.
