Unused code and abstraction needs removing. +* Without a 3A library the capture behaviour is not very good. To take a good + picture, the exposure/gain needs to be tuned using v4l2-ctl on the sensor + subdev. To fix this, support for the atomisp needs to be added to libcamera. -16. The AtomISP driver includes some special IOCTLS (ATOMISP_IOC_XXXX_XXXX) - and controls that require some cleanup. Some of those code may have - been removed during the cleanups. They could be needed in order to - properly support 3A algorithms. + This MUST be done before moving the driver out of staging so that we can + still make changes to e.g. the mediactl topology if necessary for + libcamera integration. Since this would be a userspace API break, this + means that at least proof-of-concept libcamera integration needs to be + ready before moving the driver out of staging. - Such IOCTL interface needs more documentation. The better would - be to use something close to the interface used by the IPU3 IMGU driver. -17.
