2023-10-18ipa: rpi: Prepare AWB for PiSP supportNaushir Patuck
Prepare the AWB algorithm to support the PiSP hardware. The key change is to factor in the LS correction in the AWB zone statistics. This is different from VC4 where the LS correction happens before statistics gathering.

The switchMode, prepare and process methods are updated to implement multi-channel AGC correctly: * switchMode now invokes switchMode on all the channels (whether active or not). * prepare must find what channel the current frame is, and run on behalf of that channel. * process updates the most recent DeviceStatus and statistics for the channel of the frame that has just arrived, but generates updated values working through the active channels in round-robin fashion. One minor detail in process is that we don't want to change the DeviceStatus metadata of the current frame, so we now pass this to the AgcChannel's process method, rather than letting it find the DeviceStatus in the metadata.

2023-09-16ipa: rpi: agc: Reorganise code for multi-channel AGCDavid Plowman
This commit does the basic reorganisation of the code in order to implement multi-channel AGC. The main changes are: * The previous Agc class (in agc.cpp) has become the AgcChannel class in (agc_channel.cpp). * A new Agc class is introduced which is a wrapper round a number of AgcChannels. * The basic plumbing from ipa_base.cpp to Agc is updated to include a channel number. All the existing controls are hardwired to talk directly to channel 0. There are a couple of limitations which we expect to apply to multi-channel AGC. We're not allowing different frame durations to be applied to the channels, nor are we allowing separate metering modes. To be fair, supporting these things is not impossible, but there are reasons why it may be tricky so they remain "TBD" for now. This patch only includes the basic reorganisation and plumbing. It does not yet update the important methods (switchMode, prepare and process) to implement multi-channel AGC properly. This will appear in a subsequent commit. For now, these functions are hard-coded just to use channel 0, thereby preserving the existing behaviour.

2023-09-04pipeline: rpi: Increase buffer import count to 32Naushir Patuck
Hardcode the maximum number of buffers imported to the V4L2 video device to 32. This only has a minor disadvantage of over-allocating cache slots and V4L2 buffer indexes, but does allow more headroom for using dma buffers allocated from outside of libcamera.

2023-08-29libcamera: stream: Document stride will be 0 for compressed formatsUmang Jain
For compressed formats, v4l2_pix_format.bytesperline value will be zero and is documented similarly in the kernel. Since we set the stride to v4l2_pix_format.bytesperline, document the case where it is expected to be zero (i.e. if the format is compressed).

The imx290 produces a single unusable frame on startup and mode switch. This is signalled to the IPA in the mode switch case, but not the startup case. Fix this.

Don't make an unnecessary call to toV4L2DeviceFormat() from validate() to get a V4L2DeviceFormat. Instead, the conversion can happen directly from the RAW stream PixelFormat.

The FocusFom metadata was no longer being reported back because the "focus.status" metadata was never being created. Additionally, the scaling of the focus FoMs was over-zealous, rounding just about everything down to zero.
