2023-10-18ipa: rpi: Prepare ALSC for PiSP supportNaushir Patuck
Prepare the ALSC algorithm to support the PiSP hardware. The key change is to avoid factoring out the WB correction in the AWB zone statistics. Add the ALSC correction to the global metadata so that AWB can use it to factor the gains back in for the AWB calculations.

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.

2023-09-15README.rst: Drop recommendation to install meson using pip3Laurent Pinchart
Usage of pip3 to install meson may result in a different meson version available for the local user and for root. This causes issues when running `meson install` (directly or through `ninja install`): Installing to a system location will request elevated privileges and use the system meson version to install files, which may fail to unpickle data pickled with the meson version for the local user. As all major distributions now provide a recent-enough version of meson, usage of pip3 is not longer needed in most cases, and shouldn't be recommended. Drop it. While at it, update the version of meson listed in the documentation to match the required version.

We now time-filter the exposure before sorting out how much digital gain is required. This is actually a little more natural and simplifies the code. It also prepares us for some future work where this arrangement will be helpful.

2023-09-04ipa: rpi: agc: Fetch AWB status in process method, not prepareDavid Plowman
prepare() doesn't use the AWB status, so fetching it in process() is probably better. This change is preparatory to other changes, where we may find ourselves calling process() without having called prepare() previously.

There is no need to distinguish between dma bufs allocated outside of libcamera and internally allocated buffers. As such, remove all the special case handling of such buffers.

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.

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).
