2024-09-10v4l2: Support setting frame rate in the V4L2 Adaptation layerNejc Galof
The V4L2 adaptation layer can already support streaming with components such as OpenCV, however it is not accepting, or handling any requests to configure the frame rate. In V4L2 the frame rate is set by configuring the timeperframe component of the v4l2_streamparm structure through the VIDIOC_S_PARM ioctl. Extend the V4L2 compatibility layer to accept the VIDIOC_S_PARM ioctls and provide an interface for setting controls on the V4L2Camera class to set the requested rate when starting the camera.

When a user is taking control of exposure and gain, setting them manually, we set the AGC "stable region" to zero. This means that any user changes, however small, will be applied, and they won't be regarded as "too small to bother with".

2024-08-30pipeline: uvcvideo: Implement acquireDevice() + releaseDevice()Hans de Goede
The uvcvideo pipeline handler always keeps the uvcvideo /dev/video# node for a pipeline open after enumerating the camera. This is a problem for uvcvideo, as keeping the /dev/video# node open stops the underlying USB device and the USB bus controller from being able to enter runtime-suspend causing significant unnecessary power-usage. Implement acquireDevice() + releaseDevice(), openening /dev/video# on acquire and closing it on release to fix this. And make validate do a local video_->open() + close() around validate() when not open yet, to keep validate() working on unacquired cameras.

2024-08-30libcamera: camera: Use invokeMethod() for pipe_->acquire() and pipe_->release()Hans de Goede
The uvcvideo driver needs to open / close its /dev/video# node from pipe_->acquireDevices() / pipe_->releaseDevices(). V4L2VideoDevice::open() creates an EventNotifier and this notifier needs to be created from the CameraManager thread. Use invokeMethod() for pipe_->acquire() and pipe_->release() so that the EventNotifiers are created from the CameraManager thread context. Running pipe_->acquire() and pipe_->release() from the CameraManager thread context serializes all calls to them. Drop PipelineHandler::lock_ this now is no longer necessary and update the "\context" part of the documentation for acquire[Device]() and release[Device]() to match. Note the delayed opening of /dev/video# is a special case because the kernel uvcvideo driver powers on the USB device as soon as /dev/video# is opened. This behavior should *not* be copied by other pipeline handlers.

2024-08-30pipeline_handler: Add acquireDevice() function to mirror releaseDevice()Hans de Goede
libcamera always keeps all /dev/video# and /dev/v4l2_subdev# nodes for a pipeline open after enumerating the camera. This is a problem for the uvcvideo pipeline handler. Keeping /dev/video# open stops the UVC USB device from being able to enter runtime-suspend causing significant unnecessary power-usage. Add a stub acquireDevice() function to the PipelineHandler class which pipeline handlers can override. The uvcvideo pipeline handler will use this to delay opening /dev/video# until the device is acquired. This is a special case because the kernel uvcvideo driver powers on the USB device as soon as /dev/video# is opened. This behavior should *not* be copied by other pipeline handlers.

index.rst is the page that becomes index.html, but currently just has some blurb. Although this page will only be seen if viewing the docs as built from the libcamera tree it'd be better if it were more of an introductory page. Include the content of docs.rst to improve it. As we're no longer including the content from README.rst the labels that enabled that can be dropped. With this change whether viewing the documentation as built in the libcamera tree or on the Docs page of the website, the landing content will be the same. The CSS for the documentation's theme currently hides the toctree from the generated body in html, as it's already displayed on every page via the theme's CSS. This change reorders the page such that the CSS that hides the toctree no longer works - update the CSS to retain the current behaviour.
