2022-06-19cam: drm: Support /dev/dri cards other than 0Eric Curtin
Existing code is hardcoded to card0. Since recent fedora upgrades, we have noticed on more than one machine that card1 is present as the lowest numbered device, could theoretically be higher. This technique tries every file starting with card and continue only when we have successfully opened one. These devices with card1 as the lowest device were simply failing when they do not see a /dev/dri/card0 file present.

2022-06-10android: camera_device: Print the correct number of completed streamsJacopo Mondi
When a request completes, a debug message is generated to help identify the request and the number of streams it contains. The printed number of streams is however the number of output buffers requested by the camera framework, not the number of streams generated by libcamera. In facts, some output buffers are generated by post-processing, and not directly from the camera. As the debug message prints the libcamera identifier for the Request, it is more logical to print the number of streams generated by the camera instead of the total number of streams.

We always call CameraManager.read_event() and CameraManager.get_ready_requests(), so to simplify the use merge the read_event() into the get_ready_requests(). This has the side effect that get_ready_requests() will now block if there is no event ready. If we ever need to call get_ready_requests() in a polling manner we will need a new function which behaves differently. However, afaics the only sensible way to manage the event loop is to use select/poll on the eventfd and then call get_ready_requests() once, which is the use case what the current merged function supports.
