[libcamera-devel] [PATCH v1 0/2] Raspberry Pi: Timeout error handling

[Naushir Patuck]

Hi,

This small series attempts to improve our timeout handling.  We have been getting
more and more reports of ov5647 seemingly hitting the Unicam timeout condition,
likely due to a sensor fault. There is no error handling as such, simply a log
message indicating a timeout occurred, then an application gets stalled.

This series improves the timeout handling by putting the pipeline handler in
an error state, and cancelling any outstanding/future requests. The application
can then make a decision on what to do (either close down or attempt a restart)
when these requests come back as cancelled when it was not expecting this.

Thanks,
Naush
