The way video buffer handling is programmed for i.MX27 leads to buffers being written when they are not ready.
It can be easily checked enabling DEBUG features of the driver. This series migrate the driver to videobuf2 and provide an additional discard queue to make sure all the events are handled in the right order. I've only tested the series with an i.MX27 device and so I've tried not to touch code scpecific for mx25. However, any mx25 tester would be more than welcome. [PATCH 1/4] media i.MX27 camera: migrate driver to videobuf2 [PATCH 2/4] media i.MX27 camera: add start_stream and stop_stream callbacks. [PATCH 3/4] media i.MX27 camera: improve discard buffer handling. [PATCH 4/4] media i.MX27 camera: handle overflows properly. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
