media: iris: Add handling for corrupt and drop frames

2025-08-20T16:36:19Z

[ Upstream commit b791dcfcba3a0c46fb3e2decab31d2340c5dc313 ] Firmware attach DATACORRUPT/DROP buffer flags for the frames which needs to be dropped, handle it by setting VB2_BUF_STATE_ERROR for these buffers before calling buf_done.

media: iris: rename module file

2025-02-21T09:33:00Z

Build-testing on x86 showed two modules with conflicting "iris.ko" names after the addition of the qualcomm driver: error: the following would cause module name conflict: arch/x86/platform/iris/iris.ko drivers/media/platform/qcom/iris/iris.ko Since this a new module, nothing should rely on the name yet, so rename this one to a more specific "qcom-iris.ko".

media: iris: add support for drain sequence

2025-02-07T10:51:51Z

handle the V4L2_DEC_CMD_STOP by initiating a drain sequence on the firmware. Process and decode all OUTPUT buffers, that are queued by the client, before the VIDIOC_DECODER_CMD() was issued and mark the last buffer with the V4L2_BUF_FLAG_LAST flag. The decoder is stopped, after processing the last buffer. Resume the decoder when one of these operations are issued by the client: - V4L2_DEC_CMD_START - pair of VIDIOC_STREAMOFF() and VIDIOC_STREAMON() on the CAPTURE queue - pair of VIDIOC_STREAMOFF() and VIDIOC_STREAMON() on the OUTPUT queue Add the handling to resume decoding when client issues V4L2_DEC_CMD_START to resume decoding after a source change is detected.

Handle the response sent by the firmware, when a source change is detected. Read the subscribed parameter to get the changed values. Raise the source change event to the client and update the instance sub-state. Mark the last buffer from before the source change with the V4L2_BUF_FLAG_LAST flag and return to the client.
