There are 3 types of queues: Command queue - driver to write any command to firmware. Message queue - firmware to send any response to driver. Debug queue - firmware to write debug messages. Initialize and configire shared queues during probe. Different states for core: IRIS_CORE_DEINIT - default state. IRIS_CORE_INIT - core state with core initialized. FW loaded and HW brought out of reset, shared queues established between host driver and firmware. IRIS_CORE_ERROR - error state. ----------- | V ----------- | DEINIT | ----------- ^ / \ / \ / \ / \ v v ----------- ----------. | INIT |-->| ERROR | ----------- ----------.

During stream off, send HFI_CMD_STOP to firmware which is a synchronous command. After the response is received from firmware, the session is closed on firmware. Introduce different states for instance and state transitions. IRIS_INST_INIT - video instance is opened. IRIS_INST_INPUT_STREAMING - stream on is completed on output plane. IRIS_INST_OUTPUT_STREAMING - stream on is completed on capture plane. IRIS_INST_STREAMING - stream on is completed on both output and capture planes. IRIS_INST_DEINIT - video instance is closed. IRIS_INST_ERROR - error state. | v ------------- +---------| INIT |--------- + | ------------- | | ^ ^ | | / \ | | / \ | | v v | | ----------- ----------- | | | INPUT OUTPUT | | |---| STREAMING STREAMING |---| | ----------- ----------- | | ^ ^ | | \ / | | \ / | | v v | | ------------- | |--------| STREAMING |-----------| | ------------- | | | | | | | | v | | ----------- | +-------->| DEINIT |<----------+ | ----------- | | | | | | | | v | | ---------- | +-------->| ERROR |<-----------+ ----------.

Below are the different buffer attributes: BUF_ATTR_DEFERRED - buffer queued by client but not submitted to firmware. BUF_ATTR_PENDING_RELEASE - buffers requested to be released from firmware. BUF_ATTR_QUEUED - buffers submitted to firmware. BUF_ATTR_DEQUEUED - buffers received from firmware. BUF_ATTR_BUFFER_DONE - buffers sent back to vb2.

Process and decode all OUTPUT buffers queued by the client before the VIDIOC_DECODER_CMD() was issued and mark the last buffer with V4L2_BUF_FLAG_LAST flag. Decoder is stopped after processing the last buffer. Resume the decoder when one of below are issued by 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 source change is detected.
