media: iris: implement power scaling for vpu2 and vpu3

2025-02-07T10:51:55Z

Implement power scaling including a specific vpu2 and vpu3 calculation for clock and bus bandwidth, which depends on the hardware configuration, codec format, resolution and frame rate.

media: iris: add support for dynamic resolution change

2025-02-07T10:51:47Z

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.

media: iris: implement vb2 ops for buf_queue and firmware response

2025-02-07T10:51:45Z

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

media: iris: implement vb2 streaming ops

2025-02-07T10:51:33Z

During the stream on operation, send HFI_CMD_START on the capture and output planes to start processing on the respective planes. During the stream off operation, send HFI_CMD_STOP to the firmware, which is a synchronous command. After the response is received by the firmware, the session is closed on the firmware. Introduce different states for the 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 |<-----------+ ----------.

media: iris: implement iris v4l2_ctrl_ops

2025-02-07T10:51:30Z

Initialize the control handler by reading the platform specific firmware capabilities. Capabilities are features, which are supported by a specific platform (SOC). Each capability is defined with a min, max, range and default value and a corresponding HFI. Implement s_ctrl and g_volatile_ctrl ctrl ops.

Implement open, close and poll ops. Open: Configure the vb2 queue and v4l2 file handler. Allocate a video instance and add the instance to core instance list. Close: Free the instance and remove it from core instance list. Poll: Wait for an event on vb2 src and vb2 dst queues.
