media: iris: Add V4L2 streaming support for encoder video device

2025-09-10T07:02:42Z

Add support for V4L2 streaming operations on the encoder video device. During stream-on, configure mandatory properties on the respective planes and notify the firmware to initiate an encode session.

media: iris: rename module file

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".

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 |<-----------+ ----------.
