2022-04-08ipa: ipu3: Replace event-based ops with dedicated functionsUmang Jain
The IPAIPU3 interface currently uses event-type based structures in order to communicate with the pipeline-handler (and vice-versa). Replace the event based structures with dedicated functions associated to each operation. The translated naming scheme of actions to signals are: ActionSetSensorControls => setSensorControls ActionParamFilled => paramsBufferReady ActionMetadataReady => metadataReady The translated naming scheme of events to dedicated functions are: EventProcessControls => queueRequest() EventStatReady => processStatsBuffer() EventFillParams => fillParamsBuffer() The dedicated functions are called from pipeline-handler to the IPA using IPC. These functions run asynchronously and when completed, the IPA emits the respective signals as stated above in the translated naming scheme. The EventProcessControls is translated to queueRequest() to bring symmetry to the IPU3 interface with other IPA interfaces.

2021-10-26Documentation: IPU3 IPA Design guideKieran Bingham
The IPU3 IPA implements the basic 3A using the ImgU ISP. Provide an overview document to describe its operations, and provide a block diagram to help visualise how the components are put together to assist any new developers exploring the code.
