2021-10-26android: Track and notify post processing of streamsUmang Jain
Notify that the post processing for a request has been completed, via a signal. The signal is emitted with a context pointer along with status of the buffer. The function CameraDevice::streamProcessingComplete() will finally set the status on the request descriptor and complete the descriptor if all the streams requiring post processing are completed. If buffer status obtained is in error state, notify the status to the framework and set the overall error status on the descriptor via setBufferStatus(). We need to track the number of streams requiring post-processing per Camera3RequestDescriptor (i.e. per capture request). Introduce a std::map to track the post-processing of streams. The nodes are dropped from the map when a particular stream post processing is completed (or on error paths). A std::map is selected for tracking post-processing requests, since we will move post-processing to be asynchronous in subsequent commits. A vector or queue will not be suitable as the sequential order of post-processing completion of various requests won't be guaranteed then. A streamsProcessMutex_ has been introduced here as well, which will be applicable to guard access to descriptor's pendingStreamsToProcess_ when post-processing is moved to be asynchronous in subsequent commits.

2021-10-26android: post_processor: Consolidate contextual informationUmang Jain
Save and provide the context for post-processor of a camera stream via Camera3RequestDescriptor::StreamBuffer. We extend the structure to include source and destination buffers for the post processor, along with CameraStream::Type::Internal buffer pointer (if any). In addition to that, a back pointer to Camera3RequestDescriptor is convenient to get access to overall descriptor (status, metadata settings etc.). Also, migrate CameraStream::process() and PostProcessor::process() signature to use Camera3RequestDescriptor::StreamBuffer only. This will be helpful when we move to async post-processing in subsequent commits.

2021-10-19android: camera_stream: Plumb process() with Camera3RequestDescriptorUmang Jain
Data (or broader context) required for post processing of a camera request is saved via Camera3RequestDescriptor. Instead of passing individual arguments to CameraStream::process(), pass the Camera3RequestDescriptor pointer to it. All the arguments necessary to run the post-processor can be accessed from the descriptor.

2021-08-10libcamera: Give MappedFrameBuffer its own implementationKieran Bingham
The MappedFrameBuffer is a convenience feature which sits on top of the FrameBuffer and facilitates mapping it to CPU accessible memory with mmap. This implementation is internal and currently sits in the same internal files as the internal FrameBuffer, thus exposing those internals to users of the MappedFramebuffer implementation. Move the MappedFrameBuffer and MappedBuffer implementation to its own implementation files, and fix the sources throughout to use that accordingly.

libcamera internal headers are not installed system-wide. Hence, any inclusion of internal headers should follow the #include directive form: #include "libcamera/internal/header.h" This was not the case for a few of the class in android HAL. Fix them.

2021-03-03android: post_processor: Use CameraBuffer APIJacopo Mondi
Use the newly introduced CameraBuffer class as the type for the destination buffer in the PostProcessor class hierarchy in place of the libcamera::MappedFrameBuffer one and use its API to retrieve the length and the location of the CameraBuffer plane allocated for JPEG post-processing. Remove all the assumption on the underlying memory storage and only go through the CameraBuffer API when dealing with memory buffers. To do so rework the Encoder interface to use a raw pointer and an explicit size to remove access to the Span<uint8_t> maps that serve as memory storage for the current implementation but might not be ideal for other memory backend. Now that the whole PostProcessor hierarchy has been converted to use the CameraBuffer API remove libcamera::MappedBuffer as base class of the CameraBuffer interface and only reply on its interface.

2021-02-02android: post_processor: Change the type destination in process()Hirokazu Honda
The type of the destination buffer in PostProcessor::process() is libcamera::Span. libcamera::Span is used for one dimension buffer (e.g. blob buffer). The destination can be multiple dimensions buffer (e.g. yuv frame). Therefore, this changes the type of the destination buffer to MappedFrameBuffer.

2020-10-21android: Modify PostProcessor interfaceHirokazu Honda
In PostProcessor::process(), the |source| argument doesn't have to be a pointer. This replaces its type, const pointer, with const reference as the latter is preferred to the former. libcamera::Span is cheap to construct/copy/move. We should deal with the type as pass-by-value parameter. Therefore this also drops the const reference in the |destination| argument.

2020-10-16android: post_processor: Introduce a PostProcessor interfaceUmang Jain
Introduce a PostProcessor interface for the streams that require any kind of processing (refer to CameraStream::Type) for their consumption by the HAL layer. The PostProcessor interface can be configured via configure() and the actual processing can be initiated using process(). The post-processing layer can be extended to have multiple post processors for various stream configurations. As of now, we only have one post processor (JPEG), hence the subsequent commit will port its function to this interface.
