2024-02-16bufferstreams: Present times are no longer Instants. James Shargo
We need to be able to read these over the wire and send them as timestamps to C++ code. Replace the instants with a more compatible i64 timestamp nanos timestamp. Test: atest Change-Id: Ia63685ac406855b4a9257c661839640ab74a555c
2024-02-16bufferstreams: Make BufferOwner Send+Sync Jim Shargo
This is important for IPCs to work, since buffers can come in over the wire, be processed by binder threads, and handed off to client-controlled worker threads. Bug: 296099728 Test: atest Change-Id: I9c32ac17e07456aa6a8e7211c67893a51fc9724c
2024-02-16bufferstreams: Add AIDL interfaces/parcelables for stream types Jim Shargo
These interfaces incorporate jreck@'s ideas for caching and BufferAttachements. This means that we only need to send the heavy-weight HardwareBuffers once, and then we can just send a lightweight reference to the buffer. This interface is not intended for public use yet and is going to be actively developed for the next few months.

2023-12-08Add logging funtionatily to the example app. Carlos Martinez Romero
Logs can now be sent over from CPP to Kotlin and displayed in the LogOutput Card. Bug: 296272152 Test: Built and run on device. Change-Id: I79641dd9fbd6d04db0615579591a2bef4b24c914
2023-10-26Updated the BufferStreamsDemoApp UI to jetpack compose. Carlos Martinez Romero
The project is no longer using Java and now the MainActivity uses Kotlin, calling JNI from Kotlin is fairly simiar. Currently there are 3 empty demo screens, the first demo screen will call a JNI function but there is no support for logs. Bug: 296272152 Test: Built and ran on device.

2023-10-16libbufferstreams: Add Buffer, BufferPool and BufferOwner. Carlos Martinez Romero
This change adds supoprt for a simple buffer pool. Buffer pools can be notified when a buffer is dropped, so the buffer can be provided by the pool again. We introduced the concept of a BufferOwner, which is generic and can be implemented by a client for their own custom buffer pools. Along the way we updated the Frame struct to use a Buffer instead of a AHardwareBuffer.

2023-10-16libbufferstreams: Add the BufferPoolPublisher. Carlos Martinez Romero
The BufferPoolPublisher submits buffers from a pool over to a subscriber. Pair: jshargo Bug: 296450854, 296101127 Test: atest libbufferstreams-internal_test Change-Id: Ic473677c9c71b0505c3fcd2b4fb7d0fdf3d7d01b
2023-10-10nativewindow: Misc. improvements for AHardwareBuffer Rust wrapper Jim Shargo
Changes include: - Rename AHardwareBuffer to HardwareBuffer - Expose AHardwareBuffer as a raw pointer type - Making HardwareBuffer Send - HardwareBuffer now derives Debug, PartialEq and Eq - Use NonNull instead of a *mut pointer - Adding an into_raw function to match from_raw - Adding a Clone impl that acquires a ref Bug: 296449936, 296100790 Test: atest libnativewindow_rs-internal_test Change-Id: Iaf916fabe49190f47abd1a9ed34afdb76fd20e40

2023-09-22Bufferstreams test app. Carlos Martinez Romero
Used to test out BufferQueues and BufferStreams. Test: Ran the app. Bug: 296272152 Change-Id: Ie1192658bf7db49b2ccc216433585fbd1cd1bff7
2023-09-22bufferstreams: Add basic implementations of core BS traits James Shargo
For BufferSubscriptions, this change provides a generic implenmentation that tracks requests and cancellations. For BufferPublishers and BufferSubscribers, we provide test implementations that let a user manually control the flow of events between the two objects. The traits themselves have also been updated to be more generic--instead of forcing Arc/Weak pointers for shared objects, we now use generic owned types for a BufferPublisher's BufferSubscriber and a BufferSubscriber's BufferSubscription. To make it possible to hold into a handle to a BufferSubscriber while a BufferPublisher owns it, we provide a generic implementation of BufferSubscriber for any Arc<BS: BufferSubscriber> that delegates to the underlying subscriber.

2023-09-18libbufferstreams: Add a StreamConfig type (and associated trait methods) James Shargo
This type will be used to create publishers and subscribers, and contains enough information to create AHardwareBuffers. Bug: 296100790, 296450062 Test: atest libbufferstreams-internal_test Change-Id: I12a2aa59e8931ab77c658371d16450f3618de8ce
