| * bufferstreams: Present times are no longer Instants.James Shargo2024-02-162-18/+13
| | | | | | | | | | | | | | | | | | 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
| * bufferstreams: Make BufferOwner Send+SyncJim Shargo2024-02-161-1/+1
| | | | | | | | | | | | | | | | | | | | 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
| * bufferstreams: Add AIDL interfaces/parcelables for stream typesJim Shargo2024-02-167-0/+241
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add logging funtionatily to the example app.Carlos Martinez Romero2023-12-087-80/+185
| | | | | | | | | 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
* Updated the BufferStreamsDemoApp UI to jetpack compose.Carlos Martinez Romero2023-10-2616-65/+376
| | | | | | | | | | | | 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.

* libbufferstreams: Add Buffer, BufferPool and BufferOwner.Carlos Martinez Romero2023-10-165-6/+279
| | | | | | | | | | | | | | | | | 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.

| * bufferstreams: Add basic implementations of core BS traitsJames Shargo2023-09-229-42/+574
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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
