|
* We use the BufferCache to reduce the overhead of exchanging GraphicBuffers with
|
|
* the server. If we were to simply parcel the GraphicBuffer we would pay two overheads
|
|
* 1. Cost of sending the FD
|
|
* 2. Cost of importing the GraphicBuffer with the mapper in the receiving process.
|
|
* To ease this cost we implement the following scheme of caching buffers to integers,
|
|
* or said-otherwise, naming them with integers. This is the scheme known as slots in
|
|
* the legacy BufferQueue system.
|
|
* 1. When sending Buffers to SurfaceFlinger we look up the Buffer in the cache.
|
|
* 2. If there is a cache-hit we remove the Buffer from the Transaction and instead
|
|
* send the cached integer.
|
|
* 3. If there is a cache miss, we cache the new buffer and send the integer
|
|
* along with the Buffer, SurfaceFlinger on it's side creates a new cache
|
|
* entry, and we use the integer for further communication.
|
|
* A few details about lifetime:
|
|
* 1. The cache evicts by LRU. The server side cache is keyed by BufferCache::getToken
|
|
* which is per process Unique. The server side cache is larger than the client side
|
|
* cache so that the server will never evict entries before the client.
|
|
* 2. When the client evicts an entry it notifies the server via an uncacheBuffer
|
|
* transaction.
|
|
* 3. The client only references the Buffers by ID, and uses buffer->addDeathCallback
|
|
* to auto-evict destroyed buffers.
