1125913 - Use GraphicBuffer::lockAsync() on gonk LL

Status: RESOLVED FIXED

(Core :: Graphics: Layers, defect)

Description

[Sotaro Ikeda [:sotaro]]

Since gonk LL, GraphicBuffer::lockAsync() is supported. It is better to use it to minimize the GraphicBuffer lock wait. But it require GRALLOC_MODULE_API_VERSION_0_3. Otherwise, the lock is done synchronously.

By the way, nexus-5's gralloc hal version is 2. Therefore async lock capability is not used.
