|
|
* HwcComposer2D provides a way for gecko to render frames
|
|
* using hwcomposer.h in the AOSP HAL.
|
|
*
|
|
* hwcomposer.h defines an interface for display composition
|
|
* using dedicated hardware. This hardware is usually faster
|
|
* or more power efficient than the GPU. However, in exchange
|
|
* for better performance, generality has to be sacrificed:
|
|
* no 3d transforms, no intermediate surfaces, no special shader effects,
|
|
* and loss of other goodies depending on the platform.
|
|
*
|
|
* In general, when hwc is enabled gecko tries to compose
|
|
* its frames using HwcComposer2D first. Then if HwcComposer2D is
|
|
* unable to compose a frame then it falls back to compose it
|
|
* using the GPU with OpenGL.
