Is there any detail description about "surface flinger"?

[Akl]

Read from the SDK, the "surface flinger" seems like control all the
display dispatch.
Is there any document or detail description about its operation?

Surfaceflinger is the abstraction for the 2D graphics engine.

I'm not sure I would agree with the statement "control all the display
dispatch", because there is a WindowManager layer above it in Java
that controls position, size, and Z-ordering. There is also
pixelflinger, which handles the low-level operations like scaling,
rotation, blending, etc.

The source code is the ultimate documentation. It's available here:
