Android Accelerated Graphics Enablement
Each platform we have contains a core to offload graphics. We need to extend the existing support, bring up support for chips that haven't had accelerated graphics and plan for the future.

Whiteboard
Meta:
Roadmap id: ANDROID2012-
Goal:
Create a plan to transition support for Android hardware graphics enablement to the graphics team.
Agenda:
Talk about existing work
Builds:
~linaro-
Possible Mali card
~linaro-
SGX binaries from Google
~linaro-
SGX binaries from Google
~linaro-
Adreno (AMD/ATI Z160 and Z180)
~linaro-
SGX binaries from Google
~linaro-
Mali 400
~linaro-
SGX binaries from Google
~linaro-
SGX binaries from Google (broken)
~linaro-
None
~linaro-
Mali 400-MP
Talk about binary blob integration
Standard binary interfaces
Create a plan for the graphics team to have a bigger role in this work
-------
Meeting Minutes:
Zach >> History of Graphics enablement on Linaro supported platforms. Streamlining binary blobs.
Jesse >> All boards enabled but iMX53. Drivers available in past but current support of iMX53 is broken.
FSL >> Drivers for ubuntu and android are same.
Zach >> Why we need EGL?
Jesse >> EGL is Platform independent.
EGL takes care of:
Renderer Context and Configuration
Targeted Surface
Zach >> Why we need different stacks
Jesse >> Different graphics stacks per ARCH
EGL is abstraction layer
Native stack is common
Platform specific EGLs
Jesse >> Learning from Mesa/DRI experience
Direct Rendering
History: no common solution. targeted for particular ARCHs
DRI: Lock down enough resources for applications to interact with GPU without much hassles.
Mesa: Public s/w implementation of OpenGL
In quick time included h/w support
Android: Things no different here
Zach >> Lets make life easier
Jesse >> LTs don't have access to OpenGL libraries.
Zach >> open sourcing MALi drivers?
Jesse >> Ideally Yes but No for obvious reasons.
Action Items:
Jesse >> Standardise Android HALs (gralloc?) across all the boards.
Zach >> Document history
Roadmap for Graphics enablement
What is broken and why?
