Android Accelerated Graphics Enablement

Registered by Zach Pfeffer on 2012-02-03

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.

SGX binaries from Google

~linaro-android/panda-ics-gcc46-tilt-tracking-blob

SGX binaries from Google

~linaro-android/snowball-ics-gcc46-igloo-stable-blob
Mali 400

~linaro-android/panda-ics-gcc46-omapzoom-stable-blob
SGX binaries from Google

~linaro-android/panda-ics-gcc46-tilt-stable-blob
SGX binaries from Google (broken)

~linaro-android/panda-ics-gcc46-kwg-upstream-open
None

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?
