Accelerated layers on mobile via OpenGL ES	being actively worked	unknown	Stuart Parmenter

Summary

For greater performance, layers need to be composited using the GPU on mobile, leading to a better user experience and (probably) less battery usage.

We need to finish the OpenGL ES layers backend and get it working on multiple handsets.

Team

Who's working on this?

Lead Developer: Benoit Jacob
Product Manager: Chris Blizzard
QA: unknown
Security: unknown; necessary?

Benoit Jacob is getting OpenGL ES up and running on the Nexus S. Benoit and Joe Drew will be collaborating on completing the GLES layers implementation.

Release Requirements

Support at least two of the following handsets by default: Nexus One; Nexus S/Galaxy S; Droid Pro; Atrix.
- "Support by default" means that GLES-composited layers is turned on by default on a handset, that it has a performance benefit, and does not overly negatively affect stability.
- GLES composition of layers should be turned on via a whitelist rather than a blacklist, because of too many driver/stability issues.

Next Steps

Get GLES layer composition working on the Nexus S without generating GL errors with normal browsing.
Start running reftests, and solve the issues reftests find.
Iterate these steps for each handset.
Test these more generally on users' handsets, and solve issues that come up.
