Accelerated layers on mobile via OpenGL ES
Stage Development
Status In progress
Release target Firefox 10
Health OK
Status note Working pretty well, still has some bugs. Still looking for better performance numbers. Anecdote - scrolling is better, still work to do though.

Open issues/risks

`

Stage 1: Definition

1. Feature overview

`

2. Users & use cases

  • Hardware accelerate the composition of layers generated in the content process in the chrome process using OpenGL ES.
  • Speed up the browsing experience for users.

3. Dependencies

`

4. 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.

Non-goals

  • Cross-process WebGL.

Stage 2: Design

5. Functional specification

`

6. User experience design

`

Stage 3: Planning

7. Implementation plan

`

8. Reviews

Security review

`

Privacy review

`

Localization review

`

Accessibility

`

Quality Assurance review

Operations review

Stage 4: Development

9. Implementation

Florian Hänel has been working on completing the layers implementation, mostly on Maemo. Benoit Jacob is getting OpenGL ES up and running on the Nexus S. Florian, Benoit, and Joe Drew will be collaborating on completing the GLES layers implementation.

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.

Stage 5: Release
