|Feature open issues and risks=Chris Jones is writing the Direct3D 10/D2D texture sharing code, and will write the D3D9 composition of Basic (Cairo) cross-process layers.
== Summary ==
When Firefox is running with content processes, we need the ability to composite the layers the content process creates ("shadow" layers), using hardware acceleration, in the chrome process. This means we have to be able to composite Basic shadow layers (those drawn using Cairo) using Direct3D 9/OpenGL, but it also means we have to share texture data for compositing Direct3D 10/Direct2D-drawn shadow layers using Direct3D 10.

Open issues/risks

Chris Jones is writing the Direct3D 10/D2D texture sharing code, and will write the D3D9 composition of Basic (Cairo) cross-process layers.

It has not yet been decided who will do this work for OpenGL on OS X and Linux. This may be a simple task, because we already support compositing basic shadow layers using OpenGL.

Stage 1: Definition

1. Feature overview

`

2. Users & use cases

  • Draw into textures using Direct2D/D3D10, and share those to the chrome process for D3D10 composition. (Win7/Vista)
  • Draw into textures using Basic layers (Cairo) and share those to the chrome process for D3D9 and OpenGL composition. (WinXP/OS X/Linux)

3. Dependencies

`

4. Requirements

  • Support sharing D3D10 textures on Windows Vista and 7. Draw into these textures using the regular path of the Direct2D backend to Cairo. Composite these Direct3D 10 shadow layers using Direct3D 10 in the chrome process.
  • Support compositing basic shadow layers using Direct3D 9 on Windows XP, Windows 7, and Windows Vista.
  • Support compositing basic shadow layers using OpenGL on OS X.
  • Optional: Support compositing basic shadow layers using OpenGL on Linux.
  • No major performance regressions on any supported platform.

Non-goals

  • Cross-process WebGL.
  • Anything related to the Azure API.

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

Next Steps

  • Verify OpenGL composition of basic shadow layers on OS X.
  • Verify OpenGL composition of basic shadow layers on Linux.

Related Bugs & Dependencies

  • bug 641681 Tracking bug for platform dependencies for multi-process Gecko
  • bug 648484 Cross-process rendering with D2D and D3D10
  • bug 648480 Cross-process rendering of Basic shadow layers with D3D9
  • bug 654580 Cross-process rendering of Basic shadow layers with OpenGL on OS X
