[asac Jun 10] alpha 3 planning: shift focus for clutter/
[asac Jul 10]: updated TI on how to properly package GL* libs from SGX
[asac Jul 10]: tested the gallium es -> gl binding and made https:/
[asac Sep 10]: postponing powervr review items as of release-meeting sep 9.
Status:
clutter/gles/eglx packages done; need archive upload/sponsoring
Work items (maverick-alpha-2):
Package and make available in the archive a build of Mesa with EGL/OpenGL support: DONE
[asac] Validate the Mesa EGL/OpenGL package: DONE
Investigate the feasibility of having Clutter use runtime loadable plugins for various backends (OpenGL, OpenGL ES 2.0): POSTPONE
Package and make available in a ppa a build of Clutter with OpenGL ES 2.0 support: DONE
Work items (maverick-alpha-3):
[asac] reach out to TI and imagination on finding appropriate ways to make the imagination user space libraries easily available in the archive; decide if and how to make those available: DONE
Work items (ubuntu-
[asac] implement distribution strategy decided with TI and imagination for the SGX userspace libraries (as decided in work item for alpha-2): DONE
Schedule regular calls/meetings with DX Team and vendors to coordinate efforts to solve any issues related to the functionality/
Work Items:
Coordinate with Unity team to make Unity work with Clutter OpenGL ES 2.0: DONE
Package and make available in a ppa a build of Unity Stack on top of OpenGL ES 2.0: DONE
Validate Unity OpenGL ES 2.0 package stack: DONE
[lnxtorez] make powervr kernel modules available in the archive for omap3 and omap4: POSTPONE
[lnxtorez] review powervr kernel code and write up suggestions on how to improve their code: POSTPONE
[asac] initiate discussion with imagination and vendors on results of powervr kernel code review from above : POSTPONE
Package and make available in the archive a OpenGL ES->OpenGL wrapper: DONE
Validate the OpenGL ES->OpenGL wrapper package: DONE
Package and make available in the archive plugins for a Clutter OpenGL and OpenGL ES 2.0 backends: POSTPONED
Provide a mechanism for loading the correct Clutter backend plugin depending on the platform: POSTPONED
Coordinate DX Team and vendors efforts to produce a specification of minimum driver/hardware requirements: TODO
tseliot 06-05-2010: tentative list of requirements
* Kernel driver:
- Compatibility with kernel 2.6.32 (Lucid) or higher.
- KMS (Kernel Mode Setting)
- Compatibility with the userspace libdrm 2.4.18 (Lucid) or higher
- Support for RandR output hotplug events (so that the xserver receives an event when external screens are connected or disconnected)
- GEM (Graphics Execution Manager), TTM (Translation Table Maps) or an alternative kernel video memory manager
- Dynamic front buffer resizing as in -intel's UXA (so that we don't have to set the virtual resolution and restart X when dealing with external screens using high resolutions)
* DDX (X.Org) driver:
- Compatibility with xserver 1.7.x (Lucid) or higher (1.8.x or 1.9.x)
- Support for RandR 1.3 (especially transformations, scaling, etc.)
- Use of the E-EDID functions in X.org (this is useful for HDMI)
- DRI 2 (Direct Rendering Infrastructure) which allows GLX applications to do direct rendering to redirected windows. This makes OpenGL and XV (X video extension) work correctly with compositing managers.
* Multimedia:
- Support for either VA-API (Video Acceleration API) or VDPAU (Video Decode and Presentation API for Unix) to allow video programs to offload portions of the video decoding process and video post-processing to the GPU video-hardware.
* 3D driver:
- OpenGL 2.1 (or later) compliant driver, more specifically we would like to have the following extensions available:
+ GL_ARB_
+ GL_ARB_
+ GL_ARB_
+ GL_ARB_
+ GL_EXT_
+ GL_ARB_
- Support for GLSL
* performance tests
- 3D tests
+ phoronix-test-suite (openGL based tests)
- 2D tests
+ gtkperf (to test performance with GTK+)
+ cairo-perf-trace (to test performance of apps which use cairo e.g. firefox)
