Phoronix readers are always happy to share desired features and requests within the forums in an always-lively discussion, but among the features that immediately come to my mind for some of the major outstanding Mesa items include:
- OpenGL 4.x support. While Mesa 10.0 manages to reach compliance for OpenGL 3.2 and 3.3, there's still a lot of work left for OpenGL 4.0, 4.1, 4.2, 4.3, and 4.4 compliance. It will probably not be until some time in 2014 when GL 4.0 support is reached, at which point there could already be OpenGL 4.5 or OpenGL 5.0.
- Other drivers lag behind in their OpenGL compliance. The Intel driver has GL 3.2/3.3 support on Mesa 10.0, but the Radeon and Nouveau Gallium3D drivers don't have as many OpenGL extensions implemented yet. The Gallium3D Softpipe and LLVMpipe drivers are also early on in their GL3 support.
- There still isn't any user-friendly control panel for fully controlling the different tunables of the Mesa/Gallium3D drivers in a nice manner. DRIConf isn't too friendly for end-users, especially gamers/enthusiasts converting from the nice options offered by the Windows drivers.
- The AMD RadeonSI driver for supporting the HD 7000, HD 8000, and Rx 200 series graphics cards still leave a lot to be desired. The RadeonSI driver doesn't support as many OpenGL extensions and the performance leaves a lot to be desired when compared to the R600g driver that supports earlier Radeon HD series graphics cards.
- The Clover Gallium3D state tracker for OpenCL compute support still isn't ready for prime-time use and leaves a lot to be desired compared to the full OpenCL support by the proprietary drivers.
- Canonical hasn't made any recent efforts yet to mainline their Mir display back-end support.
- Intel hasn't yet committed their Broadwell graphics support. Broadwell is the 2014 successor to Haswell.
What else do you see as a current limitation of the open-source Mesa drivers and you like to see in the future? Let us know in the forums!
