Intel Pushes Out New GEM, KMS Patches
Developers at Intel's Open-Source Technology Center have been busy with a number of projects, and Jesse Barnes in particular has been active with a few kernel mode-setting and Graphics Execution Manager tasks.
Among other recent work, Jesse has put out new patches for KMS and GEM on the DRI development mailing list. One patch adds support for mapping of GEM objects if the underlying graphics driver supports it. The second patch is revised kernel mode-setting for the DRM (Direct Rendering Manager) and Intel driver. Compared to earlier patches, the size has been reduced and there's a few fixes, but more work is still ahead.
While not directly related to Intel or KMS/GEM, there are a few improvements in Mesa going on as well. Tungsten's Brian Paul has added support for the centroid qualifier and invariant keyword in the GLSL 1.20 implementation of this open-source OpenGL stack. Some of the other commits also add in AND/OR/NOT/XOR instructions and GL Shading Language support for DP2/DP2A/NRM3/NRM4 instructions. This work can be found in the Mesa git repository for what will go on to form Mesa 7.3 (and Mesa 7.4 once stabilized).
