Merged as part of last week's Direct Rendering Manager (DRM) graphics/display driver fixes for Linux 6.12-rc2 are a few performance tuning updates for Intel Xe2 graphics to benefit the recently released Core Ultra 200 Series "Lunar Lake" laptops.

There are three patches as part of the recently merged fixes into Linux 6.12 for applying recommended performance tuning settings. The changes include extending performance tuning to the media GT engine, applying the tuned settings for future media GT versions too, and new performance tuning around L3 cache flushing.

These Xe2 performance tuning updates were sent out as part of last week's drm-xe-fixes. The L3 cache flushing performance tuning is mentioned to help out Lunar Lake (LNL) but the patch doesn't quantify any performance impact. These newly-merged patches don't appear to be any game changer but just further refining the Xe2 / Lunar Lake graphics support.

As noted last week, the Lunar Lake Xe2 graphics have been disappointing with my tests thus far. Intel is still looking into it and I haven't noticed any dramatically better results on 6.12-rc2. I do have some OpenCL compute benchmarks that I'll be publishing as well from Lunar Lake in the coming days.
