5/9/2023 0 Comments Intel graphics driver latestStolen memory probing fix and a missing register whitelisting for Gen12. "There is an important performance monitoring fix (#6333), more resiliency to pcode load delay and avoiding caching problems on LLC systems for ring buffers. Intel Linux engineer Joonas Lahtinen summed up this week's drm-intel-gt-next pull as: Much of Intel's open-source Linux graphics focus recently has been on readying their Meteor Lake graphics support as well as preparing for their new "Xe" kernel driver that has yet to be mainlined. Nothing too incredibly exciting for end-users this week, but there still is a few more weeks for more DRM feature code to be readied for DRM-Next to make it for Linux 6.4. This week's Intel GT changes include a number of fixes, avoiding use of stolen memory or BAR for ring buffers on LLC platforms, continued enablement around Intel Meteor Lake (MTL) graphics, various DG2/Alchemist tweaks, and other routine work. This week another batch of "drm-intel-gt-next" material was submitted. Last week following the Linux 6.3-rc1 release Intel engineers already began sending new Intel i915 driver feature code to DRM-Next for queuing until the Linux 6.4 merge window in early May.
