Intel graphics driver engineers today sent out their first batch of feature updates to DRM-Next for queuing ahead of the next Linux 6.16 kernel cycle.
Included as part of this first batch of intel-drm-next updates intended for the Linux 6.16 kernel is a big refactoring to the Variable Refresh Rate (VRR) code. The VRR code for the Intel open-source graphics driver is now much improved with various bug fixes and enhancements compared to on prior kernel versions. Separately this pull also has more Xe3LPD updates with continuing to get the display enablement brought-up for the next-gen Panther Lake SoCs with Xe3 integrated graphics.
There are also other bug fixes and enhancements as outlined in today’s pull request:
It is worth to highlight the huge amount of patches around VRR refactor. Also more chunks of clean-up towards a separated display. And finally some changes in the debugfs entries.

– Updates for xe3lpd display
– Fix link training interrupted by HPD pulse
– Watermark bound checks for DSC
– VRR Refactor and other fixes and improvements
– More conversions towards intel_display struct
– Other clean-up patches towards a display separation
