Intel Preps Wildcat Lake Display Support For Linux 6.18, "enable_panel_replay" Option
In addition to the Intel Xe kernel graphics driver updates sent out this week in advance of the Linux 6.18 kernel, there was also a batch of drm-intel-next updates also submitted for predominantly display-related changes to the open-source Intel driver.
Notable with the drm-intel-next pull ahead of Linux 6.18 are the patches enabling Wildcat Lake display support. Intel engineers in recent months have been quite busy preparing for Wildcat Lake as a cut-down alternative to upcoming Panther Lake that will be catering to budget laptops/devices. With Linux 6.17 was initial iGPU support for Wildcat Lake while for Linux 6.18 is the enablement patches for actually being able to drive displays.
The drm-intel-next pull this week also includes a number of USB Type-C and DisplayPort code changes, a fix for real-time (PREEMPT_RT) kernels, Panel Self Refresh (PSR) fixes, and other display fixes.
As part of this Intel display work is also introducing a new "enable_panel_replay" module parameter. The "enable_panel_replay" option can be used for enabling or disabling Panel Replay support. By default the per-chip default will be used for Panel Replay while the "enable_panel_replay" option can be used to force enable/disable it. Panel Replay is a display power savings feature that is supported by the Intel Linux driver on recent hardware generations.
