Intel Nova Lake Power Management Bits Prepped Ahead Of Linux 6.19
Intel engineers continue working on the Nova Lake next-gen processor enablement for the Linux kernel. In addition to the Intel Xe3P graphics and other early Nova Lake enablement work already queued in "-next" Git branches ahead of the Linux 6.19 merge window, the initial power management code is also ready for this next kernel cycle.
The initial Intel Nova Lake power management bits are set to premiere in the Linux 6.19 kernel now that the patches have worked their way into the power management subsystem's "linux-next" branch of linux-pm.git.
This initial work includes int340x thermal driver support with adding Nova Lake H and Nova Lake S IDs to that processor thermal device driver. The same features as Arrow Lake, Lunar Lake, and Panther Lake are supported for this driver addition with just the new IDs added.
The int340x driver has another addition for enabling the Digital Linear Voltage Regulator (DLVR) support for Nova Lake.
There is also DPTF support for Nova Lake as another patch on the way for Linux 6.19. That is for the Intel Dynamic Platform and Thermal Framework integration with the Linux kernel. Again, just new device IDs are needed with no other fundamental differences compared to Panther Lake.
The Linux 6.19 merge window is beginning in early December while the stable kernel will be out in February with these initial Nova Lake enablement pieces. With Nova Lake processors not expected until at least late 2026, there still are a few more kernel cycles to get all of the open-source driver support squared away for the exciting Intel Nova Lake hardware.
