Linux 6.17 Readies EDAC Support For Intel Granite Rapids D, Wildcat Lake, Raptor Lake HX
In addition to Intel preparing Bartlett Lake S EDAC driver support for Linux 6.17, several other recent and upcoming Intel processors are also set to see Error Detection and Correction (EDAC) driver coverage with this next version of the Linux kernel.
Wildcat Lake has been seeing a lot of Linux patches recently for this low-power processor series rumored to be the successor to Alder Lake N. The latest on the Wildcat Lake enablement side for Linux is Wildcat Lake SoC support in the iGen6 EDAC driver. The patch reinforces what was presented in other Linux patches that Wildcat Lake is a mobile derivative of Panther Lake. The EDAC patch confirms one memory controller for Wildcat Lake and the same registers as Meteor Lake P from this error detection and correction side. This EDAC support makes use of the hardware's in-band ECC capability.
Also queued this week was Raptor Lake HX support being added to the ie31200 EDAC driver. The few lines of code there enables the Raptor Lake HX's out-of-band ECC capability.
The other new Intel EDAC driver code readied this week for Linux 6.17 is Granite Rapids D support for the i10nm EDAC driver. Granite Rapids D uses similar memory controller registers to Granite Rapids server CPUs but with a different memory controller MMIO base address. EDAC support now ready for Intel Granite Rapids D with the upcoming Linux 6.17 cycle.
A lot of new hardware support and feature code is brewing for Linux 6.17. The merge window should be open by early August while the stable kernel will be out by early October.
