AMD Starts Software Enablement of Zen 5 Processors
According to the Linux Kernel Mailing List, AMD started to enable next-generation processors by submitting patches to the Linux kernel. Codenamed Family 1Ah or Family 26 in decimal notation, the set of patches corresponds to the upcoming AMD Zen 5 core, which is the backbone of the upcoming Ryzen 8000 series processors. The patches have a few interesting notes, namely few of them being: added support for the amd64_edac (Error Detection and Correction) module and temperature monitoring; added PCI IDs for these models covering 00h-1Fh and 20h; added required support in k10temp driver.
The AMD EDAC driver also points out that the Zen 5 server CPUs will max out with 12-channel memory. Codenames 0-31 correspond to next-generation EPYC, while 40 to 79 are desktop and laptop SKUS. Interestingly, these patches are just the start, as adding PCI IDs and temperature drivers are basic enablement. With the 2024 launch date nearing, we expect to see more Linux kernel enablement efforts, especially with more complicated parts of the kernel.
