AMD Releases Linux Patch for 96 Core Zen 4 Epyc Genoa Processors

AMD simply launched the primary Linux kernel patch to permit monitoring of its next-gen Epyc Genoa server processors. The 4th Gen Epyc chips will characteristic a complete of as much as 96 cores throughout 12 CCDs. At current, the k10temp Linux driver for temperature monitoring of AMD CPUs can learn a complete of as much as eight CCDs or 64 cores, making it essential to replace the kernel to help the newer processors.

The most recent Linux patch explicitly says: “The newer AMD Household 19h Fashions 10h-1Fh and A0h-AFh can help as much as 12 CCDs. Replace the motive force to learn as much as 12 CCDs.

The AMD Household 19h fashions symbolize the next-gen Zen 4 processors. Along with confirming the general core depend of 96 for Genoa, this additionally signifies that the general CCD construction will stay unchanged with Zen 4. We are going to, as soon as once more, be seeing eight-core chiplets, and a complete of as much as 24 cores or 3 CCDs for the desktop Zen 4 Ryzen lineup.

AMD’s Bergamo processors that includes the Zen 4c cores are slated to reach a couple of quarters after Genoa. They’ll characteristic as much as 128 cores, and extra reminiscence channels in comparison with Genoa. Moreover, they’ll doubtless characteristic sixteen core CCDs [not confirmed], leading to an general CCD depend of 8. The L3 cache can be trimmed to create space for the extra cores.

That includes the Zen 4 structure, and TSMC’s N5 (5nm EUV) course of node, the next-gen Ryzen/Epyc lineups are slated to reach within the second half of 2022
