AMD released its latest PMC (power management controller) driver patches for the Linux kernel, which reference a yet unreleased "Family 1Ah" processors. Phoronix believes this is the first reference to AMD's next generation "Zen 5" microarchitecture in the PMC driver. We've already seen AMD EPYC "Turin" server processors based on "Zen 5" in the flesh, and it's likely that AMD is handing these out to some of its biggest data-center customers for testing and evaluation, before giving them some final touches and green-lighting mass-production in 2024. The patches themselves are barely two new lines of code, and talk about a new sleep state called "s2idle." This is a software-defined system sleep state. The EPYC "Turin" processor comes in two packages, one with up to 128 "Zen 5" cores, and another with up to 192 "Zen 5c" cores for cloud applications.
