Linux 7.3 now supports per-CCD temperature monitoring on AMD EPYC Zen 5 processors, a crucial update for system administrators managing these servers. This enhancement addresses previous monitoring gaps in EPYC 9005 series.
Linux 7.3 has introduced a significant update for system administrators and engineers managing AMD EPYC Zen 5 processors. The latest kernel now supports per-CCD temperature monitoring for these processors, a feature that was notably absent until now. This update, part of the k10temp driver enhancements, resolves prior limitations in monitoring the EPYC 9005 series, which was hampered by their higher number of maximum CCDs and the need for expanded model range checks.
For those managing EPYC Turin (Zen 5) server processors, this improvement brings parity with AMD Ryzen client processors, which already benefited from per-CCD temperature monitoring. This enhancement is critical for maintaining optimal performance and preventing thermal issues in large-scale server deployments.
The Linux 7.3 kernel also brings a host of other hardware monitoring updates. The ASUS EC Sensors driver now supports additional Intel and AMD desktop motherboards, including models like the ROG STRIX Z390-E GAMING and the ROG Maximus Z790 Hero. Additionally, the asus_rog_ryujin driver has expanded its support to include the ROG Ryujin III liquid cooling product, while the NZXT-Kraken3 driver now accommodates the NZXT Kraken 2024 Elite.
Lenovo systems receive a boost too, with the Yogafan driver now supporting models such as the Lenovo LOQ 15IAX9 and the Yoga Pro 7 14IAH10. Moreover, new drivers have been introduced for the PolarFire SoC and the RISC-V Eswin EIC7700 PVT sensor, broadening the scope of Linux hardware monitoring capabilities.
This update is a solid improvement for Linux engineers, especially those managing EPYC Zen 5 servers. It enhances monitoring precision and ensures that administrators can keep a closer eye on the thermal performance of their hardware, ultimately aiding in better system management and reliability.
