Linux 7.0 Adds Support for Intel DSA 3.0 and New L2 Cache Metrics
Linux 7.0 includes initial preparations for Intel’s DSA 3.0 accelerators, enabling data movement and transformation tasks on Xeon processors with new sysfs interfaces and SGL size support. Additionally, the Turbostat utility now reports new L2 cache metrics such as L2MRPS and L2%hit for recent Intel processors including Xeon Sapphire Rapids, Atom Gracemont, and Alder Lake, thanks to updated performance counters in the kernel. These enhancements improve user-space visibility of hardware capabilities, despite some deviations from standard Linux kernel practices.
