Linux 7.4 Fixes AMD CPU TLB Size Reporting for Zen 5 and Newer

{"heading_1":"Background on TLB Size Reporting","content_1":"TLB (Translation Lookaside Buffer) size reporting is a critical aspect of CPU performance monitoring. The Linux kernel previously under-reported TLB sizes for AMD Zen 5 and newer processors, leading to inaccuracies in system monitoring.","content_2":"The issue stems from a change in how AMD Zen 5 and newer processors report TLB sizes, which are now multiples of 32. The Linux kernel was not adapted to this change, resulting in under-reporting.","content_3":"The fix in Linux 7.4 ensures that the correct TLB sizes are conveyed via /proc/cpuinfo and similar interfaces, providing accurate information to users and system administrators."}
