Add support for AMD PerfMonV2 (Family 19h+) core counters, which need both the per-counter EVSEL enable bit and the global GLOBAL_CTL bit set to count. Detects PerfMonV2 at init and switches to v2-specific start/stop/interrupt handlers; older CPUs and L3/DF counters keep using the classic path unchanged. Adds a read-only sysctl, kern.hwpmc.amd_perfmon_v2, to report which path is active.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
