https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D268943 Mitchell Horne <mhorne@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|Open |In Progress CC| |mhorne@freebsd.org Assignee|bugs@FreeBSD.org |mhorne@freebsd.org --- Comment #1 from Mitchell Horne <mhorne@freebsd.org> --- It appears that bhyve does not support virtualized performance counters, neither on AMD or Intel. Thus, the assertion is triggered because reading t= he counter configuration register will always return a value of zero. The AMD hwpmc class should detect when this support is disabled and bail fr= om the initialization routine. I will work on this change. --=20 You are receiving this mail because: You are the assignee for the bug.=
