https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=196093 --- Comment #15 from Conrad E. Meyer <cem@freebsd.org> --- Fwiw, the guest is attempting to configure Enhanced SpeedStep after detecting the host as SandyBridge{,-E} or IveBridge{,-E}. We are setting the SS_ENABLE bit and TB_DISABLE bits of IA32_MISC_ENABLE. Finally, we also write the IA32_PERF_CTL register (haven't gotten that far in boot yet, don't know if Bhyve handles that or not. Pretty much all of these should just be ignored rather than trapping, IMO. -- You are receiving this mail because: You are the assignee for the bug.
