Pull up following revision(s) (requested by msaitoh in ticket #367):
sys/arch/x86/x86/procfs_machdep.c: revision 1.20
sys/arch/x86/x86/procfs_machdep.c: revision 1.17
sys/arch/x86/x86/procfs_machdep.c: revision 1.18
Print the following cpuid bits:
0x0000000d:1 eax (xsaveopt, xsavec, xgetbv1, xsaves)
0x0000000f:0 edx (cqm_llc)
0x0000000f:1 edx (cqm_occup_llc)
0x00000006 eax (dtherm, ida, arat, pln, pts, hwp, hwp_notify,
hwp_act_window, hwp_epp, hwp_pkg_req)
- Use per cpu ci->ci_max_cupid instead of global "cpuid_level" variable.
- Print AMD specific cpuid leafs:
0x80000008 ebx
0x8000000a edx
0x80000007 ebx
Fix the location of AMD's smca(Scalable MCA) bit. Thanks Yasushi Oshima for
finding this bug.
