The selectors are c001000-c001003, and the counters are c001004-c001007. I've verified that the MSRs are there and working by manually setting the MSRs with msr-tools to count cycles. - -The processor does not support the extended perfctr or the perfctr_nb. These are in cpuid leaf 8000_0001. Qemu also sees that these cpuid flags are not set, when I try launching with -cpu host,perfctr_core,check. However, this flag is only for the extended perfctr MSRs, which also happen to map the original four counters at c0010200. - -When I run a Guest OS, that OS is unable to use the perf counter registers from c001000-7. rdmsr and wrmsr complete, but the results are always 0. By contrast, a wrmsr to one of the c0010200 registers causes a general protection fault (as it should, since those aren't supported). - -Kernel: 3.14.0-gentoo -Qemu: 2.0.0 (gentoo) and also with 2.0.50 (commit 06b4f00d5) -Qemu command: qemu-system-x86_64 -enable-kvm -cpu host -smp 8 -m 1024 -nographic -monitor /dev/pts/4 mnt/hdd.img -cat /proc/cpuinfo: -processor : 3 -vendor_id : AuthenticAMD -cpu family : 16 -model : 4 -model name : AMD Phenom(tm) II X4 965 Processor -stepping : 3 -cpu MHz : 800.000 -cache size : 512 KB -physical id : 0 -siblings : 4 -core id : 3 -cpu cores : 4 -apicid : 3 -initial apicid : 3 -fpu : yes -fpu_exception : yes -cpuid level : 5 -wp : yes -flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow constant_tsc rep_good nopl nonstop_tsc extd_apicid pni monitor cx16 popcnt lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs skinit wdt hw_pstate npt lbrv svm_lock nrip_save -bogomips : 6803.79 -TLB size : 1024 4K pages -clflush size : 64 -cache_alignment : 64 -address sizes : 48 bits physical, 48 bits virtual -power management: ts ttp tm stc 100mhzsteps hwpstate - -thanks. \ No newline at end of file |
