Hi all,
I had previously been able to load up the hwpmc module, then take some measurements with pmcstat.
eg:
However when I tried this recently, it appears that BU_CPU_CLK_UNHALTED is no longer available.
now only shows the SOFT counters, and all of the K8 counters are no longer are available.
At the same time, dmesg is spitting out the following:
I don't know if it's related, but there's also a
I'm running 11.3-RELEASE on this machine, which has an Opteron 6366 [same behaviour on a 4365 I also tried]. The K8 functions used to be available, but perhaps something changed in the kernel in the last few months? I build from source, but am using the GENERIC configuration.
The only other thing which may have changed could be a bios setting. Could this have caused this behavior? The only major thing I recall changing recently was ACPI v2.0 -> ACPI v3.0, but I think this was before this problem started occurring.
Thanks for your help
