We're looking for a little quick guidance. We've got a brand new (arrived yesterday) dual Nelalem (Gainestown) blade and are trying to bring up perfmon 2 or 3 on it.
The initial attempt was to build as a module. We used the released /sys/kernel/perfmon/version 2.82. We're running libpfm-3.8 with pfmon-3.8. We see: [r...@hoss linux-2.6.28.9]# /sbin/modprobe perfmon_intel_nhm [r...@hoss linux-2.6.28.9]# pfmon -I <<no output produced>> Concurrent with writing this message, we're rebuilding with perfmon built in, rather than a module, in case that's the issue. (Our other Nehalem was built this way.) If this doesn't work, we'll try the development version out of the GIT repository. Another possibility is that we're out beyond the bleeding edge on this hardware. This is with a stock 2.6.28 kernel from kernel.org. /proc/cpuinfo for core 0 is: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 26 model name : Intel(R) Xeon(R) CPU X5570 @ 2.93GHz stepping : 5 cpu MHz : 2926.064 cache size : 8192 KB physical id : 1 siblings : 4 core id : 0 cpu cores : 4 apicid : 16 initial apicid : 16 fpu : yes fpu_exception : yes cpuid level : 11 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp lm c onstant_tsc arch_perfmon pebs bts rep_good xtopology pni dtes64 monitor ds_cpl v mx est tm2 ssse3 cx16 xtpr pdcm dca sse4_1 sse4_2 lahf_lm ida tpr_shadow vnmi fl expriority ept vpid bogomips : 5852.12 -- Rob -- Robert J.
