Hi Stephane,
We need read some uncore performance counters by using "perf" from Xeon
E5-2660 processor (family 6, model 45), we installed the libpfm-4.4.0.
However the UNC_xxx events didn't show up. Here's the log I got by running
example/check_events - it seems it detected those uncore events
Detected PMU models:
[18, ix86arch, "Intel X86 architectural PMU"]
[51, perf, "perf_events generic PMU"]
[71, snb_ep, "Intel Sandy Bridge EP"]
[80, snbep_unc_cbo0, "Intel Sandy Bridge-EP C-Box 0 uncore"]
[81, snbep_unc_cbo1, "Intel Sandy Bridge-EP C-Box 1 uncore"]
[82, snbep_unc_cbo2, "Intel Sandy Bridge-EP C-Box 2 uncore"]
[83, snbep_unc_cbo3, "Intel Sandy Bridge-EP C-Box 3 uncore"]
[84, snbep_unc_cbo4, "Intel Sandy Bridge-EP C-Box 4 uncore"]
[85, snbep_unc_cbo5, "Intel Sandy Bridge-EP C-Box 5 uncore"]
[86, snbep_unc_cbo6, "Intel Sandy Bridge-EP C-Box 6 uncore"]
[87, snbep_unc_cbo7, "Intel Sandy Bridge-EP C-Box 7 uncore"]
[88, snbep_unc_ha, "Intel Sandy Bridge-EP HA uncore"]
[89, snbep_unc_imc0, "Intel Sandy Bridge-EP IMC0 uncore"]
[90, snbep_unc_imc1, "Intel Sandy Bridge-EP IMC1 uncore"]
[91, snbep_unc_imc2, "Intel Sandy Bridge-EP IMC2 uncore"]
[92, snbep_unc_imc3, "Intel Sandy Bridge-EP IMC3 uncore"]
[93, snbep_unc_pcu, "Intel Sandy Bridge-EP PCU uncore"]
[94, snbep_unc_qpi0, "Intel Sandy Bridge-EP QPI0 uncore"]
[95, snbep_unc_qpi1, "Intel Sandy Bridge-EP QPI1 uncore"]
[96, snbep_unc_ubo, "Intel Sandy Bridge-EP U-Box uncore"]
[97, snbep_unc_r2pcie, "Intel Sandy Bridge-EP R2PCIe uncore"]
[98, snbep_unc_r3qpi0, "Intel Sandy Bridge-EP R3QPI0 uncore"]
[99, snbep_unc_r3qpi1, "Intel Sandy Bridge-EP R3QPI1 uncore"]
Total events: 3073 available, 663 supported
Requested Event: PERF_COUNT_HW_CPU_CYCLES
Actual Event: perf::PERF_COUNT_HW_CPU_CYCLES
PMU : perf_events generic PMU
IDX : 106954752
Codes : 0x0
Requested Event: PERF_COUNT_HW_INSTRUCTIONS
Actual Event: perf::PERF_COUNT_HW_INSTRUCTIONS
PMU : perf_events generic PMU
IDX : 106954755
Codes : 0x1
However the "perf list" only shows "pre-defined", "ix86arch", and "snb_ep".
Can you tell from the above information what would be like the problem? The
kernel version is 3.2.37-94
Thanks and appreciate!
Qingyuan
