Compatibility of pcm-pcie Utility with Different Intel CPUs – Issues with 12th Gen i7-12700

[thenveerpk]

Hi Team ,

I am encountering the following error while running the pcm-pcie utility on my system:

Detected 12th Gen Intel(R) Core(TM) i7-12700 "Intel(r) microarchitecture codename Alder Lake" stepping 2 microcode level 0x3a
Jaketown, Ivytown, Haswell, Broadwell-DE, Skylake, Icelake, Snowridge and Sapphirerapids Server CPU is required for this tool! Program aborted
Cleaning up
Closed perf event handles
Zeroed uncore PMU registers

Below i am giving my cpu information :

CPU: Intel® Core™ i7-12700 (12th Gen, Alder Lake)
Logical cores: 20
Physical cores: 12
Max frequency: 4.9 GHz
Architecture: x86_64
Linux Distribution: (e.g., Ubuntu 20.04 or other)

Is it possible to use pcm-pcie with newer Intel CPUs like the 12th Gen Alder Lake or later (e.g., Raptor Lake, Meteor Lake)?
If not supported currently, is there any patch or alternative solution available to enable PCIe bandwidth monitoring on these CPUs?

Hi, unfortunately we can't support this. This is documented here: https://github.com/intel/pcm/blob/master/doc/FAQ.md#q12
