CPU profiling in AMD uProf has the following limitations:

  • CPU profiling expects the profiled application executable binaries must not be compressed or obfuscated by any software protector tools. For example, VMProtect.
  • In case of AMD EPYC™ 1st generation B1 parts, only one PMC register is used at a time for Core PMC event-based profiling (EBP).

IMIX has the following limitations:

  • The IMIX view or report is supported only for IBS profile type.
  • If any module/binary has less than 10 samples, it is not shown in the IMIX report. Extremely less number of samples are not useful for IMIX analysis.
  • Linux kernel module .ko files are not shown in the IMIX view or report.
