I have made available a first draft of the OProfile patch to make it
work on top of perfmon2 on X86 and IA-64 hardware. The current patch
does not take into account unavailable counters.
The patch includes part of your initial oprofile-perfmon2 patch. I have
now split opd_perfmon.c into 3 different files:
- opd_perfmon.c : common perfmon2 front-end
- opd_perfmon_22.c: all arch, perfmon v2.3 support
- opd_perfmon_compat.c: IA-64 only, perfmon v2.0 compatibility
The daemon auto-detects which code to use based on the perfmon version.
To enable perfmon support, you need to run configure with the --enable-perfmon2
option. There is no options to opcontrol, no event table has been modified.
The patch is relative to the oprofile-0.9.2.tar.gz release. You can grab
it at:
ftp://ftp.hpl.hp.com/pub/linux-ia64/oprofile-perfmon2-070622.tar.gz
You need an updated perfmon2 kernel patch to make this work. The kernel
patch is relative to my 061204 kernel perfmon patch and Linux git:
ftp://ftp.hpl.hp.com/pub/linux-ia64/perfmon2-oprof-070122.diff
Let me know what if it works for you.
