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.
Hi Stephane,
The link for the oprofile user-space patch is:
ftp://ftp.hpl.hp.com/pub/linux-ia64/oprof-perfmon2-070122.diff
I am looking through the oprofile user-space patch. It would probably be wiser
to make the patch apply to the oprofile cvs repository.
-The oprofile cvs repository doesn't have Makefile.in, but the changes will need
to be placed in the configure.in and Makefile.am files. The patch shouldn't be
touching Makefile.in.
Did the patch mean to remove oprofile-0.9.2/doc/oprofile.1?
Did the patched code compile with -Wall? When building I see:
gcc -DHAVE_CONFIG_H -I. -I.. -I ../libabi -I ../libutil -I ../libop -I ../libdb
-DOPROF_PERFMON2 -W -Wall -fno-common -Wdeclaration-after-statement -Werror
-fno-omit-frame-pointer -g -O2 -MT opd_perfmon_22.o -MD -MP -MF
.deps/opd_perfmon_22.Tpo -c -o opd_perfmon_22.o opd_perfmon_22.c
cc1: warnings being treated as errors
opd_perfmon_22.c: In function ‘do_load_context’:
