Hi,
I can't seem to get oprofile (0.9.2) working with current rc kernels an my AMD64 platform. All works out of the box with 2.6.18 and earlier.
LC_ALL=C opcontrol -s /usr/bin/opcontrol: line 994: /dev/oprofile/0/enabled: No such file or directory /usr/bin/opcontrol: line 994: /dev/oprofile/0/event: No such file or directory /usr/bin/opcontrol: line 994: /dev/oprofile/0/count: No such file or directory /usr/bin/opcontrol: line 994: /dev/oprofile/0/kernel: No such file or directory /usr/bin/opcontrol: line 994: /dev/oprofile/0/user: No such file or directory /usr/bin/opcontrol: line 994: /dev/oprofile/0/unit_mask: No such file or directory Using 2.6+ OProfile kernel interface. Using log file /var/lib/oprofile/oprofiled.log Daemon started. Profiler running.

So why isn't there a "0" directory?
If I try to use 1 by setting
CHOSEN_EVENTS_1=CPU_CLK_UNHALTED:100000:0:1:1 NR_CHOSEN=1
in daemonrc, I get:
No events given.
Am I doing something wrong or had the rc kernel something changed so that I need trunk version of oprofile? Or is something broken in kernel module?
