Subject: 2.6.19-rc* and oprofile issues - msg#00091List: linux.oprofile
by Date: Prev Next Date Index by Thread: Prev Next Thread Index
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. ll /dev/oprofile/ insgesamt 0 drwxr-xr-x 1 root root 0 27. Okt 06:06 1 drwxr-xr-x 1 root root 0 27.

Okt 06:06 stats 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? dmesg + .config http://www.prakash.gmxhome.de/linux/2.6.19-rc1-4.txt.bz2 cat /proc/interrupts for 2.6.19-rc1 http://www.prakash.gmxhome.de/linux/irqs19.txt lspci can be found here: http://marc.theaimsgroup.com/?l=linux-kernel&m=115545986619977&w=2 Cheers, -- (Â= =Â) //\ Prakash Punnoor /\\ V_/ \_V
