[BUG] "No events given." Problem of opcontrol or ophelp?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi, all,

I tried with oprofile 0.9.1 and 0.9.2 both with a existing setup file /root/.oprofile/daemonrc,
CHOSEN_EVENTS[0]=PM_BR_UNCOND_GRP43:500000:0:1:1
CHOSEN_EVENTS[1]=PM_BR_PRED_TA_GRP43:500000:0:1:1
CHOSEN_EVENTS[2]=PM_BR_PRED_CR_GRP43:500000:0:1:1
CHOSEN_EVENTS[3]=PM_BR_PRED_CR_TA_GRP43:500000:0:1:1
CHOSEN_EVENTS[4]=PM_RUN_INST_CMPL_GRP43:500000:0:1:1
CHOSEN_EVENTS[5]=PM_RUN_CYC_GRP43:500000:0:1:1
NR_CHOSEN=6
SEPARATE_LIB=0
SEPARATE_KERNEL=0
SEPARATE_THREAD=0
SEPARATE_CPU=0
VMLINUX=/boot/vmlinux-2.6.19-rc2-pr28252
IMAGE_FILTER=
CPU_BUF_SIZE=0
CALLGRAPH=0
XENIMAGE=none

But when issue "opcontrol --start", 0.9.1 version will start well, 0.9.2 will complains "No events given."
instead.

Here is the verbose output of 0.9.2 opcontrol,
