Hi Stefane, Well, I never ran these test cases before now....
It looks like when I run either rtop or syst, I'm seeing an error because Perfmon2 seems to think that there's other contexts running when in fact there isn't. Something isn't getting cleaned up, because I can increase the number of 'conflicting sessions' simply by running 'self' a number of times. It seems every run increases this value. For example: sicily ~ # dmesg | grep conflict perfmon: pfm_reserve_session.250: CPU0 [2549]: system wide imppossible, 8 conflictingtask_sessions sicily ~ # ~phil/libpfm/examples/self [CP0_25_0(pmc0)=0x18 event_mask=0x0 usr=1 os=0 sup=0 exl=0 int=1] CYCLES [CP0_25_0(pmd0)] [CP0_25_2(pmc1)=0x118 event_mask=0x8 usr=1 os=0 sup=0 exl=0 int=1] INSNS_COMPLETE [CP0_25_2(pmd1)] PMD0 21139069063 CYCLES PMD1 15000092402 INSNS_COMPLETE sicily ~ # ~phil/libpfm/examples/syst pfm_load_context error errno 16 sicily ~ # dmesg | grep conflict perfmon: pfm_reserve_session.250: CPU0 [2563]: system wide imppossible, 9 conflictingtask_sessions Any ideas? Let me know where it should be fixed because I'll fix it in my code base also. Here is more complete log of earlier failures.
