Hello,
I am new to the powerpc architecture and I am trying to use
perf_event_open() system call for power pc architecture (e500mc) using
2.6.32 kernel distribution. Is this system call number supported for power
pc architecture? If yes, is there something similar to
arch/x86/kernel/syscall_table_32.S listing for powerpc that indicates the
number for the above system call?
Thanks in advance for assisting me. Please email me at

Yep e500mc supports performance counters in hardware. Found the mapping for
the kernel call in /arch/powerpc/include/asm/systbl.h

perf event support for e500mc wasn't added until 2.6.34.
