Hi,
The kernel support for allowing rdpmc is currently broken. Needs to be
fixed. On my list of things to do.

Hi,
I tried perf_examples/self_count.c but it gave segfault in my Core2Duo with
2.6.32 kernel.
I traced the fault and it was because of "rdpmc" instruction.
Program received signal SIGSEGV, Segmentation fault.
0x08049199 in rdpmc (hdr=0xb7fdf000, value=0xbffff790) at self_count.c:79
79 asm volatile("rdpmc" : EAX_EDX_RET(val, low, high) : "c" (counter));
How can i make it work?
Best
