[perfmon2] AMD Barcelona IBS

[Vivek T. <vt...@nc...>]

Hi,

I need to program IBS in Barcelona processors. The event I am looking for is
L2  load cache miss and I need the data addresses for such loads.
Can someone point me to some relevant documentation ?

I have a link regarding LWP profiling support of AMD but I guess it is not
yet out.  Here is the link :

http://developer.amd.com/assets/HardwareExtensionsforLightweightProfilingPublic20070720.pdf


Is it significantly different from the current IBS support ?

Also, I have 2.6.23 kernel patched with perfmon. Which libpfm should I use ?
libpfm-3.3 has a sample example for IBS but I am not sure if this is the
best library with the kernel that i have. Please guide.
