Hi again,
Forgot to mention a few things.
Was also changed:
- Intel Core 2 Duo register mapping was changed to be compatible
with that of the Intel architected PMU. Thus you need the new
libpfm from CVS to get working programs.
- APIC programming and PMU acquisition is deferred until
pfm_create_context(). This simplifies the PMU description
modules.
