    alpha: implement HW performance events on the EV67 and later CPUs · 979f8671
    Michael Cree 提交于
    This implements hardware performance events for the EV67 and later CPUs
    within the Linux performance events subsystem.  Only using the performance
    monitoring unit in HP/Compaq's so called "Aggregrate mode" is supported.
    
    The code has been implemented in a manner that makes extension to other
    older Alpha CPUs relatively straightforward should some mug wish to
    indulge themselves.
