powerpc/perf_counter: Add generic support for POWER-family PMU hardware
This provides the architecture-specific functions needed to access
PMU hardware on the 64-bit PowerPC processors. It has been designed
for the IBM POWER family (POWER 4/4+/5/5+/6 and PPC970) but will
hopefully also suit other 64-bit PowerPC machines (although probably
not Cell given how different it is in this area). This doesn't
include back-ends for any specific processors.
This implements a system which allows back-ends to express the
constraints that their hardware has on what events can be counted
simultaneously. The constraints are expressed as a 64-bit mask +
64-bit value for each event, and the encoding is capable of
expressing the constraints arising from having a set of multiplexers
feeding an event bus, with some events being available through
multiple multiplexer settings, such as we get on POWER4 and PPC970.
Furthermore, the back-end can supply alternative event codes for
each event, and the constraint checking code will try all possible
combinations of alternative event codes to try to find a combination
that will fit.
