Subject: [PATCH 0/4] perf, amd: Enable AMD family 15h northbridge counters
The following patchset enables 4 additional performance counters in
AMD family 15h processors that counts northbridge events -- such as
DRAM accesses.
This patchset is based on previous work done by Robert Richter
<rric@...nel.org> :
https://lkml.org/lkml/2012/6/19/324
The main differences are:
- The northbridge counters are indexed contiguously right above the
core performance counters.
- MSR address offset calculations are moved to architecture specific
files.
- Interrups are set up to be delivered only to a single core.
