powerpc/perf: Add support for the hv 24x7 interface This provides a basic interface between hv_24x7 and perf. Similar to the one provided for gpci, it lacks transaction support and does not list any events. Example usage via perf tool: perf stat -e 'hv_24x7/domain=2,offset=8,starting_index=0,lpar=0xffffffff/' -r 0 -C 0 -x ' ' sleep 0.1 Signed-off-by: Cody P Schafer <cody@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
