perf/x86/intel: Add mem-loads/stores support for Haswell
mem-loads is basically the same as Sandy Bridge, but we use a separate string for changes later. Haswell doesn't support the full precise store mode, so we emulate it using the "DataLA" facility. This allows to do everything, but for data sources we can only detect L1 hit or not. There is no explicit enable bit anymore, so we have to tie it to a perf internal only flag. The address is supported for all memory related PEBS events with DataLA. Instead of only logging for the load and store events we allow logging it for all (it will be simply 0 if the current event does not support it) Signed-off-by: Andi Kleen <ak@linux.intel.com> Cc: Andi Kleen <ak@linux.jf.intel.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Link: http://lkml.kernel.org/r/1371515812-9646-7-git-send-email-andi@firstfloor.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
