perf tools: Add mem access sampling core support
This patch adds the sorting and histogram support functions to enable profiling of memory accesses. The following sorting orders are added: - symbol_daddr: data address symbol (or raw address) - dso_daddr: data address shared object - locked: access uses locked transaction - tlb : TLB access - mem : memory level of the access (L1, L2, L3, RAM, ...) - snoop: access snoop mode Signed-off-by: Stephane Eranian <eranian@google.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung.kim@lge.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1359040242-8269-12-git-send-email-eranian@google.com [ committer note: changed to cope with fc5871ed, the move of methods to machine.[ch], and the rename of dsrc to data_src, to match the change made in the PERF_SAMPLE_DSRC in a previous patch. ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
