perf report: Add support for PERF_SAMPLE_CODE_PAGE_SIZE
Add a new sort dimension "code_page_size" for common sort. With this option applied, perf can sort and report by sample's code page size. For example: # perf report --stdio --sort=comm,symbol,code_page_size # To display the perf.data header info, please use # --header/--header-only options. # # # Total Lost Samples: 0 # # Samples: 3K of event 'mem-loads:uP' # Event count (approx.): 1470769 # # Overhead Command Symbol Code Page Size IPC [IPC Coverage] # ........ ....... ............................ .............. .................... # 69.56% dtlb [.] GetTickCount 4K - - 17.93% dtlb [.] Calibrate 4K - - 11.40% dtlb [.] __gettimeofday 4K - - # Signed-off-by: Stephane Eranian <eranian@google.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: Andi Kleen <ak@linux.intel.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Michael Ellerman <mpe@ellerman.id.au> Cc: Will Deacon <will@kernel.org> Link: https://lore.kernel.org/r/20210105195752.43489-6-kan.liang@linux.intel.com Signed-off-by: Kan Liang <kan.liang@linux.intel.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
