perf bench numa: Add more comment for -c option (2017-03-06 12:39:30 -0300)
perf/core improvements and fixes:
New features:
- Allow sorting by symbol_size in 'perf report' and 'perf top' (Charles Baylis)
E.g.:
# perf report -s symbol_size,symbol
Samples: 9K of event 'cycles:k', Event count (approx.): 2870461623
Overhead Symbol size Symbol
14.55% 326 [k] flush_tlb_mm_range
7.20% 1045 [k] filemap_map_pages
5.82% 124 [k] vma_interval_tree_insert
5.18% 2430 [k] unmap_page_range
2.57% 571 [k] vma_interval_tree_remove
1.94% 494 [k] page_add_file_rmap
1.82% 740 [k] page_remove_rmap
1.66% 1017 [k] release_pages
1.57% 1636 [k] update_blocked_averages
1.57% 76 [k] unlock_page
- Add support for -p/--pid, -a/--all-cpus and -C/--cpu in 'perf ftrace'
(Namhyung Kim)
Change in behaviour:
- Make system wide (-a) the default option if no target was specified and one
of following conditions is met:
- No workload specified (current behaviour)
- A workload is specified but all requested events are system wide ones,
like uncore ones. (Jiri Olsa)
Fixes:
- Add missing initialization to the instruction decoder used in the
intel PT/BTS code, which was causing lots of failures in 'perf test',
looking for a value when there was none (Adrian Hunter)
Infrastructure:
- Add arch code needed to adopt the kernel's refcount_t to aid in
catching bugs when using atomic_t as a reference counter, basically
cmpxchg related functions (Arnaldo Carvalho de Melo)
- Convert the code using atomic_t as reference counts to refcount_t
(Elena Rashetova)
- Add feature test for sched_getcpu() to more easily check for its
presence in the many libc implementations and accross different
versions of such C libraries (Arnaldo Carvalho de Melo)
- Issue a HW watchdog disable hint in 'perf stat' for when some of the
requested events can't get counted because a PMU counter is taken by that
watchdog (Borislav Petkov).
- Add mapping for Intel's KnightsMill PMU events (Karol Wachowski)
Documentation:
- Clarify the term 'convergence' in:
perf bench numa numa-mem -h --show_convergence (Jiri Olsa)
Kernel code:
- Ensure probe location is at function entry in kretprobes (Naveen N. Rao)
- Allow return probes with offsets and absolute addresses (Naveen N. Rao)

This makes, among other cases, the previous new feature (perf stat --per-thread for system wide, albeit that not seeming to be the motivation for this patch) more robust. (Mengting Zhang) - Generate s390 syscall table from asm/unistd.h, doing like x86, removing the dependency on audit-libs to do this id->string translation, speeding up the support for newly introducted syscalls (Hendrik Brueckner) - Fix 'perf test' on filesystems where readdir() returns d_type == DT_UNKNOWN, such as XFS (Jiri Olsa) - Fix PERF_SAMPLE_RAW_DATA endianity handling for cross-arch tracepoint processing (Jiri Olsa) - Add __return suffix for return events in 'perf probe', streamlining entry/exit tracing (Masami Hiramatsu) - Improve support for versioned symbols in 'perf probe" (Masami Hiramatsu) - Clarify error message about invalid 'perf probe' event names (Masami Hiramatsu) - Fix check open filename arg using 'perf trace' in a 'perf test' entry for systems using glibc >= 2.26, such as some ARM and s390 distros (Michael Petlan) - Make method for obtaining the (normalized) architecture id for a perf.data file or for the running system used by the annotation routines generally available, next user will be for generating per arch errno string tables to allow for pretty printing errno codes recorded in a perf.data file in architecture A to be properly decoded on hardware archictecture B. (Arnaldo Carvalho de Melo) - Remove duplicate includes, found using scripts/checkincludes.pl (Pravin Shedge) - s390 needs -fPIC, enable it, also revert a patch that supposedly did that but instead enabled -fPIC for x86 (Hendrik Brueckner, Arnaldo Carvalho de Melo) Signed-off-by: Arnaldo Carvalho de Melo Arnaldo Carvalho de Melo (4): perf annotate: Get the cpuid from evsel->evlist->env in symbol__annotate() perf annotate: Use perf_env when obtaining the arch name perf env: Adopt perf_env__arch() from the annotate code Revert "perf s390: Always build with -fPIC" Hendrik Brueckner (4): tools include s390: Grab a copy of arch/s390/include/uapi/asm/unistd.h perf s390: Generate system call table from asm/unistd.h perf trace: Use generated syscall table on s390 too perf s390: Always
