2021-11-07perf symbols: Ignore $a/$d symbols for ARM modulesLexi Shao1-0/+4
On anARM machine, kernel symbols from modules can be resolved to $a instead of printing the actual symbol name. Ignore symbols starting with "$" when building kallsyms rbtree. A sample stacktrace is shown as follows: c0f2e39c schedule_hrtimeout+0x14 ([kernel.kallsyms]) bf4a66d8 $a+0x78 ([test_module]) c0a4f5f4 kthread+0x15c ([kernel.kallsyms]) c0a001f8 ret_from_fork+0x14 ([kernel.kallsyms]) On an ARM machine, $a/$d symbols are used by the compiler to mark the beginning of code/data part in code section. These symbols are filtered out when linking vmlinux(see scripts/kallsyms.c ignored_prefixes), but are left on modules. So there are $a symbols in /proc/kallsyms which share the same addresses with the actual module symbols and confuses perf when resolving symbols. After this patch, the module symbol name is printed: c0f2e39c schedule_hrtimeout+0x14 ([kernel.kallsyms]) bf4a66d8 test_func+0x78 ([test_module]) c0a4f5f4 kthread+0x15c ([kernel.kallsyms]) c0a001f8 ret_from_fork+0x14 ([kernel.kallsyms]) Reviewed-by: James Clark <[email protected]> Signed-off-by: Lexi Shao <[email protected]> Cc: Alexander Shishkin <[email protected]> Cc: Alexei Starovoitov <[email protected]> Cc: Andrii Nakryiko <[email protected]> Cc: Daniel Borkmann <[email protected]> Cc: Ingo Molnar <[email protected]> Cc: Jessica Yu <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: John Fastabend <[email protected]> Cc: KP Singh <[email protected]> Cc: Mark Rutland <[email protected]> Cc: Martin KaFai Lau <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Nathan Chancellor <[email protected]> Cc: Nick Desaulniers <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: QiuXi <[email protected]> Cc: Song Liu <[email protected]> Cc: Wangbing <[email protected]> Cc: Xiaoming Ni <[email protected]> Cc: Yonghong Song <[email protected]> Cc: [email protected] Cc: [email protected] Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
2021-11-07perf evsel: Don't set exclude_guest by defaultRavi Bangoria3-5/+31
Perf tool sets exclude_guest by default while calling perf_event_open(). Because IBS does not have filtering capability, it always gets rejected by IBS PMU driver and thus perf falls back to non-precise sampling. Fix it by not setting exclude_guest by default on AMD. Before: $ sudo ./perf record -C 0 -vvv true |& grep precise precise_ip 3 decreasing precise_ip by one (2) precise_ip 2 decreasing precise_ip by one (1) precise_ip 1 decreasing precise_ip by one (0) After: $ sudo ./perf record -C 0 -vvv true |& grep precise precise_ip 3 decreasing precise_ip by one (2) precise_ip 2 Committer notes: Fixup init to zero for perf_env in older compilers: arch/x86/util/evsel.c:15:26: error: missing field 'os_release' initializer [-Werror,-Wmissing-field-initializers] struct perf_env env = {0}; ^ Committer notes: Namhyung remarked: It'd be nice if it can cover explicit "-e cycles:pp" as well. Ravi clarified: For explicit :pp modifier, evsel->precise_max does not get set and thus perf does not try with different attr->precise_ip values while exclude_guest set. So no issue with explicit :pp: $ sudo ./perf record -C 0 -e cycles:pp -vvv |& grep "precise_ip\|exclude_guest" precise_ip 2 exclude_guest 1 precise_ip 2 exclude_guest 1 switching off exclude_guest, exclude_host precise_ip 2 ^C Also, with :P modifier, evsel->precise_max gets set but exclude_guest does not and thus :P also works fine: $ sudo ./perf record -C 0 -e cycles:P -vvv |& grep "precise_ip\|exclude_guest" precise_ip 3 decreasing precise_ip by one (2) precise_ip 2 ^C Reported-by: Kim Phillips <[email protected]> Signed-off-by: Ravi Bangoria <[email protected]> Acked-by: Namhyung Kim <[email protected]> Tested-by: Arnaldo Carvalho de Melo <[email protected]> Cc: Andi Kleen <[email protected]> Cc: Ian Rogers <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Stephane Eranian <[email protected]> Link: http://lore.kernel.org/lkml/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
2021-11-06perf evsel: Fix missing exclude_{host,guest} settingNamhyung Kim4-5/+42
The current logic for the perf missing feature has a bug that it can wrongly clear some modifiers like G or H. Actually some PMUs don't support any filtering or exclusion while others do. But we check it as a global feature. For example, the cycles event can have 'G' modifier to enable it only in the guest mode on x86. When you don't run any VMs it'll return 0. # perf stat -a -e cycles:G sleep 1 Performance counter stats for 'system wide': 0 cycles:G 1.000721670 seconds time elapsed But when it's used with other pmu events that don't support G modifier, it'll be reset and return non-zero values. # perf stat -a -e cycles:G,msr/tsc/ sleep 1 Performance counter stats for 'system wide': 538,029,960 cycles:G 16,924,010,738 msr/tsc/ 1.001815327 seconds time elapsed This is because of the missing feature detection logic being global. Add a hashmap to set pmu-specific exclude_host/guest features. Committer notes: Fix 'perf test python' by adding a stub for evsel__find_pmu() in tools/perf/util/python.c, document that it is used so far only for the above reasons so that if anybody needs this in the python binding usecases, we can revisit this.
