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 <james.clark@arm.com> Signed-off-by: Lexi Shao <shaolexi@huawei.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexei Starovoitov <ast@kernel.org> Cc: Andrii Nakryiko <andrii@kernel.org> Cc: Daniel Borkmann <daniel@iogearbox.net> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jessica Yu <jeyu@kernel.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: John Fastabend <john.fastabend@gmail.com> Cc: KP Singh <kpsingh@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Martin KaFai Lau <kafai@fb.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Nathan Chancellor <natechancellor@gmail.com> Cc: Nick Desaulniers <ndesaulniers@google.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: QiuXi <qiuxi1@huawei.com> Cc: Song Liu <songliubraving@fb.com> Cc: Wangbing <wangbing6@huawei.com> Cc: Xiaoming Ni <nixiaoming@huawei.com> Cc: Yonghong Song <yhs@fb.com> Cc: bpf@vger.kernel.org Cc: clang-built-linux@googlegroups.com Link: https://lore.kernel.org/r/20211029065038.39449-2-shaolexi@huawei.comSigned-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

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 <kim.phillips@amd.com> Signed-off-by: Ravi Bangoria <ravi.bangoria@amd.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lore.kernel.org/lkml/20211103072112.32312-1-ravi.bangoria@amd.comSigned-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

Namhyung Kim authored
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.

A table generator for setsockopt is needed, probably will be done in the 5.16 cycle.

In commit 2214c0e7 ("parisc: Move thread_info into task struct") PA-RISC gained support for THREAD_INFO_IN_TASK while changes were already underway to keep the CPU field in thread_info rather than move it into task_struct when THREAD_INFO_IN_TASK is enabled. The result is a broken build for all PA-RISC configs that enable SMP. So let's partially revert that commit, and get rid of the ugly hack to get at the offset of task_struct::cpu without having to include linux/sched.h, and put the CPU field back where it was before.

I no longer think interrupts can be disabled in the futex and cmpxchg operations because of COW breaks. This not ideal but I suspect it's the best we can do. For the cmpxchg operations in syscall.S, we rely on the code to not schedule off the gateway page. For the futex, I added code to disable preemption. So far, I haven't seen the warnings with the attached change but the change is only lightly tested. Signed-off-by: Dave Anglin <dave.anglin@bell.net> Signed-off-by: Helge Deller <deller@gmx.de>
