2026-02-07perf callchain lbr: Make the leaf IP that of the sampleIan Rogers1-4/+16
The current IP of a leaf function when reported from a perf record with "--call-graph lbr" is the "to" field of the LBR branch stack record. The sample for the event being recorded may be further into the function and there may be inlining information associated with it. Rather than use the branch stack "to" field in this case switch to the callchain appending the sample->ip and thereby allowing the inline information to show. Before this change: ``` $ perf record --call-graph lbr perf test -w inlineloop ... $ perf script --fields +srcline ... perf-inlineloop 467586 4649.344493: 950905 cpu_core/cycles/P: 55dfda2829c0 parent+0x0 (perf) inlineloop.c:31 55dfda282a96 inlineloop+0x86 (perf) inlineloop.c:47 55dfda236420 run_workload+0x59 (perf) builtin-test.c:715 55dfda236b03 cmd_test+0x413 (perf) builtin-test.c:825 ... ``` After this change: ``` $ perf record --call-graph lbr perf test -w inlineloop ... $ perf script --fields +srcline ... perf-inlineloop 529703 11878.680815: 950905 cpu_core/cycles/P: 555ce86be9e6 leaf+0x26 inlineloop.c:20 (inlined) 555ce86be9e6 middle+0x26 inlineloop.c:27 (inlined) 555ce86be9e6 parent+0x26 (perf) inlineloop.c:32 555ce86bea96 inlineloop+0x86 (perf) inlineloop.c:47 555ce8672420 run_workload+0x59 (perf) builtin-test.c:715 555ce8672b03 cmd_test+0x413 (perf) builtin-test.c:825 ... ``` Reviewed-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Ian Rogers <irogers@google.com> Acked-by: Dapeng Mi <dapeng1.mi@linux.intel.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Dmitriy Vyukov <dvyukov@google.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: James Clark <james.clark@linaro.org> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Krzysztof Łopatowski <krzysztof.m.lopatowski@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Weilin Wang <weilin.wang@intel.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2026-02-06perf regs: Remove __weak attributive arch_sdt_arg_parse_op() functionDapeng Mi12-473/+441
In line with the previous patch, the __weak arch_sdt_arg_parse_op() function is removed. Architectural-specific implementations in the arch/ directory are now converted into sub-functions within the util/perf-regs-arch/ directory. The perf_sdt_arg_parse_op() function will call these sub-functions based on the EM_HOST. This change enables cross-architecture calls to arch_sdt_arg_parse_op(). No functional changes are intended.

2026-02-06perf regs: Remove __weak attributive arch__xxx_reg_mask() functionsDapeng Mi30-236/+332
Currently, some architecture-specific perf-regs functions, such as arch__intr_reg_mask() and arch__user_reg_mask(), are defined with the __weak attribute. This approach ensures that only functions matching the architecture of the build/run host are compiled and executed, reducing build time and binary size. However, this __weak attribute restricts these functions to be called only on the same architecture, preventing cross-architecture functionality. For example, a perf.data file captured on x86 cannot be parsed on an ARM platform. To address this limitation, this patch removes the __weak attribute from these perf-regs functions. The architecture-specific code is moved from the arch/ directory to the util/perf-regs-arch/ directory. The appropriate architectural functions are then called based on the EM_HOST. No functional changes are intended.

2026-02-06perf arch: Update arch headers to use relative UAPI pathsDapeng Mi9-9/+9
The architectural specific headers perf_regs.h currently rely on the host architecture's 'asm/perf_regs.h'. This can lead to compilation inconsistencies or failures when including and building perf for a target architecture that differs from the host's architecture. Explicitly point to the UAPI headers within the tools source tree using relative paths. This ensures that perf is always built against the intended architecture. No functional changes are intended.

2026-02-06perf regs: Fix abort for "-I" or "--user-regs" optionsDapeng Mi1-7/+6
Fix an issue where the `perf` tool aborts unexpectedly when running the following command: ``` perf record -e cycles -I -- true Usage: perf record [<options>] [<command>] or: perf record [<options>] -- <command> [<options>] -I, --intr-regs[=<any register>] sample selected machine registers on interrupt, use '-I?' to list register names ``` The usage of the `-I` or `--user-regs` options without specifying any registers should default to sampling all general-purpose registers. However, this currently causes an abnormal termination. The issue was introduced by commit 3d06db9bad1a ("perf regs: Refactor use of arch__sample_reg_masks() to perf_reg_name()"). This patch resolves the problem, ensuring that the `-I` or `--user-regs` options work as intended without causing an abort.

2026-02-04perf kvm stat: Remove use of the arch directoryIan Rogers28-177/+451
`perf kvm stat` supports record and report options. By using the arch directory a report for a different machine type cannot be supported. Move the kvm-stat code out of the arch directory and into util/kvm-stat-arch following the pattern of perf-regs and dwarf-regs. Avoid duplicate symbols by renaming functions to have the architecture name within them. For global variables, wrap them in an architecture specific function. Selecting the architecture to use with `perf kvm stat` is selected by EM_HOST, ie no different than before the change. Later the ELF machine can be determined from the session or a header feature (ie EM_HOST at the time of the record). The build and #define HAVE_KVM_STAT_SUPPORT is now redundant so remove across Makefiles and in the build. Opportunistically constify architectural structs and arrays.

2026-02-04libperf build: Always place libperf includes firstIan Rogers1-1/+1
When building tools/perf the CFLAGS can contain a directory for the installed headers. As the headers may be being installed while building libperf.a this can cause headers to be partially installed and found in the include path while building an object file for libperf.a. The installed header may reference other installed headers that are missing given the partial nature of the install and then the build fails with a missing header file. Avoid this by ensuring the libperf source headers are always first in the CFLAGS.

2026-02-03perf capstone: Support for dlopen-ing libcapstone.soIan Rogers5-42/+179
If perf is built with LIBCAPSTONE_DLOPEN=1, support dlopen-ing libcapstone.so and then calling the necessary functions by looking them up using dlsym. The types come from capstone.h which means the libcapstone feature check needs to pass, and NO_CAPSTONE=1 hasn't been defined. This will cause the definition of HAVE_LIBCAPSTONE_SUPPORT. Earlier versions of this code tried to declare the necessary capstone.h constants and structs, but they weren't stable and caused breakages across libcapstone releases.

2026-01-28perf jevents: Add br metric group for branch statistics on IntelIan Rogers1-0/+138
The br metric group for branches itself comprises metric groups for total, taken, conditional, fused and far metric groups using JSON events. Conditional taken and not taken metrics are specific to Icelake and later generations, so the presence of the event is used to determine whether the metric should exist.
