tools headers: Sync syscall table with kernel sources

2025-12-24T19:43:36+00:00

To pick up changes from: b36d4b6aa88ef039 ("arch: hookup listns() system call") This should be used to beautify the syscall arguments and it addresses these tools/perf build warnings: Warning: Kernel ABI header differences: diff -u tools/include/uapi/asm-generic/unistd.h include/uapi/asm-generic/unistd.h diff -u tools/scripts/syscall.tbl scripts/syscall.tbl diff -u tools/perf/arch/x86/entry/syscalls/syscall_32.tbl arch/x86/entry/syscalls/syscall_32.tbl diff -u tools/perf/arch/x86/entry/syscalls/syscall_64.tbl arch/x86/entry/syscalls/syscall_64.tbl diff -u tools/perf/arch/powerpc/entry/syscalls/syscall.tbl arch/powerpc/kernel/syscalls/syscall.tbl diff -u tools/perf/arch/s390/entry/syscalls/syscall.tbl arch/s390/kernel/syscalls/syscall.tbl diff -u tools/perf/arch/mips/entry/syscalls/syscall_n64.tbl arch/mips/kernel/syscalls/syscall_n64.tbl diff -u tools/perf/arch/arm/entry/syscalls/syscall.tbl arch/arm/tools/syscall.tbl diff -u tools/perf/arch/sh/entry/syscalls/syscall.tbl arch/sh/kernel/syscalls/syscall.tbl diff -u tools/perf/arch/sparc/entry/syscalls/syscall.tbl arch/sparc/kernel/syscalls/syscall.tbl diff -u tools/perf/arch/xtensa/entry/syscalls/syscall.tbl arch/xtensa/kernel/syscalls/syscall.tbl Please see tools/include/uapi/README. Note that s390 syscall table is still out of sync as it switches to use the generic table. But I'd like to minimize the change in this commit.

perf auxtrace: Remove errno.h from auxtrace.h and fix transitive dependencies

2025-11-14T07:03:11+00:00

errno.h isn't used in auxtrace.h so remove it and fix build failures caused by transitive dependencies through auxtrace.h on errno.h. Signed-off-by: Ian Rogers Reviewed-by: James Clark Signed-off-by: Namhyung Kim

perf build: Remove NO_AUXTRACE build option

2025-11-14T07:03:11+00:00

The NO_AUXTRACE build option was used when the __get_cpuid feature test failed or if it was provided on the command line. The option no longer avoids a dependency on a library and so having the option is just adding complexity to the code base. Remove the option CONFIG_AUXTRACE from Build files and HAVE_AUXTRACE_SUPPORT by assuming it is always defined. Signed-off-by: Ian Rogers Reviewed-by: James Clark Signed-off-by: Namhyung Kim

perf powerpc: Add basic CONFIG_AUXTRACE support for VPA pmu on powerpc

2025-10-01T14:22:04+00:00

The powerpc PMU collecting Dispatch Trace Log (DTL) entries makes use of AUX support in perf infrastructure. The PMU driver has the functionality to collect trace entries in the aux buffer. On the tools side, this data is made available as PERF_RECORD_AUXTRACE records. This record is generated by "perf record" command. To enable the creation of PERF_RECORD_AUXTRACE, add functions to initialize auxtrace records ie "auxtrace_record__init()". Fill in fields for other callbacks like info_priv_size, info_fill, free, recording options etc. Define auxtrace_type as PERF_AUXTRACE_VPA_DTL. Add header file to define vpa dtl pmu specific details.

perf sort: Use perf_env to set arch sort keys and header

2025-07-25T17:37:58+00:00

Previously arch_support_sort_key and arch_perf_header_entry used a weak symbol to compile as appropriate for x86 and powerpc. A limitation to this is that the handling of a data file could vary in cross-platform development. Change to using the perf_env of the current session to determine the architecture kind and set the sort key and header entries as appropriate.

perf sample: Remove arch notion of sample parsing

2025-07-25T17:37:58+00:00

By definition arch sample parsing and synthesis will inhibit certain kinds of cross-platform record then analysis (report, script, etc.). Remove arch_perf_parse_sample_weight and arch_perf_synthesize_sample_weight replacing with a common implementation. Combine perf_sample p_stage_cyc and retire_lat as weight3 to capture the differing uses regardless of compiled for architecture.

Now a single beauty file is generated and used by all architectures, remove the per-architecture Makefiles, Kbuild files and previous generator script. Note: there was conversation with Charlie Jenkins and they'd written an alternate approach to support multiple architectures: https://lore.kernel.org/all/20250114-perf_syscall_arch_runtime-v1-1-5b304e408e11@rivosinc.com/ It would have been better to have helped Charlie fix their series (my apologies) but they agreed that the approach taken here was likely best for longer term maintainability: https://lore.kernel.org/lkml/Z6Jk_UN9i69QGqUj@ghost/ Signed-off-by: Ian Rogers Reviewed-by: Howard Chu Reviewed-by: Charlie Jenkins Reviewed-by: Namhyung Kim Acked-by: Arnaldo Carvalho de Melo Link: https://lore.kernel.org/r/20250319050741.269828-11-irogers@google.com Signed-off-by: Namhyung Kim
