perf util: Make util its own libraryMake the util directory into its own library. This is done to avoidcompiling code twice, once for the perf tool and once for the perfpython module. For convenience: arch/common.c scripts/perl/Perf-Trace-Util/Context.c scripts/python/Perf-Trace-Util/Context.care made part of this library.Signed-off-by: Ian Rogers Reviewed-by: James Clark Cc: Suzuki K Poulose Cc: Kees Cook Cc: Palmer Dabbelt Cc: Albert Ou Cc: Nick Terrell Cc: Gary Guo Cc: Alex Gaynor Cc: Boqun Feng Cc: Wedson Almeida Filho Cc: Ze Gao Cc: Alice Ryhl Cc: Andrei Vagin Cc: Yicong Yang Cc: Jonathan Cameron Cc: Guo Ren Cc: Miguel Ojeda Cc: Will Deacon Cc: Mike Leach Cc: Leo Yan Cc: Oliver Upton Cc: John Garry Cc: Benno Lossin Cc: Björn Roy Baron Cc: Andreas Hindborg Cc: Paul Walmsley Signed-off-by: Namhyung Kim Link: https://lore.kernel.org/r/20240625214117.953777-7-irogers@google.com List of files: /linux-6.15/tools/perf/util/perf-regs-arch/Build

5000e7f6 - perf parse-regs: Refactor arch register parsing functions

Tue, 06 Jun 2023 01:45:54 +0000

perf parse-regs: Refactor arch register parsing functionsEvery architecture has a specific register parsing function forreturning register name based on register index, to support crossanalysis (e.g. we use perf x86 binary to parse Arm64's perf data), webuild all these register parsing functions into the tool, this is whywe place all related functions into util/perf_regs.c.Unfortunately, since util/perf_regs.c needs to include every arch'sperf_regs.h, this easily introduces duplicated definitions coming frommultiple headers, finally it's fragile for building and difficult formaintenance.We cannot simply move these register parsing functions into thecorresponding 'arch' folder, the folder is only conditionally builtbased on the target architecture.Therefore, this commit creates a new folder util/perf-regs-arch/ anduses a dedicated source file to keep every architecture's registerparsing function to avoid definition conflicts.This is only a refactoring, no functionality change is expected.Committer notes:Had to add util/perf-regs-arch/*.c to tools/perf/util/python-ext-sourcesto keep 'perf test python' passing.Signed-off-by: Leo Yan Acked-by: Ian Rogers Cc: Adrian Hunter Cc: Albert Ou Cc: Alexander Shishkin Cc: Eric Lin Cc: Fangrui Song Cc: Guo Ren Cc: Huacai Chen Cc: Ingo Molnar Cc: Ivan Babrou Cc: James Clark Cc: Jiri Olsa Cc: John Garry Cc: Kan Liang Cc: Mark Rutland Cc: Mike Leach Cc: Ming Wang Cc: Namhyung Kim Cc: Palmer Dabbelt Cc: Paul Walmsley Cc: Peter Zijlstra Cc: Sandipan Das Cc: Will Deacon Cc: linux-arm-kernel@lists.infradead.orgCc: linux-csky@vger.kernel.orgCc: linux-riscv@lists.infradead.orgLink: https://lore.kernel.org/r/20230606014559.21783-2-leo.yan@linaro.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/util/perf-regs-arch/Build
