4a73aff8 - perf tools: Create generic syscall table support

Thu, 09 Jan 2025 02:36:16 +0000

perf tools: Create generic syscall table supportCurrently each architecture in perf independently generates syscallheaders.Adapt the work that has gone into unifying syscall headerimplementations in the kernel to work with perf tools.Introduce this framework with riscv at first. riscv previously relied onlibaudit, but with this change, perf tools for riscv no longer needsthis external dependency.Signed-off-by: Charlie Jenkins Cc: Adrian Hunter Cc: Alexander Shishkin Cc: Arnd Bergmann Cc: Christian Brauner Cc: Guo Ren Cc: Günther Noack Cc: Ian Rogers Cc: Ingo Molnar Cc: James Clark Cc: Jiri Olsa Cc: John Garry Cc: Jonathan Corbet Cc: Leo Yan Cc: Mark Rutland Cc: Mickaël Salaün Cc: Mike Leach Cc: Namhyung Kim Cc: Palmer Dabbelt Cc: Paul Walmsley Cc: Peter Zijlstra Cc: Will Deacon Link: https://lore.kernel.org/r/20250108-perf_syscalltbl-v6-1-7543b5293098@rivosinc.comSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/arch/riscv/Makefile

ddbfb6f2 - perf build: Remove PERF_HAVE_DWARF_REGS

Fri, 08 Nov 2024 23:46:05 +0000

perf build: Remove PERF_HAVE_DWARF_REGSPERF_HAVE_DWARF_REGS was true when an architecture had a dwarf-regs.cfile. There are no more architecture dwarf-regs.c files, selection isdone using constants from the ELF file rather than conditionalcompilation. When removing PERF_HAVE_DWARF_REGS was the only variablein the Makefile, remove the Makefile.Add missing SPDX for RISC-V Makefile.Reviewed-by: Masami Hiramatsu (Google) Signed-off-by: Ian Rogers Cc: Anup Patel Cc: Yang Jihong Cc: Palmer Dabbelt Cc: David S.

perf dwarf-regs: Remove PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSETPERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET was used for BPF prologuesupport which was removed in Commit 3d6dfae88917 ("perf parse-events:Remove BPF event support"). The code is no longer used so remove.Remove the offset from various dwarf-regs.c tables and the dependenceon ptrace.h.
