From d6e1cc6b7220073d6d5d2edd79edf2d36da046bf Mon Sep 17 00:00:00 2001 From: Tiezhu Yang Date: Tue, 30 May 2023 18:09:59 +0800 Subject: perf arm64: Handle __NR3264_ prefixed syscall number After commit 9854e7ad35fe ("perf arm64: Simplify mksyscalltbl"), in the generated syscall table file syscalls.c, there exist some __NR3264_ prefixed syscall numbers such as [__NR3264_ftruncate], it looks like not so good, just do some small filter operations to handle __NR3264_ prefixed syscall number as a digital number. Without this patch: [__NR3264_ftruncate] = "ftruncate", With this patch: [46] = "ftruncate", Suggested-by: Alexander Kapshuk Reviewed-by: Huacai Chen Reviewed-by: Leo Yan Signed-off-by: Tiezhu Yang Acked-by: Ian Rogers Cc: Ingo Molnar Cc: Peter Zijlstra Cc: loongarch@lists.linux.dev Link: https://lore.kernel.org/r/1685441401-8709-4-git-send-email-yangtiezhu@loongson.cn Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/arch/arm64/entry/syscalls/mksyscalltbl | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/tools/perf/arch/arm64/entry/syscalls/mksyscalltbl b/tools/perf/arch/arm64/entry/syscalls/mksyscalltbl index 84976dc5bdcf..0bcd64a74642 100755 --- a/tools/perf/arch/arm64/entry/syscalls/mksyscalltbl +++ b/tools/perf/arch/arm64/entry/syscalls/mksyscalltbl @@ -40,6 +40,7 @@ create_table() } $gcc -E -dM -x c -I $incpath/include/uapi $input \ - |sed -ne 's/^#define __NR_//p' \ - |sort -t' ' -k2 -n \ + |awk '$2 ~ "__NR" && $3 !~ "__NR3264_" { + sub("^#define __NR(3264)?_", ""); + print | "sort -k2 -n"}' \ |create_table -- cgit v1.2.3
