From 3b573bf318d894b4290e194c4d7dbcba8c1f6ead Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 14 Feb 2020 16:21:40 -0300 Subject: perf bpf: Remove bpf/ subdir from bpf.h headers used to build bpf events The bpf.h file needed gets installed in /usr/lib/include/perf/bpf/bpf.h, and /usr/lib/include/perf/ is added to the include path passed to clang to build the eBPF bytecode, so just remove "bpf/", its directly in the path passed already. This was working by accident, fix it. I.e. now this is back working: # cat /home/acme/git/perf/tools/perf/examples/bpf/hello.c #include int syscall_enter(openat)(void *args) { puts("Hello, world\n"); return 0; } license(GPL); # perf trace -e /home/acme/git/perf/tools/perf/examples/bpf/hello.c 0.000 pickup/21493 __bpf_stdout__(Hello, world) 56.462 sh/13539 __bpf_stdout__(Hello, world) 56.536 sh/13539 __bpf_stdout__(Hello, world) 56.673 sh/13539 __bpf_stdout__(Hello, world) 56.781 sh/13539 __bpf_stdout__(Hello, world) 56.707 perf/13182 __bpf_stdout__(Hello, world) 56.849 perf/13182 __bpf_stdout__(Hello, world) ^C # Cc: Adrian Hunter Cc: Jiri Olsa Cc: Namhyung Kim Link: https://lkml.kernel.org/n/tip-d9myswhgo8gfi3vmehdqpxa7@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/include/bpf/unistd.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'tools/perf/include/bpf/unistd.h') diff --git a/tools/perf/include/bpf/unistd.h b/tools/perf/include/bpf/unistd.h index d1a35b6c649d..ca7877f9a976 100644 --- a/tools/perf/include/bpf/unistd.h +++ b/tools/perf/include/bpf/unistd.h @@ -1,6 +1,6 @@ // SPDX-License-Identifier: LGPL-2.1 -#include +#include static int (*bpf_get_current_pid_tgid)(void) = (void *)BPF_FUNC_get_current_pid_tgid; -- cgit
