From 008e901b70282183b52ee80d838d2994b2610231 Mon Sep 17 00:00:00 2001 From: David Abdurachmanov <david.abdurachmanov@gmail.com> Date: Mon, 10 Dec 2018 21:43:55 +0100 Subject: riscv: define CREATE_TRACE_POINTS in ptrace.c Define CREATE_TRACE_POINTS in order to create functions and structures for the trace events. This is needed if HAVE_SYSCALL_TRACEPOINTS and CONFIG_FTRACE_SYSCALLS are enabled, otherwise we get linking errors: [..] MODPOST vmlinux.o kernel/trace/trace_syscalls.o: In function `.L0 ': trace_syscalls.c:(.text+0x1152): undefined reference to `__tracepoint_sys_enter' trace_syscalls.c:(.text+0x126c): undefined reference to `__tracepoint_sys_enter' trace_syscalls.c:(.text+0x1328): undefined reference to `__tracepoint_sys_enter' trace_syscalls.c:(.text+0x14aa): undefined reference to `__tracepoint_sys_enter' trace_syscalls.c:(.text+0x1684): undefined reference to `__tracepoint_sys_exit' trace_syscalls.c:(.text+0x17a0): undefined reference to `__tracepoint_sys_exit' trace_syscalls.c:(.text+0x185c): undefined reference to `__tracepoint_sys_exit' trace_syscalls.c:(.text+0x19de): undefined reference to `__tracepoint_sys_exit' arch/riscv/kernel/ptrace.o: In function `.L0 ': ptrace.c:(.text+0x4dc): undefined reference to `__tracepoint_sys_enter' ptrace.c:(.text+0x632): undefined reference to `__tracepoint_sys_exit' make: *** [Makefile:1036: vmlinux] Error 1 Signed-off-by: David Abdurachmanov <david.abdurachmanov@gmail.com> Fixes: b78002b395b4 ("riscv: add HAVE_SYSCALL_TRACEPOINTS to Kconfig") Signed-off-by: Palmer Dabbelt <palmer@sifive.com> --- arch/riscv/kernel/ptrace.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'arch/riscv') diff --git a/arch/riscv/kernel/ptrace.c b/arch/riscv/kernel/ptrace.c index c1b51539c3e2..a34c98b49dcb 100644 --- a/arch/riscv/kernel/ptrace.c +++ b/arch/riscv/kernel/ptrace.c @@ -25,6 +25,8 @@ #include <linux/sched.h> #include <linux/sched/task_stack.h> #include <linux/tracehook.h> + +#define CREATE_TRACE_POINTS #include <trace/events/syscalls.h> enum riscv_regset { -- cgit v1.2.3
