So, $(SRCARCH) maps to both powerpc and powerpc64m which will set NO_SYSCALL_TABLE to zero, thus linking against tools/perf/util/syscalltbl.o, which will include the generated syscalls_64.c only for ppc64, b00m. +++ b/tools/perf/Makefile.config @@ -27,6 +27,8 @@ NO_SYSCALL_TABLE := 1 # Additional ARCH settings for ppc ifeq ($(SRCARCH),powerpc) NO_PERF_REGS := 0 + NO_SYSCALL_TABLE := 0 + CFLAGS += -I$(OUTPUT)arch/powerpc/include/generated LIBUNWIND_LIBS := -lunwind -lunwind-ppc64 endif +++ b/tools/perf/util/syscalltbl.c static const char **syscalltbl_native = syscalltbl_s390_64; +#elif defined(__powerpc64__) +#include <asm/syscalls_64.c> +const int syscalltbl_native_max_id = SYSCALLTBL_POWERPC_64_MAX_ID; +static const char **syscalltbl_native = syscalltbl_powerpc_64; #endif
