Hi all, This patch adds support for ftrace operations on the ARM architecture. This support is needed by kgraft and possibly other ftrace-based tools. My goal is to have kgraft working on ARM and aarch64.
I tested this patch with a toy implementation of kgraft for ARM and basic usage of function and function_graph tracers It doesn't show any problem with the ftrace selftests and the tests found today in branch ftrace/testing-mystuff of linux-trace repository (git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git) Jean-Jacques Hiblot (1): arm: ftrace: Adds support for ftrace operations arch/arm/Kconfig | 2 ++ arch/arm/include/asm/ftrace.h | 3 ++ arch/arm/kernel/entry-common.S | 68 +++++++++++++++++++++++++++++++++++++++++- arch/arm/kernel/ftrace.c | 34 +++++++++++++++++++++ 4 files changed, 106 insertions(+), 1 deletion(-) -- 2.1.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
