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) change since v1: - changed the title and the commit log of the patch to make it more understandable Jean-Jacques Hiblot (1): arm: ftrace: Adds support for CONFIG_DYNAMIC_FTRACE_WITH_REGS 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 From mboxrd@z Thu Jan 1 00:00:00 1970 From: jjhiblot@traphandler.com (Jean-Jacques Hiblot) Date: Mon, 10 Nov 2014 09:56:16 +0100 Subject: [PATCH v2 00/01] arm: ftrace: Adds support for CONFIG_DYNAMIC_FTRACE_WITH_REGS In-Reply-To: <20141107115225.72bc6cbf@gandalf.local.home> References: <20141107115225.72bc6cbf@gandalf.local.home> Message-ID: <1415609777-18525-1-git-send-email-jjhiblot@traphandler.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This patch adds support for ftrace operations on the ARM architecture.
