From e76f76a37d046957f46814d9a106f0f5b4f8af72 Mon Sep 17 00:00:00 2001 From: Bruce Ashfield Date: Fri, 20 Aug 2010 12:24:43 -0400 Subject: ftrace: add trace-cmd for ftrace control and config Rather than manually configuring ftrace, trace-cmd was created to provide a more user friendly interface to the tracer. Some examples are: # ./trace-cmd record -e all ls /bin Then to see the information: # ./trace-cmd report To see just a subsystem: # ./trace-cmd record -e irq ls /bin To list the available trace events: # ./trace-cmd list -e You can also trace a single trace point with one of two methods: # ./trace-cmd record -e sched:sched_wakeup ls /bin Or simply: # ./trace-cmd record -e sched_wakeup ls /bin This tool also works with tracers (plugins) as well as events # ./trace-cmd list -p Signed-off-by: Bruce Ashfield --- meta/packages/trace-cmd/trace-cmd_git.bb | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 meta/packages/trace-cmd/trace-cmd_git.bb (limited to 'meta/packages') diff --git a/meta/packages/trace-cmd/trace-cmd_git.bb b/meta/packages/trace-cmd/trace-cmd_git.bb new file mode 100644 index 0000000000..57d54d6683 --- /dev/null +++ b/meta/packages/trace-cmd/trace-cmd_git.bb @@ -0,0 +1,21 @@ +DESCRIPTION = "User interface to Ftrace" +LICENSE = "GPL" +LIC_FILES_CHKSUM = "file://COPYING;md5=751419260aa954499f7abaabaa882bbe" + +DEPENDS = "glibc" + +PR = r0 +PV = "1.0.4+git${SRCPV}" + +SRC_URI = "git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git;protocol=git" +S = "${WORKDIR}/git" + + +do_compile() { + oe_runmake ARCH="${ARCH}" CC="${CC}" LD="${LD}" prefix=${prefix} +} + +do_install() { + oe_runmake ARCH="${ARCH}" CC="${CC}" LD="${LD}" \ + prefix=${prefix} DESTDIR=${D} install +} -- cgit v1.2.3-54-g00ecf
