Wilder" To: linux-kernel@vger.kernel.org, akpm@linux-foundation.org Cc: systemtap@sourceware.org Content-Type: text/plain Date: Mon, 03 Mar 2008 15:51:39 -0800 Message-Id: <1204588300.32186.6.camel@lc4eb748232119.ibm.com> Mime-Version: 1.0 X-Mailer: Evolution 2.0.2 (2.0.2-35.0.4.el4) Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1357 Lines: 39 These patches provide a kernel tracing interface called "trace". ChangeLog: -Added "Examples of user interface" to doc. -Fix state write to match only on exact commands. -Updated to 2.6.25-rc2-mm1 -Added a new example that demonstrates per-cpu continuous tracing of data generated using marker probes. -Removed inline from relay patch. -Moved examples into /sample directory. The motivation for "trace" is to: - Provide a simple set of tracing primitives that will utilize the high- performance and low-overhead of relayfs for passing traces data from kernel to user space. - Provide a common user interface for managing kernel traces. - Allow for binary as well as ascii trace data. - Incorporate features from the systemtap runtime that are useful to others. Patches are built against 2.6.25-rc2-mm1. Tested on: 2.6.25-rc3 Summary of patches: [patch 1/3] Relay Reset Consumed [patch 2/3] Trace code and documentation [patch 3/3] Trace sample Note: Patch 1/3 provides a service used by patch 2/3 thus must be applied first or at the same time.
