Date: Mon, 12 Nov 2007 17:02:10 -0800 From: "David J. Wilder" <dwilder@...ibm.com> To: linux-kernel@...r.kernel.org Cc: systemtap@...rces.redhat.com Subject: [PATCH 0/3] A kernel tracing interface These patches provide a kernel tracing interface called "trace". ChangeLog: -Added a new example that demonstrates per-cpu continuous tracing of data generated by 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 against 2.6.23-mm1 Summary of patches: [patch 1/3] Relay Reset Consumed [patch 2/3] Trace code and documentation [patch 3/3] Trace samples Note: Patch 1/3 provides a service used by patch 2/3 thus must be applied first or at the same time. Note: The sem_watch example requires that /lib/semaphore-sleepers.c is patched to add several markers around the semaphore primitives, see the patch at: http://lkml.org/lkml/2007/11/12/279 Signed-off-by: David Wilder <dwilder@...ibm.com> - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
