Subject: [PATCH 0/3] A kernel tracing interface
Date: Mon, 12 Nov 2007 17:02:10 -0800 [thread overview]
Message-ID: <1194915731.913.16.camel@lc4eb748232119.ibm.com> (raw)
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
