After speaking with Mathieu at the Linux Collaboration Summit, I worked up these patches. Thanks Mathieu, for helping me with this. They should be fairly straight forward, the first one enables syscall entry tracing, the second gives us system call names in lttv, and the third fixes up the trace clock to work better on Octeon CPUs. The base of the patch set is the patch-2.6.32.9-lttng-0.198.tar.gz bundle from the download page on the web site. The patches are really only tested on a 64-bit kernel running on a 12 CPU Octeon SOC. I think the 32-bit code will compile and is correct, but I have not tested it.
