lttng can trace quite a few events. Interrupts, system calls, etc. Might be worth a look, and it's quite well maintained against various kernel versions.
It's pretty heavyweight, but you could use filters to cut down on the events traced. By default output goes to the file system, which could be on pramfs. (Or NFS - I'm sorry I lost track of the original request - don't know if this is an option or not.) I'm not sure, however, that the buffers are pushed to user-space, through the daemon, and back to the file system in an expedient manner. I agree it might be worth a look for this use case. We use it at Sony quite a bit and it's valuable. -- Tim ============================= Tim Bird Architecture Group Chair, CE Linux Forum Senior Staff Engineer, Sony Corporation of America ============================= -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
