- Back from Linuxcon where I gave the talk "Tracing in the Real World".
- lttngtop is now public http://git.dorsal.polymtl.ca/?p=lttngtop.git;a=summary (not yet announced on ltt-dev but during the conference)
- in a separate private branch lttngtop is parsing traces in live mode : reads the buffer directly from memory, only the metadata file is spliced to disk, at each refresh it only does a few ioctl syscalls, seems more efficient than "top", need benchmark now
- Next steps : merge all custom code in babeltrace to make it support hooks, seek and mmap read (all needed for lttngtop live and offline)
