Hi Paul, I figured out I needed some userspace RCU for the userspace tracing part of LTTng (for quick read access to the control variables) to trace userspace pthread applications. So I've done a quick-and-dirty userspace RCU implementation. It works so far, but I have not gone through any formal verification phase. It seems to work on paper, and the tests are also OK (so far), but I offer no guarantee for this 300-lines-ish 1-day hack. :-) If you want to comment on it, it would be welcome. It's a userland-only library. It's also currently x86-only, but only a few basic definitions must be adapted in urcu.h to port it. Here is the link to my git tree : git://lttng.org/userspace-rcu.git http://lttng.org/cgi-bin/gitweb.cgi?p=userspace-rcu.git;a=summary Thanks, Mathieu -- Mathieu Desnoyers OpenPGP key fingerprint: 8CD5 52C3 8E3C 4140 715F BA06 3F25 A8FE 3BAE 9A68 | ||||||||||
