I think we are pretty close. Some locking problems appear when the ksetest program is run a large (100+ or so) times, those should probably be fixed first. > You and jhb said that the thread allocator could be rewritten using the new > uma mechanisms. if that is done, then we could check in what we have > minus some changes that are dependent on comments from others.. That is done, and checked in. There are a few problems with it still. > (I think DES would like to have a go at the ptrace changes) Sure. Also, gdb doesn't work too well on threaded apps, but I think that is expected at this point. > Is the system stable with only non KSE processes? I haven't noticed any problems with non-KSE processes, however I haven't done any real testing. > If we could generate good diffs it would help > others to look and comment. Yeah. Other than the cleanups I've mentioned above (some locking, and the uma stuff needs a second pass), my next goal is to get clean diffs so that we can start the review process. -- Jonathan Mini <mini@freebsd.org> http://www.haikugeek.com "He who is not aware of his ignorance will be only misled by his knowledge." -- Richard Whatley To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe p4-projects" in the body of the message
