Hi, ATM it doesn't look like we can enable 2.6.16 by default in 7.0. The reasons= : - java showstopper (epoll not implemented) - futex/TLS for amd64 not in -current for testing - futexes not completely right - *at() not implemented - the time to test a 2.6.16 default until 7.0 shrinks fast Roman has some preliminary work regarding *at() and it looks good to =20 him. He wants me to test some stuff but I don't have enough time in =20 the next weeks because of work related stuff. Any volunteers to help =20 out? In p4 we have the futex/TLS stuff for amd64 but because of the futexes =20 not completely right part it is not committed to current yet. As we =20 already have the futex and TLS stuff for i386 on a similar level in =20 current, I would say we should go ahead and sync the amd64 stuff. It =20 is not used by default, so we don't break existing linux stuff and we =20 get the benefit of more people being able to have a look at it and =20 play with it. So what are your opinions, shall we give jkim@ the green =20 light to MFp4 the futex/TLS stuff? Regarding the futexes not being completely right and the epoll stuff: =20 I think it needs to be done now, not in a month or two, else we don't =20 have enough time to let people play with this before the release of =20 7.0. Anyone with a little bit of time at hand out there? We need a =20 specification what the futexes are supposed to do (so far we didn't =20 find a good description, and the linux code is hard to read and =20 doesn't not really tell what it is _supposed_ to do) and we need =20 people which compare the current code we have with this specification. =20 Finding a regression test for futexes would also be nice. Bye, Alexander. --=20 TODAY: =09A nice place to visit, but you can't stay here for long. http://www.Leidinger.net Alexander @ Leidinger.net: PGP ID =3D B0063FE7 http://www.FreeBSD.org netchild @ FreeBSD.org : PGP ID =3D 72077137
