At least nothing you'd rely onto. There is something like that, but it doesn't work very well yet. If you browse my website, in the patches directory: http://www.user-mode-linux.org/~blaisorblade/patches/devel-guest/ there are some test trees which include TLS support code. It depends - at this stage, because of the difference between distros (glib= c=20 version mainly), with the same code I can see one behaviour (say "nothing=20 works") and somebody else have no problem. My Debian Sarge appears to be very picky, while Jeff, with more or less the= =20 same patches, has FC4 working "well enough" (there are still some spurious = segfaults, however). And S=E9bastien Dugu=E9 tried LinuxFromScratch 6.1 with glibc 2.3.5 and it = worked=20 well - but I think LFS is not a heavy stress tool for NPTL. > I am currently using a 2.6.12 guest kernel with RH9 rootfs and have > moved things around in /lib so as to avoid problems with NPTL but > I was hoping that there might be some improvements which would allow > me to use later versions of glibc without modification. RH9 is entirely different - that wouldn't even work with a plain 2.6 kernel= on=20 i386, I think. In fact, I've seen some early NPTL code on Ingo Molnar's site and it isn't = at=20 all compatible with current API. So RH9's NPTL will never be supported. > Is this possible? > cgf --=20 Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
