What I meant was more like "It is not trivial to fix and nobody is motivated enough to fix it yet. Sorry, ignore it for now." I thought "KQEMU/FreeBSD is borken" was too harsh. ;-) > > Even if we make it work with FreeBSD, I would expect similar > > results. > > Is that because 2.6 is already better? Dunno. I am not a Linux hacker. ;-) > Is it a 2.6 host or target? Target. BTW, there are many OSs out there that they allow FP operations in kernel including Windows, Mac OS X, DragonFlyBSD, etc. Even ndis(4) causes lots of fpudna warnings with some Windows drivers. Since there is no driver for it, I am stuck with ndis(4). Same thing is true for QEMU, i.e., I have no alternative. Bochs does not support FreeBSD/amd64 guest (no PAT emulation), VMware does not support FreeBSD host, Xen is far from dom0 support, etc. If someone's motivated enough, we can borrow some code from DragonFlyBSD: http://lists.freebsd.org/pipermail/freebsd-arch/2004-June/002271.html Jung-uk Kim
