Far be it for me to stop you from adventuring into the FreeBSD world, I encourage you actually. :-) However, note that you always had and will have the freedom of choice. One Linux distribution might have chosen to go the pulseaudio way (binary-only ones usually do), but FreeBSD inspired ones, with ports-like features, offer you the choice to go plain ALSA or even OSS (Crux, Gentoo etc.). In what concerns nouveau, I'm afraid there's no running away from it. Reverse engineering close source drivers for modern GPU-s is an incredibly hard task. FreeBSD will likely get nouveau when KMS gets finished (soon I hear?). Until then, the good old nVidia blob will do. So instead of seeing FreeBSD as a place of retreat, see it as an adventure! :-) My question is: Should I try the amd64 version of FreeBSD with my Intel Core i7-2600 processor or should I use the i386?

However, Freshports still has a less-than-favorable status for this port: http://www.freshports.org/www/chromium/ Now... that being said, I have a co-worker that is running Chromium every day on FreeBSD-8.1 and he's very happy with it. Though, given the above consideration, both him and I have decided to _not_ deploy this browser in production (at least until we can get some love on those vulnerabilities). So, I guess I'd like to throw the query out there... If you had to pick between Firefox and Chrome for distribution to 1000 FreeBSD systems running 8.1 in production... which would you choose? We're heavily leaning toward Firefox, but would love to hear other's opinions of Chrome (if it requires Linux emulation, that may be a death-knell, leaving Firefox the only real choice???). I've been an avid Firefox user until ~1 month ago. I just couldn't put up with the sluggishness anymore. Tried to use Firefox 4 beta. No dice. The JS engine _is_ faster but that didn't solve the problem. The UI is just not OK. I used to think it was because of the multi-threaded design, until Opera rolled out version 10 which is just as snappy as Google Chrome. The only downside with Opera is that it's just too strict wrt standards. FF and Chrome use all kinds of quirks to make old websites render reasonably well. Still, given the current situation on FreeBSD, I'd go with Opera. I love Mozilla and its push towards a free/open web, but with version 4 they seem to have lost focus on what it matters for the majority of the people. Sure, fast web page rendering is important, but I for one wouldn't mind a slow[ish] render if I was able to quickly open another tab (page) to bash.org (just an example) while I wait for the other one to load.

But this makes emulation software such as Wine a lost hope, doesn't it? Because Windows apps access the Thread Information Block (TIB) via %gs (%fs on ia32). Anyway, my so called small program is actually a Win64 emulator and I need the segment selector to stay put across syscalls. It works like a charm on single threaded apps, but as soon as I spawn a thread, all hell breaks loose :) I've managed to come up with something that *kind of* works. It goes like this: void my_handler( int s ) { if ( s == SIGSEGV ) { if ( get_gs() == 0 ) { amd64_set_gsbase(); } else { signal( SIGSEGV, SIG_DFL ); } } } int my_init( void ) { /* alloc TIB memory and initialize */ amd64_set_gsbase( lpTIB ); signal( SIGSEGV, my_handler ); return 0; } but after a series of dlopen()-s, my_handler() is called without %gs being zero and without a valid fault (the handler does not get recalled after signal( SIGSEGV, SIG_DFL ). I'm still working on this aspect ... In fact, you should not use amd64_set_gsbase() directly. If you *really* have to mess up with base addresses, you have to use sysarch(2) syscall, i.e., sysarch(AMD64_SET_GSBASE, args). I found this: /usr/src/lib/libc/amd64/sys/amd64_set_gsbase.c:32 int amd64_set_gsbase(void *addr) { return (sysarch(AMD64_SET_GSBASE, addr)); } and this (man 2 sysarch()): The sysarch() system call should never be called directly by user programs. Instead, they should access its functions using the architecture-dependent library. Who am I suppose to believe? :) However, it only changes the base address via MSR, i.e., %gs itself has no meaning. Maybe, but the selector loaded in %gs *does* have meaning. Anyway, the thing is I _have_ to make this work.
