More or less unexisting. The very same candidates that would cause one to remain on a IA32 user land because of non-free cruft on Linux mostly also holds FreeBSD as it is typically the very same software people want to run through the Linux emulation layer. Think of Flash and Google Earth for example. That said I have no use for kfreebsd on a desktop and I hence didn't try any of those programs under kfreebsd so far. > Another likely difference is that kFreeBSD in PAE mode has major > drawbacks (in particular we'd have to disable a bunch of drivers, see > sys/i386/conf/PAE and URL I pasted before). All in all, I have the > impression that using PAE would be unacceptable for the majority of > i686 users. That on the other hand is a good rationale not to use PAE. However, if you read the discussion I noted there is no significant performance improvement [on Linux] to use i686 over i486. Thus, users of 686 capable CPUs may happily use the 486 branch, whereas people who need PAE need 686 anyway. > Good question. TBH I really dislike adding new flavours for PAE > unless SMP is merged.

We're not freezing tomorrow, maybe consider waiting for upstream regarding SMP support upstream. > I don't know if SMP option is really usable on uniprocessor hardware. > FWIW, I've tested -smp flavours for 8.3 and 9.0 on an uniprocessor VM > and both seem to work fine. I would hope it is usable. If it weren't that would certainly be a bug in the SMP code. However, there might be design decisions that make SMP slower on uniprocessor hardware (or not - I don't know as said). > Maybe we should discuss this with FreeBSD? We could even propose them > to make SMP the default there. That makes sense, yes. In particular I guess we shouldn't be inventing use cases which aren't supported in such a configuration upstream either. > Given that a PAE kernel has important drawbacks (like disabling a lot > of drivers), I'd rather leave it to the user to explicitly install > those kernels after a normal kFreeBSD is running. I wrote that under the impression that such a kernel would crash on systems with more than 4G RAM. That would leave people without possibility to install kfreebsd. If that's sorted out, i.e. the bug has been fixed I am for a non PAE kernel too. I do not think there would be any benefit to use >= 4G RAM in the context of D-I. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBAgAGBQJO7LFbAAoJEMcrUe6dgPNtMjQP/ArffA1pH++cbXkYrYKtDuWr gSE/lPpPE8039iEfMIwlma3GE47YxYSf41L57dSfThnZ2nBtTMbt7QDuG+g1dEca s9a5tuIf0QmruwNeiOkhFmxnowPbwmfrORGLS69caJYjc85pjfVQJD56NnB50pcO j8fkr4DyqvG8wqzzSmkkOutaSHkwUm3UbZaemchA2OYlaP20NbhVzkGj9Ze36Nnx 2mYSj8F2XvwzlYwhUqT9puJlSfWCgeWYXQmoGw1+yo8rudkEN7aApUsrADUc4wi6 jP5TxykGtVoZm0Nd0q/+gPhBoddevQZs0afaXGUpltdGxXdw0SjdNWuQfLbqdxtF q6CwTiSEevIirf7+Tqaqo60GVScWr6fwGMw5SnU98FC9lElDUJokN2/DWzeTfBW0 duwyC7lGqOlKeIzCbRYj/KOJDOEh7uT5kBXcD/Em18hBzC86ypjQZeYDOTrhJ+Jp FNkjoQ+iGC9l1hC/sUWkEsSgX0MDFMGv8RAJ4kp42MAZZb4zl+6keDsU4L3/pgBA Zc1Vlm9YmxkjAwqDD4NZWsUGsL8T2AgiZXO9oYU3Whgk2jfhStqq/d5hBmwOzbvy hgx4dtGpdgsmfaaMts+uw66D0cHh6cag0w6WE0QgnXUhayW/yAVSZJpU7dS0NVIS 4gdTDnXPmAmF9TH+qWDr =E/Ed -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to debian-bsd-requ...@lists.debian.org with a subject of "unsubscribe".
