Actually NetBSD has (or at least used to) use their ability to have separate page free lists to only ever allocate pvo entries from them low 256MB of RAM. At least that's how I read it. This meant that only direct-mapping the low 256MB worked fine as that's where all the pvo entries were. Thanks for coming up with a solution for this. =) -- Benno Rice benno@FreeBSD.org [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (FreeBSD) iD8DBQA9XEemXjRwWofFmQkRAj8YAJ9yI32ssFpm0nPhNjCQlR/nXoUVCQCePz00 ig/8DRiGAXObtpz819skCLU= =kQd9 -----END PGP SIGNATURE-----home | help
