Package: kfreebsd-image-8.1-1-amd64 Version: 8.1-5 Severity: wishlist Tags: d-i patch
Please increase NKPT on amd64. The maximum size of mfsroot is correlated [1] with NKPT definition in pmap.h. Default NKPT value on amd64 (32) results in a limit of approximately 47 MiB, which is not enough to fit netboot-gtk images. I determined through trial and error that the limit with NKPT=44 is slightly above 64 MiB, giving enough space for the netboot-gtk data and a few free MiB for use during D-I run. I believe that increasing NKPT on amd64 is harmless, as it will just increase the size of a statically-allocated page index. On i386, however, it seems VERY PROBLEMATIC because of the limited VM space, I would recommend discarding the netboot-gtk option on kfreebsd-i386. [1] I think it's a linear relation, but I don't know the formula. -- System Information: Debian Release: squeeze/sid APT prefers testing APT policy: (500, 'testing') Architecture: kfreebsd-amd64 (x86_64) Kernel: kFreeBSD 8.1-1-amd64 Locale: LANG=ca_AD.UTF-8, LC_CTYPE=ca_AD.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages kfreebsd-image-8.1-1-amd64 depends on: ii freebsd-utils 8.1-1 FreeBSD utilities needed for GNU/k ii kldutils 8.1-1 tools for managing kFreeBSD module kfreebsd-image-8.1-1-amd64 recommends no packages. kfreebsd-image-8.1-1-amd64 suggests no packages. -- no debconf information
