Bring in geom(8) utility. It is an universal utility for operating on GEOM classes. It works by loading a shared library via dlopen(3) mechanism with class-specific code, it is also responsible for communicating with GEOM via libgeom(3). Per-class shared libraries are going to be stored in /lib/geom/ directory. It provides also few standard commands like 'list', 'load' and 'unload' for existing classes which aren't aware of geom(8). More info will be send on freebsd-current@ mailing list. Supported by: Wheel - Open Technologies - http://www.wheel.pl 2004-05-20 10:09:56 +00:00			`# $FreeBSD$`

Reimplementation of world/kernel build options. For details, see: http://lists.freebsd.org/pipermail/freebsd-current/2006-March/061725.html The src.conf(5) manpage is to follow in a few days.

A GEOM cache can speed up read performance by sending fixed size read requests to its consumer. It has been developed to address the problem of a horrible read performance of a 64k blocksize FS residing on a RAID3 array with 8 data components, where a single disk component would only get 8k read requests, thus effectively killing disk performance under high load. Documentation will be provided later. I'd like to thank Vsevolod Lobko for his bright ideas, and Pawel Jakub Dawidek for helping me fix the nasty bug. 2006-10-06 08:27:07 +00:00			`SUBDIR= cache`

I think I found the problem, reconnect geli to the build. 2005-07-27 23:56:32 +00:00			`SUBDIR+=eli`
Add missing check for the NO_CRYPT build option. Reported by: Alexander Polakov 2005-08-02 20:12:30 +00:00			`.endif`
Hook up gjournal bits to the build. Sponsored by: home.pl 2006-10-31 22:22:30 +00:00			`SUBDIR+=journal`
Introduce GEOM_LABEL class. This class is used for detecting volume labels on file systems: UFS, MSDOSFS (FAT12, FAT16, FAT32) and ISO9660. It also provide native labelization (there is no need for file system). g_label_ufs.c is based on geom_vol_ffs from Gordon Tetlow. g_label_msdos.c and g_label_iso9660.c are probably hacks, I just found where volume labels are stored and I use those offsets here, but with this class it should be easy to do it as it should be done by someone who know how. Implementing volume labels detection for other file systems also should be trivial. New providers are created in those directories: /dev/ufs/ (UFS1, UFS2) /dev/msdosfs/ (FAT12, FAT16, FAT32) /dev/iso9660/ (ISO9660) /dev/label/ (native labels, configured with glabel(8)) Manual page cleanups and some comments inside were submitted by Simon L. Nielsen, who was, as always, very helpful. Thanks! 2004-07-02 19:40:36 +00:00			`SUBDIR+=label`

Bring in geom(8) utility. It is an universal utility for operating on GEOM classes. It works by loading a shared library via dlopen(3) mechanism with class-specific code, it is also responsible for communicating with GEOM via libgeom(3). Per-class shared libraries are going to be stored in /lib/geom/ directory. It provides also few standard commands like 'list', 'load' and 'unload' for existing classes which aren't aware of geom(8).
