From: Poul-Henning Kamp Date: Mon, 29 Nov 1999 21:39:56 +0100 Message-ID: <23112.943907996@critter.freebsd.dk> Sender: owner-freebsd-small@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hi gang, I'm looking for input from this crowd: what features do you want to see from the md driver ? Currently it supports two modes of operation: 1. Preloaded images. This is like MFS_ROOT basically, but you can muliple images and get multiple devices. 2. Malloc mode. Here storage is malloc(9)'ed on as needed basis and freed back when possible (with UFS for instance). Simple compression is performed: if a sector have all bytes identical no storage will be alocated, only that byte value will be stored. I would like to hear from the embedded people what you need from a memory device driver in FreeBSD in the future.
