It is not usable yet as the write will not perform any deletes from the device, either the file system or another geom will have to issue a BIO_DELETE followed by BIO_WRITE's to write to the disk. This is done to support NAND flash aware file systems. TODO: * ECC support. * Add GEOM attributes to get information about the NAND device out, eg.

As I had written most of the code already I felt it would be better to release it now than during the middle of the Summer of Code so if the student is accepted they could work on the existing code base rather than duplicating work I have already done. There is still a lot of work to do on the driver before it is usable including getting it working on real hardware.

Yes, this is intentional as NAND flash is split up to blocks. The blocks are then split into pages. You have to erase the entire block at a time but can write pages as required. A file system that knows about this difference will be able to talk to nand(8) directly. > > > TODO: > > * ECC support. > > * Add GEOM attributes to get information about the NAND device out, > > eg.

A file system that knows about > this difference will be able to talk to nand(8) directly. What I know about file systems and UFS is pretty limited, so forgive me if what follows are silly questions. Are there any defragmentation routines in UFS that could/should be disabled when using it on a flash device? I know a file system can be optimized for space or time with tunefs(8). I imagine optimizing for space would be best for a flash device? Is there anything else other than that and your work that can improve flash support?

I have here problem with msdosfs formatted usb, with label consits of russian symbols "Š ŃƒŃŃ" when I hook this usb, my System (which is PC-BSD 7.1) became unuseable; the label file created in /dev/msdosfs, but symbols are wrong there, and ls /dev/msdosfs report that there a file, and it's not found. When I plug in this usb, xorg have some problmes, and couldn't be restarted for no particular reason (couldn't find out something in xorg logs) From owner-freebsd-geom@FreeBSD.ORG Sat Apr 11 22:10:28 2009 Return-Path: Delivered-To: freebsd-geom@hub.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id 4BB2F1065670; Sat, 11 Apr 2009 22:10:28 +0000 (UTC) (envelope-from linimon@FreeBSD.org) Received: from freefall.freebsd.org (freefall.freebsd.org [IPv6:2001:4f8:fff6::28]) by mx1.freebsd.org (Postfix) with ESMTP id 20A0F8FC0A; Sat, 11 Apr 2009 22:10:28 +0000 (UTC) (envelope-from linimon@FreeBSD.org) Received: from freefall.freebsd.org (linimon@localhost [127.0.0.1]) by freefall.freebsd.org (8.14.3/8.14.3) with ESMTP id n3BMASpi095350; Sat, 11 Apr 2009 22:10:28 GMT (envelope-from linimon@freefall.freebsd.org) Received: (from linimon@localhost) by freefall.freebsd.org (8.14.3/8.14.3/Submit) id n3BMARov095346; Sat, 11 Apr 2009 22:10:27 GMT (envelope-from linimon) Date: Sat, 11 Apr 2009 22:10:27 GMT Message-Id: <200904112210.n3BMARov095346@freefall.freebsd.org> To: linimon@FreeBSD.org, freebsd-bugs@FreeBSD.org, freebsd-geom@FreeBSD.org From: linimon@FreeBSD.org Cc: Subject: Re: kern/133604: [gvinum] [panic] writing to gjournal on a gvinum volume X-BeenThere: freebsd-geom@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: GEOM-specific discussions and implementations List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 11 Apr 2009 22:10:29 -0000 Old Synopsis: [panic] writing to gjournal on a gvinum volume New Synopsis: [gvinum] [panic] writing to gjournal on a gvinum volume Responsible-Changed-From-To: freebsd-bugs->freebsd-geom Responsible-Changed-By: linimon Responsible-Changed-When: Sat Apr 11 22:10:10 UTC 2009 Responsible-Changed-Why: Over to maintainer(s). http://www.freebsd.org/cgi/query-pr.cgi?pr=133604
