From mboxrd@z Thu Jan 1 00:00:00 1970 From: David Yeu Subject: SCSI Emulation w/ DMA Date: Mon, 19 Aug 2002 16:57:48 -0500 Sender: linux-newbie-owner@vger.kernel.org Message-ID: <3D6169DC.1020700@tulane.edu> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Return-path: List-Id: Content-Type: text/plain; charset="us-ascii"; format="flowed" To: linux-newbie@vger.kernel.org Hi everyone, I have SCSI emulation on my CDR drive in order to burn and the like, but I was confused by the following entries in /var/log/messages... ---------------------------------------------------------------------- Aug 5 12:18:48 localhost kernel: SCSI subsystem driver Revision: 1.00 Aug 5 12:18:19 localhost rc.sysinit: Setting clock (localtime): Mon Aug 5 12:18:13 UTC 2002 succeeded Aug 5 12:18:49 localhost kernel: scsi0 : SCSI host adapter emulation for IDE ATAPI devices Aug 5 12:18:19 localhost rc.sysinit: Loading default keymap succeeded Aug 5 12:18:49 localhost kernel: Vendor: LITE-ON Model: LTR-24102B Rev: 5S0J Aug 5 12:18:19 localhost rc.sysinit: Setting default font (lat0-sun16): succeeded Aug 5 12:18:49 localhost kernel: Type: CD-ROM ANSI SCSI revision: 02 Aug 5 12:18:19 localhost rc.sysinit: Activating swap partitions: succeeded Aug 5 12:18:49 localhost kernel: hdc: DMA disabled ----------------------------------------------------------------------- The last line says that DMA is disabled, but it refers to hdc. Since my /dev/cdrom is linked to /dev/scd0, and /dev/cdrecorder is linked to /dev/sg0, does that mean DMA is working anyhow? How can I tell? (I was prompted into peeking around after burning seemed a little slow..)
