Subject: Re: [patch] My AMD IDE driver, v2.7
Date: Mon, 11 Mar 2002 23:26:30 -0500 [thread overview]
Message-ID: <3C8D8376.8010907@mandrakesoft.com> (raw)
In-Reply-To: <Pine.LNX.4.33.0203111944090.18649-100000@penguin.transmeta.com>
Your proposal sounds 100% ok to me...
For the details of the userspace interface (for both ATA and SCSI), my
idea was to use standard read(2) and write(2).
Any number of programs can open /dev/ata/hda/control or
/dev/scsi/sdc/control. write(2) submits requests, read(2) consumes
command responses, perhaps buffering a bit so that multiple responses
are not lost if userspace is slow.
Maybe it's a cheesy way to avoid ioctl(2), maybe not...
Jeff
