Subject: IO buffer alignment for block devices
Date: Mon, 13 Sep 2004 15:48:41 +0300 [thread overview]
Message-ID: <41459729.5060106@il.marvell.com> (raw)
Hi,
Is there any minimal alignment for the IO buffers (sg and single)
sent to a scsi LLD?
I found that buffers that come from buffer cache, page cache and sg
are page aligned , and the raw driver send sector aligned buffers.
so can I assume that the minimal alignment of the buffer is 512 bytes?
thanks
saeed
