Subject: Re: [patch 6/7] SDHCI: Check DMA for overruns at end of transfer
Date: Mon, 3 Nov 2008 19:12:00 -0200 [thread overview]
Message-ID: <20081103211200.GA10721@khazad-dum.debian.net> (raw)
In-Reply-To: <20081103201010.820070757@fluff.org.uk>
Maybe I didn't understand it right, but if the DMA controller could overrun
a buffer, don't you ALSO need to add defensive padding (i.e. increase the
buffer) to make sure nothing important gets overrun?
