Subject: Re: [PATCHSET] block: fix PIO cache coherency bug
Date: Tue, 30 May 2006 20:57:29 -0400 (EDT) [thread overview]
Message-ID: <20060530.205729.73666677.davem@redhat.com> (raw)
In-Reply-To: <Pine.LNX.4.60.0605302301280.6213@poirot.grange>
The IDE string ops need to flush the cache. We've been doing that
on sparc64 for more than 5 years... Otherwise, PIO transfers do
not "behave" like DMA.
