Subject: [PATCH 4/4] Intel pci: Use coherent DMA mask when requested
Date: Thu, 07 Apr 2011 12:52:00 -0700 [thread overview]
Message-ID: <4D9E15E0.5060000@sgi.com> (raw)
In-Reply-To: <20110329233602.272459647@gulag1.americas.sgi.com>
The __intel_map_single function is not honoring the passed in
DMA mask. This results in not using the coherent DMA mask when
called from intel_alloc_coherent().
