Subject: [PATCH 2/2] swiotlb-xen: pass dev_addr to swiotlb_tbl_unmap_single
Date: Fri, 21 Nov 2014 17:00:20 +0000 [thread overview]
Message-ID: <1416589220-7720-2-git-send-email-stefano.stabellini@eu.citrix.com> (raw)
In-Reply-To: <alpine.DEB.2.02.1411211657430.2675@kaball.uk.xensource.com>
Need to pass the pointer within the swiotlb internal buffer to the
swiotlb library, that in the case of xen_unmap_single is dev_addr, not
paddr.
