Subject: [PATCH 4/5] iommu/amd: Check for irq-remap support amd_iommu_prepare()
Date: Mon, 15 Dec 2014 16:13:23 +0100 [thread overview]
Message-ID: <1418656404-28575-5-git-send-email-joro@8bytes.org> (raw)
In-Reply-To: <1418656404-28575-1-git-send-email-joro-zLv9SwRftAIdnm+yROfE0A@public.gmane.org>
From: Joerg Roedel <jroedel-l3A5Bk7waGM@public.gmane.org>
This allows to get rid of the irq_remapping_supported()
function and all its call-backs into the Intel and AMD
IOMMU drivers.
