Subject: [PATCH v6 1/5] vfio/mdev: Register mdev bus earlier during boot
Date: Fri, 30 Oct 2020 12:58:05 +0800 [thread overview]
Message-ID: <20201030045809.957927-2-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20201030045809.957927-1-baolu.lu@linux.intel.com>
Move mdev bus registration earlier than IOMMU probe processing so that
the IOMMU drivers could be able to set iommu_ops for the mdev bus. This
only applies when vfio-mdev module is setected to be built-in.
