Subject: [PATCH v8 1/8] hw/vfio/common: Remove error print on mmio region translation by viommu
Date: Wed, 18 Mar 2020 15:41:52 +0530 [thread overview]
Message-ID: <20200318101159.8767-2-bbhushan2@marvell.com> (raw)
In-Reply-To: <20200318101159.8767-1-bbhushan2@marvell.com>
On ARM, the MSI doorbell is translated by the virtual IOMMU.
As such address_space_translate() returns the MSI controller
MMIO region and we get an "iommu map to non memory area"
message. Let's remove this latter.
