Subject: [Qemu-devel] [PATCH][RFC] Propogate the PCI device info till IOMMU
Date: Mon, 18 May 2015 14:03:01 +0530	[thread overview]
Message-ID: <1431937982-31941-1-git-send-email-pmallapp@broadcom.com> (raw)

From: Prem Mallappa <pmallapp@broadcom.com>

ARM SMMU requires PCI read/write memory requestors' Identification. This
will propogate the "Device" information all the way till IOMMU device.
ARM SMMU uses the device's ARID to index into tables on a per device basis.
The ARM SMMU v3 device emulation will follow this patch sometime soon.
