[Qemu-devel] [PATCH][RFC] Propogate the PCI device info till IOMMU

Subject: [Qemu-devel] [PATCH][RFC] Propogate the PCI device info till IOMMU
Date: Mon, 18 May 2015 12:08:20 +0530

From: Prem Mallappa <address@hidden>

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.

  PCI: Added new API which propogates the DMA initiator info
