From mboxrd@z Thu Jan 1 00:00:00 1970 From: Pavel Fedin Subject: [PATCH 0/3] Introduce MSI hardware mapping for VFIO Date: Tue, 24 Nov 2015 10:48:18 +0300 Message-ID: Return-path: Sender: kvm-owner@vger.kernel.org To: kvm@vger.kernel.org, kvmarm@lists.cs.columbia.edu Cc: Alex Williamson , Marc Zyngier , Thomas Gleixner , Jason Cooper , Manish Jaggi List-Id: kvmarm@lists.cs.columbia.edu On some architectures (e.g. ARM64) if the device is behind an IOMMU, and is being mapped by VFIO, it is necessary to also add mappings for MSI translation register for interrupts to work. This series implements the necessary API to do this, and makes use of this API for GICv3 ITS on ARM64.
