Subject: [PATCH v2 0/2] Intel-IOMMU: source-id checking for interrupt remapping
Date: Wed, 20 May 2009 02:31:50 +0800	[thread overview]
Message-ID: <1242757912-6041-1-git-send-email-weidong.han@intel.com> (raw)

Support source-id checking for interrupt remapping, and then
isolates interrupts for guests/VMs with assigned devices.

v1 -> v2 change log:
	Access PCI directly (read_pci_config_byte) to parse IOAPIC,
instead of PCI related discovery, because PCI subsystem is not
initialized at that time.

Weidong Han (2):
  Intel-IOMMU, intr-remap: set the whole 128bits of irte when
    modify/free it
