[Xen-devel] [Patch] Remove a panic condition in enabling x2APIC
Currently Xen triggers a panic if user disables VT-d by command line while not disable x2APIC. This requires users to specify both "iommu=0" and "x2apic=0" to disable VT-d if the platform supports x2APIC. It''s not user friendly. This patch removes the panic condition. That''s to say, don''t require user to specify "x2apic=0" when specify "iommu=0". As long as VT-d is not enabled (disabled in BIOS or in command line), x2APIC won''t be enabled naturally (x2APIC depends on VT-d Interrupt remapping).
