This series enable x2APIC support for AMD platform by enabling AMD IOMMU XT mode to allow interrupt remapping with 32-bit destination APIC ID.
For full x2APIC support, the following patches are also required (already available in v4.18-rc1) * 6c4f5abaf356 ("x86/CPU: Modify detect_extended_topology() to return result") * 3986a0a805e6 ("x86/CPU/AMD: Derive CPU topology from CPUID function 0xB when available")
Thanks, Suravee
Changes from V1 (https://lkml.org/lkml/2018/6/22/645): * 3/3: Declare the variable amd_iommu_xt_mode as static (per kbuild test robot)
Suravee Suthikulpanit (3): x86: irq_remapping: Move irq remapping mode enum iommu/amd: Add support for higher 64-bit IOMMU Control Register iommu/amd: Add support for IOMMU XT mode
