[PATCH 0/3] iommu/amd: Enable x2APIC support

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_topolo

[PATCH 1/3] x86: irq_remapping: Move irq remapping mode enum

The enum is currently defined in Intel-specific DMAR header file, but it is also used by APIC common code. Therefore, move it to a more appropriate interrupt-remapping common header file. This will also be used by subsequent patches. Cc: Thomas Gleixner Cc: Ingo Molnar Cc: Joerg Roedel Signed-o

[PATCH 2/3] iommu/amd: Add support for higher 64-bit IOMMU Control Register

Currently, the driver only supports lower 32-bit of IOMMU Control register. However, newer AMD IOMMU specification has extended this register to 64-bit. Therefore, replace the accessing API with the 64-bit version. Cc: Joerg Roedel Signed-off-by: Suravee Suthikulpanit --- drivers/iommu/amd_iomm

[PATCH 3/3] iommu/amd: Add support for IOMMU XT mode

The AMD IOMMU XT mode enables interrupt remapping with 32-bit destination APIC ID, which is required for x2APIC. The feature is available when the XTSup bit is set in the IOMMU Extended Feature register and/or the IVHD Type 10h IOMMU Feature Reporting field. For more information, please see sectio
