[PATCH 2/3] iommu/vt-d:Add support for probing ACPI device in RMRR

2020-08-26 Thread FelixCuioc
After acpi device in RMRR is detected,it is necessary to establish a mapping for these devices. In acpi_device_create_direct_mappings(),create a mapping for the acpi device in RMRR. Add a helper to achieve the acpi namespace device can access the RMRR region. Signed-off-by: FelixCuioc --- driver
