# test-iommu-qemu.sh - Launch QEMU with AMD IOMMU device for hardware testing
|
|
#
|
|
# This wrapper adds the AMD IOMMU device to QEMU for testing IOMMU/vIOMMU
|
|
# functionality on AMD hardware. It forwards any additional QEMU flags to the
|
|
# make qemu invocation.
|
|
#
|
|
# Usage:
|
|
# ./local/scripts/test-iommu-qemu.sh [--help]
|
|
# ./local/scripts/test-iommu-qemu.sh [extra QEMU flags...]
|
|
#
|
|
# Examples:
|
|
# ./local/scripts/test-iommu-qemu.sh # Basic IOMMU test
|
|
# ./local/scripts/test-iommu-qemu.sh -display sdl # With SDL display
|
|
# ./local/scripts/test-iommu-qemu.sh -m 4G # With 4GB RAM
