hvisor-v0.3 Key Changes Summary

What's Changed

• 🐞 fix(iommu, its): fix its bugs by @ZhongkaiXu in #200
• x86_64: Add support for QEMU Q35 and ASUS NUC14MNK by @Solicey in #204

New Features and Hardware Support

🖥️ x86_64 Platform Support

Added comprehensive support for the x86_64 architecture, including:

• QEMU Q35 virtual platform: Boot and run guest Linux with full virtualization features.
• ASUS NUC14MNK physical platform: Verified root and non-root Linux boot on real hardware.
• Enabled SMP (multi-core startup).
• Enabled virtio-blk, virtio-net, and virtio-console devices in non-root Linux.
• Implemented VMX & EPT virtualization.

🧱 IOMMU & ITS Improvements (AArch64)

Refined and stabilized interrupt and I/O virtualization subsystems:

• Introduced dedicated IOMMU page table (iommu-pt) instead of reusing CPU page tables — improving address space isolation and DMA security.
• Fixed GITS_CBASER and GITS_BASER (Device Table) emulation logic to resolve ITS “non-stick” state issues.
• Enabled MSI (Message Signaled Interrupts) in zone1-linux.dts for full PCI/virtio interrupt support in secondary domains.

Contributors

• @Solicey — x86_64 platform bring-up and hardware support
• @ZhongkaiXu — IOMMU & ITS fixes for AArch64
