🎊 Hyperion Kernel Changes

🖥️ KVM Enhancements

• CONFIG_KVM_ASYNC_PF — avoids vCPU stalls on page faults, boosting performance for over-committed or ballooned guest RAM.
• CONFIG_KVM_COMPAT — adds 32-bit compat ioctls for older libvirt/QEMU versions.
• CONFIG_KVM_AMD_SEV_SNP — enables Secure Nested Paging (EPYC 3rd gen+), authenticating guest memory.

🎮 VFIO / Passthrough

• CONFIG_VFIO_PCI_VGA — supports VGA/display passthrough for Looking Glass or single-GPU setups.

⚡ VHOST & VirtIO

• CONFIG_VHOST_IOTLB + CONFIG_VHOST_RING — foundational vhost infrastructure for vhost-user and vDPA.
• CONFIG_VIRTIO_MMIO + CONFIG_VIRTIO_MMIO_CMDLINE_DEVICES — VirtIO over MMIO for microVMs or direct-boot QEMU guests.
• CONFIG_VIRTIO_PMEM — VirtIO NVDIMM/DAX support for persistent memory.
• CONFIG_VIRTIO_DMA_SHARED_BUFFER — zero-copy DMA-BUF sharing for virgl/virtio-gpu workloads.

🔐 Memory Encryption & IOMMU

• CONFIG_X86_MEM_ENCRYPT — umbrella for SEV/SME/TME support.
• CONFIG_AMD_MEM_ENCRYPT (with AMD_MEM_ENCRYPT_ACTIVE_BY_DEFAULT=n) — AMD SME/SEV/SEV-ES host support.
• CONFIG_INTEL_TDX_GUEST — boot as Intel TDX trust domain guest.

📱 Android / Waydroid Support

• CONFIG_ANDROID_BINDER_IPC_SELFTEST — off for binder debugging.
• Full Waydroid/LXC container checklist included: binder, squashfs, overlayfs, erofs, namespaces, cgroups, PSI, bridge/NAT, vsock — all built-in.
