- Introduced ConsoleTxBatcher to coalesce UART transmission into larger chunks, improving performance and reducing syscall overhead.
- Updated Aarch64 and x86_64 machine models to utilize the new batcher for UART output.
- Implemented IRQFD support in the VmIoLoop for efficient interrupt handling on Linux, allowing direct assertion of interrupt lines from the hypervisor.
- Enhanced the virtio_mmio device to support IRQFD mode, improving responsiveness and reducing latency in interrupt-driven scenarios.
