[PATCH v6] hw/arm/virt: Support larger highmem MMIO regions

2025-02-21 Thread Matthew R. Ochs
The MMIO region size required to support virtualized environments with large PCI BAR regions can exceed the hardcoded limit configured in QEMU. For example, a VM with multiple NVIDIA Grace-Hopper GPUs passed through requires more MMIO memory than the amount provided by VIRT_HIGH_PCIE_MMIO (currentl
