- Vision: Updated NexShell section with VirtIO-GPU transport detail - Canvas: Implemented framebuffer.zig (800x600x32bpp in BSS) - Retina: Implemented gpu.zig VirtIO-GPU MMIO driver - Device probing across MMIO slots 0x10001000-0x10008000 - Support for VirtIO MMIO v1 (legacy) and v2 (modern) - Queue setup with PFN for legacy devices - 2D Resource creation, backing attachment, scanout setup - Integration: UI fiber now calls virtio_gpu_flush() after render - Status: GPU detected at 0x10008000 (DevID=16), queue initialized - Remaining: Debug command/response polling (hangs on first command) |

Architecture Independence
This folder contains no architecture-specific code. All platform-specific
details are handled by the HAL layer (../hal/).
Compile-time architecture selection uses Nim's when defined():
when defined(amd64):
const CONTEXT_SIZE = 56
elif defined(arm64):
const CONTEXT_SIZE = 96
elif defined(riscv64):
const CONTEXT_SIZE = 112
Dependencies
