Complete microkernel boot pipeline: adapter loads only init + storage + display from disk. Init bootstraps all other servers by reading binaries from the storage server via IPC, parsing ELF, creating processes, mapping pages, and spawning threads. New syscalls: - CreateEndpoint: userspace endpoint creation with full capability grant - DebugPutchar: debug output to UART from userspace - MapPage: cross-process page mapping (init loads binaries into children) - SpawnThreadIn: spawn thread in another process via capability Key fixes: - Per-process L1 page tables for VPN[2]=0 (prevents cross-process corruption) - Separate kernel_pt from page_tables[0] (init pid=0 overwrote kernel PT ref) - Thread Running state set in switch_to_next (syscalls rejected without it) - Pending IPC results applied during context switch - SIE disabled during boot (timer can't preempt into unready processes) - User heap VA starts at 0x40000 (avoids shared buffer at 0x30000) - RequestPages maps at user VAs via per-process heap allocator VirtIO GPU: - Adapter probes for GPU device, initializes resource/scanout/backing - Display server writes to mapped framebuffer, flushes via GPU virtqueue - 640x480 BGRA framebuffer with transfer-to-host and resource-flush Storage server: - Userspace VirtIO block driver using pre-mapped MMIO and DMA pages - FAT16 filesystem reader serving file-read requests via IPC - Shared buffer protocol: init writes filename, storage writes file data Echo app for IPC testing (adapter-loaded echo proved the pipeline end-to-end).
