| * | Phase 3: RPC Handler Completion | Arthur Hanson Rasmusson | 2026-09-13 |
| | | | | | | | | | | | | | | - Enhanced gsp_rpc_client.c with proper emulation implementations: - ALLOC/FREE: VRAM allocation tracking with host page allocation and DMA mapping - MAP/UNMAP: GPU VA mapping management - PIN/UNPIN: DMA address retrieval for pinned pages - SCHEDULE/YIELD: Local workqueue-based scheduling - NOTIFY: Callback registration for async events - Added emulation function declarations to gsp_rpc_client.h - Exported nv_vgpu_simple_mapping struct in memory.h for cross-file use - Updated RPC handlers to use gsp_rpc_emulation_is_enabled() accessor - All 12 RPC types now have functional emulation fallbacks | ||
| * | Initial commit: Open-IOV vGPU-IO complete stack | Arthur Hanson Rasmusson | 2026-09-13 |
| - Firmware decompilation: GSP 570.144W (28.5MB ELF, RV64IMAC), 132 decompiled C files - Kernel modules: nvidia.ko (34MB, OpenRM), open-iov-vfio.ko (2.8MB, VFIO mdev), gsp-vgpu.ko (1.8MB, guest driver) - Userspace: libiov.so/libvgpu.so (76KB), example_vgpu (28KB), rpc_emulator.c - PCI config space emulation (256B with PM, MSI, MSI-X, PCIe caps) - 12 RPC types fully mapped from firmware decompilation - BAR trap, WPR, scheduling, notification, migration emulation - Helper scripts: load_vgpu_stack, create_mdev, launch_qemu_vgpu, test_vgpu_stack, setup_guest_driver, unload_vgpu_stack - Architecture documentation - Wiki: 10 technical documents - Git LFS for large binaries (.ko, .bin, .iso, .img, .o, ghidra repos) - nvidia-open-gpu-kernel-modules as submodule | |||
