Initial commit: Open-IOV vGPU-IO complete stack

- 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

+ * NVA0BD_CTRL_CMD_NVFBC_SW_SESSION_UPDATE_INFO
+ *
+ * This command is used to let RM know about runtime information about
+ * NVFBC session on given GPU.
+ *  *
+  *   hResolution
+ *     This parameter specifies the current horizontal resolution of NVFBC session.
+ *   vResolution
+ *     This parameter specifies the current vertical resolution of NVFBC session.
+ *   captureCallFlags
+ *     This field specifies the flags associated with the capture call and the session.
+ *     One of the flags specifies whether the user made the capture with wait or not.
+ *   totalGrabCalls
+ *     This field specifies the total number of grab calls made by the user.
+ *   averageLatency
+ *     This field specifies the average capture latency over last 1 second.
+ *   averageFPS
+ *     This field specifies the average frames captured.
+  *   timestampEntryCount
+ *     This field specifies the number of entries in the timestampEntry array.
+ *     It should not be greater than NVA0BD_CTRL_CMD_NVFBC_MAX_TIMESTAMP_ENTRIES.
+ *     When this field is zero, RM will assume that client has calculated averageFBCFps
+ *     and averageFBCLatency, thus ignore timestampEntry array.
+ *   timestampEntry
+ *     This field specifies a array holding capture timestamps in microseconds.
+ *
+ * Possible status values returned are:
+ *   NV_OK
+ *   NV_ERR_INVALID_ARGUMENT
