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

+ * NV0073_CTRL_CMD_EVENT_SET_NOTIFICATION
+ *
+ * This command sets event notification state for the associated display
+ * object.  This command requires that an instance of NV01_EVENT has been
+ * previously bound to the associated display object.
+ *
+ *   subDeviceInstance
+ *     This parameter specifies the subdevice instance within the
+ *     NV04_DISPLAY_COMMON parent device to which the operation should be
+ *     directed.  This parameter must specify a value between zero and the
+ *     total number of subdevices within the parent device.  This parameter
+ *     should be set to zero for default behavior.
+ *   hEvent
+ *     This parameter specifies the handle of the NV01_EVENT instance
+ *     to be bound to the given subDeviceInstance.
+ *   event
+ *     This parameter specifies the type of event to which the specified
+ *     action is to be applied.  This parameter must specify a valid
+ *     NV0073_NOTIFIERS value (see cl0073.h for more details) and should
+ *     not exceed one less NV0073_NOTIFIERS_MAXCOUNT.
+ *   action
+ *     This parameter specifies the desired event notification action.
+ *     Valid notification actions include:
+ *       NV0073_CTRL_SET_EVENT_NOTIFICATION_DISABLE
+ *         This action disables event notification for the specified
+ *         event for the associated subdevice object.
+ *       NV0073_CTRL_SET_EVENT_NOTIFICATION_SINGLE
+ *         This action enables single-shot event notification for the
+ *         specified event for the associated subdevice object.
+ *       NV0073_CTRL_SET_EVENT_NOTIFICATION_REPEAT
+ *         This action enables repeated event notification for the specified
+ *         event for the associated system controller object.
+ *
+ * Possible status values returned are:
+ *   NV_OK
+ *   NV_ERR_INVALID_PARAM_STRUCT
+ *   NV_ERR_INVALID_ARGUMENT
+ *   NV_ERR_INVALID_STATE
