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

+ * NV0080_CTRL_CMD_HOST_GET_CAPS
+ *
+ * This command returns the set of host capabilities for the device
+ * in the form of an array of unsigned bytes.  Host capabilities
+ * include supported features and required workarounds for the host-related
+ * engine(s) within the device, each represented by a byte offset into
+ * the table and a bit position within that byte.
+ *
+ *   capsTblSize
+ *     This parameter specifies the size in bytes of the caps table.
+ *     This value should be set to NV0080_CTRL_HOST_CAPS_TBL_SIZE.
+ *   capsTbl
+ *     This parameter specifies a pointer to the client's caps table buffer
+ *     into which the host caps bits will be transferred by the RM.
+ *     The caps table is an array of unsigned bytes.
+ *
+ * Possible status values returned are:
+ *   NV_OK
+ *   NV_ERR_INVALID_PARAM_STRUCT
+ *   NV_ERR_INVALID_ARGUMENT
+ *   NV_ERR_INVALID_POINTER
