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

+ * @file nvdeprecated.h
+ *
+ * @brief Deprecation in the NVIDIA SDK
+ *
+ * Why deprecate:
+ *     Code is deprecated when you want to remove a feature entirely, but cannot
+ *     do so immediately, nor in a single step, due to a requirement to remain
+ *     backward compatible (keep older clients working).
+ *
+ * Backwards compatibility:
+ *     Deprecated symbols and features may be supported for an unknown amount of
+ *     time. "Deprecated" means that we want that time interval to be small, but
+ *     that may not be under our control.
+ *
+ *     This file provides the following ways to support deprecated features:
+ *
+ *     1) Defining NV_STRICT_SDK before including a SDK headers. This will
+ *        remove *all* deprecated APIs from the NV SDK, for example:
+ *
+ *        #define NV_STRICT_SDK
+ *        #include "sdk/foo.h"
+ *
+ *     2) Defining the per-feature compatibility setting before including the
+ *        SDK, for example:
+ *
+ *        #define NV_DEPRECATED_NVOS_STATUS   0   // enable compatibility mode
+ *        #include "sdk/foo.h"
+ *
+ * How to deprecate a feature in the SDK:
+ *
+ *    1) Define the deprecated feature in this file. Often, you'll want to
+ *       start with SDK compatibility enabled by default, for example:
+ *
+ *       #ifndef NV_DEPRECATED_FEATURE_NAME
+ *       #define NV_DEPRECATED_FEATURE_NAME 0
+ *       #endif
+ *
+ *    2) Wrap SDK definitions with compatibility #ifdefs:
+ *
+ *       #if NV_DEPRECATED_COMPAT(FEATURE_NAME)
+ *           ...legacy definitions...
+ *       #endif
+ *
+ *    3) In the API implementation, consider stubbing or wrapping the new API.
+ *
+ *    4) Update older clients: file bugs to track this effort. Bug numbers
+ *       should be placed in comments near the deprecated features that RM is
+ *       supporting. That way, people reading the code can easily find the
+ *       bug(s) that show the status of completely removing the deprecated
+ *       feature.
+ *
+ *    5) Once all the client (calling) code has been upgraded, change the
+ *       macro to "compatibility off". This is a little more cautious and
+ *       conservative than jumping directly to step (6), because it allows you
+ *       to recover from a test failure (remember, there are extended, offline
+ *       tests that are not, unfortunately, run in DVS, nor per-CL checkin)
+ *       with a tiny change in code.
+ *
+ *    6) Once the code base has migrated, remove all definitions from the SDK.
