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

+ * NV90CC_CTRL_CMD_HWPM_RESERVE
+ *
+ * This command attempts to reserve the perfmon for use by the calling client.
+ * If this object was allocated as a child of a subdevice, then the
+ * reservation will be global among all contexts on that subdevice. If this
+ * object was allocated as a child of a channel group or a channel, then the
+ * reservation will only be for the hardware context of that channel group or
+ * channel.
+ *
+ * If the global reservation is held on a subdevice by another client, then
+ * this command will fail, regardless of the parent class.
+ *
+ * If one or more per-context reservations are held by other clients, then
+ * this command will fail if the parent object is a subdevice or another
+ * client already holds the perfmon reservation for the parent context.
+ *
+ * This command will return NV_ERR_STATE_IN_USE for all of the failure
+ * cases described above. A return status of NV_OK guarantees
+ * that the client holds the perfmon reservation of the appropriate scope.
+ *
+ * This command does not take any parameters.
+ *
+ * Possible status values returned are:
+ *    NV_OK
+ *    NV_ERR_STATE_IN_USE

+ * NV90CC_CTRL_CMD_HWPM_GET_RESERVATION_INFO
+ *
+ * This command returns information about any outstanding perfmon
+ * reservations. If this object was allocated as a child of a subdevice, then
+ * this command will return information about all reservations on the
+ * subdevice (global or per-context). If this object was allocated as a child
+ * of a channel group or channel, then this command will only return
+ * information about the per-context reservation for that context or the
+ * global reservation, if one exists.
+ *
+ *   reservationCount
+ *     This parameter returns the number of outstanding perfmon reservations
+ *     in the applicable scope. If the value of the bGlobal parameter is
+ *     NV_TRUE, then this parameter will have a value of 1. If this object was
+ *     allocated as a child of a channel group or channel, then this parameter
+ *     will have a value of either 0 or 1. If this object was allocated as a
+ *     child of a subdevice and the bGlobal parameter is NV_FALSE, then this
+ *     parameter will return the number of per-context reservations on the
+ *     subdevice.
+ *   pid
+ *     This parameter returns the PID of a process that holds a reservation in
+ *     the applicable scope. If the value of the bGlobal parameter is NV_TRUE,
+ *     then this parameter will be the PID of the process holding the global
+ *     perfmon reservation on the subdevice. Otherwise, if the value of
+ *     reservationCount is greater than 0, the value of this parameter will be
+ *     the PID of one of the process that holds the per-context lock in the
+ *     applicable scope. If the value of the reservationCount parameter is 0,
+ *     the value of this parameter is undefined.
+ *   bGlobal
+ *     This parameter returns whether the outstanding perfmon reservation held
+ *     by any client is global or per-context. If the value of this parameter
+ *     is NV_TRUE, then the value of the reservationCount parameter should be 1
+ *     and the value of the pid parameter should be the pid of the process
+ *     that holds the global perfmon reservation. The value of this parameter
+ *     will be NV_FALSE when there is no global perfmon reservation.
+ *
+ * Possible status values returned are:
+ *    NV_OK
+ *    NV_ERR_INVALID_ARGUMENT
