=== NVGPU_IOCTL_CHANNEL_SET_NVMAP_FD ===
Binds a nvmap object to this channel. Identical to Linux driver.
  struct {
    u32 __nvmap_fd;    // in
  };
=== NVGPU_IOCTL_CHANNEL_ALLOC_GPFIFO ===
Allocates gpfifo entries. Identical to Linux driver.
  struct {
    u32 __num_entries;    // in
    u32 __flags;          // in
  };
=== NVGPU_IOCTL_CHANNEL_SUBMIT_GPFIFO ===
Submits a gpfifo object. Modified to take inline fence objects instead of a pointer.
  struct fence {
    u32 __id;
    u32 __value;
  };
  struct {
    u64 __gpfifo;              // in (pointer to gpfifo fence structs; ignored)
    u32 __num_entries;        // in (number of fence objects being submitted)
    u32 __flags;              // in
    struct fence __fence_out;  // out (returned new fence object for others to wait on)
    struct fence __fence;      // in (fence objects; depends on __num_entries)
    ...
  };
=== NVGPU_IOCTL_CHANNEL_ALLOC_OBJ_CTX ===
Allocates a graphics context object. Modified to ignore object's ID.
  struct {
    u32 __class_num;    // in (0xB197=2d, 0xB1C0=compute, 0xA140=kepler, 0xB0B5=DMA, 0xB06F=channel_gpfifo)

=== NVGPU_IOCTL_CHANNEL_SET_ERROR_NOTIFIER ===
Initializes the error notifier for this channel. Identical to Linux driver.
  struct {
    u64 __offset;    // in

=== NVGPU_IOCTL_CHANNEL_OPEN ===
Opens the current channel. Unused and takes an unknown argument.
  struct {
    u32 __unk;    // in (only accepts 0x32, 0x64 or 0x96)
  };
=== NVGPU_IOCTL_CHANNEL_ENABLE ===
Enables the current channel. Identical to Linux driver.
=== NVGPU_IOCTL_CHANNEL_DISABLE ===
Disables the current channel. Identical to Linux driver.
=== NVGPU_IOCTL_CHANNEL_PREEMPT ===
Clears the FIFO pipe for this channel. Identical to Linux driver.
=== NVGPU_IOCTL_CHANNEL_FORCE_RESET ===
Forces the channel to reset. Identical to Linux driver.
=== NVGPU_IOCTL_CHANNEL_EVENTS_CTRL ===
Controls event notifications. Modified to take an additional argument.
  struct {
    u32 __cmd;    // in (0=disable, 1=enable, 2=clear)
    u32 __unk;    // in (accepts 1 or 2)
  };

    ...
  };
=== NVGPU_IOCTL_CHANNEL_ALLOC_GPFIFO_EX2 ===
Allocates gpfifo entries with additional parameters and returns a fence. Exclusive to the Switch.
  struct fence {
