=== 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)

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)

u64 __obj_id; // out (ignored; used for FREE_OBJ_CTX ioctl, which is not supported)
};
=== NVGPU_IOCTL_CHANNEL_SET_ERROR_NOTIFIER ===
Initializes the error notifier for this channel. Identical to Linux driver.
struct {
u64 __offset; // in
u64 __size; // in
u32 __mem; // in (nvmap object handle)
u32 __padding; // 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_GET_ERROR ===
Returns the current error notification caught by the error notifier. Exclusive to the Switch.
struct {
u64 __timestamp; // out (nanoseconds since Jan. 1, 1970)
u32 __info32; // out (error code)
u16 __info16; // out (additional error info)
u16 __status; // out (always 0xFFFF)

=== NVGPU_IOCTL_CHANNEL_SUBMIT_GPFIFO_EX ===
Submits a gpfifo object (async version). Exclusive to the Switch.
struct fence {
u32 __id;
u32 __value;
};
struct {
u64 __gpfifo; // in (pointer to gpfifo fence structs; ignored)
