=== NVGPU_GPU_IOCTL_WAIT_FOR_PAUSE ===
Waits until all valid warps on the GPU SM are paused and returns their current state.
struct {
__in u64 pwarpstate;
};
[6.1.0+] This command was modified to return inline data instead of using a pointer.
struct {

__out u64 sm1_paused_warps;
};
=== NVGPU_GPU_IOCTL_GET_TPC_EXCEPTION_EN_STATUS ===
Returns a mask value describing all active TPC exceptions. Identical to Linux driver.
struct {

};
=== NVGPU_GPU_IOCTL_NUM_VSMS ===
Returns the number of GPU SM units present. Identical to Linux driver.
struct {
__out u32 num_vsms;
__out u32 reserved;
};
=== NVGPU_GPU_IOCTL_VSMS_MAPPING ===
Returns mapping information on each GPU SM unit. Modified to return inline data instead of using a pointer.
struct {
__out u8 sm0_gpc_index;
__out u8 sm0_tpc_index;
__out u8 sm1_gpc_index;
__out u8 sm1_tpc_index;

};
=== NVGPU_GPU_IOCTL_SET_CG_CONTROLS ===
Sets the clock gate control value.
struct {
__in u32 cg_mask;

};
=== NVGPU_GPU_IOCTL_SET_PG_CONTROLS ===
Sets the power gate control value.
struct {
__in u32 pg_mask;
__in u32 pg_value;
};
=== NVGPU_GPU_IOCTL_GET_PG_CONTROLS ===
Returns the power gate control value.
struct {
__in u32 pg_mask;
__out u32 pg_value;
