Types

type Buffer

type Buffer struct {
	NvMapHandle uint32
	Size        uintptr
	Alignment   uint32
	Kind        uint8
}

func CreateBuffer

func CreateBuffer(addr unsafe.Pointer, size uintptr, heapMask, alignment uint32, kind nv.Kind) (*Buffer, error)

CreateBuffer creates a buffer in GPU equivalent to nvMapCreate on libnx

func InitializeFromId

func InitializeFromId(id uint32) (*Buffer, error)

func (*Buffer) Destroy

func (b *Buffer) Destroy() (refCount uint32, flags uint32, err error)

func (*Buffer) GetID

func (b *Buffer) GetID() (id uint32, err error)

type Fence

type Fence struct {
	SyncptId    uint32
	SyncptValue uint32
}

func (*Fence) Wait

func (g *Fence) Wait(timeout uint32) error
