Function Documentation

◆ hipBindTextureToMipmappedArray()

hipError_t hipBindTextureToMipmappedArray	(	const textureReference *	tex,
		hipMipmappedArray_const_t	mipmappedArray,
		const hipChannelFormatDesc *	desc
	)

Binds a mipmapped array to a texture.

Parameters

[in]	tex	pointer to the texture reference to bind
[in]	mipmappedArray	memory mipmapped array on the device
[in]	desc	opointer to the channel format

Returns

hipSuccess, hipErrorInvalidValue

◆ hipCreateTextureObject()

hipError_t hipCreateTextureObject	(	hipTextureObject_t *	pTexObject,
		const hipResourceDesc *	pResDesc,
		const hipTextureDesc *	pTexDesc,

	)

Creates a texture object.

Parameters

[out]	pTexObject	pointer to the texture object to create
[in]	pResDesc	pointer to resource descriptor

Returns

hipSuccess, hipErrorInvalidValue, hipErrorNotSupported, hipErrorOutOfMemory

Note

3D liner filter isn't supported on GFX90A boards, on which the API hipCreateTextureObject will return hipErrorNotSupported.
