upload_back_buffer()

MAYAFLUX_API void MayaFlux::Buffers::upload_back_buffer	(	const VKBufferResources::GenerationSlot &	slot,
		const void *	data,
		size_t	size,
		std::shared_ptr< VKBuffer > &	staging
	)

Upload host memory into a raw back_buffers slot.

Parameters

slot	Destination slot, typically from VKBuffer::get_back_buffer().
data	Source pointer, at least size bytes.
size	Byte count to copy.
staging	Persistent staging buffer for device-local slots. Ignored, and may be null, when slot.mapped_ptr is already valid.

Writes through slot.mapped_ptr directly when present (host-visible slot, no transfer). Otherwise copies into staging and records a fenced device-to-device copy into slot.buffer, mirroring download_back_buffer with the direction reversed.

    auto handle = upload_back_buffer_async(slot, data, size, staging);
