None.
This function uses DMA to transfer texture images to VRAM banks that can be allocated to texture image slots. The transfer destination address (in the texture image slot) can be specified. The DMA channel to use here is GX_DMAID (defined in gxcommon.h). Both destSlotAddr and szByte must be 4-byte aligned.
Notes: Because the DMA transfer is carried out internally, the transfer source data must be written to main memory in advance using a function such as DC_FlushRange.
If the regions for transfer source and transfer destination overlap, the operation result is undefined. The VRAM bank specified by tex must be mapped in LCDC space.
