#include <nitro/gx/gx_load.h>
void GX_LoadTex(const void *pSrc, u32 destSlotAddr, u32 szByte);
pSrc | Pointer to transfer origin |
destSlotAddr | Address in transfer destination texture image slot |
szByte | Transfer size (in bytes) |
None.
This function uses DMA to transfer texture images to the texture image slot. The transfer destination address (in the texture image slot) can be specified. The DMA channel that is used is GX_DMAID
(defined in gxcommon.h
). Both destSlotAddr
and szByte
must be 4-byte aligned. Call between GX_BeginLoadTex
and GX_EndLoadTex
.
Notes: Because the DMA transfer is carried out internally, the transfer source data must be flushed to the main memory using a function such as DC_FlushRange
prior to the process. If the regions for transfer source and transfer destination overlap, the operation result is undefined. Do not call GX_SetBankForTex
, GX_ResetBankForTex
, or GX_DisableBankForTex
between GX_BeginLoadTex
and GX_EndLoadTex
.
GX_BeginLoadTex, GX_EndLoadTex
