The GIF sends textures and geometry to the GS. It takes data from three different PATHs: - PATH1: VU1 via XGKICK instruction. Highest priority. - PATH2: VIF1 via DIRECT/DIRECTHL. Medium priority. - PATH3: GIF DMAC channel (channel 2). Lowest priority. Only one PATH may run at a time. Under normal conditions, when one PATH stops, the highest priority queued PATH will begin transfer.
