Description

The Graphics Processor (GP) can count many internal events that give detailed information on performance. This function clears the memory request counters. The counters can be read by calling GXReadMemMetric. Since the counters are cleared by writing CPU-accessible registers, this function should not be used in a display list.

u32 cp_req, tc_req, cpu_rd_req, cpu_wr_req, dsp_req, io_req, vi_req, pe_req; u32 rf_req, fi_req; GXReadClearMetric(); // Draw Object(s)

// wait until object drawn GXSetDrawSync(0xbeef); while (0xbeef != GXReadDrawSync()) ; metric = GXReadMemMetric(&cp_req, &tc_req, &cpu_rd_req, &cpu_wr_req, &dsp_req, &io_req, &vi_req, &pe_req, &rf_req, &fi_req ); // returns request counter OSReport("Number command processor requests: %d\n", cp_req);
