dmaengine: ti: k3-udma: Try to use the highest TPL channels for MEM_TO_MEM When running memcpy test with big buffers: echo 800000 > /sys/module/dmatest/parameters/test_buf_size echo 2000 > /sys/module/dmatest/parameters/timeout echo 20 > /sys/module/dmatest/parameters/iterations echo 10 > /sys/module/dmatest/parameters/max_channels echo 1 > /sys/module/dmatest/parameters/run The throughput with normal channels is: dmatest: dma1chan2-copy0: summary 200 tests, 0 failures 87 iops 308840 KB/s (0) Using High Throughput channel with the same setup: dmatest: dma1chan2-copy0: summary 200 tests, 0 failures 295 iops 1206172 KB/s (0) The speed increase is about 4x.
