I learn from "pm_qos_interface.txt" that cpu_dma_latency for each process. I write test program to write value and read it, the value is strange. for example, writes 0x20000000 prints 80485e9. If I don't write any value, just read, it prints b80db5. The "pm_qos_interface.txt" gives not much info.
If the qos cpu_dma_latency is not clear, Then how can menu governor choose it as a right value ?? If sth wrong, please correct me. Thanks.
