Hello,
Sorry to jump in this late, but, I've got a question in choosing QoS
value from the list with pm_qos_get_value function and pm_qos_type.
For QoS objects such as network throughput, wouldn't "PM_QOS_ADD" be
more appropriate than PM_QOS_MAX?
If A is requesting 10MB/s on NIC-X and B is requesting 5MB/s on NIC-X,
I guess PM QOS should say NIC-X that it needs to provide 15MB/s, not
10MB/s. Or, are we assuming that A and B will never put streams at the
same time?
Thanks,
MyungJoo
