[RFC/RFT][PATCH 0/5] PM / QoS: Introduce latency tolerance device PM QoS type

2014-01-17 Thread Rafael J. Wysocki
Hi All, On some platforms hardware may switch to an energy-saving mode on the fly on the basis of certain utilization metrics used by it. That usually is desirable from the energy conservation standpoint, but it generally causes latencies to increase which may adversely affect some operations.
