"The following patches implement a more generalized infrastructure (than latency.c) for connecting drivers and subsystem's that could implement power performance optimizations with the data needed to implement such policies," began Mark Gross, describing his Quality of Service power management patchset. He added, "these patches are following up on the discussions and presentations at the power management summit last summer." Mark continued:

"The idea is that from an abstract point of view how much to throttle hardware can be expressed as a function of QoS types of parameters; Latency, throughput, and idle time outs.

"The qos_parameter patch is intended to put into place the registration and notification infrastructure for enabling QoS based policy choices by drivers, where constraints on throttling are communicated through the qos_params module."
