Dave Jiang 7ca68fa3c8 dmaengine: idxd: add configuration for concurrent batch descriptor processing
Add sysfs knob to allow control of the number of batch descriptors that can
be concurrently processed by an engine in the group as a fraction of the
Maximum Work Descriptors in Progress value specfied in ENGCAP register.
This control knob is part of toggle for QoS control.
