2018-12-04	base, sim: Add missing destructors	Nikos Nikoleris
	Derived classes with virtual functions need to define a virtual destructor or a protected destructor otherwise calling the base class destructor has undefined behavior. This change adds a virtual distructor in the base class.

2018-09-17	mem: Implement QoS Proportional Fair policy	Giacomo Travaglini
	Providing a configurable fair scheduling policy based on utilization; utilization is directly proportional to a score which is inversely proportional to the QoS priority. It is meant to avoid starvation of low priority packets. Users can tune the policy by adjusting the weight parameter (weight of the following formula) new_score = ((1.0 - weight) * old_score) + (weight * served_bytes) Change-Id: I7679e234b916c57ebed06cec0ff3cff3cf2aef22 Signed-off-by: Giacomo Travaglini <giacomo.travaglini@arm.com> Reviewed-on: https://gem5-review.googlesource.com/12359 Reviewed-by: Daniel Carvalho <odanrc@yahoo.com.br> Reviewed-by: Anthony Gutierrez <anthony.gutierrez@amd.com> Maintainer: Anthony Gutierrez <anthony.gutierrez@amd.com>
2018-09-07	mem: Implement base QoS Policies.	Giacomo Travaglini
	This patch implements a base fixed priority policy and an ideal turnaround policy for the QoS memory controller.

2018-09-07	mem: Add a QoS-aware Memory Controller type	Matteo Andreozzi
	This is the implementation of QoS algorithms support for gem5 memory objects. This change-list provides a framework for specifying QoS algorithm which can be used to prioritise service to specific masters in the memory controller. The QoS support implemented here is designed to be extendable so that new QoS algorithms can be easily plugged into the memory controller as "QoS Policies".
