2018-09-17mem: Implement QoS Proportional Fair policyGiacomo 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>

2018-09-12cpu: Replace the fastmem with a new CPU modelAndreas Sandberg
The AtomicSimpleCPU used to be able to access memory directly to speed up simulation if no caches are used. This is fine as long as no switching between CPU models is required. In order to switch to a new CPU model that requires caches, we currently need to checkpoint the system and restore it into a new configuration. The new 'atomic_noncaching' memory mode provides a solution that avoids this issue since caches are bypassed in this mode. This changeset removes the old fastmem option from the AtomicSimpleCPU and introduces a new CPU, NonCachingSimpleCPU, which derives from the AtomicSimpleCPU. The NonCachingSimpleCPU uses the same mechanism as the AtomicSimpleCPU used to use when accessing memory in when fastmem was enabled. This changeset also introduces a new switcheroo test that tests switching between a NonCachingSimpleCPU and a TimingSimpleCPU with caches.

2018-09-11net: Fix a bug when receiving fragamented packetsPin-Yen Lin
In the previous implementation, the function EtherTap::recvReal will only read one packet when received some ``interrupt'' (explicitly, when async_IO set to true). When someone tries to send a large message to the simulated device, the message will be divided to several packets due to packet fragmentation. In this situation recvReal will only read one packet and left the other packets in the buffer. This significantly increases the networking latency. So before reading from socket, I change the socket into non-blocking mode and keep reading from it until there's no packet left.

2018-09-10base: Fix isSubset() for addr ranges with interleavingNikos Nikoleris
This change extends isSubset() which checks whether the range is a subset of an input range to support address ranges with interleaving and hashing.

2018-09-10dev-arm: Make GenericTimer use standard ArmInterruptPinGiacomo Travaglini
This patch is deleting the custom ArchTimer::Interrupt implementation in favour of the standard ArmInterruptPin.

2018-09-10dev-arm: Factory SimObject for generating ArmInterruptPinGiacomo Travaglini
With this patch the python ArmInterruptPin SimObject matches to the C++ ArmInterruptPinGen. The latter is in charge of generating the ArmInterruptPin (which is not a SimObject anymore). This is meant to ease the generation of ArmInterruptPins: by not being SimObjects we are not forced to instantiate them in the configuration script; we can generate them dynamically instead throughout simulation.

2018-09-10arm: Add support for tracking TCs in ISA devicesAndreas Sandberg
ISA devices typically need to keep track of the thread context they are associated with. Among other things, this is required for interrupt delivery. Add a BaseISADevice:setThreadContext() method to wire such models to the right thread context.
