2018-03-23learning_gem5: Add a simple config for MI_exampleJason Lowe-Power
Adds a new config script to configure the MI_example protocol. This script closely follows the script used for MSI, but instead supports the MI_example protocol. This script works with the simple_ruby runscript and can be included instead of msi_caches.

2018-03-22mem-cache: Split array indexing and replacement policies.Daniel R. Carvalho
Replacement policies (LRU, Random) are currently considered as array indexing methods, but have completely different functionalities: - Array indexers determine the possible locations for block allocation. This information is used to generate replacement candidates when conflicts happen. - Replacement policies determine which of the replacement candidates should be evicted to make room for new allocations. For this reason, they were split into different classes. Advantages: - Easier and more straightforward to implement other replacement policies (RRIP, LFU, ARC, ...) - Allow easier future implementation of cache organization schemes As now we can't assure the use of sets, the previous way to create a true LRU is not viable. Now a timestamp_bits parameter controls how many bits are dedicated for the timestamp, and a true LRU can be achieved through an infinite number of bits (although a few bits suffice in practice).

These functions were already being treated as psuedo objects and had properties assigned to them setting what their paths were. That's a bit unusual and made it less obvious what the code was doing, but also forced the "system" function to know what all the possible path searching functions were so that they'd have their "path" property initialized properly in a central location. This change introduces a PathSearcFunc class which encapsulates the mechanisms of the old code and makes it implicitly extensible so that other path searching functions which might look in other directories can be added in other places.

2017-07-05cpu: Added interface for vector reg fileRekai Gonzalez-Alberquilla
This patch adds some more functionality to the cpu model and the arch to interface with the vector register file. This change consists mainly of augmenting ThreadContexts and ExecContexts with calls to get/set full vectors, underlying microarchitectural elements or lanes. Those are meant to interface with the vector register file. All classes that implement this interface also get an appropriate implementation. This requires implementing the vector register file for the different models using the VecRegContainer class. This change set also updates the Result abstraction to contemplate the possibility of having a vector as result. The changes also affect how the remote_gdb connection works. There are some (nasty) side effects, such as the need to define dummy numPhysVecRegs parameter values for architectures that do not implement vector extensions.

2017-07-03config: Make ex5_*.py independent of old configsAndreas Sandberg
The ex5_LITTLE and ex5_big configs currently depend on Caches.py and O3_ARM_v7a.py. These aren't actual dependencies since all of the params from the caches and the old O3 model are overridden. This changeset updates the ex5 models to derive from the base SimObjects instead.

MemConfig currently assumes that all callers include the its full set of options in the command line parser. This is unnecessary and sometimes confusing. Make most of the options optional to avoid having to add all of them to example scripts.
