2018-10-10mem-cache: Use set and way for ReplaceableEntryDaniel R. Carvalho
Replaceable entries belong to table-like structures, and therefore they should be indexable by combining a row and a column. These, using conventional cache nomenclature translate to sets and ways. Make these entries aware of their sets and ways. The idea is to make indexing policies usable by other table-like structures. In order to do so we move sets and ways to ReplaceableEntry, which will be the common base among table entries.

2018-10-10mem-cache: Create tags initialization functionDaniel R. Carvalho
Having the blocks initialized in the constructor makes it harder to apply inheritance in the tags classes.

2018-10-09systemc: Change how the scheduler orders processes.Gabe Black
The Accellera implementation looks like it does all the methods, then all the threads, and then loops back and tries again, and there are even comments in the code that suggests that. What it actually does, however, is runs all the methods, then runs a single thread if one is waiting, and then starts over. The effect is that the scheduler will run any methods first, then run threads until a method might have become ready, and then repeat. This will actually result in more mixing of threads and methods, more context switches, and worse performance, but it makes the regressions pass more.

2018-10-09systemc: Rework how delayed sensitivities are handled.Gabe Black
Make BindInfo into a more general purpose Port class which mirrors sc_module and Module, sc_object and Object, etc. This tracks multiple bindings internally, and also pending sensitivities. Keep a global list of ports which are added in reverse order to match Accellera, and which is iterated over to finalize binding and for phase callbacks. This is as opposed to doing it one module at a time, and is to better match Accellera's ordering for the regressions. Also the sensitivity classes are now built with factory functions, which gets around problems calling virtual functions from their constructors or forgetting to having to have extra boilerplate each place they're constructed. The port class also now finalizes port or event finder sensitivities when its binding is completed, unless it's already complete in which case it does so immediately.

2018-10-09systemc: Refactor sensitivities.Gabe Black
Dynamic and Static sensitivities used to be represented by the same classes, even though they're (almost) disjoint in how they worked. Also timeouts, which can be used alongside dynamic sensitivities, were handled by the sensitivities themselves. That meant that the sensitivity mechanism had to mix in more types of behaviors, increasing complexity. Also, the non-standard timed_out function Accellera includes is harder to implement if the path for timeouts and regular sensitivities are mixed together. This change splits up dynamic and static sensitivities and splits out timeouts. It also immitates the ordering Accellera uses when going through sensitivities for an event. Static sensitivities are triggered first in reverse order (why?), and then dynamic sensitivities are triggered in what amounts to reverse order. To delete a sensitivity which has been handled, it's swapped with the one in the last position, and then the vector is truncated to drop it at the end. This has the net effect of stirring the dynamic sensitivities, and isn't easily immitated using a different approach, even if other approaches would be more straightforward. Double check addSensitivity for event.hh Change-Id: I1e73dce386b95f68e9d6737deb8bed70ef717e0d Reviewed-on: https://gem5-review.googlesource.com/c/12805 Reviewed-by: Gabe Black <gabeblack@google.com> Maintainer: Gabe Black <gabeblack@google.com>
