The parameter list and return type for the member function in the derived class must match those of the member function in the base class, otherwise the function in the derived class will hide the function in the base class and no polymorphic behaviour will occur.

On the call to MSHR::handleSnoop these snoops were treated as if a response will be sent, as the MSHR was pendingModified. Consequently, a copy of the packet was created and added to the MSHR targets. However, an preceeding target to the same MSHR, originally from a CPU, was serviced before the snoop, and caused the block to be invalidated. This happens for ReadExReq and UpgradeReq. Note that the original snoop will receive a response, just not from the cache in question, but instead from the cache upstream that issued the ReadExReq or UpgradeReq.

Thus, the warm-up and cool-down variables should be globally visible to any Ruby components participating in either process. Make these variables static members and track the warm-up and cool-down processes as appropriate. This patch also has two side benefits: 1) It removes references to the RubySystem g_system_ptr, which are problematic for allowing multiple RubySystem instances in a single simulation. Warmup and cooldown variables being static (global) reduces the need for instance-specific dereferences through the RubySystem. 2) From the AbstractController, it removes local RubySystem pointers, which are used inconsistently with other uses of the RubySystem: 11 other uses reference the RubySystem with the g_system_ptr. Only sequencers have local pointers. |
