2012-04-14X86: Use the AddrTrie class to implement the TLB.Gabe Black
This change also adjusts the TlbEntry class so that it stores the number of address bits wide a page is rather than its size in bytes. In other words, instead of storing 4K for a 4K page, it stores 12. 12 is easy to turn into 4K, but it's a little harder going the other way.
2012-03-30MEM: Introduce the master/slave port sub-classes in C++William Wang
This patch introduces the notion of a master and slave port in the C++ code, thus bringing the previous classification from the Python classes into the corresponding simulation objects and memory objects. The patch enables us to classify behaviours into the two bins and add assumptions and enfore compliance, also simplifying the two interfaces. As a starting point, isSnooping is confined to a master port, and getAddrRanges to slave ports. More of these specilisations are to come in later patches. The getPort function is not getMasterPort and getSlavePort, and returns a port reference rather than a pointer as NULL would never be a valid return value. The default implementation of these two functions is placed in MemObject, and calls fatal. The one drawback with this specific patch is that it requires some code duplication, e.g. QueuedPort becomes QueuedMasterPort and QueuedSlavePort, and BusPort becomes BusMasterPort and BusSlavePort (avoiding multiple inheritance). With the later introduction of the port interfaces, moving the functionality outside the port itself, a lot of the duplicated code will disappear again.
2012-03-09CheckerCPU: Add function stubs to non-ARM ISA source to compile with CheckerCPUGeoffrey Blake
Making the CheckerCPU a runtime time option requires the code to be compatible with ISAs other than ARM. This patch adds the appropriate function stubs to allow compilation.
2012-03-01x86: Fix x86 TLB and WalkerNilay Vaish
This patch adds a function to X86 tlb that returns the walker port. This port is required for correctly connecting the walker ports for the cpu just switched in

2011-02-06x86: Timing support for pagetable walkerJoel Hestness
Move page table walker state to its own object type, and make the walker instantiate state for each outstanding walk. By storing the states in a queue, the walker is able to handle multiple outstanding timing requests. Note that functional walks use separate state elements.
2011-02-03Fault: Rename sim/fault.hh to fault_fwd.hh to distinguish it from faults.hh.Gabe Black
--HG-- rename : src/sim/fault.hh => src/sim/fault_fwd.hh
2010-09-13Faults: Pass the StaticInst involved, if any, to a Fault's invoke method.Gabe Black
Also move the "Fault" reference counted pointer type into a separate file, sim/fault.hh. It would be better to name this less similarly to sim/faults.hh to reduce confusion, but fault.hh matches the name of the type. We could change Fault to FaultPtr to match other pointer types, and then changing the name of the file would make more sense.
2010-08-23X86: Create a directory for files that define register indexes.Gabe Black
This is to help tidy up arch/x86.
