2013-06-03arch: Create a method to finalize physical addressesAndreas Sandberg
in the TLB Some architectures (currently only x86) require some fixing-up of physical addresses after a normal address translation. This is usually to remap devices such as the APIC, but could be used for other memory mapped devices as well. When running the CPU in a using hardware virtualization, we still need to do these address fix-ups before inserting the request into the memory system. This patch moves this patch allows that code to be used by such CPUs without doing full address translations.
2013-01-07arch: Add support for invalidating TLBs when drainingAndreas Sandberg
This patch adds support for the memInvalidate() drain method. TLB flushing is requested by calling the virtual flushAll() method on the TLB. Note: This patch renames invalidateAll() to flushAll() on x86 and SPARC to make the interface consistent across all supported architectures.
2012-10-15Port: Add protocol-agnostic ports in the port hierarchyAndreas Hansson
This patch adds an additional level of ports in the inheritance hierarchy, separating out the protocol-specific and protocl-agnostic parts. All the functionality related to the binding of ports is now confined to use BaseMaster/BaseSlavePorts, and all the protocol-specific parts stay in the Master/SlavePort. In the future it will be possible to add other protocol-specific implementations. The functions used in the binding of ports, i.e. getMaster/SlavePort now use the base classes, and the index parameter is updated to use the PortID typedef with the symbolic InvalidPortID as the default.
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.
