2014-08-28mem: adding architectural page table support for SE modeAlexandru
This patch enables the use of page tables that are stored in system memory and respect x86 specification, in SE mode. It defines an architectural page table for x86 as a MultiLevelPageTable class and puts a placeholder class for other ISAs page tables, giving the possibility for future implementation.
2013-02-19scons: Add warning for overloaded virtual functionsAndreas Hansson
A derived function with a different signature than a base class function will result in the base class function of the same name being hidden. 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. This patch addresses these warnings by ensuring a unique function name to avoid (unintentionally) hiding any functions.

2010-08-17sim: revamp unserialization procedureSteve Reinhardt
Replace direct call to unserialize() on each SimObject with a pair of calls for better control over initialization in both ckpt and non-ckpt cases. If restoring from a checkpoint, loadState(ckpt) is called on each SimObject. The default implementation simply calls unserialize() if there is a corresponding checkpoint section, so we get backward compatibility for existing objects. However, objects can override loadState() to get other behaviors, e.g., doing other programmed initializations after unserialize(), or complaining if no checkpoint section is found. (Note that the default warning for a missing checkpoint section is now gone.) If not restoring from a checkpoint, we call the new initState() method on each SimObject instead. This provides a hook for state initializations that are only required when *not* restoring from a checkpoint. Given this new framework, do some cleanup of LiveProcess subclasses and X86System, which were (in some cases) emulating initState() behavior in startup via a local flag or (in other cases) erroneously doing initializations in startup() that clobbered state loaded earlier by unserialize().
2009-10-30Syscalls: Make system calls access arguments like a stack, not an array.Gabe Black
When accessing arguments for a syscall, the position of an argument depends on the policies of the ISA, how much space preceding arguments took up, and the "alignment" of the index for this particular argument into the number of possible storate locations. This change adjusts getSyscallArg to take its index parameter by reference instead of value and to adjust it to point to the possible location of the next argument on the stack, basically just after the current one. This way, the rules for the new argument can be applied locally without knowing about other arguments since those have already been taken into account implicitly. All system calls have also been changed to reflect the new interface. In a number of cases this made the implementation clearer since it encourages arguments to be collected in one place in order and then used as necessary later, as opposed to scattering them throughout the function or using them in place in long expressions. It also discourages using getSyscallArg over and over to retrieve the same value when a temporary would do the job.
2009-10-27POWER: Add support for the Power ISATimothy M. Jones
This adds support for the 32-bit, big endian Power ISA. This supports both integer and floating point instructions based on the Power ISA Book I v2.06.
