2008-11-02Add in Context IDs to the simulator. From now on, cpuId is almost never used,Lisa Hsu
the primary identifier for a hardware context should be contextId(). The concept of threads within a CPU remains, in the form of threadId() because sometimes you need to know which context within a cpu to manipulate.
2008-11-02Make it so that all thread contexts are registered with the System, even inLisa Hsu
SE. Process still keeps track of the tc's it owns, but registration occurs with the System, this eases the way for system-wide context Ids based on registration.
2008-11-02make BaseCPU the provider of _cpuId, and cpuId() instead of being scatteredLisa Hsu
across the subclasses. generally make it so that member data is _cpuId and accessor functions are cpuId(). The ID val comes from the python (default -1 if none provided), and if it is -1, the index of cpuList will be given. this has passed util/regress quick and se.py -n4 and fs.py -n4 as well as standard switch.
2008-10-21style: Use the correct m5 style for things relating to interrupts.Nathan Binkert
2008-10-12Get rid of old RegContext code.Gabe Black
2008-10-12CPU: Create a microcode ROM object in the CPU which is defined by the ISA.Gabe Black
2008-10-12Turn Interrupts objects into SimObjects. Also, move local APIC state into ↵Gabe Black
x86's Interrupts object.
2008-10-12CPU: Eliminate the get_vec function.Gabe Black
2008-10-10TLB: Make all tlbs derive from a common base class in both python and C++.Gabe Black
2008-10-10misc: remove #include <cassert> from misc.hh since not everyone needs it.Nathan Binkert
2008-10-09SimObjects: Clean up handling of C++ namespaces.Nathan Binkert
Make them easier to express by only having the cxx_type parameter which has the full namespace name, and drop the cxx_namespace thing. Add support for multiple levels of namespace.
2008-10-09eventq: convert all usage of events to use the new API.Nathan Binkert
For now, there is still a single global event queue, but this is necessary for making the steps towards a parallelized m5.
2008-09-27gcc: Add extra parens to quell warnings.Nathan Binkert
Even though we're not incorrect about operator precedence, let's add some parens in some particularly confusing places to placate GCC 4.3 so that we don't have to turn the warning off. Agreed that this is a bit of a pain for those users who get the order of operations correct, but it is likely to prevent bugs in certain cases.
2008-09-27arch: TheISA shouldn't really ever be used in the arch directory.Nathan Binkert
We should always refer to the specific ISA in that arch directory. This is especially necessary if we're ever going to make it to the point where we actually have heterogeneous systems.
2008-09-26When nesting if statements, use braces to avoid ambiguous else clauses.Nathan Binkert
2008-09-26style: bring this file into M5 style, use the new pte translate function.Nathan Binkert
2008-09-23sparc: Fix style, create a helper function for translation.Nathan Binkert
The translate function simplifies code and removes some compiler warnings in gcc 3.4
2008-09-10style: Remove non-leading tabs everywhere they shouldn't be. Developers ↵Ali Saidi
should configure their editors to not insert tabs

readlink, umask, truncate, ftruncate, mkdir, and getcwd.
2008-07-01Remove delVirtPort() and make getVirtPort() only return cached version.Ali Saidi
2008-07-01Change everything to use the cached virtPort rather than created their own ↵Ali Saidi
each time. This appears to work, but I don't want to commit it until it gets tested a lot more. I haven't deleted the functionality in this patch that will come later, but one question is how to enforce encourage objects that call getVirtPort() to not cache the virtual port since if the CPU changes out from under them it will be worse than useless. Perhaps a null function like delVirtPort() is still useful in that case.
