2008-10-20O3CPU: Undo Gabe's changes to remove hwrei and simpalcheck from O3 CPU. ↵Ali Saidi
Removing hwrei causes the instruction after the hwrei to be fetched before the ITB/DTB_CM register is updated in a call pal call sys and thus the translation fails because the user is attempting to access a super page address. Minimally, it seems as though some sort of fetch stall or refetch after a hwrei is required. I think this works currently because the hwrei uses the exec context interface, and the o3 stalls when that occurs. Additionally, these changes don't update the LOCK register and probably break ll/sc. Both o3 changes were removed since a great deal of manual patching would be required to only remove the hwrei change.

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.
2008-09-29alpha: Need to include cstring so that g++ 4.3 works.Nathan Binkert
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.
2008-09-27style: Make a style pass over the whole arch/alpha directory.Nathan Binkert
2008-09-27alpha: Clean up namespace usage.Nathan Binkert
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.
2008-09-27alpha: Get rid fo the namespace called EV5.Nathan Binkert
We're never going to do an alpha platform other than the one we've got.

2008-08-13Return an UnimpFault for an ITB translation of an uncachable address. We ↵Ali Saidi
don't support fetching from uncached addresses in Alpha and it means that a speculative fetch can clobber device registers.
2008-07-23syscalls: Add a bunch of missing system calls.Michael Adler
readlink, umask, truncate, ftruncate, mkdir, and getcwd.
2008-07-11m5ops: clean up the m5ops stuff.Nathan Binkert
- insert warnings for deprecated m5ops - reserve opcodes for Ali's stuff - remove code for stuff that has been deprecated forever - simplify m5op_alpha
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.
