2009-01-24cpu: provide a wakeup mechanism that can be used to pull CPUs out of sleep.Nathan Binkert
Make interrupts use the new wakeup method, and pull all of the interrupt stuff into the cpu base class so that only the wakeup code needs to be updated. I tried to make wakeup, wakeCPU, and the various other mechanisms for waking and sleeping a little more sane, but I couldn't understand why the statistics were changing the way they were. Maybe we'll try again some day.

2009-01-19thread_context: move getSystemPtr so SE mode can get to it.Nathan Binkert
There was really no reason that it should be FS only.

2008-11-10O3CPU: Make the instcount debugging stuff per-cpu.Clint Smullen
This is to prevent the assertion from firing if you have a large multicore. Also make sure that it's not compiled in when NDEBUG is defined
2008-11-04get rid of all instances of readTid() and getThreadNum(). Unify and eliminateLisa Hsu
redundancies with threadId() as their replacement.
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 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.
2008-10-23s/cpu_id/cpuId in o3 (to be consistent and match style), also fix some typos inLisa Hsu
comments.
2008-10-21style: Use the correct m5 style for things relating to interrupts.Nathan Binkert
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.

2008-10-09eventq: 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.
2008-09-26O3CPU: Fix thread writeback logic.Kevin Lim
Fix the logic in the LSQ that determines if there are any stores to write back. In the commit stage, check for thread specific writebacks instead of just any writeback.
2008-09-26O3CPU: Add a hack to ensure that nextPC is set correctly after syscalls.Kevin Lim
Just check CPU's nextPC before and after syscall and if it changes, update this instruction's nextPC because the syscall must have changed the nextPC.
2008-09-22gcc: Version 4.3 is pretty anal about shadowing types, placate it.Nathan Binkert
In the future, it would be nice to put the O3CPU into its own namespace so that we don't end up hardcoding pointers to the global namespace.
2008-09-10style: Remove non-leading tabs everywhere they shouldn't be. Developers ↵Ali Saidi
should configure their editors to not insert tabs
2008-08-18Changed BaseCPU::ProfileEvent's interval member to be of type Tick. This was ↵Richard Strong
done to be consistent with its python type of a latency. In addition, the multiple definitions of profile in the different cpu models caused problems for intialization of the interval value. If a child class's profile value was defined, the parent BaseCPU::ProfileEvent interval field would be initialized with a garbage value. The fix was to remove the multiple redifitions of profile in the child CPU classes.
2008-08-11params: Convert the CPU objects to use the auto generated param structs.Nathan Binkert
A whole bunch of stuff has been converted to use the new params stuff, but the CPU wasn't one of them. While we're at it, make some things a bit more stylish. Most of the work was done by Gabe, I just cleaned stuff up a bit more at the end.

--HG-- extra : convert_revision : d811bf87d1a0bfc712942ecd3db1b48fc75257af
2008-01-14The reason is that the event is supposed to put the instructions ready to ↵Ke Meng
execute for next cycle. And the FUCompletion event has a lower priority than CPU tick event. It is called after the iew->tick() for current cycle has already been executed and the issueToExecuteQueue has already advanced this time. And assume the issueToExecuteLatency is 1, to catch up, the increasement should be made at access(-1) instead of access(0). Otherwise I found it could increase the actual op_latency of the instructions to execute by 1 cycle and potentially put the simulated CPU into a permanent idle state.
