2010-07-22O3CPU: O3's tick event gets squashed when it is switched out. When repeatedlyTimothy M. Jones
switching between O3 and another CPU, O3's tick event might still be scheduled in the event queue (as squashed). Therefore, check for a squashed tick event as well as a non-scheduled event when taking over from another CPU and deal with it accordingly.

2009-07-08Registers: Add an ISA object which replaces the MiscRegFile.Gabe Black
This object encapsulates (or will eventually) the identity and characteristics of the ISA in the CPU.

2009-04-17o3, inorder: fix FS bug due to initializing ThreadState to Halted.Steve Reinhardt
For some reason o3 FS init() only called initCPU if the thread state was Suspended, which was no longer the case. There's no apparent reason to check, so I whacked the test completely rather than changing the check to Halted. The inorder init() was also updated to be symmetric, though the previous code was just a fancy no-op.
2009-04-15o3: fix {read,set}ArchFloatReg* functions.Steve Reinhardt
Register indices were not being calculated properly.
2009-04-15ThreadState: initialize status to Halted in constructor.Steve Reinhardt
This provides a common initial status for all threads independent of CPU model (unlike the prior situation where CPUs initialized threads to inconsistent states). This mostly matters for SE mode; in FS mode, ISA-specific startupCPU() methods generally handle boot-time initialization of thread contexts (since the right thing to do is ISA-dependent).

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.

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
2008-11-02Add 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.

2008-10-21style: 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.
2008-10-09O3: Generalize the O3 CPU object so it isn't split out by ISA.Gabe Black
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.
2008-08-11params: 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.

2007-03-23A couple of minor fixes.Kevin Lim
1. Set CPU ID in all modes for the O3 CPU. 2. Use nextCycle() function to prevent phase drift in O3 CPU. 3. Remove assertion in rename map that is no longer true. src/cpu/o3/alpha/cpu_builder.cc: Allow for CPU id in all modes, not just full system. Also include a parameter that was left out by accident. src/cpu/o3/alpha/cpu_impl.hh: Set the CPU ID properly. src/cpu/o3/cpu.cc: src/cpu/o3/cpu.hh: Use nextCycle() function so that the CPU does not get out of phase when starting up from quiesces. src/cpu/o3/rename_map.cc: Remove assertion that is no longer true. tests/configs/o3-timing.py: Set CPU's id to 0. --HG-- extra : convert_revision : 2b69c19adfce2adcc2d1939e89d702bd6674d5d5
2007-03-09Two fixes:Kevin Lim
1. Make sure connectMemPorts() only gets called when the CPU's peer gets changed. This is done by making setPeer() virtual, and overriding it in the CPU's ports. When it gets called on a CPU's port (dcache specifically), it calls the normal setPeer() function, and also connectMemPorts(). 2. Consolidate redundant code that handles switching in a CPU. src/cpu/base.cc: Move common code of switching over peers to base CPU. src/cpu/base.hh: Move common code of switching over peers to BaseCPU. src/cpu/o3/cpu.cc: Add in function that updates thread context's ports. Also use updated function to takeOverFrom() in BaseCPU. This gets rid of some repeated code. src/cpu/o3/cpu.hh: Include function to update thread context's memory ports. src/cpu/o3/lsq.hh: Add function to dcache port that will update the memory ports upon getting a new peer. Also include a function that will tell the CPU to update those memory ports. src/cpu/o3/lsq_impl.hh: Add function that will update the memory ports upon getting a new peer. src/cpu/simple/atomic.cc: src/cpu/simple/timing.cc: Add function that will update thread context's memory ports upon getting a new peer. Also use the new BaseCPU's take over from function. src/cpu/simple/atomic.hh: Add in function (and dcache port) that will allow the dcache to update memory ports when it gets assigned a new peer. src/cpu/simple/timing.hh: Add function that will update thread context's memory ports upon getting a new peer. src/mem/port.hh: Make setPeer virtual so that other classes can override it. --HG-- extra : convert_revision : 2050f1241dd2e83875d281cfc5ad5c6c8705fdaf
