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.
2008-07-15Use ReadResp instead of LoadLockedResp for LoadLockedReq responses.Steve Reinhardt
2008-07-01Make the cached virtPort have a thread context so it can do everything that ↵Ali Saidi
a newly created one can.
2008-07-01After a checkpoint (and thus a stats reset), the ↵Ali Saidi
not_idle_fraction/notIdleFraction statistic is really wrong. The notIdleFraction statistic isn't updated when the statistics reset, probably because the cpu Status information was pulled into the atomic and timing cpus. This changeset pulls Status back into the BaseSimpleCPU object. Anyone care to comment on the odd naming of the Status instance? It shouldn't just be status because that is confusing with Port::Status, but _status seems a bit strage too.

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

2006-11-29Change the connecting of the physPort and virtPort to the memory object ↵Kevin Lim
below the CPU to happen every time activateContext is called. The overhead is probably a little higher than necessary, but allows these connections to properly be made when there are CPUs that are inactive until they are switched in. Right now this introduces a minor memory leak as old physPorts and virtPorts are not deleted when new ones are created. A flyspray task has been created for this issue. It can not be resolved until we determine how the bus will handle giving out ID's to functional ports that may be deleted. src/cpu/o3/cpu.cc: src/cpu/simple/atomic.cc: src/cpu/simple/timing.cc: Change the setup of the physPort and virtPort to instead happen every time the CPU has a context activated. This is a little high overhead, but keeps it working correctly when the CPU does not have a physical memory attached to it until it switches in (like the case of switch CPUs). src/cpu/o3/thread_context.hh: Change function from being called at init() to just being called whenever the memory ports need to be connected. src/cpu/o3/thread_context_impl.hh: Update this to not delete the port if it's the same as the virtPort. src/cpu/thread_context.hh: Change function from being called at init() to whenever the memory ports need to be connected. src/cpu/thread_state.cc: Instead of initializing the ports, simply connect them, deleting any old ports that might exist. This allows these functions to be called multiple times. src/cpu/thread_state.hh: Ports are no longer initialized, but rather connected at context activation time. --HG-- extra : convert_revision : e399ce5dfbd6ad658c953a7c9c7b69b89a70219e

2006-11-14Various fixes to delete packet and request a little better.Kevin Lim
src/cpu/simple/timing.cc: Various updates for deleting requests more properly. The major change is moving the deletion of the fetch request/packet to after the instruction has executed and completed. This should fix a few bugs because Ron's memory system didn't expect a call for a functional access while a timing access was being processed. --HG-- extra : convert_revision : c7cf114bb1ff3cdaa7b0a40ed4c5302dc9d3a522
