63127cbf37 mem: Assert that requests have non-negative size. 
Would have saved me much debugging time if these
had been in there previously.

ddd179a418 Reference updates. Since split cache is gone, a lot of config.ini changes, and minor changes to stats that are likely due to the decoupling of insertions/evictions in the cache. 2008-11-06 11:11:42 -05:00

07969dbbf1 Right now a single thread cpu 1 could get assigned context Id != 1, depending 
on the order in which it's registered with the system.  To make them match,
here is a little change.

4ab52cb986 Change the findBlock(addr, lat) to accessBlock, which I think has better connotations for what is really happening and how it should be used. 2008-11-04 11:35:57 -05:00

dd99ff23c6 get rid of all instances of readTid() and getThreadNum(). Unify and eliminate 
redundancies with threadId() as their replacement.

d857faf073 Add in Context IDs to the simulator. From now on, cpuId is almost never used, 
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.

67fda02dda Make it so that all thread contexts are registered with the System, even in 
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.

c55a467a06 make BaseCPU the provider of _cpuId, and cpuId() instead of being scattered 
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.

95af120e60 CPU: The API change to EventWrapper did not get propagated to the entirety of TimingSimpleCPU. 
The constructor no-longer schedules an event at construction and the implict conversion between int and bool was allowing the old code to compile without warning.

cfa32d8de7 Checkpointing: createCountedDrain function, it was only returning an Event, which does not expose a setCount method to Python.

b760b99f4d O3CPU: Undo Gabe's changes to remove hwrei and simpalcheck from O3 CPU. 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.

ff2eea1ba3 eventq: revert code for unserializing events. 
Since I never implemented a proper solution, put it back to something that
at least works for now.  Once I add more event queues, I'll have to really
fix this though
