Richard Strong 81180a3bf0 This fix addresses an ill formed if statement that fails
to compile. The fix was the simple addition of another set
of parenthesis to ensure the correct condition resolution.

Gabe Black 7a4d75bae3 CPU: Refactor read/write in the simple timing CPU. 2008-11-13 23:30:37 -08:00
Clint Smullen 1adfe5c7f3 O3CPU: Make the instcount debugging stuff per-cpu.
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

Lisa Hsu 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.
2008-11-05 15:30:49 -05:00
Lisa Hsu dd99ff23c6 get rid of all instances of readTid() and getThreadNum(). Unify and eliminate
redundancies with threadId() as their replacement.
2008-11-04 11:35:42 -05:00
Lisa Hsu 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.
2008-11-02 21:57:07 -05:00
Lisa Hsu 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.
2008-11-02 21:57:06 -05:00
Lisa Hsu 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.

Clint Smullen 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.

comments.

Nathan Binkert 9836d81c2b style: Use the correct m5 style for things relating to interrupts. 2008-10-21 07:12:53 -07:00
Ali Saidi 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.

Nathan Binkert 94b08bed07 SimObjects: Clean up handling of C++ namespaces.
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.

Nathan Binkert 80d9be86e6 gcc: Add extra parens to quell warnings.
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.

Kevin Lim b784903207 O3CPU: Fix thread writeback logic.
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.

Kevin Lim 712a8ee700 O3CPU: Add a hack to ensure that nextPC is set correctly after syscalls.
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.

Nathan Binkert 6efb930e19 gcc: Version 4.3 is pretty anal about shadowing types, placate it.
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.

Gabe Black 3633a916c2 CPU: Get rid of two more duplicated CPU params. 2008-08-19 21:59:09 -07:00
Richard Strong 8d018aef0f Changed BaseCPU::ProfileEvent's interval member to be of type Tick. This was 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.

Nathan Binkert ee62a0fec8 params: Convert the CPU objects to use the auto generated param structs.
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.

Nathan Binkert 50ef39af82 sockets: Add a function to disable all listening sockets.
When invoking several copies of m5 on the same machine at the same
time, there can be a race for TCP ports for the terminal connections
or remote gdb.  Expose a function to disable those ports, and have the
regression scripts disable them.  There are some SimObjects that have
no other function than to be used with ports (NativeTrace and
EtherTap), so they will panic if the ports are disabled.
