Gabe Black b64d0bdeda X86: Fix condition code setting for signed multiplies with negative results. 2009-08-05 03:07:01 -07:00
Gabe Black 2914a8eb16 X86: Make the check for negative operands for sign multiply more direct. 2009-08-05 03:06:37 -07:00
Gabe Black e2e0ae576a X86: Make sure immediate values are truncated properly. 
Register values will be "picked" which will assure they don't have junk beyond
the part we're using. Immediate values don't go through a similar process, so
we should truncate them explicitly.

Gabe Black 2f34a7eaeb X86: Tell the function that sends int messages who to send to instead of figuring it out itself. 2009-04-26 02:09:27 -07:00
Gabe Black 88ab4bb257 X86: Make the local APICs register themselves with the IO APIC. 
This is a hack so that the IO APIC can figure out information about the local
APICs. The local APICs still have no way to find out about each other.
Ideally, when the local APICs update state that's relevant to somebody else,
they'd send an update to everyone. Without being able to do a broadcast, that
would still require knowing who else there is to notify. Other broadcasts are
implemented using assumptions that may not always be true.
 2009-04-26 02:09:13 -07:00
Gabe Black c5e2cf841d X86: Record the initial APIC ID which identifies an APIC in M5. 
The ID as exposed to software can be changed. Tracking those changes in M5
would be cumbersome, especially since there's no guarantee the IDs will remain
unique.

Steve Reinhardt 52b6764f31 syscall: Resolve conflicts between m5threads and Gabe's recent SE changes. 2009-04-21 08:17:36 -07:00
Daniel Sanchez b0e9654f86 Commit m5threads package. 
This patch adds limited multithreading support in syscall-emulation
mode, by using the clone system call.  The clone system call works
for Alpha, SPARC and x86, and multithreaded applications run
correctly in Alpha and SPARC.

Gabe Black d90456a486 X86: Implement the stul microop. 
This microop does a store and unlocks the requested address. The RISC86
microop ISA doesn't seem to have an equivalent to this, so I'm guessing that
the store following an ldstl is automatically unlocking. We don't do it this
way for performance reasons since the behavior is the same.

Gabe Black d2554ff030 X86: Implement the ldstl microop. 
This microop does a load, checks that a store would succeed, and locks the
requested address.

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.

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

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.

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 e06321091d eventq: convert all usage of events to use the new API.

necessary for making the steps towards a parallelized m5.

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.

Nathan Binkert 8ea5176b7f arch: TheISA shouldn't really ever be used in the arch directory. 
We should always refer to the specific ISA in that arch directory.
This is especially necessary if we're ever going to make it to the
point where we actually have heterogeneous systems.
