dd6ea8797f scons: Require SCons version 0.98.1 
This allows me to clean things up so we are up to date with respect to
deprecated features.  There are many features scheduled for permanent failure
in scons 2.0 and 0.98.1 provides the most compatability for that.  It
also paves the way for some nice new features that I will add soon

f1430941cf This brings M5 closer to modernity - the kernel being advertised is newer so it won't die on binaries compiled with newer glibc's, and enables use of TLS-toolchain built binaries for ALPHA_SE by putting auxiliary vectors on the stack. There are some comments in the code to help. Finally, stats changes for ALPHA are from slight perturbations to the initial stack frame, all minimal diffs. 2008-12-05 12:09:29 -05:00

5711282f87 Fix a bunch of bugs I introduced when I changed the flags stuff for packets. 
I did some of the flags and assertions wrong. Thanks to Brad Beckmann
for pointing this out.  I should have run the opt regressions instead
of the fast. I also screwed up some of the logical functions in the Flags
class.

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.

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.

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

bit of a pain for those users who get the order of operations correct,
but it is likely to prevent bugs in certain cases.

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.

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.

a4a7a09e96 Remove delVirtPort() and make getVirtPort() only return cached version. 2008-07-01 10:25:07 -04:00
Ali Saidi
c5fbbf376a Change everything to use the cached virtPort rather than created their own each time. 
This appears to work, but I don't want to commit it until it gets tested a lot more.
I haven't deleted the functionality in this patch that will come later, but one question
is how to enforce encourage objects that call getVirtPort() to not cache the virtual port
since if the CPU changes out from under them it will be worse than useless. Perhaps a null
function like delVirtPort() is still useful in that case.
