Nathan Binkert 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

Nathan Binkert e141cb7441 flags: Change naming of functions to be clearer 2008-12-06 14:18:18 -08:00
Lisa Hsu 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
Lisa Hsu e2c7618e50 This patch pulls out the auxiliary vector struct from individual ISA 
LiveProcesses to the base LiveProcess definition so anyone can use them.

Steve Reinhardt 4514f565e3 syscalls: fix latent brk/obreak bug. 
Bogus calls to ChunkGenerator with negative size were triggering
a new assertion that was added there.
Also did a little renaming and cleanup in the process.
 2008-11-15 09:30:10 -08:00
Nathan Binkert 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.

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.

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 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.

point where we actually have heterogeneous systems.

A whole bunch of stuff has been converted to use the new params stuff, but

more stylish. Most of the work was done by Gabe, I just cleaned stuff up
a bit more at the end.
