1) Removing files from the ruby build left some unresovled
symbols. Those have been fixed.
2) Most of the dependencies on Simics data types and the simics
interface files have been removed.
3) Almost all mention of opal is gone.
4) Huge chunks of LogTM are now gone.
5) Handling 1-4 left ~hundreds of unresolved references, which were
fixed, yielding a snowball effect (and the massive size of this
delta).

I did the macro cleanup because I was worried that the SCons scanner
would get confused. This code will hopefully go away soon anyway.

We eventually plan to replace the m5 cache hierarchy with the GEMS
hierarchy, but for now we will make both live alongside eachother.

this was double scheduling itself (once in constructor and once in cpu code). also add support for stopping / starting
progress events through repeatEvent flag and also changing the interval of the progress event as well

Start by turning all of the *Source functions into classes
so we can do more calculations and more easily collect the data we need.
Add parameters to the new classes for indicating what sorts of flags the
objects should be compiled with so we can allow certain files to be compiled
without Werror for example.

Lowest priority interrupts are now delivered based on a rotating offset into
the list of potential recipients. There could be parasitic cases were a
processor gets picked on and ends up at that rotating offset all the time, but
it's much more likely that the group will stay consistent and the pain will be
distributed evenly.

figuring it out itself.

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.

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.

FooInfoBase became FooInfo
FooInfo became FooInfoProxy

Because of the initialization bug, it wasn't consistent anyway.

Moved DescCache template functions from .hh to .cc file.
Also fixed lots of line-wrapping problems, and some irregular indentation.

Mostly just config.ini updates, though the different response
latency for bad addresses caused very minor timing changes
in the O3 Linux boot tests.

Previously there was one per bus, which caused some coherence problems
when more than one decided to respond. Now there is just one on
the main memory bus. The default bus responder on all other buses
is now the downstream cache's cpu_side port. Caches no longer need
to do address range filtering; instead, we just have a simple flag
to prevent snoops from propagating to the I/O bus.

env is used as a local variable all over the place and sometimes it is
easy to get confused as to whether the global env or local env is being
used. This will become especially important when I change the way we
support our variants.

1) -L is automatically added, so don't do it ourselves
2) prepend the paths for gzstream and libelf so they are certain to
come first. The problem is that python might add /usr/lib to the path
and the user might have a locally installed version of libelf installed.

This code compiles, but there are no tests still
|
|
|

|

Just one test (40.m5threads-test-atomic) is set up for now.
These tests require that the m5threads SPARC binaries are present
in /dist or in test-progs.

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.

This frees up needed space for more public flags. Also:
- remove unused Request accessor methods
- make Packet use public Request accessors, so it need not be a friend
