64ed39f61b pseudo inst: Add new wake cpu instruction for sending a message to wake a cpu. 
It's instantaneous and so it's somewhat bogus, but it's a first step.

f0fb3ac060 cpu: provide a wakeup mechanism that can be used to pull CPUs out of sleep. 
Make interrupts use the new wakeup method, and pull all of the interrupt
stuff into the cpu base class so that only the wakeup code needs to be updated.
I tried to make wakeup, wakeCPU, and the various other mechanisms for waking
and sleeping a little more sane, but I couldn't understand why the statistics
were changing the way they were.  Maybe we'll try again some day.

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.

the primary and secondary channel.

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

3087be945d Output: Include gzstream package to allow automatically-gzipped output 
The gzstream package provides an ostream-interface for writing gzipped files.
The package comes from:
    http://www.cs.unc.edu/Research/compgeom/gzstream/
And is distributed under the LGPL license. Both the license and version
information has been preservered, though all other files in the package have
been purged. Minor modifications to the code have been made. The output module
detects when a filename ends in .gz and constructs an ogzstream object instead
of an ofstream object. This works for both the create(...) and find(...)
commands. Additionally, since gzstream objects needs to be closed to ensure
proper file termination, I have the output deconstructor deleting all ostream's
that it manages on behalf of find(...). At the moment, the only output file
that I know this functionality works for is stats, i.e. by specifying
"--stats-file=m5stats.txt.gz" on the command line.

4d64d7664c SCons: Allow top level directory of EXTRAS able to contain SConscripts. 
The current EXTRAS will fail if the top level directory pointed to by EXTRAS
has a SConscript file in it.  We allow this by including the directory name
of the EXTRA in the build directory which prevents a clash between
src/SConscript and extra/SConscript. Maintain compatibility with older uses
of EXTRAS by adding a -I for each top level extra directory.

In DEBUG mode, this does a dynamic_cast and asserts that the result is

intended for cases where the cast should always succeed and what's
desired is a debugging check to make sure.

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.

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.

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.

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.
