This patch removes some of the unused typedefs. It also moves
some of the typedefs from Global.hh to TypeDefines.hh. The patch
also eliminates the file NodeID.hh.
|
|
And by "everything" I mean all the quick regressions.
|
|
|

These options were missing from the script ruby_fs.py. This patch adds these
options to the script.

In RubySlicc_ComponentMapping.hh, certain '#define's have been used for
mapping MachineType to GenericMachineType. These '#define's are being
eliminated and the code will now be generated by SLICC instead. Also
are being eliminated some of the unused functions from
RubySlicc_ComponentMapping.sm.

PageTable supported an allocate() call that called back
through the Process to allocate memory, but did not have
a method to map addresses without allocating new pages.
It makes more sense for Process to do the allocation, so
this method was renamed allocateMem() and moved to Process,
and uses a new map() call on PageTable.
The remaining uses of the process pointer in PageTable
were only to get the name and the PID, so by passing these
in directly in the constructor, we can make PageTable
completely independent of Process.

Turns out these are due to diff reporting that files
acutally differed via a non-zero exit code.
|
|
Make DmaDevice::getPort() call PioDevice::getPort() instead
of just copying and pasting the code.
Also move definitions from .hh to .cc file.
|
|
Replace the (broken as of previous changeset) swig_objdecl() method
that allowed/forced you to substitute a whole new C++ struct
definition for SWIG to wrap with a set of export_method* hooks
that let you just declare a set of C++ methods (or other declarations)
that get inserted in the auto-generated struct.
Restore the System get/setMemoryMode methods, and use this mechanism
to specialize SimObject as well, eliminating teh need for sim_object.i.
Needed bits of sim_object.i are moved to the new pyobject.i.
Also sucked a little SimObject specialization into cxx_param_decl()
allowing us to get rid of src/sim/sim_object_params.hh. Now the
generation and wrapping of the base SimObject param struct is more
in line with how derived objects are handled.
--HG--
rename : src/python/swig/sim_object.i => src/python/swig/pyobject.i

- Move the random bits of SWIG code generation out of src/SConscript
file and into methods on the objects being wrapped.
- Cleaned up some variable naming and added some comments to make
the process a little clearer.
- Did a little generated file/module renaming:
- vptype_Foo now Foo_vector
- init_Foo is now Foo_init
This makes it easier to see all the Foo-related files in a
sorted directory listing.
- Made cxx_predecls and swig_predecls normal SimObject classmethods.
- Got rid of swig_objdecls hook, even though this breaks the System
objects get/setMemoryMode method exports. Will be fixing this in
a future changeset.

'tickEvent' was not being serialized as in its place 'event' was being used.
This patch rectifies this error.

These faults take varargs to their constructors which they print into a string
and pass to the M5DebugFault base class. They are basically faults wrapped
around panics, faults, warns, and warnonce-es so that they happen only at
commit.
|
|
All of the classes will now be available in both modes, and only
GenericPageTableFault will continue to check the mode for conditional
compilation. It uses a process object to handle the fault in SE mode, and
for now those aren't available in FS mode.

By using an underscore, the "." is still available and can unambiguously be
used to refer to members of a structure if an operand is a structure, class,
etc. This change mostly just replaces the appropriate "."s with "_"s, but
there were also a few places where the ISA descriptions where handling the
extensions themselves and had their own regular expressions to update. The
regular expressions in the isa parser were updated as well. It also now
looks for one of the defined type extensions specifically after connecting "_"
where before it would look for any sequence of characters after a "."
following an operand name and try to use it as the extension. This helps to
disambiguate cases where a "_" may legitimately be part of an operand name but
not separate the name from the type suffix.
Because leaving the "_" and suffix on the variable name still leaves a valid
C++ identifier and all extensions need to be consistent in a given context, I
considered leaving them on as a breadcrumb that would show what the intended
type was for that operand. Unfortunately the operands can be referred to in
code templates, the Mem operand in particular, and since the exact type of Mem
can be different for different uses of the same template, that broke things.

This patch makes O3 CPU work along with the Ruby memory model. Ruby
overwrites the senderState pointer with another pointer. The pointer
is restored only when Ruby gets done with the packet. LSQ makes use of
senderState just after sendTiming() returns. But the dynamic_cast returns
a NULL pointer since Ruby's senderState pointer is from a different class.
Storing the senderState pointer before calling sendTiming() does away with
the problem.

This constant will have the same value as FULL_SYSTEM but will not be usable
by the preprocessor. It can be substituted into places where FULL_SYSTEM is
used in a C++ context and will make it easier to find which parts of the
simulator still use FULL_SYSTEM with the preprocessor using grep.

This comment was supposed to be added to an earlier change as part of review
feedback, but I accidentally left it out when I pushed. Add it in now.
|
|
There was a change a while ago that refactored some scons stuff which got rid
of cpu_models.py but also accidentally got rid of the ISA parser as a source
for its target files. That meant that changes which affected the parser
wouldn't cause a rebuild unless they also changed one of the description
files. This change fixes that.

Translating MSR addresses into MSR register indices took a lot of space in the
TLB source and made looking around in that file awkward. This change moves
the lookup into its own file to get it out of the way. It also changes it from
a switch statement to a hash map which should hopefully be a little more
efficient.

Initialize flags via the Event constructor instead of calling
setFlags() in the body of the derived class's constructor. I
forget exactly why, but this made life easier when implementing
multi-queue support.
Also rename Event::getFlags() to isFlagSet() to better match
common usage, and get rid of some unused Event methods.
|
|
Use exitSimLoop() function instead of explicitly scheduling
on mainEventQueue (which won't work once we go to multiple
event queues). Also introduced a local params variable to
shorten a lot of expressions.
|
|
Print IpAddress params in dot notation for readability.
Properly compare IpAddress objects (by value and not object identity).
Also fix up derived param classes (IpNetmask and IpWithPort)
similarly.
|
|
This change is a significant reorganization of the MIPS fault code that gets
rid of duplication, fixes some bugs, doubtlessly introduces others, and adds
names for the exception code constants.
|
|
|
|
Neither of these functions were used.
|
|
|
|
Also fix the newly exposed and preexisting compile errors. This code hasn't
been exposed in a while, and it's not up to date with the rest of gem5.
|
|
Pass in a bool to indicate if the fault is from a store instead of having two
different classes. The classes were also misleadingly named since loads are
also processed by the DTB but should return ITB faults since they aren't
stores. The TLB may be returning the wrong fault in this case, but I haven't
looked at it closely.
|
|
|
|
Since they're so closely linked, they should be next to each other in the
file.
|
|
|
|
These functions aren't called anywhere and are probably only theoretically
useful.
|
|
Get rid of Fault classes left over from when this file was copied from Alpha,
and rename ArithmeticOverflowFault to be IntegerOverflowFault and get rid of
the old IntegerOverflowFault stub. The Integer version is what's actually in
the manual, but the Arithmetic version had the implementation.

CRTP stands for the curiously recurring template pattern.

Make sure it's declared iff it's also defined.

It was technically possible but clumsy to determine what endianness a guest
was configured with using the state in byteswap.hh. This change makes that
information available more directly.
Also get rid of unused (and mildly redundant) ByteOrderDiffers constant.
|
|
The remaining ones are more complicated and may require adjustments in other
parts of the simulator.
