These were including instruction class definitions from x86 for some
reason. There was no code in those .cc files which actually used
anything from them, as evidenced by the fact that the GCN3_X86 build
still works. No other code in the file was conditionally compiled as of
today.

These were being initialized with BigRegVect brv = {0}, which made the
compiler complain because there is internal structure. The first element
of the union is actually an array, and this was telling it to initialize
that array to scalar 0. It was warning about this which was breaking the
build.
Instead, use zero initlization like BigRegVect brv = {}. This
initializes the first element of the union to all zeroes, with all
padding bits initialized to zero as well.
This satisfies the compiler and avoids a build error.

This version of garnet includes HeteroGarnet which
supports heterogenous interconnect systems, flexible
router and link configurations, and better debugging
resources.
This patch changes the garnet directory structure
to not include the version number. The user will be

Initializing the network bridge with NULL causes it to have
an class error when instatiating a link. The bridge is only
needed whne either a CDC or SerDes is enabled. This is handled
later during construction of the GarnetLink.

VirtIO devices currently request their endianness from the System
object. Instead of explicitly querying the system for its endianness,
expose the device's endianness as a param. This param defaults to the
endianness of a parent object using the Parent proxy (in practice the
system).

There are cases where a system's byte order isn't well-defined from an
ISA. For example, Arm implementations can be either big or little
endian, sometimes depending on a boot parameter. Decouple the CPU byte
order from the System's default byte order by exposing the System's
byte order as a parameter that defaults to big endian for SPARC and
POWER and little endian for everything else.

Either return types, brackets and the function body should all be on
their own line, or the entire function should be on a single line.
Consistently place the * or & up against the variable name and not the
type name. There isn't an official rule for which to use, but the
majority of existing uses were this way.
Add overrides for overridden virtual methods.
These fixes get rid of compiler warnings which are breaking the build
for me.

This has been in this file since it was created in 2009. No global "using
namespace ${NAMESPACE}" should ever appear in a .hh file since then that
namespace is "used" in all files that include the .hh, even if they
aren't aware of it or even actively don't want to.

When isa_traits.hh hopefully goes away in the not too distant future,
this constant will need somewhere to live so ARM components can find it.
There are valid arguments that this should not be a constant in the
first place, but that's outside the scope of this change.

When a test is complete, the output files are in a random folder
in /tmp.
This commit adds a procedure copying those files to
testing-results/SuiteUID/TestUID/ folder, where SuiteUID and
TestUID are the corresponding uid's of the test.
This procedure is triggered after a test is complete and before
the folder in /tmp being removed.

Log object should remain being a singleton throughout the program.
The current code creates multiple Log objects, which at least
causes the issues of missing outputs in stdout.
E.g., "Logging call to command", which logs which command is
being called in a subprocess, is missing from stdout.

Add NVM interface to memory controller.
This can be used with or instead of the existing
DRAM interface. Therefore, a single controller can interface
to either DRAM or NVM, or both.
Specifically, a memory channel can be configured as:
- Memory controller interfacing to DRAM only
- Memory controller interfacing to NVM only
- Memory controller interfacing to both DRAM and NVM
How data is placed or migrated between media types is outside
of the scope of this change.
The NVM interface incorporates new static delay parameters
for read and write completion. The interface defines a 2
stage read to manage non-deterministic read delays while
enabling deterministic data transfer, similar to NVDIMM-P.
The NVM interface also includes parameters to define
read and write buffers on the media side (on-DIMM). These are
utilized to quickly offload commands and write data, mitigating
the effects of lower latency and bandwidth media characteristics.
