config: revamp x86 config to avoid appending to SimObjectVectors
A significant contributor to the need for adoptOrphanParams()
is the practice of appending to SimObjectVectors which have
already been assigned as children. This practice sidesteps the
assignment operation for those appended SimObjects, which is
where parent/child relationships are typically established.
This patch reworks the config scripts that use append() on
SimObjectVectors, which all happen to be in the x86 system
configuration. At some point in the future, I hope to make
SimObjectVectors immutable (by deriving from tuple rather than
list), at which time this patch will be necessary for correct
operation. For now, it just avoids some of the warning
messages that get printed in adoptOrphanParams().

config: tweak ruby configs to clean up hierarchy
Re-enabling implicit parenting (see previous patch) causes current
Ruby config scripts to create some strange hierarchies and generate
several warnings. This patch makes three general changes to address
these issues.
1. The order of object creation in the ruby config files makes the L1
caches children of the sequencer rather than the controller; these
config ciles are rewritten to assign the L1 caches to the
controller first.
2. The assignment of the sequencer list to system.ruby.cpu_ruby_ports
causes the sequencers to be children of system.ruby, generating
warnings because they are already parented to their respective
controllers. Changing this attribute to _cpu_ruby_ports fixes this
because the leading underscore means this is now treated as a plain
Python attribute rather than a child assignment. As a result, the
configuration hierarchy changes such that, e.g.,
system.ruby.cpu_ruby_ports0 becomes system.l1_cntrl0.sequencer.
3. In the topology classes, the routers become children of some random
internal link node rather than direct children of the topology.
The topology classes are rewritten to assign the routers to the
topology object first.

config: reinstate implicit parenting on parameter assignment
Last summer's big rewrite of the initialization code (in
particular cset
6efc3672733b) got rid of the implicit parenting
that used to occur when an unparented SimObject was assigned as
a parameter value to another SimObject. The idea was that the
new adoptOrphanParams() step would catch these anyway so it was
unnecessary.
Unfortunately it turns out that adoptOrphanParams() has some
inherent instability in that the parent that does the adoption
depends on the config tree traversal order. Even making this
order deterministic (e.g., by traversing children in
alphabetical order) can introduce unwanted and unexpected
hierarchy changes between similar configs (e.g., when adding a
switch_cpu in place of a cpu), causing problems when trying to
restore checkpoints across similar configs. The hierarchy
created by implicit parenting is more stable and more
controllable, so this patch turns that behavior back on.
This patch also cleans up some long-standing holes regarding
parenting of SimObjects that are created in class definitions
(either in the body of the class, or as default parameters).
To avoid breaking some existing config files, this necessitated
changing the error on reparenting children to a warning. This
change fixes another bug where attempting to print the prior
error message would fail on reparenting SimObjectVectors
because they lack a _parent attribute. Some further issues
with SimObjectVectors were cleaned up by getting rid of the
get_parent() call (which could cause errors with some
SimObjectVectors where there was no single parent to return)
with has_parent() (since all the uses of get_parent() were just
boolean tests anyway).
Finally, since the adoptOrphanParam() step turned out to be so
problematic, we now issue a warning when it actually has to do
an adoption. Future cleanup of config files will get rid of
current warnings.

O3: Fix issue with interrupts/faults occuring in the middle of a macro-op
This patch fixes two problems with the O3 cpu model. The first is an issue
with an instruction fetch causing a fault on the next address while the
current macro-op is being issued. This happens when the micro-ops exceed
the fetch bandwdith and then on the next cycle the fetch stage attempts
to issue a request to the next line while it still has micro-ops to issue
if the next line faults a fault is attached to a micro-op in the currently
executing macro-op rather than a "nop" from the next instruction block.
This leads to an instruction incorrectly faulting when on fetch when
it had no reason to fault.
A similar problem occurs with interrupts. When an interrupt occurs the
fetch stage nominally stops issuing instructions immediately. This is incorrect
in the case of a macro-op as the current location might not be interruptable.

ruby: dbg: use system ticks instead of cycles
Gabe Black [Fri, 29 Apr 2011 08:46:19 +0000 (04:46 -0400)]
Util: Replace mkblankimage.sh with the new gem5img.py.
This change replaces the mkblankimage.sh script, used for creating new disk
images, with a new gem5img.py script. The new version is written in python
instead of bash, takes its parameters from command line arguments instead of
prompting for them, and finds a free loopback device dynamically instead of
hardcoding /dev/loop1. The file system used is now optionally configurable,
and the blank image is filled by a "hole" left by lseek and write instead of
literally filling it with zeroes.
The functionality of the new script is broken into subcommands "init",
"mount", "umount", "new", "partition", and "format". "init" creates a new file
of the appropriate size, partitions it, and then formats the first (and only)
new parition. "mount" attaches a new loopback device to the first parition of
the image file and mounts it to the specified mount point. "umount" unmounts
the specified mount point and identifies and cleans up the underlying loopback
device. "new", "partition", and "format" are the individual stages of "init"
but broken out so they can be run individually. That's so an image can be
reinitialized in place if needed.
Two features of the original script are being dropped. The first is the
ability to specify a source directory to copy into the new file system. The
second is the ability to specify a list of commands to run which are expected
to (but not required to) update the permissions of the files in the new fs.
Both of these seem easy enough to do manually, especially given the "mount"
and "umount" commands, that removing them would meaningfully simplify the
script without making it less useful.

Therefore all links by default are 16 bytes wide and thus work with Garnet's
uniform link bandwidth assumption.

network: adjusted default endpoint bandwidth
The simple network's endpoint bandwidth value is used to adjust the overall
bandwidth of the network. Specifically, the ration between endpoint bandwidth
and the MESSAGE_SIZE_MULTIPLIER determines the increase. By setting the value
to 1000, that means the bandwdith factor specified in the links translates to
the link bandwidth in bytes. Previously, it was increasing that value by 10.
This patch will likely require a reset of the ruby regression tester stats.

network: basic link bw for garnet and simple networks
This patch ensures that both Garnet and the simple networks use the bw value
specified in the topology. To do so, the patch generalizes the specification
of bw for basic links. This value is then translated to the specific value
used by the simple and Garnet networks. Since Garent does not support
non-uniformed link bandwidth, the patch also adds a check to ensure all bws are
equal.

network: convert links & switches to first class C++ SimObjects
This patch converts links and switches from second class simobjects that were
virtually ignored by the networks (both simple and Garnet) to first class
simobjects that directly correspond to c++ ojbects manipulated by the
topology and network classes. This is especially true for Garnet, where the
links and switches directly correspond to specific C++ objects.
By making this change, many aspects of the Topology class were simplified.
