These had been marked as non-speculative so that their execute
functions would only be called if the instruction should really be
executed. Instead, we can return faults which will cause the same
behavior when the instruction is committed and let the instruction
execute as normal.

The Nop format mostly just made instructions that inherited from the
Nop base class but with different mnemonics, so there doesn't need
to be very much dynamic content.

to transition to clock gated when idle, but not to power gated. When

This test has been broken since 70176fecd1ff04 in 2014. The problem was
that the array size in the test was technically not constant because it
was based on an int variable that wasn't declared as const. That
prevented g++ from resolving it as a template parameter. Before the
change mentioned above, the implementation wasn't based on templates.

Recent Linux kernels for AArch64 have changed their start addresses
but we still want to relocate the kernel to 0x80080000 which
required hacking the load_addr_mask in Realview.py to be 0x7ffffff
from 0xfffffff to mask off the proper number of MSBs to load the
kernel in the desired location. To avoid having to make this change
in the future again, we auto-calculate the load_addr_mask if it is
specified as 0x0 in the System sim-object to find the most restrictive
address mask instead of having the configuration specify it. If the
configuration does specify the address mask, we use it instead of
auto-calculating.

This change adds a script to generate graphs from the stats file
output by the configuration script low_power_sweep.py.
The graphs show stacked bars for time spent and energy consumed
wherein each component of the stacked bar represents a DRAM power
state (Idle, Refresh, Active, Active Power-down, Precharge Power-down
and Self-refresh). The script generates one plot per delay value. It
also generates a pdf (--pdf option) in which the graphs are laid out
such that you can easily compare how the increasing delay and other
swept params affect the resulting energy.

This change adds a Python script to sweep a few parameters with a
goal to trigger transitions to the low power states of the DRAM
controller.
This script is largely based on the sweep.py but is helpful to study
the impact of inter-transaction delay on the behaviour of the DRAM
in addition to typical sweep params like stride size, bank
utilization and read percent. An idle period is added as the last
traffic generator state to target hitting self-refresh.

This patch syncs the DRAMPower library of gem5 to the
external github (https://github.com/ravenrd/DRAMPower).
The version pulled in is the commit:
90d6290f802c29b3de9e10233ceee22290907ce6
from 30th Oct. 2016.
This change also modifies the DRAM Ctrl interaction with the
DRAMPower, due to changes in the lib API in the above version.
Previously multiple functions were called to prepare the power
lib before calling the function that would calculate the enery. With
the new API, these functions are encompassed inside the function to
calculate the energy and therefore should now be removed from the
DRAM controller.
The other key difference is the introduction of a new function called
calcWindowEnergy which can be useful for any system that wants
to do measurements over intervals. For gem5 DRAM ctrl that means we
now need to accumulate the window energy measurements into the total
stat.

This patch allows the user to specify more than one
power model for any given Clocked Object. This is
useful and some times necessary to properly model

The ideal solution would be to have a DictParam
to replace the VectorParam so each model can have
a name and can be identified in the stats file.

The helper script to list changes currently only looks at the changes
between a branch point and two heads. This helps performance, but
sometimes misclassifies changes that exist both in the upstream
branch before the branch point and in a feature branch. Such changes
should normally not exist, but can be the product of an incorrect
rebase.
This change adds an option to the helper script to search the entire
upstream repo history when determining the set of upstream
changes. When this option is provided, the script lists the changes
that exist upstream before the branch point and in the feature branch
as "Incorrectly rebased changes".

The python conversion module was really repetitive and fragmented,
where some types of conversions use common code, and some use hand
written case statements which did something very similar. Also, some
types like Voltage could only handle V and mV but no other scaling
prefix.
This change restructures the module to centralize a lot of the unit
handling code into toFloat, and makes the various other functions use
it.
