The Minor draining fixes affect perturb the timing slightly since it
affects how the simulator is drained. Update reference statistics to
reflect this expected change.
|
|
|
|
Add the Minor CPU to the RealView and RealView64 full switcheroo
tests.
|
|
|
|
Somehow this one seems to have slipped through. Perhaps
non-determinism somewhere?
|
|
|
|
The pc-switcheroo test cases has slightly different timing after
decoupling draining from the SimObject hierarchy. This is expected
since objects aren't drained in the exact same order as before.
|
|
Draining is currently done by traversing the SimObject graph and
calling drain()/drainResume() on the SimObjects. This is not ideal
when non-SimObjects (e.g., ports) need draining since this means that
SimObjects owning those objects need to be aware of this.
This changeset moves the responsibility for finding objects that need
draining from SimObjects and the Python-side of the simulator to the
DrainManager. The DrainManager now maintains a set of all objects that
need draining. To reduce the overhead in classes owning non-SimObjects
that need draining, objects inheriting from Drainable now
automatically register with the DrainManager. If such an object is
destroyed, it is automatically unregistered. This means that drain()
and drainResume() should never be called directly on a Drainable
object.
While implementing the new functionality, the DrainManager has now
been made thread safe. In practice, this means that it takes a lock
whenever it manipulates the set of Drainable objects since SimObjects
in different threads may create Drainable objects
dynamically. Similarly, the drain counter is now an atomic_uint, which
ensures that it is manipulated correctly when objects signal that they
are done draining.
A nice side effect of these changes is that it makes the drain state
changes stricter, which the simulation scripts can exploit to avoid
redundant drains.

The full-system SPARC tests depend on several binaries that aren't
generally available to the wider community. Flag the tests as skipped
instead of failed if these binaries can't be found.

This update includes the changes to whole-line writes, the refinement
of Read to ReadClean and ReadShared, the introduction of CleanEvict
for snoop-filter tracking, and updates to the DRAM command scheduler
for bank-group-aware scheduling.
Needless to say, almost every regression is affected.
|
|
This patch adds a parameter to the BaseCache to enable a read-only
cache, for example for the instruction cache, or table-walker cache
(not for x86). A number of checks are put in place in the code to
ensure a read-only cache does not end up with dirty data.
A follow-on patch adds suitable read requests to allow a read-only
cache to explicitly ask for clean data.

|
The addition of a virtual timer affects stats in minor and o3.
|
|
Only one regression is affected.
|
|
|
|
|
|
|
|
|
|
Very small differences in IQ-specific O3 stats.
|
|
Very small changes to iew.predictedNotTakenIncorrect
and iew.branchMispredicts. Looks like similar updates
were committed on April 3 (changeset 235ff1c046df), but
only for the quick tests.
|
|
The change in 20.parser is from new x87 instructions. The change to
pc-o3-timing is not clear to me. It seems that this test might be invoking
some undefined behavior.

A few regressions were still considered long, but finished well within
the 180 seconds. They are only a handful (mostly mcf in atomic).

A recent changeset of mine (http://repo.gem5.org/gem5/rev/4cfe55719da5)
inadvertently fixed a bug in the Minor CPU model which caused it to treat
software prefetches as regular loads. Prior to this changeset, Minor
did an ad-hoc generation of memory commands that left out the PF check;
because it now uses the common code that the other CPU models use,
it generates prefetches properly. These stat changes reflect the fact
that the Minor model now issues SoftPFReqs.

This patch takes a first stab at recategorising the regression tests
based on actual run times. The simple-atomic and simple-timing runs of
vortex and twolf all finish in less than 180 s, and they are
consequently moved from long to quick. All realview64 linux-boot
regressions take more than 700 s, and they are therefore moved to
long.
Later patches will rename quick to short, and further divide the
regressions into short, medium and long.

Add a set of scripts to automatically test checkpointing in the
regression framework. The checkpointing tests are similar to the
switcheroo tests, but instead of switching between CPUs, they
checkpoint the system and restore from the checkpoint again. This is
done at regular intervals, typically while booting Linux.
The implementation is fairly straight forward, with the exception that
we have to work around gem5's inability to restore from a checkpoint
after a system has been instantiated. We work around this by forking
off child processes that does the actual simulation and never
instantiate a system in the parent process unless a maximum checkpoint
count is reached (in which case we just simulate the system to
completion in the parent).
Checkpoint testing is currently only enabled 32- and 64-bit ARM
systems using atomic CPUs.
Note: An unfortunate side-effect of forking is that every new process
will overwrite the stats and terminal output from the previous
process. This means that the output directory only contains data from
the last checkpoint.

Align with observed run-times just above 4 hours for some hosts.

Minor differences apparently from recent changes
|
|
This is a bulk update of stats to match the changes to cache timing,
interconnect timing, and a few minor changes to the o3 CPU.
|
|
This patch introduces a few subclasses to the CoherentXBar and
NoncoherentXBar to distinguish the different uses in the system. We
use the crossbar in a wide range of places: interfacing cores to the
L2, as a system interconnect, connecting I/O and peripherals,
etc. Needless to say, these crossbars have very different performance,
and the clock frequency alone is not enough to distinguish these
scenarios.
Instead of trying to capture every possible case, this patch
introduces dedicated subclasses for the three primary use-cases:
L2XBar, SystemXBar and IOXbar. More can be added if needed, and the
defaults can be overridden.
|
|
Allow the user to send signals such as Ctrl C to the gem5 runs. Note
that this assumes coreutils >= 8.13, which aligns with Ubuntu 12.04
and RHE6.

Reflect changes in the tester behaviour.
|
|
The MemTest class really only tests false sharing, and as such there
was a lot of old cruft that could be removed. This patch cleans up the
tester, and also makes it more clear what the assumptions are. As part
of this simplification the reference functional memory is also
removed.
The regression configs using MemTest are updated to reflect the
changes, and the stats will be bumped in a separate patch. The example
config will be updated in a separate patch due to more extensive
re-work.
In a follow-on patch a new tester will be introduced that uses the
MemChecker to implement true sharing.

This patch removes the three MIPS and SPARC regressions that use the
deprecated InOrderCPU.
This is the first step in completely removing the code from the tree,
avoiding confusion, and focusing all development efforts on the
MinorCPU. Brave new world.

Changes due to speculative execution of an unaligned PC, introduction
of TLB stats, changes and re-work of the prefetcher, and the
introduction of rank-wise refresh in the DRAM controller.
|
|
Re-use the existing traffic generator regression, and enable the stack
distance calculation in the comm monitor, along with the verification
stack.
The traffic generator config is also tuned to not increase the
run-time too much (and actually have some address re-use).

|
|
|
|
Fixing up the uninitialised values changes two of the x86 Linux boot
regressions slightly.
