This patch simply takes a first step to use the NULL ISA build for
tests that do not make use of a CPU. Most of the Ruby tests could go
the same way, but to avoid duplicating a lot of compilation targets
that will have to wait until Ruby is built as a library and linked in
independently.

This patch updates the stats to reflect the: 1) addition of the
internal queue in SimpleMemory, 2) moving of the memory class outside
FSConfig, 3) fixing up of the 2D vector printing format, 4) specifying
burst size and interface width for the DRAM instead of relying on
cache-line size, 5) performing merging in the DRAM controller write
buffer, and 6) fixing how idle cycles are counted in the atomic and
timing CPU models.
The main reason for bundling them up is to minimise the changeset
size.
|
|
The statistics for 30.eio-mp, pc-simple-timing-ruby tests are being updated
to incorporate the changes due to recent patches.
|
|
This patch removes the sparse histogram total from the CommMonitor
stats. It also bumps the stats after the unit fixes in the atomic
cache access. Lastly, it updates the stats to match the new port
ordering. All numbers are the same, and the only thing that changes is
which master corresponds to what port index.
|
|
This patch extends the existing system builders to also include a
syscall-emulation builder. This builder is deployed in all
syscall-emulation regressions that do not involve Ruby,
i.e. o3-timing, simple-timing and simple-atomic, as well as the
multi-processor regressions o3-timing-mp, simple-timing-mp and
simple-atomic-mp (the latter are only used by SPARC at this point).
The values chosen for the cache sizes match those that were used in
the existing config scripts (despite being on the large
side). Similarly, a mem_class parameter is added to the builder base
class to enable simple-atomic to use SimpleMemory and o3-timing to use
the default DDR3 configuration.
Due to the different order the ports are connected, the bus stats get
shuffled around for the multi-processor regressions. A separate patch
bumps the port indices. Besides this, all behaviour is exactly the
same.

Ruby's controller statistics have been mostly moved to stats.txt now.
Plus stats.txt for solaris/t1000-simple-atomic and arm/20.parser are
also being updated.
|
|
|
|
This patch updates the stats to reflect the addition of the bus stats,
and changes to the bus layers. In addition it updates the stats to
match the addition of the static pipeline latency of the memory
conotroller and the addition of a stat tracking the bytes per
activate.
|
|
This is due to op class, function call, walker patches.

The new changeset that can reorder Ruby profilers will cause the ruby.stats
files to reordered statistics (the point of the patch). Update the references
to ensure that these changes are reflected in regressions.
|
|
|
|
|
|
|
|
This patch updates the stats for the affected stats. All the changes
are minimal (in the <0.01% range).
|
|
This patch updates the stats after splitting the bus retry into
waiting for the bus and waiting for the peer.
|
|
|
|
|
|
|
|
This patch bumps the stats to reflect the slight change in how the
retry is handled, and also the pruning of some redundant stats.
|
|
|
|
This patch updates the regression stats to reflect that they are using
the SimpleDDR3 controller by default.
|
|
The actual statistical values are being updated for only two tests belonging
to sparc architecture and inorder cpu: 00.hello and 02.insttest. For others
the patch updates config.ini and name changes to statistical variables.

This changeset adds a set of tests that stress the CPU switching
code. It adds the following test configurations:
* tsunami-switcheroo-full -- Alpha system (atomic, timing, O3)
* realview-switcheroo-atomic -- ARM system (atomic<->atomic)
* realview-switcheroo-timing -- ARM system (timing<->timing)
* realview-switcheroo-o3 -- ARM system (O3<->O3)
* realview-switcheroo-full -- ARM system (atomic, timing, O3)
Reference data is provided for the 10.linux-boot test case. All of the
tests trigger a CPU switch once per millisecond during the boot
process.
The in-order CPU model was not included in any of the tests as it does
not support CPU handover.

This patch adds support for reading input traces encoded using
protobuf according to what is done in the CommMonitor.
A follow-up patch adds a Python script that can be used to convert the
previously used ASCII traces to protobuf equivalents. The appropriate
regression input is updated as part of this patch.

The EIO tests depend on the EIO support from the "encumbered"
repository, which means that they are not normally built with
gem5. This causes all EIO related tests to fail, which is both
annoying and confusing. This patch addresses this by adding support
for skipping tests if certain conditions (e.g., the presence of a
SimObject) can not be met. It introduces the following Python
functions that can be called from within a test case:
* skip_test -- Skip a test and optionally print why the test was
skipped.
* has_sim_object -- Test if a SimObject exists.
* require_sim_object -- Test if a SimObject exists and skip, or
optionally fail, the test if not.
Additionally, this patch updates the EIO tests to check for the
presence of EioProcess.

This patch updates the regression stats to reflect the change in the
traffic gen configuration.
|
|
This patch changes the traffic generator period such that it does not
completely saturate the DRAM controller and create an ever-growing
backlog in the queued port.
A separate patch updates the stats.

This patch updates the stats for the regressions that were affected by
the typo in the simple-atomic-mp configuration.
|
|
This patch updates the stats to reflect the changes in the L2 MSHRs,
as the latter are now uniform across the regressions.
|
|
This patch updates the stats to reflect the change in the default
system clock from 1 THz to 1GHz. The changes are due to the DMA
devices now injecting requests at a lower pace.
|
|
This patch bumps the stats to match the use of SimpleDRAM instead of
SimpleMemory in all inorder and O3 regressions, and also all
full-system regressions. A number of performance-related stats change,
and a whole bunch of stats are added for the memory controller.
|
|
This patch updates the stats after removing the zero-time send used in
the DMA port.
