The following CL delayed program exit and changed the stats for many if not
most of the SE mode regressions.

The following change removed a write to an integer register when completing
a system call. This changed the reference statistics slightly.

Line everything up again.
|
|
The EIOProcess class was removed recently and it was the only other class
which derived from Process. Since every Process invocation is also a
LiveProcess invocation, it makes sense to simplify the organization by
combining the fields from LiveProcess into Process.
|
|
|
|
No one appears to be using it, and it is causing build issues
and increases the development and maintenance effort.
|
|
Mostly just splitting out the floats ops and corresponding
reads/writes.

Removed unused stats, now counting WriteLineReq, and changed how
uncacheable writes are handled while responses are outstanding.
|
|
Small changes to the branch predictor and BTB caused stats changes
throughout.
|
|
SE O3 runs see an additional reg read per mmap() call.

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.

Very small differences in IQ-specific O3 stats.

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 is a bulk update of stats to match the changes to cache timing,
interconnect timing, and a few minor changes to the o3 CPU.
|
|
|
|
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.
|
|
|
|
|
|
|
|
Somehow these seem to have been missed.

This patch bumps the stats to reflect the addition of the snoop filter
and snoop stats, the change from bus to crossbar, and the updates to
the ARM regressions that are now using a different CPU and cache
configuration. Lastly, some minor changes are expected due to the
activation cleanup of the CPUs.
|
|
This patch updates the stats to reflect the fixes and changes to the
CPU (mainly the o3), and the caches.
|
|
This patch changes the perlbmk regression script from the large to the
medium dataset to reduce the regression run time. For all ISAs and CPU
models, the total perlbmk host CPU time with the large dataset is
roughly 12 hours (constituting >30% of the total regression host
time). There is, most likely, almost no added value in terms of code
coverage for this rather excessive run time.
|
|
Also updates many out of date config files.
|
|
Updating the stats to match the current behaviour.
|
|
This patch adds regression tests results and test harnesses
for the Minor CPU on ARM and ALPHA.
|
|
Only printing one rather than two args for the ignored syscall
warning means the count of register accesses has changed on
a few runs. Oddly only Alpha Tru64 seems to have any ignored
syscalls in the regression tests.
|
|
Mostly small differences in total ticks, but O3 stall causes
shifted significantly.
30.eon does speed up by ~6% on Alpha and ARM, and 50.vortex
by 4.5% on ARM. At the other extreme, X86 70.twolf is 0.8%
slower.
