Coherence protocol change basically got rid
of UpgradeReqs in L2 caches, other minor
related cache stat changes.
|
|
Make diff-out sort stats changes by percentage
by default, with '-a' to use current alpha sort
(instead of requiring '-p' to sort by percentage).
Other minor options cleanup too.
|
|
Add '-s' flag to diff command generating outdiff
file so we have positive confirmation when
outputs match.
|
|
Because the handling of the E state for multilevel caches
has changed, stats are affected for any non-ruby config
with caches, even uniprocessor simple CPU.

Small changes in tests with data races due to new object creation
order.
|
|
Orphan SimObjects (not in the config hierarchy) could get
created implicitly if they have a port connection to a SimObject
that is in the hierarchy. This means that there are objects on
the C++ SimObject list (created via the C++ SimObject
constructor call) that are unknown to Python and will get
skipped if we walk the hierarchy from the Python side (as we are
about to do). This patch detects this situation and prints an
error message.
Also fix the rubytester config script which happened to rely on
this behavior.
|
|
Enforce that the Python Root SimObject is instantiated only
once. The C++ Root object already panics if more than one is
created. This change avoids the need to track what the root
object is, since it's available from Root.getInstance() (if it
exists). It's now redundant to have the user pass the root
object to functions like instantiate(), checkpoint(), and
restoreCheckpoint(), so that arg is gone. Users who use
configs/common/Simulate.py should not notice.

Rename 'responder_set' to 'use_default_range'.

Some subset of UpgradeReq messages shifted to the
new SCUpgradeReq type. Other than that there
are no significant differences.

Previously the return value ignored missing/added stats,
making the regressions not tell you when you needed to
update the reference stats because of these changes.
Also stop filtering distributions when reporting these;
not sure why we did that in the first place.
Also get rid of obsolete hacks for the "fetch-loss" stats
that have been gone for a long time.

I forgot to turn on ruby when updating the stats before.

On the config end, if a shared L2 is created for the system, it is
parameterized to have n sharers as defined by option.num_cpus. In addition to
making the cache sharing aware so that discriminating tag policies can make use
of context_ids to make decisions, I added an occupancy AverageStat and an occ %
stat to each cache so that you could know which contexts are occupying how much
cache on average, both in terms of blocks and percentage. Note that since
devices have context_id -1, having an array of occ stats that correspond to
each context_id will break here, so in FS mode I add an extra bucket for device
blocks. This bucket is explicitly not added in SE mode in order to not only
avoid ugliness in the stats.txt file, but to avoid broken stats (some formulas
break when a bucket is 0).

This patch includes the necessary regression updates to test the new ruby
configuration system. The patch includes support for multiple ruby protocols
and adds the ruby random tester. The patch removes atomic mode test for
ruby since ruby does not support atomic mode acceses. These tests can be
added back in when ruby supports atomic mode for real.
