80d5f34da6 stats: get rid of the convoluted 'database' code. 
Just use the stuff directly and things ought to be more clear

fb74987c52 stats: Try to make the names of things more intuitive. 
Basically, this means renaming several things called data to info, which
is information about the statistics.  Things that are named data now are
actual data stored for the statistic.

f69ea20fc6 stats: cleanup static stats to make startup work. 
This is mainly to allow the unit test to run without requiring the standard
M5 stats from being initialized (e.g. sim_seconds, sim_ticks, host_seconds)

c41c9cf3a6 events: Make trace events happen at the right priority. 
Also, while we're at it, remember that priorities are in the Event class
and add a disable method to disable tracing.

6cfff91d43 Make etherdump timestamps zero-based. 
We previously used the actual wall time for the base timestamps,
making etherdumps non-deterministic.  This fixes that problem and
gets rid of the "malformed packet" at the front that we needed to
provide the right base timestamp to wireshark/tcpdump.

5d029ff11e sycalls: implement mremap() and add DATA flag for getrlimit(). mremap has been tested on Alpha, compiles for the rest but not tested. I don't see why it wouldn't work though. 2009-02-16 17:47:39 -05:00

89ea323250 Update stats for new prefetching fixes. 
Prefetching is not enabled in any of our regressions, so no significant
stat values have changed, but zero-valued prefetch stats no longer
show up when prefetching is disabled so there are noticable changes
in the reference stat files anyway.

89a7fb0393 Fixes to get prefetching working again. 
Apparently we broke it with the cache rewrite and never noticed.
Thanks to Bao Yungang <baoyungang@gmail.com> for a significant part
of these changes (and for inspiring me to work on the rest).
Some other overdue cleanup on the prefetch code too.

312fbb1b48 scons: clean up the main SConstruct file more. 
Add some features to read_command so it works a little bit better
Clean up the mercurial checks.

973d8b8b13 InOrder: Import new inorder CPU model from MIPS. 
This model currently only works in MIPS_SE mode, so it will take some effort
to clean it up and make it generally useful. Hopefully people are willing to
help make that happen!

dd6ea8797f scons: Require SCons version 0.98.1 
This allows me to clean things up so we are up to date with respect to
deprecated features.  There are many features scheduled for permanent failure
in scons 2.0 and 0.98.1 provides the most compatability for that.  It
also paves the way for some nice new features that I will add soon

9e268ae63f scons: Don't build the intermediate static library unless explicitly requested. 
This means that similar to libm5_fast.so, you need to explicitly build
build/ALPHA_SE/libm5_fast.a if you want it.
