da61c4b3ee CPU: Don't fetch when executing a macroop. 
If the CPL changes mid macroop, the end of the instruction might not be
priveleged enough to execute the beginning.

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
