intended. Also get rid of the 64 bit only rip relative addressed version since
64 bit and real mode are mutually exclusive.

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.

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

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.

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.

f0fb3ac060 cpu: provide a wakeup mechanism that can be used to pull CPUs out of sleep. 
Make interrupts use the new wakeup method, and pull all of the interrupt
stuff into the cpu base class so that only the wakeup code needs to be updated.
I tried to make wakeup, wakeCPU, and the various other mechanisms for waking
and sleeping a little more sane, but I couldn't understand why the statistics
were changing the way they were.  Maybe we'll try again some day.

0876c822dd tracing: panic() if people try to use tracing, but TRACING_ON is not set.
