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.

973d8b8b13 InOrder: Import new inorder CPU model from MIPS. 
This model currently only works in MIPS_SE mode, so it will take some effort
