7fdc7303c2 - add "void reset(unsigned type)" method to every I/O device. 
Some devices already had one.  Some I had to add an empty one.
  I did a little cleaning of init() methods to make them more uniform
  but generally I left them alone.
- I also put these exact diffs into a patch "patch.iodev-add-reset"
  in case I want to revert these changes for some reason, for example
  if they break an old patch.  It should be deleted after a while.

daf2a9fb55 - add RCS Id to header of every file. This makes it easier to know what's 
going on when someone sends in a modified file.

a4ca526eee - add preprocessor tricks that undefine the OUT symbol if it's already 
been defined elsewhere.  This had to be done in the old pit as well,
  so it's not a new problem by any means.

728252e212 Fixed a small problem in the latching code in the new pit. 
Personal note: case...BREAK;

This makes OpenBSD and QNX a little happier.

Added debug messages.

9aa7a88028 Lots of timer stuff. 
Fixed a "feature" in pc_system.cc with setting timers to small values
that can cause bochs to hang.

Significantly improved the performance of the new PIT.
It's probably ready to become the default now.

Added a preliminary implementation of the slowdown timer
that Bryce and I had talked about.

f229ae1afd - a right shift by 12 was accidently written as one greater than instead of two 2001-08-14 04:53:32 +00:00

fc0ee2dc3e Added compiler define to use the new PIT. 
Also added a hack to keep the OpenBSD timer problem from filling the log.

The new PIT seems to work, but until some
enhancements are made to the way the timers
and devices.cc work, it'll be slower than
the old one.

85b5157a7e Added significant improvements to the new pit. It's about ready for use. 
The only big thing it's lacking right now is testing, which is a
little difficult to do, considering the new interface.  Oh, well.

af1b064007 Added a few access functions to pit, also changed 
the constructor to an init function so that it can
be called at any time.

8d3c28d3de - added comment clarifying that Greg wrote it, and that it's not linked 
with the rest of Bochs yet.
