   picoseconds now.

 - Permit timestamps to be as far as 2048 ticks apart before we complain
   about invalid timestamps.  Nehalem CPUs seem to be synchronized but only
   within a fraction of a microsecond.
 - Make the Counter code more flexible to poor timestamps.  In general we
   now complain a lot but render as much as we can.
 - Change the scaler behavior so it works better with very long and very
   short traces.  We now set the maximum scale such that it properly
   displays the entire file by default and doesn't permit zooming out
   beyond the file.  This improves other awkward navigation behavior.
   The interval is now set very small which can't be achieved by simply
   dragging the mouse.  Clicking to the left of or right of the scaler bar
   will produce increments of a single, very small, interval now.

   printing it to the terminal.  Now only parse errors go to the terminal.
 - Speedup drawing by raising and lowering tags only once everything has
   been drawn.  Surprisingly, it now takes a little longer to parse than
   it does to draw.

   of various things.

 - Significantly speedup hiding and displaying multiple rows by writing an
   optimized single pass function for each.  This reduces the number of
   tkinter calls required to the minimum.
 - Add a right-click context menu for sources.  Supported commands hide
   the source, hide the whole group the source is in, and bring up a stat
   window.
 - Add a source stat frame that gives an event frequency table as well as
   the total duration for each event type that has a duration.  This can
   be used to see, for example, the total time a thread spent running or
   blocked by a wchan or lock.

 - Rewrite the parser to support the new generic schedgraph interface.
   This no longer requires any custom classes or parsers to support new
   event types.
 - Add an optional command line argument for specifying the clock frequency
   in ghz.  This is useful for traces that do not include KTR_SCHED.

 - Add support for sorting rows by clicking and dragging them to their new
   position.
 - Add support for configuring the cpu background colors.
 - Improve the scaling so a better center is maintained as you zoom.  This
   is not perfect due to precision loss with floats used in the window
   views.
 - Add new colors and a random assignment for unknown event types.  A table
   is used for known event types.  This is the only event specific
   information.

SVN rev 187156 on 2009-01-13 16:44:18Z by jhb

Add support for two new event source types:
- Callwheels traced via KTR_CALLOUT.  Each CPU is assigned a callwheel
  source.  The events on this source are the execution of individual callout
  routines.  Each routine shows up as a green rectangle while it is executed
  and the event details include the function pointer and argument.
- Locks traced via KTR_LOCK.  Currently, each lock name is assigned an event
  source (since the existing KTR_LOCK traces only include lock names and
  not pointers).  This does mean that if multiple locks of the same name are
  manipulated, the source line for that name may be confusing.  However, for
  many cases this can be useful.  Locks are blue when they are held and
  purple when contested.  The contention support is a bit weak due to
  limitations in the rw_rlock() and mtx_lock_spin() logging messages
  currently.  I also have not added support for contention on lockmgr,
  sx, or rmlocks yet.  What is there now can be profitably used to examine
  activity on Giant however.
- Expand the width of the event source names column a bit to allow for some
  of the longer names of these new source types.

SVN rev 187155 on 2009-01-13 16:33:10Z by jhb

- Add some rudimentary support for sorting the list of event sources
  (threads, CPU load counters, etc.).  Each source is tagged with a group
  and an order similar to the SYSINIT SI_SUB_* and SI_ORDER_*.  After
  the file is parsed, all the sources are then sorted.  Currently, the only
  affects of this are that the CPU loads are now sorted by CPU ID (so
  CPU 0 is always first).  However, this makes it easier to add new types
  of event sources in the future and have them all clustered together
  instead of intertwined with threads.
- Python lists perform insertions at the tail much faster than insertions
  at the head.  For a trace that had a lot of events for a single event
  source, the constant insertions of new events to the head of the
  per-source event list caused a noticable slow down.  To compensate,
  append new events to the end of the list during parsing and then
  reverse the list prior to drawing.
- Somewhere in the tkinter internals the coordinates of a canvas are
  stored in a signed 32-bit integer.  As a result, if an the box for
  an event spans 2^31, it would actually end up having a negative
  X offset at one end.  The result was a single box that covered the
  entire event source.  Kris worked around this for some traces by
  bumping up the initial ticks/pixel ratio from 1 to 10.  However, a
  divisor of 10 can still be too small for large tracefiles (e.g.
  with 4 million entries).  Instead of hardcoding the initial scaling
  ratio, calculate it from the time span of the trace file.
- Add support for using the mouse wheel to scroll the graph window
  up and down.

 - Add a horrible bit of code to detect tsc differences between processors.
   This only works if there is no significant drift and all processors are
   running at the same frequency.  Fortunately, schedgraph traces on MP
   machines tend to cover less than a second so drift shouldn't be an issue.
 - KTRFile::synchstamp() iterates once over the whole list to determine the
   lowest tsc value and syncs adjusts all other values to match.  We assume
   that the first tick recorded on all cpus happened at the same instant to
   start with.
 - KTRFile::monostamp() iterates again over the whole file and checks for
   a cpu agnostic monotonically increasing clock.  If the time ever goes
   backwards the cpu responsible is adjusted further to fit.  This will
   make the possible incorrect delta between cpus as small as the shortest
   time between two events.  This time can be fairly large due to sched_lock
   essentially protecting all events.
 - KTRFile::checkstamp() now returns an adjusted timestamp.
 - StateEvent::draw() detects states that occur out of order in time and
   draws them as 0 pixels after printing a warning.
