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.
- Parameterize the layout with X_ and Y_ defines that determine the sizes
of various things.
- Remove unnecessary tags.
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.
Cons25 doesn't seem to use a straight 1:1 mapping to the ANSI colors,
but uses the same color numbers as at least used by syscons on i386. I
suspect if you change the definitions on a different architecture,
things may break? Not sure.
Add a small array to convert syscons-style color codes to ANSI
equivalents, which are used by libteken internally. I didn't notice this
bug, because I only tested my code with black, white and green, all of
them shared the same numbers.
It turns out I forgot to implement two escape sequences that allows the
user to change the default foreground and background colors. I thought
they were implemented by syscons itself, but vidcontrol just generates
some escape sequences, which get interpreted by the terminal emulator.

quoth the README:
I have been running -current on my laptop since before FreeBSD 2.0 was
released and along the way developed this little trick to making the
task easier.
sysbuild.sh is a way to build a new FreeBSD system on a computer from
a specification, while leaving the current installation intact.
sysbuild.sh assume you have two partitions that can hold your rootfs
and can be booted, and roughly speaking, all it does is build a new
system into the one you don't use, from the one you do use.
A partition named /freebsd is assumed to be part of your layout, and
that is where the sources and ports will be found.
If you know how nanobsd works, you will find a lot of similarity.
sets up a fake buffered FILE and then effectively calls itself
recursively. Unfortunately, gcc doesn't know how to do tail call
elimination in this case, and actually makes things worse by
inlining __sbprintf(). This means that f[w]printf() to stderr was
allocating about 5k of stack on 64-bit platforms, much of which was
never used.
I've reorganized things to eliminate the waste. In addition to saving
some stack space, this improves performance in my tests by anywhere
from 5% to 17% (depending on the test) when -fstack-protector is
enabled. I found no statistically significant performance difference
when stack protection is turned off. (The tests redirected stderr to
/dev/null.)
The teken library already supports UTF-8 handling and xterm emulation,
but we have reasons to disable this right now. Because we should make it
easy and interesting for people to experiment with these features, allow
them to be set in kernel configuration files.
Before this commit we had a flag called `TEKEN_CONS25' to enable
cons25-style emulation. I'm calling it the opposite now, `TEKEN_XTERM',
because we want to enable it in kernel configuration files explicitly.

Pseudo-terminals allocated with posix_openpt(2) will have more slashes
in their path names than comsat(8) allows, so allow slashes when the
character device name starts with "pts/".
This patch is loosely based on NetBSD's changes, revision 1.33. Because
it also included the changes to fork(), I imported them here as well.
Maybe we could import even more fixes from the other BSD's?

displaying sources.
- Add functions to the main SchedGraph to facilitate source hiding. The
source is simply moved off screen and all other sources are moved to
compensate.
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.
with src/tools/sched/schedgraph.py. This allows developers to quickly
create a graphical view of ktr data for any resource in the system.
- Add sched_tdname() and the pcpu field 'name' for quickly and uniformly
identifying records associated with a thread or cpu.
- Reimplement the KTR_SCHED traces using the new generic facility.
