from Tkinter import *
# To use:
# - Install the ports/x11-toolkits/py-tkinter package; e.g.
# portinstall x11-toolkits/py-tkinter package
# - Add KTR_SCHED to KTR_COMPILE and KTR_MASK in your KERNCONF; e.g.
# options KTR
# options KTR_ENTRIES=32768
# options KTR_COMPILE=(KTR_SCHED)
# options KTR_MASK=(KTR_SCHED)
# - It is encouraged to increase KTR_ENTRIES size to gather enough
# information for analysis; e.g.
# options KTR_ENTRIES=262144
# as 32768 entries may only correspond to a second or two of profiling
# data depending on your workload.
# - Rebuild kernel with proper changes to KERNCONF and boot new kernel.
# - Run your workload to be profiled.
# - While the workload is continuing (i.e. before it finishes), disable
# KTR tracing by setting 'sysctl debug.ktr.mask=0'. This is necessary
# to avoid a race condition while running ktrdump, i.e. the KTR ring buffer
# will cycle a bit while ktrdump runs, and this confuses schedgraph because
# the timestamps appear to go backwards at some point. Stopping KTR logging
# while the workload is still running is to avoid wasting log entries on
# "idle" time at the end.
# - Dump the trace to a file: 'ktrdump -ct > ktr.out'
# - Run the python script: 'python schedgraph.py ktr.out' optionally provide
# your cpu frequency in ghz: 'python schedgraph.py ktr.out 2.4'
#
# To do:
# Add a per-source summary display
# "Vertical rule" to help relate data in different rows
# Mouse-over popup of full thread/event/row label (currently truncated)
# More visible anchors for popup event windows
#
# BUGS: 1) Only 8 CPUs are supported, more CPUs require more choices of
# colours to represent them ;-)
