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. Sponsored by: Nokia - 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.

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
|
|
# Click to move.
|
|
# Hide rows
|
|
# "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 ;-)
