37 # - Install the ports/x11-toolkits/py-tkinter package; e.g.
38 #	pkg install x11-toolkits/py-tkinter
39 # - Add KTR_SCHED to KTR_COMPILE and KTR_MASK in your KERNCONF; e.g.
44 # - It is encouraged to increase KTR_ENTRIES size to gather enough
49 # - Rebuild kernel with proper changes to KERNCONF and boot new kernel.
50 # - Run your workload to be profiled.
51 # - While the workload is continuing (i.e. before it finishes), disable
58 # - Dump the trace to a file: 'ktrdump -ct > ktr.out'
59 # - Alternatively, use schedgraph.d script in this directory for getting
61 # - Run the python script: 'python schedgraph.py ktr.out' optionally provide
65 # Add a per-source summary display
67 # Mouse-over popup of full thread/event/row label (currently truncated)
71 #          colours to represent them ;-)
