To check out and build:

svn checkout svn://svn.code.sf.net/p/procdbgunittest/code/trunk procdbgunittest-code

cd procdbgunittest-code

svn checkout svn://svn.code.sf.net/p/kerneldebugutil/code/trunk kerneldebugutil-code

svn checkout svn://svn.code.sf.net/p/procutils/code/trunk procutils-code

make

To install kernel modules:

make load (make unload to remove)

To dump the trace buffer:

cat /proc/kdebug/debug/trace

to add messages you can

echo "message" > /proc/kdebug/debug/trace

if you echo 1 > /proc/kdebug/debug_test/inject

you'll get a call tree.

You can echo 0 or 1 into /proc/kdebug/debug/indent so that the call tree will be shown without or with indentation.

The debug level for each unit is readable/settable in /proc/kdebug/debug/units/*
