Last time I talked to Thomas and others it wasn't "text only" but text
also in that you can just cat a debugfs file for simple tracing.  And I
totally agree with that.  If you don't trace too much that's absolutely
enough.  It's not enough for large traces on highly loaded enterprise
or high-end embedded systems or things like flight recorder tracing, but
for those requiring an external viewer is just fine.
