I assume you meant "shouldn't".
I haven't yet integrated dynamic debug into my daily workflow.
Last time I looked at it, it was a bit bothersome to use because I
needed to lookup exact line numbers to trigger useful information. And
those line numbers constantly keep changing as I work on the driver,
so it was a bit painful to script. Not to mention the syntax to frob
the correct files in debugfs to enable this functionality.
As opposed to this, adding the following to the makefile is so easy. :-)
CFLAGS_tsens-common.o := -DDEBUG
Perhaps I am using it all wrong? How would I go about using dynamic
debug instead of this patch?
