** ABSTRACT:
|
||||
**
|
||||
** This header provides generic debugging capabilities using printf.
|
||||
** All debugging can be compiled out by not defining the
|
||||
** KERNEL_DEBUG macro. In addition the amount of debug output is
|
||||
** defined by individual variables controlled by each subsystem
|
||||
** using this utility. Finally note that the two middle bytes of
|
||||
** the kern debug flags (bits 16 to 23) are free for individual
|
||||
** subsystems to use as they please (eg. define switches for
|
||||
** individual functions etc).
