Only compile dprintf/vdprintf if DEBUG_PORT is defined

2012-07-19T15:42:32+00:00

We really, really don't want to accidentally spew output to a debug
port in production, so make it obligatory to define DEBUG_PORT or
DEBUG_STDIO in order for the debugging code to be compiled in.  Since
DEBUG_STDIO just turns the debugging code into stdio references, we
only need to compile the code for the DEBUG_PORT case.

Add a commented-out line to mk/devel.mk to make it easier for users.

enabled.

dprintf: fix uninitialized pointer; return void

2009-11-20T00:52:11+00:00

Fix an uninitialized pointer bug; return void rather than returning
int like normal printfs... if we're depending on the return value of a
debugging function we're screwed when debugging is disabled.

dprintf: a generic debug-to-serial infrastructure

2009-11-19T19:10:00+00:00

Actually provide real infrastructure for debug-to-serial.  Very
useful when debugging fullscreen applications, especially under an
emulator like Qemu.
