please don't forget to CC the list in your mails(or use 'Reply All').<br>
<br>
To enable debugging output for specific files, in this example undi.c,<br>
use the following command line to build gpxe:<br>
<br>
make bin/pnic.rom DEBUG=undi<br>
<br>
This line enables all DBG() and DBGC() output in undi.c. There are<br>
different debugging levels in gPXE, like DBG(level 1), DBG2(level 2),<br>
DBGP(level 4) and DBGIO(level 8). They are used like a bitfield.<br>
To enable DBG2() messages use DEBUG=undi:2. To enable DBG() and DBG2()<br>
messages use DEBUG=undi:3. You simply add the values of the debugging<br>
levels you want to enable. Separate multiple files with commas:<br>
DEBUG=rtl8139,undi:3<br>
<br>
Hope that helps<br>
