this README lists and explains the possibilities of the vbtracetool tools
the file QUICKSTART may provide a more concise and direct route to your ends
vbtracetool
===========
Dependencies:
libpci
Building:
Run make
Running:
./vbtracetool [-d] [-l] [-r] [-g | -p | -s MODENUMBER | -w]
-d gives trace output *to stderr*. you'll want to redirect that.
-l gives IO logging *to stderr*. you'll want to redirect that.
-r forces use of the shadow ram bios image
-g gets the current display mode number (default)
-p posts the card. could induce several seconds of pants cacking with -d.
-s sets the given mode number
-w writes the bios image that would be executed by the other options *to stderr*
./postandrestore.bash [-d] [-l] [-r]
options as for vbtracetool
this shell script will run vbtracetool in such a way to do a POST
(which may be traced) and then restore the graphics mode (useful for fbcon)
try either of these in x and lose.
Bonus trace processor:
"./deloopify TRACENAME" will compact loops in your trace
Known issues:
see KNOWN_ISSUES file
Killing:
do not interrupt, once started -- you will likely earn yourself a hung machine
if you really really don't like what's happening, turn the power off
Culprit:
Stuart Bennett, using code and ideas from Matthew Garrett's libx86 and vbetool,
and the SciTech/Xorg x86emu emulator
