I haven't written a README yet because it's still very experimental. Actually I do have a draft README I should clean up... You should just be able to start an X server and run ./revenge, after the usual ./configure && make. You will need to be root or setup setuid for revenge as it needs access to /dev/mem. It will print the information to stdout. # startx & # ./revenge All it does is look at the ring head/tail before executing some GL commands (usually drawing a triangle) and checks the ring head/tail again afterwards. It then does and analyses the packets that were added to find out the register writes. It does not display the register names in a human readable format yet so you must instead use: grep -i 'f00' radeon_reg.h r300_reg.h. I plan to add rules-ng support and convert the header files into an XML database so that the register names can be printed in human readable format. I also don't analyze the indirect buffer's yet, but this should be trivial to add; it just needs some different shifts/masks on the packets. For now, you can use pretty_print_command_stream.tcl from glxtest (see DRI wiki) to print the indirect buffers, and it can (to a limited extent) display in human readable format. I also have to add support for disassembling fragment and vertex programs intelligently. So there is quite a bit of work still left to do before it's especially useful; you can use it now, but some manual work is required. I would appreciate any feedback from you, and I also don't mind answering other questions. :) You can see a (old) example of the output at http://z3ro.name/tmp/revenge_null_tri.diff. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
