| |
Hi,
the following 2 patches enhance the markup_oops.pl script in two ways Patch 1: Add support for putting register values in the asm dump Patch 2: Add support for 64 bit X86
The output (on a 32 bit OS with a "make me oops" example module) looks like the pasted dump; for the instruction where the oops happened, as well as a few instructions before that where the dumper can determine the register value. the value is appended on said line.
