i think perhaps i need to expound upon what i have a vision of. a kernel mode
console is just that: a console designed to run in kernel mode. it could have
built in commands to allow for quick and dirty examination of stuff (anything
really, like memory dumps) and a command processor for scripted stuff, but
the true power of it comes in when you issue a command that is not internal
to the console. it could run a special debugger, an application that installs
a probe, a memory monitor, etc., etc. in short it is not a debugger per-say,
but a "god mode" console for the linux kernel. that is what i had a vision
of. the executables it would run would necessarily be compiled for that.
again, i ask is that worth the time coding it?
