I had to enable "use kernelmode debugger options when possible" to attatch to a program that kept giving me an error 87 failed to attatch. Is it possible to enable something like this for the memory view as well? When I toggle a break point it says it needs to attatch, but it doesn't attatch using the kernelmode debugger options so I get the error 87 and can't use breakpoints. Thanks!

the problem with my kernel debug routine is that I can't freeze threads and have to exit out of there quite fast to not slowdown the system.
Only other use it can have is for using it in the option to change registers on breakpoints, because it resumes the process anyhow. (planned for ce 5.2)

But thats the furthest you can go with it , untill I can figure out how to suspend a process from kernelmode

Hmm, perhaps injecting a code section that only does sleep(xxx) until a flag is set to true and then jump back to the original code with the original or modified registers.... interesting... got to look into that

I've managed to get the "change registers on this address" function to kernelmode as well, so no real debugger is needed anymore.

Next up single stepping. (got to investigate kernel mode APC's and the suspend mutex and suspend count in kthread)
