Hi,

is it somehow possible to use Dtrace for error injection in a kernel module?

Something like changing:
- function return value
-  value of a register

If not, can it be implemented?


I can do that via kmdb, but I need Dtrace for the time synchronization - chill() action.
I can not combine Dtrace & kmdb:

dtrace: failed to initialize dtrace: DTrace cannot be used when kernel debugger is active

Thanks,
Pavel
