This option enables sanity checks in s390 low-level entry code.
|
|
Some of these sanity checks may slow down kernel entries and
|
|
exits or otherwise impact performance.
|

|
|
If unsure, say N.

This option provides a debugging facility to inject certain artificial events
|
|
and instruction responses to the CIO layer of Linux kernel. The newly created
