Subject: s390x: Return specification exception for unimplemented diag 308
|
||
|
|
subcodes
|
||
|
|
|
||
|
|
The architecture specifies specification exceptions for all
|
||
|
|
unavailable subcodes.
|
||
|
|
|
||
|
|
The presence of subcodes is indicated by checking some query subcode.
|
||
|
|
For example 6 will indicate that 3-6 are available. So future systems
|
||
|
|
might call new subcodes to check for new features. This should not
|
||
|
|
trigger a hw error, instead we return the architectured specification
|
||
|
|
exception.
