[PATCH 0/1] s390x:clp: implementing CLP immediate commands

Posted by Pierre Morel 2 years, 7 months ago

CLP immediate commands allow to query the Logical Processor
available on the machine and to check for a specific one.

I do not see any reason to not implement it.

The check for an immediate command is done on bit 0 of the RRF i3
field so let's implement a new clp_immediate_cmd() to handle CLP
immediate commands.

AFAIK only the basi processor, with Logical Processor Selector 0,
LPS==0, and the PCI processor, LPS==2, are currently available on
QEMU.
