Subject: [PATCH 0/1] s390x:clp: implementing CLP immediate commands
Date: Fri, 17 Sep 2021 14:06:52 +0200 [thread overview]
Message-ID: <1631880413-20655-1-git-send-email-pmorel@linux.ibm.com> (raw)
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.
