Subject: [kvm-unit-tests PATCH 0/2] s390x: smp: Improve setup of additional cpus
Date: Wed, 11 Dec 2019 06:59:21 -0500 [thread overview]
Message-ID: <20191211115923.9191-1-frankja@linux.ibm.com> (raw)
Let's not use constants for the PSW mask and CRs, but set them from
input data or cpu 0.
Later on we could add functions that take a ptr for setting up CRs of
additional cpus, but for now using the CRs 0,1,7,13 from cpu 0 will at
least result in a working DAT environment.
