Subject: [kvm-unit-tests PATCH 0/2] s390x: Improve architectural compliance for diag308
Date: Tue, 5 Nov 2019 11:28:26 -0500 [thread overview]
Message-ID: <20191105162828.2490-1-frankja@linux.ibm.com> (raw)
When testing diag308 subcodes 0/1 on lpar with virtual mem set up, I
experienced spec PGMs and addressing PGMs due to the tests not setting
short psw bit 12 and leaving the DAT bit on.
The problem was not found under KVM/QEMU, because Qemu just ignores
all cpu mask bits... I'm working on a fix for that too.

s390x: Add CR save area
s390x: Remove DAT and add short indication psw bits on diag308 reset
