From 87273151110b7736b34ae3e37ad778c28c36d643 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Tue, 26 Jun 2018 14:38:30 +0200 Subject: [PATCH] s390x/cpumodel: default enable bpb and ppa15 for z196 and later Most systems and host kernels provide the necessary building blocks for bpb and ppa15. We can reverse the logic and default enable those features, while still allowing to disable it via cpu model. So let us add bpb and ppa15 to z196 and later default CPU model for the qemu 3.0 machine. (like -cpu z13). Older machine types (e.g. s390-ccw-virtio-2.12) will retain the old value and not provide those bits in the default model.
