Revision e4f4fa00ebebe4b2c2f2ec2d27b7a2b77ce1c25f authored by David Gibson on 11 December 2017, 06:34:30 UTC, committed by Michael Roth on 06 February 2018, 00:53:54 UTC
Decimal Floating Point has been available on POWER7 and later (server) cpus. However, it can be disabled on the hypervisor, meaning that it's not available to guests. We currently handle this by conditionally advertising DFP support in the device tree depending on whether the guest CPU model supports it - which can also depend on what's allowed in the host for -cpu host. That can lead to confusion on migration, since host properties are silently affecting guest visible properties. This patch handles it by treating it as an optional capability for the pseries machine type.
