Subject: [Qemu-devel] [QEMU-PPC] [PATCH] Use compat mode to set cpu features
Date: Thu, 16 Nov 2017 15:16:06 +1100	[thread overview]
Message-ID: <20171116041607.31852-1-sjitindarsingh@gmail.com> (raw)

Currently the compat mode isn't used when determining the values of the
ibm,arch-vec-5-platform-support and ibm,pa-features device tree nodes.

This means a POWER9 guest run in a prePOWER9 compat mode (or with a
prePOWER9 cpu model for TCG) will still use the radix mmu mode when
it shouldn't, because the capability is exposed through
ibm,arch-vec-5-platform-support.

The following patch fixes the setting of these properties by correctly
taking the compat mode into account.
