[PATCH 0/6] target/arm: -cpu host/max KVM and HVF fixes


From: Peter Maydell
Subject: [PATCH 0/6] target/arm: -cpu host/max KVM and HVF fixes
Date: Fri, 4 Feb 2022 16:55:00 +0000

This patchset fixes various minor bugs in KVM and HVF
-cpu host and -cpu max:

(1) KVM -cpu max was incorrectly adding a 'sve-max-vq' property
that wouldn't work and which doesn't exist in KVM -cpu host

(2) HVF -cpu max was using all the TCG ID fields and thus
promising the guest more than the host CPU can actually do

(3) HVF -cpu host wasn't setting up the PAuth properties, so
it defaulted to not telling the guest about PAuth support

This series fixes (1) by moving the '-cpu host' code to
cpu64.c since it's aarch64-specific anyway, which lets us
reuse it from the '-cpu max' init function. It fixes
(2) and (3) mostly by making HVF use the same bits of code
that KVM does for -cpu max and PAuth.
