Subject: [PATCH 0/2] kvm/arm64: unimplemented sysreg improvements
Date: Thu, 5 Dec 2019 18:06:50 +0000 [thread overview]
Message-ID: <20191205180652.18671-1-mark.rutland@arm.com> (raw)
While testing some other patches, I realised that KVM's logging of
trapped sysreg accesses can log inconsistent information, and this is
arguably unnecessary for IMPLEMENTATION DEFINED system registers.
This patches fix that up, ensureing that logged information is
consistent, and avoiding logging for IMPLEMENTATION DEFINED registers.
Mark.
