Subject: [PATCH v1 07/13] KVM: arm64: Add config register bit definitions
Date: Tue, 8 Jun 2021 15:11:35 +0100 [thread overview]
Message-ID: <20210608141141.997398-8-tabba@google.com> (raw)
In-Reply-To: <20210608141141.997398-1-tabba@google.com>
Add hardware configuration register bit definitions for HCR_EL2
and MDCR_EL2. Future patches toggle these hyp configuration
register bits to trap on certain accesses.
No functional change intended.
