Subject: [PATCH v3 04/17] arm64/sysreg: Add missing system instruction definitions for FGT
Date: Thu, 14 Dec 2023 10:01:44 +0000 [thread overview]
Message-ID: <20231214100158.2305400-5-tabba@google.com> (raw)
In-Reply-To: <20231214100158.2305400-1-tabba@google.com>
Add the definitions of missing system instructions that are
trappable by fine grain traps. The definitions are based on
DDI0602 2023-09.
