Subject: [PATCH v4 17/24] target/arm: Add ARMFault_UnsuppAtomicUpdate
Date: Mon, 10 Oct 2022 20:19:04 -0700 [thread overview]
Message-ID: <20221011031911.2408754-18-richard.henderson@linaro.org> (raw)
In-Reply-To: <20221011031911.2408754-1-richard.henderson@linaro.org>
This fault type is to be used with FEAT_HAFDBS when
the guest enables hw updates, but places the tables
in memory where atomic updates are unsupported.
Reviewed-by: Peter Maydell <peter.maydell@linaro.org>
