Subject: [PATCH v4 08/12] target/arm: Restrict ARMv7 M-profile cpus to TCG accel
Date: Wed, 30 Sep 2020 00:43:51 +0200 [thread overview]
Message-ID: <20200929224355.1224017-9-philmd@redhat.com> (raw)
In-Reply-To: <20200929224355.1224017-1-philmd@redhat.com>
A KVM-only build won't be able to run M-profile cpus.
Only enable the following ARMv7 M-Profile CPUs when TCG is available:
- Cortex-M0
- Cortex-M3
- Cortex-M4
- Cortex-M33
We don't need to enforce CONFIG_ARM_V7M in default-configs because
all machines using a Cortex-M are already explicitly selected.
