Subject: [PATCH v2 2/5] target/arm: Allow setting 'pmu' only for host and max
Date: Tue, 16 Jul 2024 17:28:14 +0900 [thread overview]
Message-ID: <20240716-pmu-v2-2-f3e3e4b2d3d5@daynix.com> (raw)
In-Reply-To: <20240716-pmu-v2-0-f3e3e4b2d3d5@daynix.com>
Setting 'pmu' does not make sense for CPU types emulating physical
CPUs.
