Subject: [PATCH 0/3] firmware: arm_scmi: perf/cpufreq: Enable notification only if supported by platform
Date: Wed, 11 Jun 2025 15:52:42 +0800 [thread overview]
Message-ID: <20250611-scmi-perf-v1-0-df2b548ba77c@nxp.com> (raw)
PERFORMANCE_NOTIFY_LIMITS and PERFORMANCE_NOTIFY_LEVEL are optional
commands. If use these commands on platforms that not support the two,
there is error log:
SCMI Notifications - Failed to ENABLE events for key:13000008 !
scmi-cpufreq scmi_dev.4: failed to register for limits change notifier for domain 8
If platforms not support perf notification, saving some cpu cycles
by introducing notify_supported ops.
While at here, patch 1 is a typo fix when doing the patchset.
