Changelog

The following sections provide detailed lists of changes by component.

Applications

nRF Desktop

• Added the CONFIG_DESKTOP_CPU_LOAD_EVENT Kconfig option. This option enables the cpu_load_event.

• Updated the CPU measurement module to allow emitting the measured CPU load directly through the nRF Profiler API (CONFIG_DESKTOP_CPU_MEAS_RESULT_NRF_PROFILER), which minimizes the impact on the measured CPU load. The option is enabled by default if the nRF Profiler (CONFIG_NRF_PROFILER) is enabled.

  Submitting CPU load as a cpu_load_event is controlled through the newly introduced CONFIG_DESKTOP_CPU_MEAS_RESULT_EVENT Kconfig option. The feature is disabled by default if the CONFIG_DESKTOP_CPU_MEAS_RESULT_NRF_PROFILER option is enabled.

Host tools

No changes since the latest HID Add-on release.

Libraries and subsystems

Common Application Framework (CAF) extensions

• Added the CAF: Buttons module (ISR) module (CONFIG_CAF_BUTTONS_ISR), an alternative to CAF: Buttons module that emits a button_event with minimal latency using GPIO interrupts. The module supports directly connected buttons, optional power management integration, and an optional dedicated workqueue for debouncing (CONFIG_CAF_BUTTONS_WQ).
