Raspberry Pi AXI PMU Driver Under Review For The Mainline Linux Kernel
Raspberry Pi AXI PMU Driver Under Review For The Mainline Linux Kernel Written by Michael Larabel in Raspberry Pi on 11 August 2026 at 08:00 AM EDT. Add A Comment One of the Raspberry Pi device drivers that has remained elusive from the mainline Linux kernel has been for the performance monitoring unit (PMU) for the Broadcom AXI on all Raspberry Pi 1 through Raspberry Pi 5 models. Thanks to the work of a Google engineer, there is a new effort working to get a mainline Linux driver for the Raspberry Pi AXI PMU.

Add A Comment One of the Raspberry Pi device drivers that has remained elusive from the mainline Linux kernel has been for the performance monitoring unit (PMU) for the Broadcom AXI on all Raspberry Pi 1 through Raspberry Pi 5 models. Thanks to the work of a Google engineer, there is a new effort working to get a mainline Linux driver for the Raspberry Pi AXI PMU. Ian Rogers of Google has been working to address the lack of a Linux perf-compatible PMU driver for the performance counters exposed by the Broadcom AXI on Raspberry Pi devices.
