Linux 6.18 To Support The Red & Green Status LEDs On QNAP NAS Devices

Written by Michael Larabel in Hardware on 7 October 2025 at 05:54 AM EDT. 5 Comments
The LED subsystem updates don't tend to be too exciting each kernel cycle but for those with QNAP network attached storage (NAS) devices and wanting to run the mainline kernel, now you can have working red and green status LEDs.

For those with QNAP NAS hardware, the Linux 6.18 kernel will enable the red/green status LEDs to be correctly operated. The status LEDs are connected to QNAP's Microcontroller Unit (MCU) that can now be controlled from the mainline Linux kernel using the leds-qnap-mcu driver.

That is the main highlight of the LEDs update for Linux 6.18. There is also the new S31FL3236A LED driver as the other new LED hardware support for Linux 6.18.
