What: /sys/bus/pci/devices//vendor_reset Date: 22-Jul-2026 KernelVersion: 6.17 Contact: linux-bluetooth@vger.kernel.org Description: This read-write attribute allows userspace to trigger a Product Level Device Reset (PLDR) on Intel PCIe Bluetooth controllers. Reading the attribute displays the supported reset type. Writing integer 0 triggers PLDR. Any other input is rejected with -EINVAL. PLDR resets the entire on-chip platform shared between Bluetooth and WiFi. This means any driver attached to the WiFi device that shares hardware with this Bluetooth device will be released, the platform will be reset, and both the Bluetooth and WiFi devices will be re-probed.
