1What: /sys/bus/pci/devices/<BDF>/vendor_reset 2Date: 22-Jul-2026 3KernelVersion: 6.17 4Contact: linux-bluetooth@vger.kernel.org 5Description: This read-write attribute allows userspace to trigger a 6 Product Level Device Reset (PLDR) on Intel PCIe Bluetooth 7 controllers. Reading the attribute displays the supported 8 reset type. Writing integer 0 triggers PLDR. Any other 9 input is rejected with -EINVAL. 10 11 PLDR resets the entire on-chip platform shared between 12 Bluetooth and WiFi. This means any driver attached to 13 the WiFi device that shares hardware with this Bluetooth 14 device will be released, the platform will be reset, and 15 both the Bluetooth and WiFi devices will be re-probed. 16
