Research direction

Search the Raspberry Pi defconfig files for CONFIG_CAN_KVASER_PCIEFD and CONFIG_CAN_KVASER_USB, then compare nearby CAN driver settings. Enable both symbols as modules and verify the resulting configuration and Kvaser device behavior with ip link show | grep can on the stated Raspberry Pi hardware.

Written by the indexing model from the issue text.

Description

Describe the bug

Please enable the Kvaser CAN interface modules, kvaser_usb and kvaser_pciefd, in the Raspberry Pi defconfigs:

CONFIG_CAN_KVASER_PCIEFD=m
CONFIG_CAN_KVASER_USB=m

There are numerous solutions and proof-of-concepts where a Raspberry Pi is combined with Kvaser USB CAN interfaces. Additionally, various setups using Kvaser PCIe or M.2 cards with the CM4 or Raspberry Pi 5 are becoming increasingly popular.

Steps to reproduce the behaviour

Plug-in Kvaser USB device or Kvaser PCIe device.

ip link show | grep can
