Firmware requirement
The driver-family needs firmware not in linux-firmware; check which files your device requires. This is a driver-family list, not a per-device requirement. Optional features and other chips may use different files. Presence is checked against linux-firmware WHENCE File and Link records, including patterns.
| Firmware | Manifest check |
|---|---|
3826.arm | Not listed in WHENCE — external firmware may be needed |
3826.eeprom | Not listed in WHENCE — external firmware may be needed |
isl3886pci | Not listed in WHENCE — external firmware may be needed |
