Kompiler og installer driver med kildekode

I denne KB tager vi X710 NIC som eksempel. Alle de andre Linux-kildekoder er ens.

Installere nødvendige pakker til kompilering.

[root@rhel87 ~]# yum groupinstall "Development Tools"
[root@rhel87 ~]# yum install kernel-devel-$(uname -r)

1. Download driveren fra Dells supportportal.
2. Udpak og hent kildekoden.

3. Kompiler driveren.

3 a. Problem: Hvis du har set følgende fejl, når kommandoen "make" køres

common.mk:82: *** Kernel header files not in any of the expected locations.
common.mk:83: *** Install the appropriate kernel development package, e.g.
common.mk:84: *** kernel-devel, for building kernel modules and try again.  Stop.

Sørg for, at pakken "kernedevel" med samme kerneversion installeret. (I første trin)

[root@rhel87 ~]# yum install kernel-devel-$(uname -r)

3b. Problem: Test driveren før installation. Hvis fejlen "Påkrævet nøgle ikke tilgængelig" vises, betyder det, at serveren har "Sikker opstart" aktiveret, hvilket ikke er tilladt at indlæse selvkompileret driver. Du kan starte op i BIOS for at deaktivere "Sikker opstart".

[root@rhel87 src]# modprobe -r i40e
[root@rhel87 src]# insmod ./i40e.ko
insmod: ERROR: could not insert module ./i40e.ko: Required key not available

4. Installer driveren på denne server.

[root@rhel87 src]# make install

5. Genstart serveren, hvorefter den nye driver indlæses automatisk efter opstart.


Yderligere:
Hvis du vil oprette RPM baseret på denne driver for at installere til de andre servere (skal være den samme kerneversion på destinationsserveren), skal du køre følgende kommando for at oprette rpm.

[root@rhel87 src]# cd ../..
[root@rhel87 base_driver]# ls -lh i40e-2.20.12.tar.gz
-rw-r--r-- 1 5714316 1049089 673K Jul 11  2022 i40e-2.20.12.tar.gz
[root@rhel87 base_driver]# rpmbuild -tb i40e-2.20.12.tar.gz
...skipped...
[root@rhel87 base_driver]# ls /root/rpmbuild/RPMS/x86_64/

Kopier rpm til destinationsserveren for at installere.
