[Rocky Linux 10] How to build and install with DKMS #350

https://github.com/strongtz/i915-sriov-dkms/issues/350

silviuchingaru opened on Sep 24 · edited by silviuchingaru I build on Rocky Linux 10 host and guest with DKMS with steps below. I’ve disabled GVT because it won’t compile on Rocky 10 with it and, as far as I’ve understood, it is deprecated in newer kernels like 6.12.

My enviroment:

Rocky Linux release 10.0 (Red Quartz) Kernel 6.12.0-55.32.1.el10_0.x86_64 12th Gen Intel(R) Core(TM) i7-12700H PC: NUC12SNKi72 Version: M82271-501 On both, host or guest Run the following:

Install DKMS:

dnf install -y epel-release dnf install -y gcc make binutils dkms kernel-devel-$(uname -r) kernel-headers-$(uname -r) elfutils-libelf-devel perl git

Test installation:

dkms –version rpm -q kernel kernel-devel-$(uname -r)

cd /usr/local/src/ git clone https://github.com/strongtz/i915-sriov-dkms.git &&
cd i915-sriov-dkms &&
git checkout 2025.07.22

Get and apply the patch:

curl -LO https://github.com/user-attachments/files/22499662/0001-Rocky-10.patch git am 0001-Rocky-10.patch

Check status before:

dkms status

Build and install with dkms:

PKG=$(awk -F" ‘/^PACKAGE_NAME=/{print $2}’ dkms.conf) VER=$(awk -F" ‘/^PACKAGE_VERSION=/{print $2}’ dkms.conf) dkms add . dkms build $PKG/$VER dkms install $PKG/$VER

Check status after:

dkms status

Info on installed module, should say :

modinfo -n i915

lsmod | egrep ‘^(i915|drm_kms_helper|drm|snd_hda_intel)\b’ modprobe -r snd_hda_intel modprobe -r i915

Load builded module:

modprobe -v i915 modinfo -n i915

Check kernel messages:

dmesg -T

If everything is fine, rebuild init:

dracut -f On a guest machine: Poweroff

poweroff And from host passtrough one or more GPU VF to it with something like:

virsh edit

Inside ... section, probably right after </video>, add:

</source>

save, exist and start the guest

virsh start Check the guest kernel logs:
