Intel Wi-Fi Ax201 driver

[TrevorH]

You need kernel-ml-devel to match kernel-ml not kernel-devel.

Thank you for the reply Trevor. I am not savvy enough to figure this out!

I installed the kernel-ml-devel package with this command:

Code: Select all

yum --enablerepo=elrepo-kernel install kernel-ml-devel

If we launch VMWare Workstation its asking about a kernel module updater. Do you have any idea?

[TrevorH]

How did VMWare get into this? If it's a VM then it doesn't want or need the AX201 driver in the VM, it needs it on the host and then the VM "sees" a normal wired ethernet card. That's unless you use a VMWare thing to attach the physical card to that particular VM in passthrough mode.

My guess is that VMWare wants to rebuild its kernel modules for the elrepo kernel on the host. And this now requires the devtoolset-9 compiler, because the system compiler is already too old for recent kernels and elrepo therefore builds their kernels with devtoolset-9.

Trevor,
We have a batch of Dell Latitude 5411's which the developers want CentOS 7 installed. CentOS 7 would not see the NIC or the wifi adapter. Thats why we had to use the elrepo kernel. However, using the elrepo kernel breaks VMWare Workstation and it will not launch.
If we flip back to the standard kernel, VMWare Workstation launches with no issue but then wifi does not work. That is our dilemma.

[TrevorH]

So install the correct kernel-ml-devel to match the running kernel-ml.

I appreciate the reply.
I'm just not familiar enough with Linux to know what I need to get this going!

If I have this kernel: 5.10.6-1.el7.elrepo.x86_64

I only see the 5.10.7 and 5.10.8 kernel-ml-devel packages.

Code: Select all

What is the best way to match up the kernel-ml and kernel-ml-devel packages so VMWare Workstation will launch? As it is now, if I launch VMware under the elrepo kernel, I see this error:

Your running kernel has to match the -devel package that you have installed exactly. So if you are using kernel-ml, first `yum update kernel\*` then `yum install kernel-ml-devel` then reboot into the newly installed kernel and then try to do your build. It does also appear that you will need to install gcc and that it says it wants 9.3.1 and for that you will need to install

devtoolset-9-gcc.x86_64 9.3.1-2.el7 centos-sclo-rh

from the SCL repo.
