CentOS 8 and deprecated drivers

Hi All,

I know that most of you haven't checked RHEL8 release notes, but I have noticed that some drivers will be removed or just not supported.
Does anyone thought about leaving some of the stuff in CentOS ?

In my case that will be the e1000 ,but who knows - I haven't checked it all.

Once it's out and CentOS starts the rebuild process, you can always request that things be enabled in the CentOS Plus kernel. Though e1000 is listed as removed, the newer and more widely used e1000e is still there and still supported.

For reference (and until it breaks!), the relevant doc is on this link

As far as I know e1000e doesn't support legacy PCI-based NICs and I have no other option but to request e1000 module once CentOS8 is here.
I hve noticed that RHEL 8.0 beta still has it, but I'm not sure if they will completely remove it in the public release or just warn it is not supported.

There is also an option to buy another PCI-based NIC that is still supported, if it turns out your NIC won't be supported.

There is no overlap of the PCI vendor/device ids supported by the two modules.

I have checked the web and e1000e supports PCIe - based NICs , while e1000 supports the PCI-based (old legacy ports) NICs.
I'm pretty sure I'm not the only one running e1000 NICs (which were recently bought).

Of course, I have the option to play around and build the module from source , but I will keep that as last resort.

You could always ask ELRepo if they aim to fill the gap. They already have kmod-e100, kmod-ixgb and ixgbe packages for el7.

For now, I will wait for RHEL8 release and check the situation there.
At least there are 2 options if Red Hat completely removed the module:
1. Check in the forum . I guess if a lot of people still need the module - it will be addded in CentOS
2. If not - external repos might add it.

Last option is compilation from source, but I'd rather not to use that.

The CentOS 8 kernel will match the RHEL 8 one exactly except for branding etc. The same options and modules will be enabled. There will not be any additional modules enabled that are not enabled in the RHEL version.

The CentOS Plus kernel is different and can be changed.

ELRepo will no doubt be packaging things for el8 though I've not seen that definitely in writing. Who knows, perhaps one of the ELRepo people might read this and comment... :-)

There is a good sign that indicates ELRepo will be building packages for EL8:

Some kmods are there. :)
