Hi,
After installing Centos8.2 on Marvell CN9132 based platform I noticed that compared to altarch7-aarch64 support the Marvell MVPP2 NIC support was dropped.
In order to enable it we would need to add CONFIG_ARCH_MVEBU=y CONFIG_MVPP2=m to the SOURCES/kernel-aarch64.config & SOURCES/kernel-aarch64-debug.config
What are the steps to achieve that? Centos altarch7 had a described procedure for submitting the kernel patches, but that seems to be changed in the new distro version.
Best regards, Marcin

The difference is exatly there, in the altarch. For 8.x, aarch64 is an official RH Arch, so we use the same configs that they provide. The only way I see is though the proper Stream channels, I mean filing an issue in bugzilla.redhat.com under CentOS Stream, providing the patch and seeing where that goes. It would be interesting to check in the 8.x release notes if this driver wasn't specifically deprecated. If it were x86_64, we could add it to the plus kernel, but I think we don't build it for aarch64.
Wrt altarch kernels (5.4.x at the moment), we use the same configs for 7.x and 8.x, so hopefully we'll be able to build and release them soon for 8.x too.

Thanks, the driver is not listed as deprecated in the RHEL release notes of course. I created a bug https://bugzilla.redhat.com/show_bug.cgi?id=1894173 - let's see where it takes us.
