Title:
Enable Armada SOCs and MVPP2 NIC driver for disco/generic arm64
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Disco:
Fix Released
Status in linux source package in Eoan:
Fix Released
Bug description:
== SRU Justification ==
The mvpp2 is a driver for network controllers(s) in Marvell SOCs,
particularly Armada 8040.
However this driver was neither enabled as a module or a built-in for
Disco arm64.
== Fix ==
Just like what we did for armhf, set CONFIG_MVPP2 to "m" for arm64 can
solve this problem.
We need to enable the Armada SOCs support (CONFIG_ARCH_MVEBU) as well
to meet the dependency requirement.
Other configs were added by the updateconfigs process.
== Test ==
A test kernel for Disco ARM64 could be found here:
https://people.canonical.com/~phlin/kernel/lp-1835054-mvpp2/V2/
User has confirmed that the V1 kernel can fix this missing driver
issue (V2 is just with CONFIG_ARCH_MULTI_V7 dropped and some configs
added explicitly, I have it tested on an ARM64 node, the mvpp2 module
can be loaded without any issue).
== Regression Potential ==
Low, this patch just enable the Armada SOCs and make this mvpp2 driver
to be built as a module on ARM64, and we already have those for armhf.
== Original Bug Report ==
At least in Ubuntu 19.04, the arm64 kernel (linux-image-5.0.0) is not
building CONFIG_MVPP2 (depends on CONFIG_ARCH_MVEBU) - a driver for
network controllers(s) in Marvell SOCs, particularly Armada 8040 -
neither as a module or a built-in:
$ uname -m
aarch64
$ grep MVPP2 /boot/config-5.0.0-20-generic
$
It makes very hard (and impossible for non-advanced users) to install
and use Ubuntu on the Macchiatobin board (http://macchiatobin.net/) -
a reasonably priced and performant server/mini-desktop platform.
Could it be added, please, and the installer image re-generated.
