** Description changed: + == 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. + + Corresponding configs like CONFIG_ARCH_MVEBU and CONFIG_ARCH_MULTI_V7 + need to be enabled as well to meet the dependency requirement. + + CONFIG_CRYPTO_DEV_SAFEXCEL and CONFIG_PCI_AARDVARK are disabled + explicitly to avoid interactive dialogues when building the kernel. + + == Test == + A test kernel for Disco ARM64 could be found here: + https://people.canonical.com/~phlin/kernel/lp-1835054-mvpp2/ + + User has confirmed that the patched kernel can fix this missing driver + issue. + + == Regression Potential == + Low, this patch just make this driver to be built as a module, and we already have this enabled 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.
