Out of curiosity I went looking for the source of the Lowrisc Ethernet driver. I found a patch adding what appears to be this version at: Either way it would be useful for the commit comment to include an upstream source and version for this driver to make it easer to track changes. |
@stuartmenefy Thanks for the heads-up! Their new updated driver (from 2 weeks ago) has been pushed recently after I made that update. Their updated one should make our life easier, I'll test it and try to just use that and remove my changes/updates if it works fine. |

Please look at the checkpatch complaints as well. Some should be ignored but some (trailing whitespace, ...) do need fixing, please. |
[Andreas Korb: Upgrade to modern kernels and fix bugs
- Remove unneeded MMC driver
- Adapt from Linux kernel 5.1 to 6.19
- Fix compilation warnings
- Refactoring
- Fix re-enabling ethernet interface
(works now instead of saying interface is busy)

A defconfig is a combination of the current upstream CVA6-Linux [1] and CHERI Alliance's Linux that enables CHERI.

Currently still just testing after upgrading to the latest CVA6-Linux patches as @stuartmenefy suggested. The original patch has these whitespace errors, I'll look into it and let you know when this PR is ready for another review |
