Kernel 5.8 RC1 breaks the onboard DPAA network adapter of the AmigaOne X5000/20

Big picture http://www.skateman.nl/wp-content/uploa ... 234930.png

Reverting back to Alpha 4 made the DPAA network adapter working again.

Hi Skateman,

Thanks a lot for testing the RC1!

Strange thing with the DPAA ethernet. I didn’t find any DPAA changes between the alpha4 and the RC1. I only found one DPAA2 commit between the alpha4 and the RC1 but our X5000 has DPAA1. The kernel developers expect a bisect from us but I can’t do it alone because the DPAA ethernet has never worked reliable on my X5000/20 and X5000/40. We need to create about 13 kernels for the bisect. I can do that but I need you for testing them on your X5000. It’s a lot of work. What do you think? Shall we do it?

Thanks,
Christian

For me its key to have the onboard ethernet adapter working again.
I also think that most of us did not tried to unplug the inserted pci networkadapter so the X5K was using only its onboard adapter.
If thats the solution i dont know... but i wont revert back to using a pci nic.

That leaves me to the only possible option, and i am willing to test all kernels needed

I did it because MorphOS on my X5000/20 doesn't need an additional PCI network card. I successfully downloaded the RC1 with the onboard ethernet (p50x0eth.device:0) on MorphOS today and after unpacking the package I was able to copy the RC1 kernel to the Fienix-boot partition. Then I rebooted the X5000/20 and started Fienix with the RC1 successfully.

Screenshots:

I also tested the DPAA Ethernet with the stable kernel 5.7 and Darren's new cyrus-p5020.dtb on my X5000/20 but without any success.

I will compile the first test kernel tomorrow.

I see. This kernel needs the boot-v1.patch because of the boot issues at the beginning of the kernel 5.8 testing.

Please try it again with the following patched kernel: uImage-dpaa2
