Kernel 5.6

[daz]

Skateman,

Could you please test the RC4-2 with the DPAA Ethernet as well?

Thanks,
Christian

RC4-2 Tested and broke the DPAA Ethernet functionality. The adapter does not get an IP address. Seems like link negotiation is not working. Reverted back to RC4 and posting this with a working DPAA Ethernet adapter

The IOMMU is breaking the DPAA, I've suspected this for a while. I've looked but there is no easy way to add the required code to fix it.

The fixes we need have been pushed to the U-Boot tree, and the iommu_domain structure in the kernel (needed for IOMMU) has been changed. We need Matthew to get U-Boot updated to the latest version.

The more people who ask the better,.
Regards
Darren

Hi,

Digging through my Log files i found this:

With kernel RC4-2 this seems to happen (see log below), and does not with kernel RC4. RC4 kernel is working fine with DPAA Ethernet and U-boot version Molsen 2018-10-05

Hi All,

I released the RC5 of kernel 5.6 for the X1000 and X5000 today.

New:

• Linux 5.6-rc5 Kernel Released -- phoronix.com
• X5000/40: Device Tree Blobs (dtb) with DPAA Ethernet support for testing (cyrus_p5040_eth_poweroff.dtb + cyrus_p5040_eth_poweroff-2_Fmans.dtb)
• PowerPC fixes 5.6-4
• 5.6-rc5 announcement
• Linux Git log
• Phoronix articles, reviews and news stories covering Linux 5.6

Download: linux-image-5.6-rc5-X1000_X5000.tar.gz

Screenshot:



Please test the kernels.

Thanks,
Christian

Kernel 5.6 RC5 is running great on the AmigaOne X5000 with working DPAA Ethernet adapter!

Had finally an opportunity to test RC4/RC5 with the onboard ethernet... If I start Linux (Fienix or Ubuntu) with the onboard ethernet socket connected to internet (via optical fiber modem), there is no connection created. But if I then unplug and replug the ethernet cable, net connection is created and seems also to work. I wonder what can cause this kind of peculiarity...?

PS. here is what dmesg gives:

Hi,

I have seen this behavior before. It takes a moment for the adapter to get his ip address by DHCP.
Can you reboot your X5K and wait a while to see if the adapter gets his IP address automaticly by DHCP?

I let it wait for a half an hour but it did not get connection. My RTL card does not have similar problems, and with AmigaOS both adapters get their address without delays.

[Skateman]

I could be more specific sorry... waiting a while was based on not more than 30 seconds.

The only difference i have compared to you is that i dont have any internal pci adapters anymore..

Thank you very much for testing the RC5!

Interesting! Thanks a lot for testing!
