DPAA Ethernet traffice troubles with Linux kernel

Hi linux devs,

Like mentioned in this thread
https://lists.ozlabs.org/pipermail/linuxppc-dev/2018-January/167630.html
i also experience the exact same issues.
I am also trying to find out why the network traffic is not flowing
the way it should (out for example ).

My linux knowledge is very basic but i hope i can contribute anyway.

I am using the AmigaOne X5000 with a P5020
Most detailed technical information regarding this issue can be found
in the Thread by Jamie Krueger mentioned above.

In this screenshot, the ETH0 and ETH1 seem up and running (probed) ..
even due to the FSL_DPAA_MAC error messages that DMESG shows.

http://www.skateman.nl/wp-content/uploads/2018/01/Screenshot-at-2018-01-08-22_16_28.png

I was able to use some tooling like ETHTOOL to adjust some settings
and check if the interface responded. This all seems fine.

Hope that someone can find a fix, so the Ethernet adapter can be used.

Thanks!!

Hi All,

I compiled the RC8 of kernel 4.15 with Joakim's patch for the AmigaOne X5000 today. Many thanks to Joakim for the mdio patch.

Please test it on your X5000.

Thanks,
Christian

Hi,

Please use text logs instead of pictures next time, it's easier to read.
The errors you see are related to missing MAC addresses for the unused
interfaces, you can ignore these are they are not relevant for the issue
you encounter. Normally the unused interfaces should have status disabled
in the device tree but there is not a big deal if they fail like that.
As I've advised Jamie on the other thread, please try to connect the device
back 2 back to a known good machine and determine what is broken - Rx/Tx?
Is there another software version that does work on these machines?

Hi, just saw this and thought of a small patch I just wrote for mdio bus, o idea
if it is relevant but here goes:

Hi All,

I have been testing with the rc8 kernel as Christian sugested.

At this moment still the same issues..

Here some of my finding...

A dump of dmesg regarding the FSL_DPAA:

Hi All,

I compiled the RC8 of kernel 4.15 with Joakim's patch for the AmigaOne
X5000 today. Many thanks to Joakim for the mdio patch.

Download: http://www.xenosoft.de/uImage-4.15-rc8_with_mdio_patch.tar.gz

Please test it on your X5000.

Thanks,
Christian

Hi,

Please use text logs instead of pictures next time, it's easier to
read.
The errors you see are related to missing MAC addresses for the unused
interfaces, you can ignore these are they are not relevant for the
issue
you encounter. Normally the unused interfaces should have status
disabled
in the device tree but there is not a big deal if they fail like that.
As I've advised Jamie on the other thread, please try to connect the
device
back 2 back to a known good machine and determine what is broken -
Rx/Tx?
Is there another software version that does work on these machines?

Hi Joakim

You appear to be using an old kernel. Take a look at:

commit 95f566de0269a0c59fd6a737a147731302136429
Author: Madalin Bucur [off-list ref]
Date:   Tue Jan 9 14:43:34 2018 +0200

    of_mdio: avoid MDIO bus removal when a PHY is missing
    
    If one of the child devices is missing the of_mdiobus_register_phy()
    call will return -ENODEV. When a missing device is encountered the
    registration of the remaining PHYs is stopped and the MDIO bus will
    fail to register. Propagate all errors except ENODEV to avoid it.

Hi Andrew,

From another thread[1] on the same topic:

I am not sure what PHY hardware/configuration you are using on the
DS and RDB platforms, but I can confirm that AmigaONE X5000/20
(Cyrus Motherboard with p5020 SoC), has dTSEC 4 and dTSEC 5
wired to two Micrel KSZ9021RN Gigabit Ethernet PHYs, using the
RGMII protocol.

Hi,

I have been looking deeper into my wireshark packet captures and found
something that could be helpfull.

I can see that the Ethernet NICS at least do something. ARP BROADCAST
traffic is seen.
But i also found some packets...which have LG BITs set to 1 .. when i think
0 should be the correct value..

This has something to do with the MAC adresses being non Authorative.. and
since whe can use Uboot and choose any Mac addr we want, this could make
sense.. More info about this
https://osqa-ask.wireshark.org/questions/59761/oui-lookup-tool-does-not-recognize-local-addresses

Logs like these appear: not the original.

.... ..1. .... .... .... .... = LG bit: Locally administered address (this
is NOT the factory default)
.... ...1 .... .... .... .... = IG bit: Group address (multicast/broadcast)


Will try to get the picture more clear... but think about this..

Hi Joakim

You appear to be using an old kernel. Take a look at:

Not really, I am using 4.14.x and I don't think that is old. Seems like
this
patch hasn't been sent to 4.14.x.

I wonder if I might be missing something else, we just moved to 4.14 and

Hi Joakim

You appear to be using an old kernel. Take a look at:

Not really, I am using 4.14.x and I don't think that is old. Seems like
this
patch hasn't been sent to 4.14.x.

I wonder if I might be missing something else, we just moved to 4.14 and
notic that all
our fixed PHYs are non functioning:

Hi,

I have been looking deeper into my wireshark packet captures and found
something that could be helpfull.

I can see using wireshark that the Ethernet NIC at least does something.
ARP BROADCAST traffic is seen.
But i also found some packets...which have LG BITs set to 1 .. when i think
0 should be the correct value..

This has something to do with the MAC adresses being locally administered
.. and since whe can use Uboot and choose any Mac addr we want, this could
make sense..

These types of Logs also apear in my Wireshark Capture files... ( these are
not my org. logs)

*"the first 3 octets/first-half of a MAC-48/EUI-48 Address, correspond to
the OUI (e.g.: MAC = 06:00:00:xx:xx:xx, OUI = 06:00:00), and the 2nd least
significant bit of its first octet is used to differentiate "Universally"
and "Locally" administered addresses). In other words, if we convert 06
(Hex) to 00000110 (Binary), we can see that the U/L bit is set to one,
which means that it a locally administered address.*

Development for 4.14 stopped somewhere around the beginning of
September. So there has been over 4 months of work since then.  We are

current stable version. But when reporting bugs, please let is know if
the latest version of the network kernel,
it://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git has
the issue.

Seems like this patch hasn't been sent to 4.14.x.

If it fixes a bug for you, please request the fix is added to stable.

You cannot just flip this bit. Universally administered addresses are
allocated by the IEEE. You need to purchase them from the IEEE.
Locally administered MAC addresses you can use, and any sane DHCP
server should work with them.

This also does not fit with mii-tool -R observation.

     Andrew

This makes me really start to wonder if the mainboard producer Varisys/AEON
has Purchased MAC`s for these boards at IEEE

Uboot system info gives for both MAC adresses the value NULL ... and i have
checked the mainboard for any stickers regarding the MAC adresses but there
is none..

I also tried to just create a ethaddr, eth1addr and eth2addr as mention on
the Wiki..but no luck

After using the new compiled 4.14 rc8 kernel without PAMU support posted by
Christian Zigotzky the X5000 can use the Network interface with some minor
issues.

I had to give the Eth0 a manual IP due to not responding on DHCP requests.

I can ping my Gateway, and even DNS queries work..

But when i start Netsurf (or generate to much packets)... all traffic
dies.... due to No buffer space available..

A workaround to keep Eth0 alive a bit longer.... is the following command

That doesn't work really, having users to hit the bug, debug it, fix it
and then
find it fixed already in upstream, then specifically request it to be
backported to stable.
I don't need this fix to be backported, already got it. Someone else might
though.

I would be interested in bug fixes upstream which fixes:

libphy: Freescale XGMAC MDIO Bus: probed

The "someone else might though" is a big point of asking for it to
added to stable. The other reason is it means one less patch you need
to maintain in your build.

I would be interested in bug fixes upstream which fixes:

Did you try upstream? Does it give the same errors?

Did you try upstream? Does it give the same errors?

commit 4d8ee1935bcd666360311dfdadeee235d682d69a
Author: Florian Fainelli [off-list ref]
Date: Tue Aug 22 15:24:47 2017 -0700
fsl/man: Inherit parent device and of_node

and was later addressed by this patch set:

http://patchwork.ozlabs.org/project/netdev/list/?series=8462&state=*

Even with these errors printed, all is working fine, it's just the
second probing that fails. Adding the latter patches or reverting
the one above makes the errors prints dissapear.

Looking at the above patch seriers I see it is in state Accepted and has been there
since 2017-10-16
That seems like a awful long to wait in before getting into Linux, is there something
holding these patches back ?

They are in Linux, have been since October 16th. But at the moment,
they are only in v4.15, not v4.14.

These patches probably don't fit the stable rules, for getting them
added to v4.14.

https://github.com/torvalds/linux/blob/master/Documentation/process/stable-kernel-rules.rst

What is needed is a minimal fix. Or just wait until Sunday, when there
is a good chance v4.15 will be released.

For those interested... i have recorded a video of my X5000 DPAA Ethernet,
and the weird problems..
In this Video i am also transfering hundereds of megabytes from my NAS to
the X5000.
You will also see pings die... mostly after the 12th packet and giving the
no buffer space error..
Hopefully someone might have a clue about what is happening.

Hello,

The PA Semi PWRficient Gigabit Ethernet doesn't work anymore since the first networking updates [1] for the kernel 4.16.

I figured out that the problematic code is in the mdio bus changes of the networking updates. [1]

I found the problematic code in the file 'drivers/net/phy/mdio_bus.c'. I created a patch which solves the problem with the PA Semi PWRficient Gigabit Ethernet. (attached)

Could you please check the changes in the file 'drivers/net/phy/mdio_bus.c'?

Thanks,
Christian

-38 is ENOSYS.

So i think you don't have GPIOLIB enabled. Hence you are hitting

http://elixir.free-electrons.com/linux/latest/source/include/linux/gpio/consumer.h#L470

static inline
struct gpio_desc *fwnode_get_named_gpiod(struct fwnode_handle *fwnode,
					 const char *propname, int index,
					 enum gpiod_flags dflags,
					 const char *label)
{
	return ERR_PTR(-ENOSYS);
}

So rather than just deleting all this code, breaking other platforms
that need this gpio, lets try a real fix. Please try this. If it
works, i will formally submit it.

If CONFIG_GPIOLIB is disabled, fwnode_get_named_gpiod() becomes a stub
function, which return -ENOSYS. Handle this in the same way as
-ENOENT, i.e. assume there is no GPIO used to reset the PHYs.

Hi,

I just found out that something goes wrong within the ARP table (well thats
what i think). I hope someone has a clue..

When i bootup the AmigaOne X5000 with the Ethernet cable connected, it just
never senses the presence of the UTP cable.
I must run the following command as root: mii-tool -R eth0 ... it Resets
the transceiver and the ethernet connection is ready to go.
But then... it randomly dies....

After some digging i found that in a working situation the ARP table is
filled with the correct info. Router address, and corresponding MAC, C mask
and Interface.

(Working)
skateman@X5000LNX:~$ arp -n
Address                  HWtype  HWaddress           Flags Mask
Iface
192.168.22.66            ether   08:5b:0e:fd:db:6a   C
eth0

No more traffic..it just suddenly dies...
skateman@X5000LNX:~$ ping www.google.com
ping: unknown host www.google.com

Rechecked the ARP... and found out it has lost the necessary info.
skateman@X5000LNX:~$ arp -n
Address                  HWtype  HWaddress           Flags Mask
Iface
192.168.22.66                    (incomplete)
eth0

Anyone??? :-)

You will also see pings die... mostly after the 12th packet and giving

the no buffer space error..

Hopefully someone might have a clue about what is happening.

Hi,

I just found out that something goes wrong within the ARP table (well thats
what i think). I hope someone has a clue..

This looks like 'normal' behaviour. It has been reported that the
device runs out of buffers. That means it will fail to receive ARP
replies. So the ARP entry will time out and be removed, as it should.

Fix the buffer problem, and ARP will likely work properly.

Hi Andrew,

How can we fix the buffer problem?

Thanks,
Christian
