Hi All,

Does the ethernet interface on your Electra, Chitra, Nemo, and Athena board work with the release candidates of the kernel 4.4? Unfortunately the P.A. Semi ethernet doesn't work on our Nemo boards with the release candidates of the kernel 4.4. We have set the following entries in the kernel config:

CONFIG_NET_VENDOR_PASEMI=y
CONFIG_PASEMI_MAC=y

Could you please test the P.A. Semi ethernet on your P.A. Semi boards?

Thanks in advance,

Christian

It's not clear from your descriptions what is not working. Does the driver probe function find a device? Does the interface show up in the kernel? Can it send/receive packets?

Also please CC netdev.

Thanks.

Hi Denis,

Thank you for your answer. Sorry because of my description.

Yes, the driver probe function finds the device.

With kernel 4.4-rc3:

dmesg | grep -i eth0

[ 2.297473] eth0: PA Semi GMAC: intf 5, hw addr 02:00:e0:0a:30:00

dhclient eth0

RTNETLINK answers: Cannot allocate memory

With kernel 4.1.13:

dmesg | grep -i eth0

[ 2.328115] eth0: PA Semi GMAC: intf 5, hw addr 02:00:e0:0a:30:00
[ 37.130466] eth0: Link is up at 100 Mbps, full duplex.

Cheers,

Christian

Hi All,

I have tested the PA Semi Ethernet with the kernels 4.2.3 and 4.3.0 today. With the kernel 4.2.3 it works but with the kernel 4.3.0 final it doesn't work.

After that I tested some git kernels and release candidates of 4.3.

Hi all,

We tested some 4.3 kernels on a P.A. Semi reference board. Ultimately, ethernet does not work, though on the reference board, the interface is detected, gets link, but will not pass any packets/traffic.

Somewhere in the source code of the commit "'powerpc-4.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux (2015-09-03 23:41:38 (GMT)" is the problem.

Could you please help us to solve the problem?

Thanks in advance,

Christian Zigotzky

Hi All,

I have tested the PA Semi Ethernet with the kernels 4.2.3 and 4.3.0 today. With the kernel 4.2.3 it works but with the kernel 4.3.0 final it doesn't work.

After that I tested some git kernels and release candidates of 4.3.

Kernel 4.3 git from Tue Sep 01, 2015 -> PA Semi Ethernet works
Kernel 4.3 git from Wed Sep 02, 2015 -> PA Semi Ethernet works
Kernel 4.3 git from Thu Sep 03, 2015 -> PA Semi Ethernet works
Kernel 4.3 git from Fri Sep 04, 2015 -> PA Semi Ethernet doesn't
work (Merge tag 'powerpc-4.3-1': https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ff474e8ca8547d09cb82ebab56d4c96f9eea01ce)
Kernel 4.3 git from Sat Sep 05, 2015 -> PA Semi Ethernet doesn't work
Kernel 4.3 git from Mon Sep 07, 2015 -> PA Semi Ethernet doesn't work
Kernel 4.3 git from Wed Sep 09, 2015 -> PA Semi Ethernet doesn't work
Kernel 4.3 git from Fri Sep 11, 2015 -> PA Semi Ethernet doesn't work
Kernel 4.3 RC1 from Sun Sep 13, 2015 -> PA Semi Ethernet doesn't work
Kernel 4.3 RC2 from Mon Sep 21, 2015 -> PA Semi Ethernet doesn't work

The problematic commit must be between Thu Sep 03, 2015 at 09:37 AM (UTC +2) and Fri Sep 04, 2015 at 7:38 PM (UTC +2) in the linux git.

Linux git: Between https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/?ofs=15500
and https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/?ofs=15200.

Maybe https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ff474e8ca8547d09cb82ebab56d4c96f9eea01ce.

Unless I miss something, that's the kind of regression that "git bisect" is designed to find.

Hi all,

We tested some 4.3 kernels on a P.A. Semi reference board. Ultimately, ethernet does not work, though on the reference board, the interface is detected, gets link, but will not pass any packets/traffic.

Somewhere in the source code of the commit "'powerpc-4.3-1' of
git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux (2015-09-03 23:41:38 (GMT)" is the problem.

Could you please help us to solve the problem?

Hi Christian,

Unfortunately there is no source code in that commit, it's just a merge. And your bisect run found that the very first commit in that merge was OK:

[390fd5929f52bdfb9dfcc03820041ba556780f4a] cxl: Set up and enable PSL git bisect good

So I'm not convinced your bisect run was correct, sorry.

My pasemi is booting OK, but I haven't had time to test the network. If you remind me next week I will make sure network is working on my board.

Are you testing your board with your additional patch as well? Or just vanilla mainline?

Hi Michael,

Thanks a lot for your answer. We tested some vanilla mainline 4.3 kernels on an Electra reference board. Additionally we tested some patched 4.3 kernels on our Nemo boards.

It would be really fantastic, if you could fix the problem.

Cheers,

Christian

Hi Michael,

I checked out the Linux git till the commit 'powerpc-4.3-1'

git checkout ff474e8ca8547d09cb82ebab56d4c96f9eea01ce

Output:

Checking out files: 100% (13843/13843), done.
Note: checking out 'ff474e8ca8547d09cb82ebab56d4c96f9eea01ce'.

You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example:

git checkout -b new_branch_name

HEAD ist jetzt bei ff474e8... Merge tag 'powerpc-4.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

The P.A. Semi Ethernet doesn't work with the powerpc-4.3-1 merge. I reverted this merge with:

git revert ff474e8ca8547d09cb82ebab56d4c96f9eea01ce -m 1

Hi all,

I have some good news for you. I was able to fix the issue with the P.A. Semi Ethernet. It was a problem with the new DMA handling. The patch ' [RFC/PATCH,v2] powerpc/iommu: Support "hybrid" iommu/direct DMA ops for coherent_mask < dma_mask (https://patchwork.ozlabs.org/patch/472535/)' is the problem.

I had patched the following files before I compiled a kernel.

arch/powerpc/Kconfig
arch/powerpc/include/asm/device.h
arch/powerpc/include/asm/dma-mapping.h
arch/powerpc/include/asm/iommu.h
arch/powerpc/kernel/dma-iommu.c
arch/powerpc/kernel/dma-swiotlb.c
arch/powerpc/kernel/dma.c
arch/powerpc/platforms/powernv/pci-ioda.c
arch/powerpc/platforms/pseries/iommu.c
arch/powerpc/sysdev/dart_iommu.c
include/asm-generic/dma-mapping-common.h

The P.A. Semi Ethernet works again with the patched kernel.

I am happy. :-)

Please fix the issue in the kernel source code.

Thanks in advance,

Christian

Send me your .config and the full dmesg output. I can't seem to reproduce here.

Hi All,

I have tested the PA Semi Ethernet with the kernels 4.2.3 and 4.3.0 today. With the kernel 4.2.3 it works but with the kernel 4.3.0 final it doesn't work.

Looking at the changes in pasemi I don't see any significant changes to the driver so the best thing you can try is to bisect the bad commit.

Quoted 92 lines

After that I tested some git kernels and release candidates of 4.3.

Kernel 4.3 git from Tue Sep 01, 2015 -> PA Semi Ethernet works Kernel 4.3 git from Wed Sep 02, 2015 -> PA Semi Ethernet works Kernel 4.3 git from Thu Sep 03, 2015 -> PA Semi Ethernet works Kernel 4.3 git from Fri Sep 04, 2015 -> PA Semi Ethernet doesn't work (Merge tag 'powerpc-4.3-1':

The problematic commit must be between Thu Sep 03, 2015 at 09:37 AM (UTC +2) and Fri Sep 04, 2015 at 7:38 PM (UTC +2) in the linux git.

Hi Denis,

Thank you for your answer. Sorry because of my description.

Yes, the driver probe function finds the device.

With kernel 4.4-rc3:

dmesg | grep -i eth0

[ 2.297473] eth0: PA Semi GMAC: intf 5, hw addr 02:00:e0:0a:30:00

dhclient eth0

RTNETLINK answers: Cannot allocate memory

With kernel 4.1.13:

dmesg | grep -i eth0

[ 2.328115] eth0: PA Semi GMAC: intf 5, hw addr 02:00:e0:0a:30:00
[ 37.130466] eth0: Link is up at 100 Mbps, full duplex.

Cheers,

Christian

Hi All,

Does the ethernet interface on your Electra, Chitra, Nemo, and Athena board work with the release candidates of the kernel 4.4? Unfortunately the P.A. Semi ethernet doesn't work on our Nemo boards with the release candidates of the kernel 4.4. We have set the following entries in the kernel config:

Quoted 4 lines

CONFIG_NET_VENDOR_PASEMI=y
CONFIG_PASEMI_MAC=y

Could you please test the P.A. Semi ethernet on your P.A. Semi boards?

It's not clear from your descriptions what is not working. Does the driver probe function find a device? Does the interface show up in the kernel? Can it send/receive packets?

Also please CC netdev.

Thanks.
