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

[P.A. Semi] Does the ethernet interface work on your Electra, Chitra, Nemo, and Athena board?

2015-12-07 Thread Christian Zigotzky 

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

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

Unfortunately there is no source code in that commit, it's just a

your bisect run found that the very first commit in that merge was OK:

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

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

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.

[P.A. Semi] Does the ethernet interface work on your Electra, Chitra, Nemo, and Athena board?

2015-12-01 Thread Christian Zigotzky 

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

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