Hi All,

I compiled kernels for the X5000 and X1000 from Christoph's branch 'powerpc-dma.6' today.

Gitweb: powerpc-dma.6

Code: Select all
git clone git://git.infradead.org/users/hch/misc.git -b powerpc-dma.6 a


The X1000 and X5000 boot but unfortunately the P.A. Semi Ethernet doesn't work.

Error messages (X1000):

Christoph Hellwig wrote:It seems like the pasemi driver fails to set a DMA mask, but seems
otherwise 64-bit DMA capable. The old PPC code didn't verify the
dma mask during the map operations, but the x86-derived generic
code does.

This patch just sets the DMA mask.

Olof: does this look ok? The DMA device seems to not directly
bound by the net driver, but not really used by anything else in tree
either..

I patched the source code from the Git powerpc-dma.6 with the pasemi_mac patch today. Unfortunately the P.A. Semi Ethernet doesn't work with the patched Git kernel.

After that I tried it with the patch applied over the working setup again.

Code: Select all
git checkout b50f42f0fe12965ead395c76bcb6a14f00cdf65b
(powerpc/dma: use the dma_direct mapping routines)

I patched 'powerpc/dma: use the dma_direct mapping routines' with the pasemi_mac patch but unfortunately after compiling and booting, the P.A. Semi Ethernet doesn't work either.
