A new powerpc-dma.6-debug branch:

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


Code: Select all
git checkout 257002094bc5935dd63207a380d9698ab81f0775

the FSL SOCs that your board uses. Let me investigate this a bit more.

As a hack to check that theory I've pushed a new commit to the
powerpc-dma.6-debug branch to use old powerpc GFP_DMA selection
with the new dma direct code:

http://git.infradead.org/users/hch/misc ... d85f403f06

And another one that drops the addressability checks that powerpc
never had:

Can you first test with both patches, and then just with the first
in case that worked?


Hi All,

I tested Christoph's latest DMA patches today. I successfully compiled kernels for the X5000 and X1000 from his Git 'powerpc-dma.6-debug' (both patches).

X5000: The kernel detects the SATA hard disk drive and boots without any problems.

X1000: The kernel boots and the P.A. Semi Ethernet works!

I will test just the first patch tomorrow.

Link to the test thread: use generic DMA mapping code in powerpc V4

Cheers,
Christian

Next step just with the first patch: 5c532d07c2f3c3972104de505d06b8d85f403f06 (use powerpc zone selection)

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


Code: Select all
git checkout 5c532d07c2f3c3972104de505d06b8d85f403f06


Link to the Git: powerpc-dma.6-debug

Results:

X5000: The kernel detects the SATA hard disk drive and boots without any problems.

X1000: The kernel boots and the P.A. Semi Ethernet works!

FYI:

Christoph Hellwig wrote:Thanks for testing! I'll prepare a new series that adds the other
patches on top of this one.


Christoph Hellwig wrote:And that was easier than I thought - we just had a few patches left
in powerpc-dma.6, so I've rebased that branch on top of
powerpc-dma.6-debug.2:

git://git.infradead.org/users/hch/misc.git powerpc-dma.6

Gitweb:

http://git.infradead.org/users/hch/misc ... erpc-dma.6

I hope the other patches are simple enough, so just testing the full
branch checkout should be fine for now.
