Hi All,

Christoph's new patch fixes the problems with the P.A. Semi Ethernet! :-)

Now can you test with this patch and the whole series?

I've updated the powerpc-dma.6 branch to include this fix.

Finally got to compile a working version from this, not sure what was wrong with my previous builds...

I've tested on my X5000, all working good so far, in fact my Soundblaster live sound card seem to like the changes and works without patching the kernel. (Nice)

Not sure when I'll get chance to test on X1000 though.

Update: I found the following in my dmesg, think it points to an of-by-one error in the pfn selection:

Re: Kernel 5.0

Post by xeno74 »

Hi All,

The kernel developers want to use the generic DMA mapping code for PowerPC machines. They modified the source code for testing. Maybe they want to add it to the kernel 5.1. They have released a kernel with the DMA modifications. We are testing kernels from this Git currently.

Link to the Git: powerpc-dma.6

I have created a kernel from this Git for testing.

Download: vmlinux-5.0-rc5-2-AmigaOne_X1000_X5000.tar.gz

Please test it carefully.

Thanks,
Christian

Not sure that anything I do is "careful testing" but I booted with 5.0-rc5-2-... yesterday and rc6 now. No new problems in either fienix or MATE..
