FYI:

Darren Stevens wrote:Hello Christoph

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:

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

Hi All,

I released the RC6 of kernel 5.0 today.

New:

Please test all kernels.

and added it to the powerpc-dma.6 tree, please retry with that one.

Many thanks! Your Git kernel works in a virtual e5500 machine now!

I think we have reached the end of testing! All things are working with your DMA updates.

I am looking forward to testing your DMA changes in the next merge window again.

Hi All,

I released the RC8 of kernel 5.0 for testing today.

New:


Download: linux-image-5.0-rc8-X1000_X5000.tar.gz

Generations together :-) Screenshot of Fienix PowerPC with the RC8 of kernel 5.0 and with Ubuntu 10.04.4 LTS PowerPC (virtual Power Mac G4 QEMU/KVM-PR machine):

Please test it.

Thanks,
Christian
