Hi All,

Could you please test Christoph's kernel on your PASEMI and NXP boards? Download:

'git clone git://git.infradead.org/users/hch/misc.git -b powerpc-dma.5 a'

Thanks,
Christian

I successfully tested this kernel on a virtual e5500 QEMU machine today.

Command: ./qemu-system-ppc64 -M ppce500 -cpu e5500 -m 2048 -kernel uImage-dma -drive format=raw,file=MATE_PowerPC_Remix_2017_0.9.img,index=0,if=virtio -nic user,model=e1000 -append "rw root=/dev/vda" -device virtio-vga -device virtio-mouse-pci -device virtio-keyboard-pci -usb -soundhw es1370 -smp 4

QEMU version 3.1.0.

I don't know why this kernel doesn't recognize the hard disks connected to my physical P5020 board and why the onboard ethernet on my PASEMI board doesn't work. (dma_direct_map_page: overflow)
