Works well here :!:

I'm still on PowerPC Remix 2017 0.8 .
I can try out the new Mesa 18.2.2 unless it depends on 0.9 in some way.

Thanks,
tom


Hi Tom,

Many thanks for testing the RC8! :-) I haven’t tested Mesa 18.2.2 on the MATE PowerPC Remix 0.8 yet. In my point of view it should work on it.

Cheers,
Christian

Hi All,

Greg Kroah-Hartman released the final version of kernel 4.19 today. In the development time, Darren created a new Nemo patch and the kernel developers added Darren's Nemo/PASEMI updates to the official kernel. Many thanks to Darren for the Nemo patch and for the Nemo/PASEMI updates. There were some USB issues with the kernel 4.19 on the X5000. Darren figured out where the problem is. He did a bisect and found the bad commit. He also found a bad kernel config option. Disabling 'HAVE_ARCH_PREL32_RELOCATIONS' in arch/powerpc/Kconfig fixed the problems. He reported the bad commit to the Linuxppc-dev mailing list and after that the kernel developers removed 'HAVE_ARCH_PREL32_RELOCATIONS' in arch/powerpc/Kconfig. He also solved the mem issue with the SoundBlaster Live! It works without the mem=3500M boot argument now.
Thanks a lot to Tom for testing the kernels on his X1000 and many thanks to Skateman, kilaueabart, and acefnq for testing the kernels on the X5000.

Hi All,

I compiled the stable kernel 4.19.1 on my AmigaOne X1000 yesterday. Additonally I added initial ramdisks for the X5000 and X1000 to the stable kernel 4.19.1. I only use ramdisks for booting with a LABEL or UUID. You can boot the kernels with the ramdisks with the following commands:

X1000:

Code: Select all
ramdisk -z -addr=0x2400000 -fatfs cf0:initrd.img-4.19.1


Booting with a LABEL (For example Julian's ubuntu MATE 16.04 from a USB flash drive):

Code: Select all
setenv bootargs "root=LABEL=Ubuntu_16.04"


Code: Select all
boot -elf- noints -fatfs cf0:vmlinux-4.19


X5000:

Booting with a LABEL (For example the MATE PowerPC Remix 0.9):

Code: Select all
setenv bootargs root=LABEL=AMIGAONE


For example loading the kernel, dtb file, and ramdisk from the first FAT partition on a hard disk:

Code: Select all
load sata 0:1 1000000 uImage-4.19


Code: Select all
load sata 0:1 1c00000 cyrus.dtb


Code: Select all
load sata 0:1 2000000 uInitrd


Code: Select all
bootm 1000000 2000000 1c00000

Please test the stable kernel 4.19.1 and the ramdisks.

Thanks,
Christian

You can rename the LABEL of a partition with the following command:

For example rename the partition /dev/sdb7 to AMIGAONE:

Code: Select all
tune2fs -L AMIGAONE /dev/sdb7

Why is the loading routines on the X5000 so fast? That's not normal for an AmigaOne cpmputer.

Also, what's with the loading and entry point of zero? That would crash a normal computer. Trying to load at zero on my XE immediately crashes it. :o
