Hi All,

I compiled the alpha2 of kernel 6.15 with the first PowerPC updates today.

Download and further information: github.com

Please test the kernels.

Thanks,
Christian

OK, good to know. I will not revert to ABIv1 Linux kernels for the X1000. Thanks for clarifying.

Just touching on this. I checked the included kernels on the Debian installers to find the ABI. But I cannot see where to find it. Apart from expected differences I cannot tell the difference. How do you tell the ABI of a PPC64 ELF?

Edit. I just realised it was in the flags. So never mind, it wasn't in an obvious place, like ABI. For comparison with kernel 6.12.17-powerpc64-smp:

But I cannot see where to find it.

You have found it.

Thank you. Now, I know, that Debian PPC64 has switched to the ABIv2.

Thanks. Yes I just noticed myself. Edited my post.

I'm not sure when as I've just started testing it. I haven't tested Debian directly since I finished producing the Debian Jessie installer iso for AmigaOne XE/SE/u. I did read that ABI2 was LE specific so must have been opened up to BE recently.

So I've found my libpcre.so.3 error is known about but not specific to my situation with breaking system udev on boot. Mostly it affects working systems and comes up when some terminal program failed to load it. People have tried to solve it by reinstalling libpcre3 package but it failed to work.

Hi All,

The merge window for the kernel 6.15 has been started and here is the first alpha for testing.

So I installed and tested the new alpha1. I got some interesting results compared to 6.14. So it was able to boot on Xenial, Zesty, Fienix and Debian 64.

All except Debian use a ramdisk and root label. Debian uses root device with no ramdisk. But out of the 4 Xenial still continues to get stuck. It keeps giving load module errors, network errors and takes a minute to find the root device. It was, however, able to boot without the libpcre errors this time which seems strange.

I'll test the alpha2 next and collect a log.

FYI: openSUSE Tumbleweed 20230628-3 PPC64 and Fedora 28 Server PPC64 work with our new ABIv2 kernels.
