Hi All,
Linus Torvalds has released the
RC2 of kernel
7.2 for testing.
I have compiled it for X1000 and e5500 machines (X5000/20, X5000/40, Mirari, and QEMU VMs).
Download and further information:
github.com
Monitoring the cross-compilation of the RC2 with PROXMOX:
Please test the kernels.
Thanks,
Christian

I've also found the L2 caches missing as well. Including the System Profiler. Which lists the 2 caches as being 0kB. And 0 BogoMips. Definitely bogus.
But the worse it looks for me, is my L1 caches. Mine is only 64KB while everyone else has 128KB L1 caches. I never knew this until now. Why does my X1000 have an inferior CPU?

Do you have a screenshot or a shell output with a working L2 cache from the older kernels?

But under linux is reported only L1 cache, and L2 cache is allways 0. getconf output is L1=L2=0
See also
lstopo - shows two single-core sockets and no L2 cache, and not one dual-core.
Do anybody know origin of these number ( hwtree or something) ?
Do have this impact on speed with linux, or is it only "cosmetics" info?
Is the same problem on other platforms? I have to look on Pegasos and powermac.
This problem already existed in 2020.
I have found an old lstopo screenshot from 2017 but there aren't any L2 caches.

No, not that I know of. Not in the screenshots I found in my older installs. I still have a few older kernels installed so could test those which are still functional.
