IBM still put 40x cores inside POWER chips no ?
Oh yeah that's true. I guess most folks don't know that, or that they run RHEL on them.
Is there a reason for not having those dts files in mainline then? If nothing else, it would document what machines are still being used with future kernels.
Sorry that part was a joke :D Those chips don't run Linux.
Nice to know :)
What's the plan then, do we still want to keep 40x in the kernel ?
I guess we keep it for now.
Perhaps we mark it BROKEN for a few releases and see if anyone complains?
If yes, is it ok to drop the oldies anyway as done in my series https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=172630 ?
Yeah let's do it. I would love to get rid of that horrible PPC405_ERR77() sprinkled all through our atomics.
(Note that this series will conflict with my series on hugepages on 8xx due to the PTE_ATOMIC_UPDATES stuff. I can rebase the 40x modernisation series on top of the 8xx hugepages series if it is worth it)
Yeah if you can rebase that would be great.
cheers
