Phoronix: IBM Turns To More Optimizations For Linux On POWER10

With it appearing all the essentials are in place for IBM POWER10 Linux support, in recent days we have seen an uptick in patches from IBM engineers working on POWER10 performance optimizations...

Just remember that you are IBM hardware 100% of the time....

"the benchmark numbers on POWER10 were lesser than expected"

I swear to God all the kernel devs need to take a basic English refresher course.

Too bad we're probably not going to see P10 systems from Raptor Computing Systems:

Never tell never. If IBM does P10 with generic DDR4/5 then Raptor may go ahead with their P10....

But that's one of the ways to solve the issue. The other is a third-party open OMI controller or convincing micron to open theirs.

Though OMI is way overkill for most desktop/workstation needs.

But even a process refresh 10nm on P9 and upgrade to ddr5 could be a viable product.


And since the ISA is open, there's still the possibility a more destkop oriented design pops up. Libre-SOC is one in the works, But there are potentially others...

But the tool-chain often explicitly target to P9/P10, etc, instead of specific sub-features of the ISA bring an additional wrinkle to the process.

Even has memory encryption like EPYC! Not sure if it has register encryption too, though. But EPYC is a moot point when basically no one running them in a server has the security features on! Crazy... Find me anyone running AMD in a production server with the new security features enabled, I dare you (except, supposedly Google Compute)!

Looking forward to the benchmarks!
