That’s why we call them mitigations rather than fixes; the first pass makes Spectre more difficult to pull off and/or reduces the performance impact of avoiding it. The next pass, which I agree will be a huge amount of work, will actually address the root cause.
Anyway, I think you’re probably right, but would like confirmation. I can live with Spectre. Meltdown not so much.
The effort is appreciated nonetheless. I am also interested in the answer though, but I can’t imagine Zen+ going without ECC considering Zen’s origins and usage in Epyc as well.
What are the IOMMU groupings like on the x470 boards?
What is the Linux support like?
Does StoreMI work with Linux?
Those are the things i’m wanting to know.
ready to pull the trigger on a 2700x in the next couple of weeks with a view to replacing my E3-1231v3 haswell box. I definitely want to run looking-glass.
If it’s like previous AMD CPUs then ECC compatibility will be there on the CPUs, it’s up to the motherboard manufacturers to implement the feature however.
IIRC it’s like that on Ryzen, Bulldozer, Phenom II, and I think before were like that. Unregistered/Unbuffered only either way.
