- wtallis 8y agoI'm not sure if there are even any true hardware mitigations actually shipping yet. I think the closest we have are products that ship with stock microcode implementing the same changes that aftermarket microcode updates applied to existing products.

- saagarjha 8y agoThat's because they effectively ossified the software fix in hardware, right? At some point we might be able to come up with a real way to fix the issue.
- bonzini 8y agoFor most of them (not Spectre v1) hardware fixes are easy, just adding some extra bits to cache or BTB tags. Problem is it's whack-a-mole.
