"CVE-20222-23960." I think that's 2022.

At Phoronix CVE stands for "content verification eliminated".

In all seriousness, Love the content. But the typos are getting redonkulous lately.

I wonder how many years it will take for Raspberry Pi Foundation talk about this. They still have not announced anything about the Pi4 and Spectre from 2017-2018.

A vulnerability from the 203rd century? That's some very speculative execution.

Are these covered by mitigations=off? Or is there another way to turn these off? I want my performance back.

I start to have mixed feelings towards OoO designs, there are a plethora of exploits out there..

Was this another case of BSD being left out in the cold?

Wow nice to hear that sandybridge/ivybridge are not affected. I guess i have to stick with those old machines for another decade or so.
