Read through the comments thread on this gist: https://gist.github.com/ErikAugust/724d4a969fb2c6ae1bbd7b2a9e3d4bb6 It's specifically testing Spectre, which has wider affects across CPUs and will be harder to fix. In the thread, there's someone who has it going on PowerPC. There are a number of older CPUs being tested in that thread, I think when I went through it yesterday someone had already tested a P2 or P3 and found it to be vulnerable. If I have time this week, I'll bring up a SPARC64 and an Alpha and see if I can get the PoC code running.

These flaws can be *potentially* exploited on any processor that features speculative execution. No idea as to why there is no comprehensive list of affected CPUs as of yet.

It’s been said that the Meltdown/Spectre flaws affect CPU’s as far back as 1995. Which in some opinions possibly could put some of the affected processors into the ‘vintage’ range. But I’ve yet to see a comprehensive list of all processors affected. Intel released a list, but that only goes back to around 2011 or so with the branding change to “Core” and others released in the time since.
I’m curious about exactly what CPU devices, regardless of manufacturer, other than those listed, that are also affected. So including ARM processors, AMD, PowerPC?, G3/4/5? that may vulnerable to those flaws. And where they got the 1995 date from, because there’s a fair number of disused processors in that timeframe as well.
Anyone have any insights on this? -- Normal Person: Hey, it seems that you know a lot. Geek: To be honest, it's due to all the surfing I do. Normal Person: So you go surfing? Normal Person: But I don't think that has anything to do with knowing a lot... Geek: I think that's wrong on a fundamental level. Normal Person: Huh? Huh? What?
