@staticsafe AMD: 😏

@staticsafe they forgot how to do that because of their market share over the last decade or so, they're figuring out how to smile right now

smug smiling is a few years off for AMD

@moz @staticsafe I don't think AMD is at risk for complacency until the end of 2020 if they stay on the path they are on. This is a huge opportunity for management to try to keep their engineers hungry and humble.

#amd #stayhungrystayhumble #manifesto #processor

@nicseltzer @staticsafe they're not complacent, they've forgotten how to do that too

LB:

"AMD processors are not subject to the types of attacks that the kernel
page table isolation feature protects against. The AMD microarchitecture
does not allow memory references, including speculative references, that
access higher privileged data when running in a lesser privileged mode
when that access would result in a page fault."

jesus Tom have some mercy

love to drag a competitor on fucking LKML

Intel PR yesterday:

"looks like the Management Engine thing is slowly dying down, finally time to chill"

Intel PR today:
"oh for fucks sake"

@staticsafe the speculative references bit is terrifying

@er1n @staticsafe it's nothing too unusual, how else would you keep all those pipelines constantly filled and flowing?

@hirojin @staticsafe no, /that's/ understandable, the implication that speculative references can access higher privileged data from a lower privileged mode

@er1n @staticsafe i have just one thing to say about that

oops

@staticsafe
I've been an AMD since a long ago and I was always mocked for being a guy that support that shitty processors but the truth behind I did that was quite simple. Before AMD, Intel always understimated their clients, like they were junkes addicted about their underpriced product. Like most drug dealers do with their old clients and that changed when AMD came to the game. Since the almost defeated state of AMD with i7 processors, Intel began with that same way...

@staticsafe
... And now when Rizen processors came out, Intel came out with the i9 processor... Where that processor was before? They have a better product but they gave us for years their undeveloped processors of i7 series like it's was the best? So that made me trust less and less in Intel and now with that big security leak was confirmed that my suspiction was founded. Intel trink we are a bunch of idiots that buy whatever have a Intel logo because it's good...

@staticsafe these things are soooooo fucking complicated, and there are SO MANY ways they could go wrong

@er1n @staticsafe my suspicion is that we're running of lower-hanging fruit so people are starting to get creative with looking for this stuff

cf all the side-channel attacks been popping up over the past few years

@er1n @staticsafe the houses we've built are literally the wandering castle

and they're just as magical

and stable
