AMD "Trusted Memory Zone" Encrypted vRAM Support Coming To Their Linux GPU Driver

[starshipeleven]

Seems AMD becomes more and more serious about fucking up those who buys their hardware for the real. They even managed to be creative enough to try that semi-opensource ways, whoa. Whole new level of treachery: "...but you have a choice: you can patch out our nasty shit away"? Oh, that's really new formula of evil

This is software support of a hardware feature. You can always patch away software support of stuff that you don't want.

You didn't purchase a copy. You purchased the license to listen to it from the copy (or specific hardware storage medium aka cd/dvd/whatever).

Once again, I repeat, I did not mean "it is mine". I only purchased it, so "a copy of it is mine".

Exactly. And to add to that, that copy is for your personal listening only. Take that CD and use it on your little business with a public space (barber shop, dry cleaning, etc) and you will hear from (insert your country's music association) what they think about your definition of "mine".

I'm all for more encryption and don't see anything wrong with this, but it leaves me scratching my head. What use could this have? What are they trying to protect?

it's used by applications that want to keep their vRAM secret or untouchable from other applications.

DRM is one potential application. GPU sharing between VMs is another big one. You don't want VMs to be able to snoop in another VM's stuff even if you are sharing the GPU (with the GPU virtualization hardware that exists in server cards)

AndyChow - It's for DRM (Digital Restrictions Management). Your own data won't be protected, don't worry.

That's probably one application. Other applications would be protecting an apps memory in the context of "cloud computing".

Is not yours, you merely licensed it.

And I refuse to pay anything for such licenses, aside from maybe the $0.01 per view it's worth (for music, thankfully DRM-free CDs and public radio exist).

I'll pay significant cash for a true owned (in the sense a paper book is owned) movie or audio CD. I have a nice collection of audio CDs bought straight from retail because of this, but movies I only pay a small amount of pocket change for third hand copies of the DRM restricted media (and don't pay for streaming anything, period -- either that comes completely from the data analytics and ads that are collected anyway or I don't watch/listen.).

And yeah, this AMD "feature" is just another restriction in a long line of them. It's why I compute with POWER9, not Epyc, and why and am looking to replace my AMD GPUs with something less restricted as soon as I can.

I wish DRM would die. I want to listen to my purchased music, not be filled with this crap.

Speaking of GEM, how is that project for a unified memory something that started because nvidia EGL Stream?

I guess they stopped working on it because GNOME and KDE have EGLStreams support now.
