Earlier quoted context omitted.

Maybe that's where they run the HDCP/DRM stuff? That's the most obvious application of a secure enclave on a GPU that I can think of, and would also explain why they won't (or can't) open it up.

Isn't HDCP/DRM implemented in ASIC hardware? There is nothing programmable there.

It's probably implemented mainly on the Platform Security Processor.

So for reference, this geohot is George Hotz who has a company Tiny Corp [0] in the space. Among a long list of things, he had a moment in the spotlight recently for a long rant [1] where he "gave up on AMD" because their drivers sucked more than he expected.

AMD GPUs are fantastic values for money when it comes to running mainstream PC games. Once you step outside that narrow box they become infuriating. My 7900XTX is probably the last AMD GPU I ever buy. It's just horrible at all the other things I want to use it for, especially and gallingly, game console emulation. For the first few months I had it I actually kept my old GTX1070 plugged into my motherboard because the eight year old $400 GPU was so much better at half my use cases than the $900 AMD card.

Anyone working on getting us out of the Nvidia monopoly on commerical AI should be praised. We need lots of competition in this space. I'm hoping Google spins off its TPU division and sells chips to everyone that wants them. I'm hoping AMD gets their act together and that they open up their drivers and stack. I'm hoping a lot of other hardware companies and compute stacks start making inroads on this. Nvidia is not j…

You'll note that AMD (and Nvidia, but that's expected) is unfortunately missing from the members list for UXL, which seems to be based on Intel's oneAPI which in turn is based in part on Khrono's SYCL:

If AMD got their act together they would go all in on open standards together with other actors in the segment, but maybe they really want to see if their rocm can repeat Cuda's success and lock in? I just want accelerators to become commodities and interchangeable like CPUs, let me write my code once and deploy on whatever hardware the user have, preferably without having to compile multiple versions.

> hoping Google spins off its TPU division

There’s a lot of stuff Google could have spun off but they seem content to ignore things until they turn out the lights.

Disclosure: I'm working on exactly that, so thank you so much for this!

I'm doing it on the high end of the spectrum, with MI300x, and a lot less drama.

Their entire stack on Linux is open-source. That part isn't a problem.

In a race against NVIDIA where every comment on here is about just how much better CUDA is than any alternative, why doesn't literally what you just said "also" have the attention of Lisa Su?

Making GPUs work properly requires years of effort so she needs a time machine to go back and start earlier.
