Isn't the whole point of attention, some context comprehension in the stochastic parrot machine.

You can get the user's head position using WorldTrackingProvider, that's enough for xeyes to follow you across the room.

There's even a sample app close enough

> copper can barely support 10G and is terribly power hungry when it does that.

AFAIK, thunderbolt cables are also copper - so what trickery do they use for supporting USB4-80? i believe both connectors use differential pair wires for signalling.

Half life alyx and their push for openVR has made a big impact in that part of the gaming world.

But yeah, their games are just as filled with lootbox, crates, skin garbage as other low effort money grabs; saving grace being its all cosmetics only (and they’re private about their financials).

ordering lock acquisition is a tested strategy to avoid deadlocks; so locking the cache lines sorted by PA would cover that?

> My personal dream is that vms would support pci pass through and so you can just spin up a Linux vm and let it drive the gpus.

SR-IOV is just that? and is well supported by both Windows and Linux.

They’re used by the internal register renamer/allocator so if it sees you’re storing the results to memory then reusing the named register for a new result - it will allocate a new physical register so your instruction doesn’t stall for the previous write to go through.

the TB5 link (RDMA) is much slower than direct access to system memory

Nvidia has been investing in confidential compute for inference workloads in cloud - that covers physical ownership/attacks in their thread model.

Yes, but parent comment definitely implied they weren't talking about people running on the latest and best out there. Even the middle-grade smartphones today are leaps and bounds better than the atom from 2010.

> And yet, if I go to Youtube or just about any other modern site, it takes literally a minute to load and render, none of the UI elements are responsive, and the site is unusable for playing videos. Why? I'm not asking for anything the hardware isn't capable of doing.

but the website and web renderer are definitely not optimized for a netbook from 2010 - even modern smartphones are better at rendering pages and video than your atom (or even 8350u) computers.

What do you mean by that? Most syscalls are still interrupt based.

Is this firmware bit flip known? couldn't find anything off google.
