in-band ECC is also a thing. In that scenario, you give up some capacity for the ECC bits but stay with the same DRAM config as before. (in-band ECC is present on Elkhart Lake Atoms and on Tegra Xavier for example)

Apple had one too at the time, launched together with the iPhone. (iPhone Bluetooth Headset) Technological limitations caused that to be shelved until much later.

It’s not based on LLVM, that’s way too heavy for the use case. The same backend is used for AoT and JIT compilation. It uses a custom lightweight IR that’s really close to x86 itself, with a big focus towards reducing translation times. Ros

For Rosetta (1), QuickTransit was bought up by IBM. Rosetta disappeared not very long after that.

> Pointer authentication isn’t in 3rd party processes though Still isn’t, because the arm64e ABI isn’t stable. As such, any binaries not bundled with the OS, including Apple applications, use the arm64 ABI without pointer authentication.

The DP altmode didn’t provide enough bandwidth, which is why the best experience is over the Thunderbolt alternate mode. edit: you can in fact get HBR3 working, what's not working at full rate with DP instead of thunderbolt is the USB3

Qubes uses a VM (without GPU acceleration in most scenarios) as the isolation boundary. That has performance and usability downsides… The sandbox keeps being tightened each release.

Being a TPM is one of the Intel ME and PSP’s functionalities. Making a TPM that’d be secure against custom firmware is possible, but isn’t very implemented across the industry. It’d need measuring the hash of the loaded firmware itself to h

The code involved isn’t even that long… but mistakes can result in very annoying behavior. Debugging issues with that code is a pain.

Yeah, the PSP with its opaque firmware even handles DRAM initialisation on Zen processors, so that you cannot run without it at all.

Signed firmware, probably why they are so reluctant to share those for newer cards for Nouveau… because it’d break their market segmentation.
