I am excited about the prospect of Linux on another powerful aarch64 platform like Snapdragon Elite. But, as far as I can tell from the diagram on the link shared, you will boot into EL1 and not EL2. This means that you cannot run a hardware accelerated VM on KVM (via something like qemu). This makes a Snapdragon Linux laptop not as useful. BTW Asahi Linux on Apple Silicon enters on EL2 which allows qemu+KVM. Enterin…

> "Making our firmware openly available (in Linux-firmware)" is a big one. How are firmware updates currently distributed ? The "linux-firmware" repo is the standard place to put it, my reading is that Qualcomm are doing this in the right way.

I think that for many use-cases containers already replaced VMs even for developers. And you obviously can't run accelerated x86 VMs either way. So probably won't be a big issue.

«linux-firmware» is the goto place to dump firmware that goes to all linux distributions

Earlier quoted context omitted.

There are some early benchmarks which put its performance behind iPad: - Snapdragon X Elite (2,574 / 12,562) - iPad M4 (3,630 / 13,060)

Since we’re talking about Linux support, the iPad benchmarks seem irrelevant. It’s a completely different kernel. Asahi Linux benchmarks on an M3 MacBook Air would be the closest thing here.
