It would be very funny if a spec lawyering session on SVE2 accidentally uncovered a hypervisor bug in the worlds largest hypervisor vendor.

What else?

I do wonder if #MTE will be exposed this time around.

Other questions? Do we *also* get real (read: full) #SVE and #SVE2
if so, how wide per core?

There's also the possibility of #sme2 but that's probably a step too far

Resource:
For those starting/looking at #SVE and #SVE2, @dougall made a superb instruction visualizer with presets for various Arm SVE enabled processors!

Worth looking at to understanding what instructions are actually* doing under the hood: https://dougallj.github.io/asil/

Google pixel is getting #ARMV9 LETS GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Full #SVE 1 and #SVE2!

ARM (aarch_64):
#SVE2 Using a phone as a dev board, you're good to go. Latest flagship Samsung, OnePlus phones feature SVE2.
#SME Not accessible yet. Maybe we'll see dev boards, but for now it's [redacted] only.

RISC-V:
#RISCVV: Prelaunch spec Dev boards exist, but not much exists with the 1.0 (or higher) spec implemented in hardware.
#RISCVM: FPGA prototyping only, spec is WIP

Use an FPGA ¯\_(ツ)_/¯

#SVE2 has now landed in #QEMU master and will be in 6.1. Check it out for enhanced #SVE goodness: https://gitlab.com/qemu-project/qemu/-/commit/92f8c6fef13b31ba222c4d20ad8afd2b79c4c28e
