Does anyone know if there is any processor(in phone) with SVE/SVE2? As SVE/SVE2 SHOULD be in all new ARMv9.0-A + CPU cores.

I did have a chance to test only Qualcomm Snapdragon cores ( Samsung Galaxy S23).

Snapdragon 888 probably the first one have SVE, Snapdragon 7/8 gen all have Qualcomm® Type-1 Hypervisor, so what's your test, abel to run any linux on it?
I am using default android on Samsung Galaxy S23 with userland https://play.google.com/store/apps/details?id=tech.ula So any advice how to run it?
Qualcomm disables SVE (masked at the hypervisor level) on all their silicon. If you want SVE on a phone roday, your options are Tensor G3, Exynos 2200/2400 or MediaTek phones with ARMv9 CPUs.

Or if you have hypervisor execution level code exec (including an unfused phone), you can patch up that limitation.

So I have this https://en.wikipedia.org/wiki/Windows_Dev_Kit_2023

And we can run ubuntu on that https://github.com/armbian/build

There isn't any hypervisor running on that and still no SVE So any advice ?

This runs Cortex-X1C and A78C, which are of the generation _just_ before the one that got SVE
Looking at the docs, it doesn't look like ARMv9-A strictly requires FEAT_SVE to be implemented.

What that means in practice is anyone's guess.
