all: port to Windows/arm64

[vielmetti]

Opening this issue to track interest and progress in a port to windows/arm64.

This is completely separate from the open issue #26148 (windows/arm32) but might be informed by it.

The specific codebase I'm motivated by for this request is for WireguardVPN, and the specific discussion to reference is https://lists.zx2c4.com/pipermail/wireguard/2020-January/004832.html & surrounding.

What is the best option for hardware to run Windows on arm64? Does it run on a RK3399 SoC board like the Pine64 Pro?

[vielmetti]

@carlosedp All of the Windows 10 on Arm laptops that I am aware of to date are Qualcomm Snapdragon based. My daily driver laptop is a Lenovo Yoga C630, and there's a relatively new Microsoft Surface Pro X with a faster chip.

It looks like some work to get the boot sequence for rk3399 boards compatible with Windows lives at https://github.com/andreiw/rk3399-edk2 by @andreiw - with liberal warnings of things that still don't work.

It can also run on KVM, I actually do my ARM64 dev on a KVM VM on RK3399.

I would love to see an ARM64 version of go for Windows 10 so I can run it natively on the Surface Pro X:

Is what I'm currently seeing so it won't even run in emulation on this device or so it would seem.

#25084 same deal.

platform.go and a few hax... latter.

ahh poohh but did not get an arm64 windows-arm build of gox... how nice.
winstrap-master_windows_arm.zip

might help...

Did you use the 32- or 64- bit download? The 32-bit x86 version should run in emulation.

my windows wants is any golang honeypots and RPI3/4 makes for good decoys/bait...
/topSec SBC's are less expensive to utilize emulation meh..

@clarkezone fwiw, the 32-bit x86 version of Go's installer seems to work, at least from my limited testing (I'm not a Go user, I just wanted to build a Go app)

Reposting @anaisbetts's comment from elsewhere:

So, one thing to know about ARM64 on Windows is, it actually fully emulates x86 (not amd64, 32-bit apps oddly enough) for user-space apps - they Just Work (most of the time! kinda!)

So, with a bit of sleight-of-hand packaging, you can make an "ARM64" release that still mostly has x86 binaries

(I'm not sure what the performance cost of that is, though.)
