when windows dev boot from acpi https://github.com/shawnguo2/linux/commits/wdk2023-acpi-6.2 display is working over efifb build in ethernet is working build in wifi use ath11k and armbian firmware is missing all of this https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/log/ath11k/WCN6855/hw2.0/ all usb ports working cpufreq don't

But still 1.display port switched off after booting 2.build in ethernet isn't working and usb2 ports isn't working

When I add more stuff to device tree it started to run on full speed It is 2.5x faster then rock 5

I was able to boot with this branch https://github.com/jhovold/linux/tree/wip/sc8280xp-v6.2-rc8 and with microsoft dev kit patches on top of that https://github.com/shawnguo2/linux/commits/devkit-dt-6.2-rc5 and this kernel command line clk_ignore_unused efi=novamap earlycon=efifb console=efifb build in ethernet don't work as not all usb-c ports are active so you will need to connect usb-c ethernet to usb-c ports on the side for speed Cpufreq-info show 3GHz but device is running as on lowest freq(800MHz) as that is my experience with running benchmarks

Some UEFI is able to start only signed GRUB/KERNEL Are there any support this this? I found that for that purpose suse has some signed shim

Surface pro X is same hw as windows dev box 2023 https://github.com/linux-surface/surface-pro-x

@balbes150 Can you explain how UEFI is working on arm? Is it passing some dts or how the linux kernel know what drivers should it start ?

https://www.microsoft.com/en-us/d/windows-dev-kit-2023/94k0p67w7581 UEFI can be way how to boot it maybe

As ubuntu 22.04 has realy up to date compiler. Is it possible to force armbian to use local copiler? linaro gcc compiler is 8.x but gcc in ubuntu 22.04 is 11.x. Is it possible to force armbian to use local compilers? Or can armbian update gcc to 11. x ??
