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 ?
