No. Same situation is with Lenovo X13s featuring the same SoC. You can boot Linaro hacked Debian with kernel 6.1.y / 6.2.y leaning on device tree. 0 Quote Link to comment Share on other sites More sharing options...
0 m][sko Posted January 20 Author Share Posted January 20 @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 ? 0 Quote Link to comment Share on other sites More sharing options...

There is an EDK2-EFI variant, it uses two variants - DTB or ACPI. 0 Quote Link to comment Share on other sites More sharing options...

0 hexdump Posted January 22 Share Posted January 22 i think the arm version of the surface pro 9 is close to the devkit - surface pro x is an older design using a snapdragon 8cx gen2 (i think) and not the gen3 the devkit is using and which is a very different soc 0 Quote Link to comment Share on other sites More sharing options...

0 m][sko Posted March 4 Author Share Posted March 4 (edited) 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 Edited March 4 by m][sko 0 Quote Link to comment Share on other sites More sharing options...
