  1. 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
  2. Surface pro X is same hw as windows dev box 2023 https://github.com/linux-surface/surface-pro-x
  3. @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 ?
  4. https://www.microsoft.com/en-us/d/windows-dev-kit-2023/94k0p67w7581 UEFI can be way how to boot it maybe
  5. 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 ??
  6. Why armbian put debian.list to ubuntu package list (/etc/apt/sources.list/debian.list)? I am on ubuntu so I don't understand why should I have mix of debian and ubuntu packages
  7. I mount this one on Hikey970 I can only recommend!
  8. I just try 5.7rc1 build of linux kernel for odroid c2 And armbian can't create linux kernel package It looks like some problem in https://github.com/armbian/build/blob/master/patch/misc/general-packaging-5.6.y.patch
  9. PURE ARMBIAN sudo BETA=yes EXPERT=yes ./compile.sh and choose your RK3288 board and as OS choose ubuntu 20.04 and then server and then instal gnome apt install ubuntu-desktop everything should run out of the box for the first time we should have working ubuntu gnome with gpu accleration on many boards lima and panfrost is working JUST fine
  10. My board is some HDMI dongle like device with RK3288 but is is powered from micro usb Kernel version: 5.5.11 I didn't modify kernel dts files so I didn't add 500Mhz
  11. I am testing RK3288 with ubuntu 20.04 (gnome) btw NICE And I have some problems with panfrost and I am looking for anybody with RK3288 device that can confirm or not same behavior. Problem is that when I switch GPU to 600MHz sudo bash -c 'echo "userspace" > /sys/class/drm/card1/device/devfreq/ffa30000.gpu/governor' sudo bash -c 'echo "600000000" > /sys/class/drm/card1/device/devfreq/ffa30000.gpu/userspace/set_freq' and when I run glmark2-es2 or glmark2-es2-wayland I start to see https://pastebin.com/NuYqHdxH in kernel.log So I made bugreport(https://gitlab.freedesktop.org/mesa/mesa/-/issues/2693) for panfrost and they think that problem is in low voltage on gpu as everything is fine on 400MHz So anybody can try? just build ubuntu 20.04 for your RK3288 device sudo BETA=yes EXPERT=yes ./compile.sh server build should be fine and then apt install ubuntu-desktop ubuntu 20.04 has almost latest mesa so everything work just fine
  12. mainline rules All amlogic boards are also on mainline mainline u-boot will be also fine. it should work I think so some users can try lima drivers on odroid c2 and if anybody want arm opengl es drivers on odroid n2 And as always mainline kernel has better stability. Btw what about passing coherent_pool=4M to kernel. Any plan to add it? I saw your post
