Xen hypervisor on Rock64
#5
Hi sstabellini, thanks for the suggestions.  
I tried to setup direct UEFI boot without success.  (Basically I started with the QEMU instructions and created  /boot/efi/EFI/xen/ with xen.efi , xen.cfg and so forth. )

It appears that EFI booting is skipped altogether, and for example:

Code:
rock64@rock64:~$ efibootmgr -w -L Xen -l "\EFI\Xen\xen.efi" -c
EFI variables are not supported on this system.

Looking at the Rockchip boot options diagram, it appears that either u-boot.bin or UEFI.FD is run as "Loader 2" , only for "Boot Flow 1".  Looking at the serial console output below, it seems to me the Rock64 is following "Boot Flow 2", which uses u-boot, since we see "BL31" running.

The serial console output at reboot, if I read it correctly, shows the system directly booting into u-boot.  
How can I ensure the Rock64 chooses UEFI boot?

Quote:sstabelliniHi Tumbleweed,I haven\'t tried Xen on Rock64, but I did run Xen on Pine64 successfully in the past.The mkimage step below is only required if you boot Xen from U-Boot. If you boot Xen from extlinux or another bootloader, it will actually cause troubles. Instead, to simplify the boot sequence, I would boot Xen directly from EFI, skipping extlinux completely. To do that, you need to copy xen.efi to the FAT partition, and write a xen.cfg config file. You also need to copy the Dom0 kernel, initrd and device tree to the fat partition. For instance, see this guide for booting Xen on ARM on QEMU: https://wiki.xenproject.org/wiki/Xen_ARM...em-aarch64 There are a few QEMU specific steps in there, but it also contains the steps to boot Xen directly from UEFI including an example xen.cfg.It might also be possible to boot Xen from extlinux but I don't have experience with that. I recommend booting from UEFI first. Cheers,Stefano
