Radxa Cubie A7A - Allwinner a733

[Nick A]

For those with a Radxa Cubie A7A, I made a custom Armbian Build using the BSP kernel. 

https://github.com/NickAlilovic/build/releases/tag/Radxa-a7a-v0.2

https://github.com/NickAlilovic/build/tree/Radxa-A7A

 

Now supports automatic first boot configuration by default. No need for a usb serial device to boot into a desktop image. First boot takes awhile to load. If you are using a server image you need a usb serial device/ssh to interact with the console. There is no Framebuffer console support in the BSP kernel.

 

If you want to edit the automatic first boot configuration read the documentation.

Thanks, is KVM supported?

[Nick A]

@eli It's compiled in the kernel

Fixed the automatic first boot configuration on Bookwarm. Now you can boot the desktop image without a usb serial device.

Hey @Nick A, first of all, thanks for providing us with the build, I flashed and tried the image, But I could not see kvm enabled in the system. Is this expected?

 

some example outputs:
 

~$ ls -l /dev/kvm
ls: cannot access '/dev/kvm': No such file or directory

~$ sudo dmesg | grep -i kvm
[    0.184039] kvm [1]: HYP mode not available

 

also no output on 

 

lscpu | grep Virtualization

To check if KVM is compiled into the kernel, use the following command: 

grep CONFIG_KVM /boot/config-$(uname -r)

 

CONFIG_KVM=y
CONFIG_KVM_MMIO=y
CONFIG_KVM_VFIO=y
CONFIG_KVM_GENERIC_DIRTYLOG_READ_PROTECT=y
CONFIG_KVM_XFER_TO_GUEST_WORK=y

You also need to ensure your CPU supports virtualization. Check with:  

egrep -c '(vmx|svm)' /proc/cpuinfo

 

0

 

A return value greater than 0 indicates virtualization support is present.

 

CPU doesn't support virtualization.

 

Check the official Radxa image. Using these commands. I doubt it works. I'm using the same kernel config and Board support package.
