Re: Getting ACRN to work

Chen, Zide
 

Hi Dubravko,

 

Yes, Service OS kernel can be acrn-kernel only because it has some ACRN specific modules. But UOS kernel doesn’t have such limitation, though normally we build UOS kernel from the same source with different config (kernel_config_uos).

 

You can run Ubuntu rootfs + acrn-kernel for SOS:

And “real” Ubuntu as UOS:

Best Regards,

Zide

Hi Zide,

 

I've noticed that for Service OS kernel, you've provided a link to a dedicated repository. I've had a meeting today and was asked to ask the experts on the mailing list to please clarify:

  • Is the dedicated SOS kernel the only one that will work with ACRN?
  • Does UOS also use a special kernel?
  • Related to the previous questions: we would like to use Ubuntu for both SOS and UOS, because many of our customers are familiar with it. Is that possible? If it's not possible to simply use such a distribution right away, is there a well-defined API or some other kind of interface in ACRN-specific kernels, that we could port to other kernels?

Best regards,

Dubravko

Hi Zide,

 

I've managed to download the kernel as instructed, enable the required Ethernet driver, and compile the kernel.

 

Today when I wanted to test it, my board has died, for no particular reason. Hardware team thinks it's not repairable. I'll have to wait a couple of days at least until I get another one.

 

Best regards,

Dubravko

Hi Dubravko,

I assume x2apic is working for you now since you can mount rootfs. Then you may treat the Ethernet driver issue just like
it on the native Linux, for example, /lib/modules/ matches kernel version 'uname -r'? driver module exists? etc.

You may compile your own kernel like this:

$ git clone https://github.com/projectacrn/acrn-kernel.git
$ cd acrn-kernel
$ cp kernel_config_uefi_sos .config
$ make menuconfig
$ make

Best Regards,
Zide
