Hi Dubravko, I learned from Fei that one of his patch(merged, for security) might impact PCIe devices in SOS, could you please help check if your HV include it? commit

Hi Zide, Thank you for explaining all the kernel and Ubuntu options. It looks like all the use cases we are interested in are covered. I've got a replacement board and I'm continuing with ACRN. I've

Topic (2/26): How to build a Yocto based SOS on ACRN Presenter: LIU, Fuzhong Short description: The Yocto Project (YP) is an open source collaboration project that helps developers create custom

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

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

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.

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

That’s great. For the Ethernet issue, ‘lspci -k’ to check if the device exists in SOS and how about the driver status? If you are using a customized kernel, make sure the related ethernet

Hi Shuo, Thank you, you were right, with your fix ACRN loads the Service OS on my board too. Now I have the issue that Ethernet doesn't work (while it does in regular Clear Linux), so I can't download

Hi Dubravko, You are very welcome! Additional to Shuo's suggestion, here are some advices: 1) X2APIC. I added this log but didn't see it from your log. That's why I claimed that the guest didn't

Hi Dubravko, I glanced through the discussion and found it might be a similar issue that I hit today with UP2 board. My problem is that with ACRN enabled the linux kernel cannot bootup APs,

Hi Zide, 1) X2APIC I see that it's not mentioned anywhere in ACRN log (and I suppose it should be), but it seems to be enabled somehow in non-hypervised Linux: Our BIOS does not have a GUI setting to

One more thing you may try: add maxcpus=1 to acrn.conf options, so we can skip the SIPI issue and see how it goes.

Hi Dubravko, 1) Enable X2APIC from guest Linux Actually ACRN checks X2APIC capability and it goes panic w/o it. So the host CPUID must have X2APIC support. We met one case where the BIOS DMAR

Hi Dubravko, With my acrn.efi, it switches to guest console by default. Does it switch back to ACRN console by pressing "Ctrl + Space"? The logs show that X2APIC is not enabled by Linux. Is it

Hi Zide, I've checked all the menus and settings in our BIOS, unfortunately I couldn't find anything that looks like the mentioned setting or similar or related to it. We are using coreboot, built

Hi Dubravko, In the meantime, is there something like "AP Thread Idle Manner" in your BIOS? And changing its setting makes any difference? Best Regards, Zide
