Hi Zide,
Thank you very much, you were right. I've had RELOC already enabled, but apparently one also need to have CONFIG_HV_RAM_START 2MB aligned. I've set it to 0x1400 0000 and now my hypervisor manages to execute entire init_paging() function.
... but now it crashes in cpu.c, init_percpu_lapic_id(). A block of code from init_pcpu_pre():
printf("aaaaaaa7\n");
if (!init_percpu_lapic_id()) {
panic("failed to init_percpu_lapic_id!");
}
printf("aaaaaaa8\n");
"7" gets printed out, neither "8" nor panic does.
I guess something is wrong with the interrupts? If it means anything, I've made no particular modifications related to interrupts, and our board generally works well with Linux.
Best regards,
Dubravko

Hi Dubravko,
Host MMU page size is 2MB in ACRN hypervisor. It seems to me that the direct cause for crash could be CONFIG_HV_RAM_START(0x13151000) is not 2MB aligned.
Did you disable relocation (RELOC in Kconfig)? By default RELOC is enabled and it allocates memory from EFI and overwrites the user defined CONFIG_HV_RAM_START, which is supposed to be able to avoid the 2MB alignment issue.
In case of you prefer to disable hypervisor relocation, you may need to make sure that CONFIG_HV_RAM_START is configured to the memory that is of EfiConventionalMemory(7) type. You may find out the available memory by calling dump_e820() in misc/efi-stub/boot.c, before emalloc_reserved_aligned().
Best Regards,
Zide

Hi Zide,
You were right again, I don't know how it happened but my MAX_PCPU_NUM was set to 3, while there are 4 CPUs.
MADT and DMAR tables seem to be correct.
I'm using acrn.efi, RELOC is enabled.
Now the hypervisor seems to be almost working... The initialization seems to complete fine, then I'm getting a huge number of printouts like these:
[836682306us][cpu=0][vm0:vcpu0][sev=6][seq=31854]:Exit Reason: 0x0000000000000001
[836722306us][cpu=0][vm0:vcpu0][sev=6][seq=31855]:Exit Reason: 0x0000000000000001
[836762306us][cpu=0][vm0:vcpu0][sev=6][seq=31856]:Exit Reason: 0x0000000000000001
[836802306us][cpu=0][vm0:vcpu0][sev=6][seq=31857]:Exit Reason: 0x0000000000000001
They continue indefinitely. As far as I can tell, there are no errors (unless these indicate some errors), but also nothing else happens, just these printouts.
RELEASE=1 build doesn't display the above printouts, but also nothing seems to happen.
I think I might not have configured loading of the next stage (Linux loader) correctly, so it's possible that ACRN just doesn't have anything to do. The tutorials aren't quite clear regarding doing that, for new custom boards. Though if that's the problem, I would expect at least some warning message to be displayed. I'll check that first anyway.
Thank you and best regards,
Dubravko

Hi Dubravko,
Did you boot ACRN from acrn.efi (UEFI) or acrn.bin (SBL), or acrn.32.out (Grub)? RELOC is enabled for acrn.efi, but not
others.
For the init_percpu_lapic_init() issue, it's highly possibly that the user defined MAX_PCPU_NUM is less than the physical
CPU number from ACPI table.
Other than that, probably you need to debug the parse_madt() and see if it can't find MADT table or corrupted MADT so that
it finds 0 pcpus.
BTW, you can pull this PR to your code which may help your bring-up since it enables early panic() and other pr_err()
messages.

Hi Zide,
Your instructions were clear, unfortunately I'm still having issues.
I have followed the instructions from https://projectacrn.github.io/latest/tutorials/kbl-nuc-sdc.html, and first upgraded Clear Linux to the same version as used there, just in case. Also I've rebuilt ACRN with CONFIG_CONSOLE_LOGLEVEL_DEFAULT now set to 5 (previously was 6).
I've verified that I have all the required files on the EFI partition. I've added a new boot entry with:
sudo efibootmgr -c -l "\EFI\acrn\acrn.efi" -d /dev/mmcblk0 -p 1 -L "ACRN hypervisor" -u
"bootloader=\EFI\org.clearlinux\bootloaderx64.efi uart=bdf@0:18.0"
Then I've set clr-boot-manager options according to instructions. This all went smoothly.
After the reboot, ACRN loads. While it's waiting in the boot menu it continuously prints out a lot of these:
[21481383us][cpu=0][vm0:vcpu0][sev=4][seq=827]:Spurious vector: 0x50.
[21498377us][cpu=0][vm0:vcpu0][sev=4][seq=828]:Spurious vector: 0x50.
[21515373us][cpu=0][vm0:vcpu0][sev=4][seq=829]:Spurious vector: 0x50.
[21532360us][cpu=0][vm0:vcpu0][sev=4][seq=830]:Spurious vector: 0x50.
[21549353us][cpu=0][vm0:vcpu0][sev=4][seq=831]:Spurious vector: 0x50.
When I choose the first option that I believe should start the Service OS, it then continuously prints out these:
[34072934us][cpu=3][vm0:vcpu3][sev=5][seq=1645]:VM 0 Starting CPU 3
[34079998us][cpu=0][vm0:vcpu0][sev=3][seq=1646]:vlapic: Start Secondary VCPU3 for VM[0]...
[34089037us][cpu=3][vm0:vcpu3][sev=5][seq=1647]:VM 0 Starting VCPU 3
[34096100us][cpu=0][vm0:vcpu0][sev=3][seq=1648]:vlapic: Start Secondary VCPU3 for VM[0]...
[34105131us][cpu=3][vm0:vcpu3][sev=5][seq=1649]:VM 0 Starting VCPU 3
[34112188us][cpu=0][vm0:vcpu0][sev=3][seq=1650]:vlapic: Start Secondary VCPU3 for VM[0]...
... and it never gets to SOS or ACRN console.
As far as I know, there is nothing wrong with any of the CPU cores; all are enabled in BIOS; "top" in regular Clear Linux shows that all 4 cores are alive and occasionally doing something.

Hi Dubravko,
If you see endless vmexit messages, it's possibly that you have successfully loaded the guest kernel.
You may remove the vmexit logs by configuring CONFIG_CONSOLE_LOGLEVEL_DEFAULT to any number < 6.
Build it with "RELEASE=1" disables the hypervisor serial console so you won't be able to see anything. So it's discouraged
to do that during bring-up.
I'm expecting you can see the console prompt: "ACRN:\>", and you can try some basic commands like "help", "vm_list",
"vcpu_list", etc. If you find any guest VM is running from "vm_list" command, you can switch to the guest console by
"vm_console 0", and switch back to HV console by pressing "Ctrl + Space".
https://projectacrn.github.io/latest/tutorials/debug.html?highlight=console
If you don't see any VM running, you may following this tutorial (of cause you can try other scenario):
https://projectacrn.github.io/latest/tutorials/kbl-nuc-sdc.html
The key point is at the end you need to install a clear Linux bzImage and acrn.efi (sample:
misc/efi-stub/clearlinux/acrn.conf) in the EFI partition, and the "Linux" line in acrn.efi points to the bzImage you
installed.

Zide

Hi Dubravko,
If you see endless vmexit messages, it's possibly that you have successfully loaded the guest kernel.
You may remove the vmexit logs by configuring CONFIG_CONSOLE_LOGLEVEL_DEFAULT to any number < 6.
Build it with "RELEASE=1" disables the hypervisor serial console so you won't be able to see anything. So it's discouraged
to do that during bring-up.
I'm expecting you can see the console prompt: "ACRN:\>", and you can try some basic commands like "help", "vm_list",
"vcpu_list", etc. If you find any guest VM is running from "vm_list" command, you can switch to the guest console by
"vm_console 0", and switch back to HV console by pressing "Ctrl + Space".
https://projectacrn.github.io/latest/tutorials/debug.html?highlight=console
If you don't see any VM running, you may following this tutorial (of cause you can try other scenario):
https://projectacrn.github.io/latest/tutorials/kbl-nuc-sdc.html
The key point is at the end you need to install a clear Linux bzImage and acrn.efi (sample:
misc/efi-stub/clearlinux/acrn.conf) in the EFI partition, and the "Linux" line in acrn.efi points to the bzImage you
installed.

Hi Zide,
You were right again, I don't know how it happened but my MAX_PCPU_NUM was set to 3, while there are 4 CPUs.
MADT and DMAR tables seem to be correct.
I'm using acrn.efi, RELOC is enabled.
Now the hypervisor seems to be almost working... The initialization seems to complete fine, then I'm getting a huge number
of printouts like these:
     [836682306us][cpu=0][vm0:vcpu0][sev=6][seq=31854]:Exit Reason: 0x0000000000000001
     [836722306us][cpu=0][vm0:vcpu0][sev=6][seq=31855]:Exit Reason: 0x0000000000000001
     [836762306us][cpu=0][vm0:vcpu0][sev=6][seq=31856]:Exit Reason: 0x0000000000000001
     [836802306us][cpu=0][vm0:vcpu0][sev=6][seq=31857]:Exit Reason: 0x0000000000000001
They continue indefinitely. As far as I can tell, there are no errors (unless these indicate some errors), but also
nothing else happens, just these printouts.
RELEASE=1 build doesn't display the above printouts, but also nothing seems to happen.
I think I might not have configured loading of the next stage (Linux loader) correctly, so it's possible that ACRN just
doesn't have anything to do. The tutorials aren't quite clear regarding doing that, for new custom boards. Though if
that's the problem, I would expect at least some warning message to be displayed. I'll check that first anyway.
Thank you and best regards,

Hi Dubravko,
Did you boot ACRN from acrn.efi (UEFI) or acrn.bin (SBL), or acrn.32.out (Grub)? RELOC is enabled for acrn.efi, but not
others.
For the init_percpu_lapic_init() issue, it's highly possibly that the user defined MAX_PCPU_NUM is less than the physical
CPU number from ACPI table.
Other than that, probably you need to debug the parse_madt() and see if it can't find MADT table or corrupted MADT so that
it finds 0 pcpus.
BTW, you can pull this PR to your code which may help your bring-up since it enables early panic() and other pr_err()
messages.

Hello,
Please find attached the log file and my acrn.conf.
My old BIOS didn't have any settings related to Mwait, so I've installed newer BIOS which has "Monitor Mwait Enable" and I've ensured it's set to "Disabled". Changing the BIOS seems to have also changed some data in logs, but the overall behavior is the same.
New acrn.efi seems to work reasonably well. Our custom board is obviously specific, but in general it is similar to reference Leaf Hill CRB.
After the last printout from the log, everything stops working (there is nothing on the screen attached to the board and the keyboard doesn't do anything; also typing in the serial terminal doesn't do anything).

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 according to instructions from https://software.intel.com/en-us/firmware/sites/default/files/intelatome3900-0.71-buildinstructions.txt, plus we added support for our board (the link apparently no longer works). In general it works very well.

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 possible to enable X2APIC from BIOS?
Without X2APIC, ACRN doesn't work. Though I'm expecting ACRN should go beyond what it is now.
BTW, can you remove "quiet" from the Linux bootargs? This may not really help, but I'm puzzled why it doesn't print any Linux logs.
From the logs, one big difference with my images (acrn.efi + bzImage) is that now it doesn't repeat the SIPI sequence (INIT -> Start up -> INIT -> Start up) endless, instead, after launching 3 VCPUs, the guest sends broadcasting SIPI INIT and Start Up only. This is a good news, but not sure that's because of the new acrn.efi, or the bzImage?

Zide

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 setting has some thing like "do not use x2apic", which prevents Linux from enabling X2APIC. Or you may check why the guest doesn't switch to X2APIC from native Linux dmesg?
2) Need Linux logs to help debugging.
Attached is the ACRN built with the following hack, which directs guest serial prints directly to HV console.
Seems Linux goes to the path of numachip_wakeup_secondary() to send SIPIs to secondary CPUs, which we didn't see before.
It's good to see Linux early pintk t help address the issue.

In the meantime, if you want, you can hack ACRN with the following and it won't launch any VMs and the HV console is supposed to be working. It's just a way to check that ACRN is "generally" working on the HW and you may play with some HV console commands.
