As far as I understand, 64-bit Qemu UEFI code doesn't expect to see and run 32-bit EFI executable.

Correct, as far as UEFI is concerned, a 32bit ARM binary could as well be a MIPS one ;). It's a different, unsupported platform for it.

When I try to use qemu-uefi-aarch32.bin as firmware, then I see the following:

Initialization of device cfi.pflash01 failed: failed to read the initial flash content

As far as I understand, qemu-uefi-aarch32.bin is in wrong format, but there are no other files in ovfm rpm package.

Which ovmf package are you looking at? I'm not sure we properly package OVMF for AArch32. But you can always try with the Linaro built ones :) http://snapshots.linaro.org/components/kernel/leg-virt-tianocore-edk2-upstre...

What is the proper way to run JeOS-efi.armv7? Is it supposed to work in qemu?

It should work, yes. It should also work on any platform that has distro boot enabled and runs with recent U-Boot. Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

The file on the link I provided works just fine for me:

Thanks, now it almost works. I managed to run with 2.9.1 and Linaro's DEBUG UEFI image. However, I only Grub works well. The kernel seems to be not booted. I set loglevel=8 and console=ttyS0,115200 manually in grub config, but still don't see any info from the kernel.

By the way. Does the OVMF generate FDT for the kernel? -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Try ttyAMA0 instead.

Hm, no luck.

I use latest version of aarch32 OVMF firmware from openSUSE:Factory:ARM. Well, then, I suppose, I have to see appropriate EFI driver (FdtClientDxe ? ) in the driver list.

I don't think the fact that the driver is loaded tells you anything.

I assume you can't boot the VM properly? Does grub see the DT table? lsefi in grub should show you iirc.

If it doesn't show it, but instead shows ACPI tables, can you try to pass -no-acpi to QEMU?

There is nothing FDT-related at GRUB side. This is why I started to search who is responsible for providing FDT. -no-acpi also doesn't change anything. grub> lsefi Handle 0x7f260f90 loaded image Handle 0x7f260a90 decompress Handle 0x7f25a490

Hi,

There is one more thing that is unclear to me now. As far as I understand there is no other way except FDT to provide hardware layout for armv7l kernel. Then, who is responsible for FDT loading? As far as I understand it is grub2 task to load FDT from the table at b1b621d5-f19c-41a5-.... And FDT is completely provided by UEFI firmware. In case of u-boot, dtb file is loaded from the disk by means of u-boot and placed into memory. What should happen here when OVMF is used? In theory, it has to be configured to generate FDT from QEMU config somehow, right? Or pass-through entire FDT from Qemu hypervisor?

It basically passes through the device tree that's generated by QEMU, yes. However, OVMF defaults changed a while back and it only exposes ACPI tables instead of DT in newer versions on AArch64 IIRC.

Maybe something went wrong and they changed them for armv7 as well by accident?

I use latest version of aarch32 OVMF firmware from openSUSE:Factory:ARM. Well, then, I suppose, I have to see appropriate EFI driver (FdtClientDxe ? ) in the driver list.

I don't think the fact that the driver is loaded tells you anything.

I assume you can't boot the VM properly? Does grub see the DT table? lsefi in grub should show you iirc.

If it doesn't show it, but instead shows ACPI tables, can you try to pass -no-acpi to QEMU?

There is nothing FDT-related at GRUB side. This is why I started to search who is responsible for providing FDT. -no-acpi also doesn't change anything.

Hm, that is the object list. Maybe it was lsefisystab?

Ok, here FDT is present (b1b621d5-...). How can I dump it from grub console? If I do it right, then It has correct magic header 0xd00dfeed. grub> dump 0x7ffde000 100 d0 0d fe ed 00 01 10 00 00 00 00 40 00 00 1a 70 00 00 00 30 00 00 00 11 00 00

Looks all green to me then. I guess you actually get into the kernel then with a working device tree, but just don't see output?

Sure, I've managed to dump and decomile FDT.

There is nothing FDT-related at GRUB side. This is why I started to search who is responsible for providing FDT. -no-acpi also doesn't change anything.

grub> lsefi

Hm, that is the object list. Maybe it was lsefisystab?

Ok, here FDT is present (b1b621d5-...). How can I dump it from grub console? If I do it right, then It has correct magic header 0xd00dfeed.

Looks all green to me then. I guess you actually get into the kernel then with a working device tree, but just don't see output?

Sure, I've managed to dump and decomile FDT. As far as I don't see any output, something is wrong either with serial port or interrupt controller?

Hm, with qemu debug and grub debug on, I see the following:

Jumping to Linux... Taking exception 4 [Data Abort] ...from EL1 to EL1 ...with ESR 0x25/0x96000037 ...with DFSR 0x37 DFAR 0xfffdd000

When I use -kernel and -initrd instead of -bios in qemu command line, then the kernel boots successfully.

Surprisingly it works. Thank you. However, with -m 1024 it stil doesn't work. 2018-02-17 0:41 GMT+03:00 Alexander Graf :

When I use -kernel and -initrd instead of -bios in qemu command line, then the kernel boots successfully.

I just ran across a very similar issue and it boiled down to the fact that grub puts the DT outside the linear memory map of Linux.

Can you try to boot with -m 768 to ensure we always fit? That should make it work.

Thanks,
