vm-basic-pci demo is not working for arm64
Hi, I was trying to run the L4 demo *vm-basic-pci* for *arm64* using the command $ make qemu E=vm-basic-pci but It didn't work because of the missing 2 files : * virt-arm_virt-64_pci.dtb : which is requested by the *modules.list* file in the line :
module[arch=arm64,fname=virt-pci.dtb] dtb/virt-arm_virt-64_pci.dtb
* virt-pci.dtbo : which is requested by the *vm-basic-pci.cfg* by the configuration
if (L4.Info.arch() == "arm64") then dt = "-drom/.fdt" overlay = "*-drom/virt-pci.dtbo*" else dt = "-drom/virt-pci.dtb" overlay = "" end
I searched for both files in the whole *l4re-snapshot-23.10.1* directory but I couldn't find them Where can I find those necessary files to run *vm-basic-pc*i demo?

This is actually a typo. Please change this line to overlay = "-drom/virt-pci.dtb" Best, Matthias.
else dt = "-drom/virt-pci.dtb" overlay = "" end

Hi Mohamed, can you please check your arm64 build tree and look into the folder 'assets/dtb/'? There should be links to all the .dtb files of uvmm. The link of the file in question on my machine is: [...]/.build-arm64/pkg/uvmm/configs/dts/OBJ-arm64_armv8a-std-l4f/virt-arm_virt-64_pci.dtb If the file is missing in the linked folder, please check the corresponding source directory: <src>/pkg/uvmm/configs/dts/ If virt-arm_virt-64_pci.dts isn't in there, you can download it from our development version of L4Re on github and recompile the uvmm package. https://github.com/kernkonzept/uvmm/blob/master/configs/dts/virt-arm_virt-64... If the file is there, please check that '<arm64-build>/assets' directory is in your MODULE_SEARCH_PATH. Let me know, if this solves the missing file problem.

I upgraded L4 version to 24.08 instead of 23.10 because 24.08 contains the missing virt-arm_virt-64_pci.dts file. I'm building for arm64 and when I run the demo VM-basic-pci, I got the following error ! I didn't change anything in the dts/dtb or ned scripts excepting the typo of
overlay = "-drom/virt-pci.dtbo"
What is the problem here ? [image: image.png] On Mon, Oct 21, 2024 at 11:35 AM Philipp Eppelt < philipp.eppelt@kernkonzept.com> wrote:

Hi Mohamed, I'm happy to see you resolved the issue. If possible, please prefer a text log from the serial console over a picture, because the text log is longer and thus provides more information about the booted system. uvmm show this error, when memory regions overlap. In this case RAM and the intc device overlap. The intc device is specified in the device tree you passed to uvmm. Here, the device tree does not contain explicit RAM regions, so uvmm sets up the default RAM region, which spans the area starting at zero up to the size of the RAM you configured in the ned script. In this case, RAM covers the area [ 0: fff'ffff] (256MB). The itc device wants to allocate the area [0x0800'0000 : 0x0800'ffff] which is contained within the already existing RAM allocation. Thus the error message. You have two options, either specify the areas where the RAM should be placed in the memory node of the device tree or move the intc device such that it doesn't overlap. For this setup this means above 0x1000'0000. Cheers Philipp Am 22.10.24 um 09:36 schrieb Mohamed Dawod:

Hi, Thanks Philipp for your patience and valuable support. I changed the areas where the RAM should be placed in the memory node of the device tree and it worked. Now, I want to test the pci bus by connecting a virtio-blk-pci device via qemu to be mounted on /dev/vda to do that, I run qemu using the following options : *$ qemu-system-aarch64 -kernel
/home/dawod/workspace/l4re-snapshot-24.08.0/build_aarch64/l4/images/l4re_VM-basic-pci.elf -serial stdio -M virt,virtualization=true,iommu=smmuv3 -cpu cortex-a57 -m 4096 --display none -drive if=none,file=/home/dawod/storage/disk.rootfs.ext4,format=raw,id=disk0 -device virtio-blk-pci,drive=disk0*
but the VM hangs in the booting stage while trying to create the /dev/vda block device which will be responsible for handling the added disk. *please* *find attached a text log from the serial console * : vm-blk-pci.log <https://mail.google.com/mail/u/0?ui=2&ik=b05e32a9ef&attid=0.1&permmsgid=msg-a:r-4942377897740831663&view=att&disp=safe&realattid=f_m2lp0t191> [image: image.png] Many Thanks, Regards On Tue, Oct 22, 2024 at 6:54 PM Philipp Eppelt < philipp.eppelt@kernkonzept.com> wrote:

uvmm show this error, when memory regions overlap. In this case RAM and the intc device overlap. The intc device is specified in the device tree you passed to uvmm. Here, the device tree does not contain explicit RAM regions, so uvmm sets up the default RAM region, which spans the area starting at zero up to the size of the RAM you configured in the ned script. In this case, RAM covers the area [ 0: fff'ffff] (256MB). The itc device wants to allocate the area [0x0800'0000 : 0x0800'ffff] which is contained within the already existing RAM allocation. Thus the error message.
You have two options, either specify the areas where the RAM should be placed in the memory node of the device tree or move the intc device such that it doesn't overlap. For this setup this means above 0x1000'0000.
Cheers Philipp

I upgraded L4 version to 24.08 instead of 23.10 because 24.08 contains the missing virt-arm_virt-64_pci.dts file. I'm building for arm64 and when I run the demo VM-basic-pci, I got the following error ! I didn't change anything in the dts/dtb or ned scripts excepting the typo of
overlay = "-drom/virt-pci.dtbo"
What is the problem here ?

Hi Mohamed,
can you please check your arm64 build tree and look into the folder 'assets/dtb/'? There should be links to all the .dtb files of uvmm. The link of the file in question on my machine is:
[...]/.build-arm64/pkg/uvmm/configs/dts/OBJ-arm64_armv8a-std-l4f/virt-arm_virt-64_pci.dtb
If the file is missing in the linked folder, please check the
corresponding
source directory:
<src>/pkg/uvmm/configs/dts/
If virt-arm_virt-64_pci.dts isn't in there, you can download it from
our
development version of L4Re on github and recompile the uvmm package.
https://github.com/kernkonzept/uvmm/blob/master/configs/dts/virt-arm_virt-64... < https://github.com/kernkonzept/uvmm/blob/master/configs/dts/virt-arm_virt-64...
If the file is there, please check that '<arm64-build>/assets'
directory is in
your MODULE_SEARCH_PATH.
Let me know, if this solves the missing file problem.
Cheers, Philipp

Hi Mohamed, I'm not quite certain where this issue comes from. My hunch is, it's an interrupt issue. Please try to cherry-pick this commit [1] to uvmm and see if this helps. The commit is new and probably not part of the snapshot. Another thing is that you configured qemu to use legacy virtio devices. Please add `disable-legacy=on,disable-modern=off` to -device virtio-blk-pci,... Also note, that hardware pass-through of PCIe devices on arm64 is not yet supporting MSI-X. Meaning, the device tree node of the PCIe host bridge device for uvmm should not mention the msi-map property. Legacy IRQ should work, though.

Hi Philipp, The mentioned commit didn't help. Also the added qemu configuration didn't change anything. I added `earlyprinkt=serial,ttyS0` in order to show more logs from the VM kernel but nothing new. I also think that it's an interrupt issue! I'm not an expert in device tree nodes, How can I use Legacy IRQ instead of MSI-X ? Thanks, Regards On Wed, Oct 23, 2024 at 5:34 PM Philipp Eppelt < philipp.eppelt@kernkonzept.com> wrote:

I'm happy to see you resolved the issue. If possible, please prefer a text log from the serial console over a picture, because the text log is longer and thus provides more information about the booted system.
uvmm show this error, when memory regions overlap. In this case RAM and the intc device overlap. The intc device is specified in the device tree you passed to uvmm. Here, the device tree does not contain explicit RAM regions, so uvmm sets up the default RAM region, which spans the area starting at zero up to the size of the RAM you configured in the ned script. In this case, RAM covers the area [ 0: fff'ffff] (256MB). The itc device wants to allocate the area [0x0800'0000 : 0x0800'ffff] which is contained within the already existing RAM allocation. Thus the error message.
You have two options, either specify the areas where the RAM should be placed in the memory node of the device tree or move the intc device such that it doesn't overlap. For this setup this means above 0x1000'0000.
Cheers Philipp

Hi Mohamed, just a quick reply. Long one comes later. Am 24.10.24 um 12:47 schrieb Mohamed Dawod:
Hi Philipp,
The mentioned commit didn't help. Also the added qemu configuration didn't change anything. I added `earlyprinkt=serial,ttyS0` in order to show more logs from the VM kernel Sorry, I mistyped: the linux cmdline argument is `earlyprintk=serial,ttyS0`. (not earlyprinkt).
Cheers, Philipp
but nothing new.
I also think that it's an interrupt issue! I'm not an expert in device tree nodes, How can I use Legacy IRQ instead of MSI-X ?
Thanks, Regards

Hi Mohamed,
I'm not quite certain where this issue comes from. My hunch is, it's an interrupt issue. Please try to cherry-pick this commit [1] to uvmm and see if this helps. The commit is new and probably not part of the snapshot.
Another thing is that you configured qemu to use legacy virtio devices. Please add `disable-legacy=on,disable-modern=off` to -device virtio-blk-pci,...
Also note, that hardware pass-through of PCIe devices on arm64 is not yet supporting MSI-X. Meaning, the device tree node of the PCIe host bridge device for uvmm should not mention the msi-map property. Legacy IRQ should work, though.
Hint: add `earlyprinkt=serial,ttyS0` to the guest linux' command line to see more information from the guest linux boot.
Let's see what these things change.
Cheers, Philipp

Hi Philipp, I wrote it correctly, "earlyprintk" instead of "earlyprinkt". but nothing changed. On Thu, Oct 24, 2024 at 3:20 PM Philipp Eppelt < philipp.eppelt@kernkonzept.com> wrote:
Hi Mohamed,
just a quick reply. Long one comes later.

Hi Philipp,
The mentioned commit didn't help. Also the added qemu configuration didn't change anything. I added `earlyprinkt=serial,ttyS0` in order to show more logs from the VM kernel Sorry, I mistyped: the linux cmdline argument is `earlyprintk=serial,ttyS0`. (not earlyprinkt).
Cheers, Philipp
but nothing new.
I also think that it's an interrupt issue! I'm not an expert in device tree nodes, How can I use Legacy IRQ instead of MSI-X ?
Thanks, Regards

Hi Mohamed,
I'm not quite certain where this issue comes from. My hunch is, it's an interrupt issue. Please try to cherry-pick this commit [1] to uvmm and see if this helps. The commit is new and probably not part of the snapshot.
Another thing is that you configured qemu to use legacy virtio devices. Please add `disable-legacy=on,disable-modern=off` to -device virtio-blk-pci,...
Also note, that hardware pass-through of PCIe devices on arm64 is not yet supporting MSI-X. Meaning, the device tree node of the PCIe host bridge device for uvmm should not mention the msi-map property. Legacy IRQ should work, though.
Hint: add `earlyprinkt=serial,ttyS0` to the guest linux' command line to see more information from the guest linux boot.
Let's see what these things change.
Cheers, Philipp

Hi Philipp, Regarding the PCI bus issue (hardware pass-through of PCIe devices on arm64 is not yet supporting MSI-X) Is there a method to make the device tree node of the PCIe host bridge device for uvmm uses the Legacy IRQ instead of MSI-X ? I tried to just remove the msi-map property from the device tree node of the PCIe host bridge device but nothing changed! Is there more configuration/changes should be added ? Thanks in advance, Regards On Sun, Oct 27, 2024 at 11:34 AM Mohamed Dawod <mohamed.dawod@avelabs.com> wrote:
Hi Philipp, I wrote it correctly, "earlyprintk" instead of "earlyprinkt". but nothing changed.

Hi Mohamed,
just a quick reply. Long one comes later.

Hi Philipp,
The mentioned commit didn't help. Also the added qemu configuration didn't change anything. I added `earlyprinkt=serial,ttyS0` in order to show more logs from the VM kernel Sorry, I mistyped: the linux cmdline argument is `earlyprintk=serial,ttyS0`. (not earlyprinkt).
Cheers, Philipp
but nothing new.
I also think that it's an interrupt issue! I'm not an expert in device tree nodes, How can I use Legacy IRQ instead of MSI-X ?
Thanks, Regards

Hi Mohamed,
I'm not quite certain where this issue comes from. My hunch is, it's an interrupt issue. Please try to cherry-pick this commit [1] to uvmm and see if this helps. The commit is new and probably not part of the snapshot.
Another thing is that you configured qemu to use legacy virtio devices. Please add `disable-legacy=on,disable-modern=off` to -device virtio-blk-pci,...
Also note, that hardware pass-through of PCIe devices on arm64 is not yet supporting MSI-X. Meaning, the device tree node of the PCIe host bridge device for uvmm should not mention the msi-map property. Legacy IRQ should work, though.
Hint: add `earlyprinkt=serial,ttyS0` to the guest linux' command line to see more information from the guest linux boot.
Let's see what these things change.
Cheers, Philipp
