Metis PCIe

​ I have a 4 AIPU Axelera card, and it is plugged into the Dell PowerEdge R760 server.Currently the card fails to enumerate all the Metis devices, and I see PCIE AER errors in the logs relatd to the Metis devices.Below is the the output of the axdevice command. Attached problem report as well.Have you seen this issue before ? Command line logs:(axelera-env) user@r760-sales-demo:~$ sudo lspci -d 1f9d: -vt-[0000:0c]---01.0-[0d-12]----00.0--+-02.0-[11]----00.0 Axelera AI Metis AIPU (rev 02) \-03.0-[12]----00.0 Axelera AI Metis AIPU (rev 02)(axelera-env) user@r760-sales-demo:~$ cat /proc/cmdlineBOOT_IMAGE=/boot/vmlinuz-6.8.0-111-generic root=UUID=5c7f0039-5e33-4e4b-85e3-9d0215b77b59 ro iommu=pt loglevel=8(axelera-env) user@r760-sales-demo:~$ axdeviceWARNING: 4PCI device count mismatch: lspci=2, triton=0

Hello Axelera team and community,We are running a Metis PCIe card (16GB, rev 02) in a Proxmox VE 9.1.9 cluster with VFIO PCIe passthrough into a KVM guest. We understand this is listed as Beta in SDK 1.6, and we want to share detailed diagnostics to help improve it.Environment:Host: Proxmox VE 9.1.9, kernel 7.0.0-3-pve (Linux 6.14), Intel VT-d enabled (intel_iommu=on iommu=pt) Metis firmware: flver=1.6.0, bcver=7.4 DKMS driver: metis-dkms=1.4.16 SDK: axelera-rt==1.6.0, axelera-runtime==1.6.0 Guest: Ubuntu 24.04.3, kernel 6.8.0-111-generic IOMMU group 22: only the Metis card (isolated, ideal for passthrough)What works (bare metal on Proxmox host):axelera.runtime Python API works perfectly on the host:ResNet18: 1.29ms per inference RetinaFace: 5.32ms

Card: AXE-BME20P1AJ04A02 (Metis 1-chip PCIe)Host: ZimaBoard 2 (Intel N150), ZimaOS (kernel 6.12.25)SDK: device-1.5.3-1, Voyager SDK v1.5 Setup: Since ZimaOS isn't officially supported, I compiled the metis driver (v1.4.4) from the DKMS package inside a Docker container matching the kernel headers, then loaded via insmod. Everything worked — axdevice showed the card at 16GiB, flver=1.2.0-rc2, bcver=1.0, clock=800MHz, all MVMs at 100%. What happened: Ran interactive_flash_update.sh inside a privileged Docker container with device passthrough.

is there any command to check vram usage on axelera metis aipu? 

Hi, I’m evaluating Metis PCIe card. It is working. I can run inference and run demo programs. But the fan is running at full speed all the time.I checked several articles in this community site and realized that BC FW must be upgraded to enable smart fan control.I confirmed the BC FW version of my card with axdevice command and it reports bcver==0.0.How can I update or flash the correct BC FW?Thanks.

I'm currently setting up the Axelera Voyager SDK on Ubuntu 22.04.5 LTS with a verified PCIe Metis AIPU card (rev 02 properly detected via lspci, and metis module loaded). However, during installation with install.sh --all --media, several symbolic link warnings occurred (e.g., media: invalid symlink), and although the runtime reports as installed, the file libaxruntime.so is missing entirely from runtime/lib/. This results in the inference script failing with: Failed to create device manager: libaxruntime.so: cannot open shared object file. Additionally, the AxInference.cpp build fails due to missing axruntime/axruntime.hpp. I’ve already tried clearing ~/.cache/axelera/ and reinstalling the runtime, but the issue persists. Would appreciate any guidance to resolve the missing runtime files and complete the setup.Thanks Pravin

Hello,I am trying to open ssh server in my Metis SBC board (with 1x AIPU, 4 GB of RAM, 16GB of host RAM and active cooling, Rev1), but right now I’m in the sh $ console with the “antelao” user, and whenever I need to run a sudo command, I’m asked to enter the sudo password, which I don’t know. Can you help me with this or point me to the right tutorial/guide?Thanks a lot

Hello everyone on the Axelera team!I'm having fun with the new Metis PCIe card that arrived!Thanks!I'm trying out voyager-sdk version 1.5.1 that supports this card, but it seems to throw an OpenCL runtime error and the sample won’t running.It doesn’t seem to be working with GST.For now, using the ‘--disable-opencl’ argument made it work.Alternatively,‘hardware_caps=config.HardwareCaps(…    opencl=config.HardwareEnable.disabel ...)source code.This isn't a solution, right?

Big update from the Metis world: the epic new 4-core PCIe card is now available to order over on the store.Huge performance shift that opens up seriously scalable edge AI.📊 Key specs: 856 TOPS (INT8) Choice of 16GB and 64GB DRAM ~12,800 FPS on ResNet-50 Runs dozens of streams or parallel models per board 30–58W typical power draw It’s not just the raw speed, it’s the ability to compress multi-camera inference, object detection, tracking, segmentation, and more into a single card that I find especially exciting. You can prototype in days, using the Voyager SDK’s YAML-based pipeline builder and model zoo (everything from YOLOv5 to sm

Radxa Orion O6 board does not boot with Metis PCIe card installed in its PCIe slot.Does not show even the BIOS screen.Tested some other cards (Intel 10GbE NICs) works all okay with the board.However, Metis PCIe card works nice with my PC and Orange Pi 5Plus board.Compatibility problem..?

Hi all,I am trying to compile a high-resolution model (1504×1504) on a Metis PCIe card, but the compilation fails due to a memory constraint:ERROR : RuntimeError: Could not find a tiling factor that fits the memory constraints l1_constraint=4011520 l2_constraint=7894528. After attempt=7 and h_size=1 and adj_factor=1, memory usage still is memory_usage={L1: {190: 141376, 193: 5017600, 191: 143360}} and per-pool memory usage {L1: 5302336}.The error indicates a required L1 size (≈5.3 MiB) exceeds the constraint (≈4.0 MiB).My questions are: Voyager SDK Solution: Is there a Voyager SDK flag or setting to adjust the tiling to overcome this ≈4 MiB L1 limit? Hardware Solution: Are there any Metis card variants (or multi-AIPU cards) that feature a larger per-core L1 cache? Any guidance on compiling this high-resolution model is appreciated. Thank you!

I’m putting an idea out to see if anyone has some data to back a theory.I’ve been talking with ​@Spanner about some problems I was having with a card, and, after looking over everything I’ve done, I’m wondering if a 75W slot is *required* rather than recommended, which would mean you need to use a PCIe x16 slot.One issue I had with the card was a small v shaped cut-out in the full height PCIe back-plate, which meant that the card wouldn’t sit fully into any PCIe x16 slot that I had (photo attached so you can see what I mean). This meant I had to use a 8x or 4x slot.Looking through the PCIe spec,

Hi, I’m trying to deploy and inference with a yolov8 segmentation model. I tried to follow the tutorial, but I just get:INFO: deploying model yolov8sseg-coco for 4 cores. This may take a while… How long should this run? I left it on for 3.5 hours and nothing happened (except the loading bar). This seems to be a model included in your library: yolov8sseg-coco.Any idea if I can turn on more extensive logging to see what is happening? Thank you in advance!  

I’m also not seeing the card recognised in `lspci`. I’m adding a post to this thread to keep all the info in one place for others, but let me know if it should be a different thread.I’ve enabled `pci-check.service` and get the following when I check the status;alsutton@svr220:~$ sudo systemctl status pcie-check.service● pcie-check.service - Check for PCIe devices with vendor ID 1f9d and reboot once if not found     Loaded: loaded (/etc/systemd/system/pcie-check.service; enabled; vendor preset: enabled)     Active: active (exited) since Wed 2025-08-06 09:33:01 UTC; 11min ago    Process: 1709 ExecStart=/usr/local/bin/check_pcie_device.sh (code=exited, status=0/SUCCESS)   Main PID: 1709 (code=exited, status=0/SUCCESS)        CPU: 6msAug 06 09:33:01 svr220 systemd[1]: Starting Check for PCIe devices with vendor ID 1f9d and reboot once if not found...Aug 06 09:33:01 svr220 check_pcie_device.sh[1709]: Reboot

Hey everyone, I’m having trouble getting my Axelera Metis PCIe AI Accelerator to be recognized by `lspci`(and my system in general). I tested the card on two different systems. On my AMD setup, I am using an AMD 5950X with an ASUS B550-F. I tried installing the card in the slot I normally use for my RTX 3080 as well as in another slot that meets the specifications. In both cases, `lspci` does not list the card even though the fan spins and I know it is getting power. Also Voyager SDK dosn’t recognize the card. I also tried it on an Intel system with an Intel i5-8500T on a Supermicro X11SCA-F motherboard. The same issue occurs. The card is powered (fan spin) but not recognized. I noticed that the boot time increases significantly when the accelerator is installed. This makes me think that UEFI might be attempting to detect something, even though no error messages are shown. As I already tried a lot and I couldn’t get it running,

Hey!PCIe card did run out of the box with a first running demo in minutes with no issues!Question: Is there a way to control the fan speed to reduce the noise of the card?Thanks!

Hi all,I am trying to enable the the usage of the Metis PCIE rev02 on RISC-V Hosts, in particular the Sifive P550.
