eGpu
En anglais “GPU enclosures”. Nécessite un port Thunderbolt 3, 4 ou à venir 5.
Mes expériences eGpu avec mon Mint 21.3 (Ubuntu 22.04) kernel 6.8.
- WKGL17 Wikingoo
- acheté
- ✅ RTX 3060 ok
- ✗ RTX 5060 à peu près ok (ça plante selon les modèles)
- WKG-L19C70 Wikingoo
- Le vendeur dit qu'elle fonctionnera mieux que la L17 avec la RTX 5060 …
-
- acheté
- attention, une fois trouver la bonne position ne plus rien bouger.
- ✅ RTX 3060 ok
- ❌ RTX 5060 failed
- ADT UT4G
- USB4/TB3/T4B to Pcie X16 adapter for eGPU
-
- ADT UT4G-BK7 TB3/TB4 vers PCIe x16 PCIe 4.0 x4 GPU Dock
- AOOSTAR
- AG02 Oculink/USB4, avec PSU
- AOOSTAR EG02 TB5+Oculink
Au final on ne fait tourner que de petits models avec de petit context …

NVidia Driver Installation Guide
- nvidiafb: framebuffer support
- nvidia_modeset: Kernel Mode Setting (KMS) support
- nvidia_uvm: Unified Virtual Memory (UVM) support
- nvidia_drm: Direct Rendering Management (DRM) support
Après plantage du driver ou CUDA, essayer de le décharger avec:
# Ça fonctionne car driver nvidia non attaché à X11 # grâce à `blacklist nvidia-drm` et `options nvidia-drm modeset=0 fbdev=0` dans `/etc/modprobe.d/...` sudo modprobe -r nvidia_drm nvidia_uvm nvidia_modeset nvidia # Le driver est bien chargé au prochain usage, et CUDA fonctionne kernel: NVRM: loading NVIDIA UNIX Open Kernel Module for x86_64 580.105.08

J'ai du mal avec cette carte:
- avec le bridge PCIe/THB Cyid TB3-HL7 (JHL7540) : Échec complet
- avec le bridge PCIe/THB Wikingoo WKGL17-C50 : Carte reconnue et llama-bench fonctionne
- par contre l'ensemble n'est pas stable, ça plante sans prévenir, souvent éteindre de force le laptop …
Ticket ouvert chez Nvidia : kgspBootstrap_GH100: GSP-FMC reported an error while attempting to boot GSP
J'ai acheté un câble Thunderbolt certifié (50€) pour remplacer celui fourni avec l'eGPU. On dirait que ça fonctionne mieux, mais ça plante facilement kernel: NVRM: nvAssertOkFailedNoLog: Assertion failed: GPU lost from the bus [NV_ERR_GPU_IS_LOST] (0x0000000F) returned from pRmApi→Control() … NVRM: nvGpuOpsReportFatalError: uvm encountered global fatal error 0x60, requiring os reboot to recover …
