gpu-unlock compatibility and performance within virtualized environments using PCI passthrough.

Technical Positioning
gpu-unlock aims to extend its FP/BF16 performance unlocking capabilities to virtualized GPU setups, specifically Proxmox VMs with `vfio-pci` passthrough.
SaaS Insight & Market Implications
This compatibility report validates a significant expansion of `gpu-unlock`'s operational scope: successful deployment within a Proxmox VM using `vfio-pci` passthrough. Achieving substantial FP16, BF16, and TF32 performance gains (65-74%) in a virtualized environment is a critical milestone. This demonstrates the module's robustness even when interacting with GPUs abstracted by a hypervisor. The explicit mention of `flr bus` as the host reset method and the decision to install `gpu-unlock` only in the guest highlight specific architectural considerations for virtualization. This capability opens new market segments for `gpu-unlock`, enabling users to leverage unlocked performance in flexible, isolated VM environments, crucial for AI/ML development and deployment where resource isolation and portability are paramount.

Raw Developer Origin & Technical Request

Source Icon GitHub Issue Oct 23, 2026
Repo: Zagitta/gpu-unlock
Compatibility report: works inside a Proxmox VM (vfio-pci passthrough), Ubuntu 22.04 guest / kernel 5.15, 2x RTX 3090 — +65% FP16, +66-67% BF16, +72-74% TF32 GEMM (5.15 build fix included)

Compatibility report for a setup not covered yet: **2x RTX 3090 passed through to a Proxmox VM with vfio-pci, with gpu-unlock running inside the guest.** The guest is Ubuntu 22.04 with kernel 5.15, which needs a small build fix (patch below).

**Result:** both cards log `gpu_unlock: unlocked`, the NVIDIA driver binds normally in the guest, and there are no Xid/NVRM errors in the guest kernel log. Dense GEMM: **+65% FP16, +66-67% BF16, +72-74% TF32**, with no power cap (420 W).

## System

* **GPUs:** 2x GeForce RTX 3090 (Palit), `10de:2204`, subsystem `1569:f278`, VBIOS `94.02.42.00.9D`, power limit 420 W. PCIe Gen3 x8 each (both cards in a consumer X370 board). Host `reset_method` is `flr bus`.
* **Host:** Ryzen 9 3900X, ASUS PRIME X370-PRO (BIOS 6232).
* **Hypervisor:** Proxmox VE 9.2.2, kernel `7.0.2-6-pve`. Cards bound to `vfio-pci` via `options vfio-pci ids=10de:2204,10de:1aef`. **Nothing is installed on the host.**
* **VM:** q35, SeaBIOS, `cpu: host`, `hostpci0: 0000:08:00,pcie=1` and `hostpci1: 0000:09:00,pcie=1`. In the guest the cards are at `0000:01:00.0` and `0000:02:00.0`.
* **Guest:** Ubuntu 22.04.5, kernel `5.15.0-198-generic`, NVIDIA open kernel module `610.57.04` (from the `.run` installer, DKMS), dkms 2.8.7. No Secure Boot.
* **gpu-unlock:** `a9b0c75` (current `main`). Kernel cmdline: `gpu_unlock.targets=all`.

## Why inside the guest, not on the host

I did not try installing on the host, for this reason. When the VM starts, the host log shows each GPU reset...

I've seen some other reports that supposedly it works for AD102 as well but I don't have a card to test on myself. I'm happy to expand the allowed device IDs to AD102 as well if I see concrete evid...

This would be definetly also interesting for 4070 Ti Super, as it also uses the AD103. I have this GPU here, so I could test this if somebody gives me a small guide on what to modify and what tests...

Re-posting here rather than as a separate issue, since AD10x support was already discussed in this thread. Three AD106 cards (RTX 4060 Ti, `10de:2803`), cold boot, no driver bound, `driver=`, `stat...
