Hi guys,

I’m having an issue with my nvidia drivers under kernel \>=6.5.  
Tested and confirmed with kernel 6.6 and 6.7.

It’s not nvidia-drivers version dependant, tested with 535.x series and 550.x series.  
I don’t have any issue while using 6.4 kernel.

**Here some infos :**

Looks like you’re using the nvidia-open driver. Please switch to the non -open driver and retest.

Hello,  
Maybe it was the wrong one, I tried the open driver.

Please note it’s a Lenovo 15IAH7H, with integrated intel GPU + Discrete RTX 3060. I’ve just updated Vbios :

Tried again with non open on 6.7 kernel series :

Hello again,  
I can confirm the regression, was able to isolate the issue came between 6.4.16 (last working and latest on [kernel.org](http://kernel.org)) and 6.5.1.

Here my kernel config if needed : [## Automatically generated file; DO NOT EDIT.# Linux/x86 6.4.16-gentoo Kerne - Pastebin.com](https://pastebin.com/c65KxZQF)

Can please any dev check this issue ? I’m able to make some tests for you if needed

Should not have an influence on the nvidia gpu but your i915 fw is missing.

Regarding the nvidia gpu, something seems to be wrong regarding rBAR, lspci reports

```auto
Region 1: Memory at 6000000000 (64-bit, prefetchable) [size=256M]
[...]
BAR 1: current size: 8GB, supported: 64MB 128MB 256MB 512MB 1GB 2GB 4GB 8GB

```

256MB != 8GB

On kernel 6.8, there’s a link failure detected (for whatever reasons) and the link is retrained on the upstream bridge:

```auto
[0.521517] pci 0000:00:01.0: broken device, retraining non-functional downstream link at 2.5GT/s

```

I suspect this breaks resource allocation in regard to resizable bar so the nvidia gpu ends up defunct.  
The code to retrain was added to the kernel around kernel 6.5 to [drivers](https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers?h=v6.8.3)/[pci](https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/pci?h=v6.8.3)/[quirks.c](https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/pci/quirks.c?h=v6.8.3)

You could change `bool pcie_failed_link_retrain(struct pci_dev *dev)` to just return true and recompile the kernel to check if my suspicion is correct. Otherwise, I guess you’ll have to bisect the kernel.

Hello,  
Nice suspicion mate. I patched as your idea, and it’s working again on 6.8 kernel with a few warnings.

```

Now we need to find something less ugly to fix it, any idea ?

But still not working correctly. I tried to start a game to test the GPU (CS2), game is freezing as soon as started.

For your intel igpu, you’ll need to add the firmware to the kernel image when running without an initrd. Setting  
CONFIG\_EXTRA\_FIRMWARE  
to  
`i915/adlp_dmc_ver2_16.bin i915/adlp_guc_70.1.1.bin`  
and  
CONFIG\_EXTRA\_FIRMWARE\_DIR  
to  
`/lib/firmware`  
should be necessary.

I added the intel GPU firmwares but I got a LOT of issue (screen blinking/black screen etc).  
After some work I finally give up using the xf86-intel drivers and switch to the modesettings drivers.  
It fixes quite all issues with intel firmwares.

Here are nvidia-bug-reports WITH quirks.c patched :

I can use nvidia-drivers without issue on 6.5 in this case, but game freezing on 6.8. I don’t know if this issue is related or not…

The “Intel” driver is broken and shouldn’t be used on meodern hardware, modesetting is the correct driver. You now set an intel-only config, so the nvidia driver isn’t used at all. Please delete /etc/X11/xorg.conf.d/20-modesetting.conf  
After reboot, the nvidia gpu should be in offload mode, run somethin on it by prepending  
` __NV_PRIME_RENDER_OFFLOAD=1__ GLX_VENDOR_LIBRARY_NAME=nvidia`

I can’t try removing modesettings.conf at the moment, but I think you’re guessing it because the nvidia module wasn’t re-compiled before starting X. I re-compile & modprobe it after X start. I can confirm I also used the nvidia gpu (my CS2 game was running on nvidia GPU : confirmed with nvidia-smi).

I attached a glxinfo as example.  
\_\_NV\_PRIME\_RENDER\_OFFLOAD=1 \_\_GLX\_VENDOR\_LIBRARY\_NAME=nvidia glxinfo
