Patch for legacy driver 390.132 with Linux-5.5.x

Graphics / Linux Linux
1

I tried to build the legacy driver 390.132 with Linux kernel 5.5.2 and I get the following errors at the modpost stage:

ERROR: "nvUvmInterfaceSessionCreate" [/tmp/selfgz19699/NVIDIA-Linux-x86_64-390.132/kernel/nvidia-uvm.ko] undefined!
ERROR: "nv_kthread_q_run_self_test" [/tmp/selfgz19699/NVIDIA-Linux-x86_64-390.132/kernel/nvidia-uvm.ko] undefined!

ERROR: "nvUvmInterfacePmaUnregisterEvictionCallbacks" [/tmp/selfgz19699/NVIDIA-Linux-x86_64-390.132/kernel/nvidia-u
vm.ko] undefined!
:

and dozens of similar errors. Does anyone have a patch for this driver, please? For clarity, I cannot use the 4xx series of drivers with my GPU.

Thanks.

Edit: I went back and checked again, and do excuse me… I think the heat’s fried the last of my grey matter. This isn’t even remotely related, I think.

What distribution are you running? I’ve gone back and did a quick nm check, and the symbols seem to be exported just fine on my end. Though, I might well have missed something.

For one reason or another, the relevant uvm objects don’t get linked/found in to the kernel module. The functions in that snippet is implemented in “nv_uvm_interface.c”, and linked in nvidia.ko.

I am running opensuse Leap 15.1, but the kernel 5.5.2 is from a their newer repositories. I checked some other distributions and found a patch for Archlinux at https://git.archlinux.org/svntogit/packages.git/plain/trunk/kernel-5.5.patch?h=packages/nvidia-390xx. With a lot of modifications, I got it to build and link successfully. It seems that the main issue was that Linux-5.5 has dropped the “drm/drmP.h” header file. So they had to recreate one called “nv-drm.h” to replace it.

Now, I haven’t tried running the new kernel yet, so I don’t know if the patch will work. I wish the official driver could be patched to reflect these changes.

I have now run the Linux-5.5.2 kernel with the patched nvidia driver. It appears to work, but there is a hidden issue somewhere (which hasn’t crashed my system so far). The kernel logs show the following:

Perhaps someone might have some insight into this issue?

I have applied different versions of this patch, which have different structures but actually end up with the same transformations of the files. Needless to say, they achieve precisely the same results. Just to reiterate, the driver does appear to work but the errors persist in the logs, i.e.

refcount_t: underflow; use-after-free.

So far, it hasn’t caused any harm. I just wonder what it means?

I confirm I can no more use 390.132 drivers with kernel 5.5 in Fedora. I have to freeze the kernel at 5.4.18. I found some more info here 5536 – The Nvidia-390xx driver module is not going to be installed on the new 5.5.5 kernel and here Nvidia 390 drivers stopped working with kernel 5.5 and probably also Nvidia 340 - Ask Fedora

My GeForce GT 730 is not supported by 440xx drivers. The link above say 340xx drivers also may be affected. What are my perspectives if I cannot go to kernel 5.5 and above? I will not be able to upgrade distributive to next version?

8

Additionally, Nvidia website disinforms about my card. At 440.59 page there are “SUPPORTED PRODUCTS” list, and I see there “GeForce 700 Series” and “GeForce GT 730” there: Linux x64 (AMD64/EM64T) Display Driver | 440.59 | Linux 64-bit | NVIDIA

But in fact no! This is a mistake. When I install 440 drivers at “GeForce GT 730”, they say they will “ignore my GPU” and NOT WORKING despite the list say it will work.

In what way has the driver stopped working? As in, you’re unable to compile the driver for 5.5?

As far as I can see, Arch Linux has a package compatible with 5.5. The patch they bundle is the one that “fixes” the missing drmP.h header. Another user on the forums said that PRIME Synchronisation stopped working, and that the one I posted in there apparent got it working again, also on 5.5:
https://bbs.archlinux.org/viewtopic.php?pid=1888542#p1888542

Manjaro apparently got it to compile with 5.5 (and 5.6, I think) as well, though I’m not sure what, if any, patches they used.

The underflow issue was a kernel bug, and got fixed in 5.5.6 if I’m not misremembering.

10

I don’compile drivers and install “akmod-nvidia-390xx.x86_64” from Fedora repositories. When kernel updated from 5.4.18 to 5.5.5, system went to fallback to Nouveau drivers, loaded GUI with low screen resolution. Only going back to kernel 5.4.18 returned to normal.

11

Kernel 5.5.6 was published in Fedora repo, I tried it, no luck. Maybe meant kernel 5.6?

12

I went and looked for the mailing list thread I remembered reading up on it, but can not currently find it. Either I misremembered, or it was somewhere else I got the information from and that was incorrect; or, indeed, it was 5.6 the fix was queued for.

In either case, the issue with actually getting the driver to compile is separate from the non-fatal “refcount_t: underflow; use-after-free”-warning that some people are getting. That’s an issue users of 390xx, 440xx, and possibly other versions as well, are getting. No new kernel release can fix that.

Lastly, I looked at the RPMFusion bug report and saw the current maintainer has dropped the package, so you’re definitely going to have to stay on 5.4 for the foreseeable future – at least, until NVIDIA or someone else patches and packages the driver. I actually gave it a shot myself on a virtual Fedora box, but couldn’t quite get a grip on the RPM packaging system, so that task will have to be something for another better skilled person, I’m afraid.

13

I now have kernel-5.5.6 (from openSUSE) and I can confirm that that I was able to compile the driver (with patches applied) for this kernel version. It works just the same as in kernel-5.5.2 with the same warnings (refcount_t: underflow …) and all. So the kernel wasn’t fixed and I imagine these warning can be ignored safely.

14

Just for reference, Nvidia is depreciating several drivers, including 440.33.01, which is the driver used in their CUDA development toolkit. These drivers will no longer work beyond the 5.4 Kernel.

15

I suppose, I only now have to wish if the NVidia words that latest drivers (not 390) support my card were true.

The page for 440.59 Linux x64 (AMD64/EM64T) Display Driver | 440.59 | Linux 64-bit | NVIDIA in “SUPPORTED PRODUCTS” lists “GeForce 700 Series:” and then “GeForce GT 730”

In fact this is false. 440.59 not working with my “GeForce GT 730”.

I see there is newest 440.64 Linux x64 (AMD64/EM64T) Display Driver | 440.64 | Linux 64-bit | NVIDIA which also list my card. I didn’t check it yet (but little hope)

Patch for Fedora akmod-nvidia-390xx-390.132-4.fc31.x86_64 applied and works with kernel 5.5.8-200.fc31.x86_64: 5536 – The Nvidia-390xx driver module is not going to be installed on the new 5.5.5 kernel
