GNU/Linux Debian 11 nvidia-drm driver errors (version 470.57.02)

Hello, I’m currently using an Nvidia GeForce GTX 1660 Ti with proprietary drivers on my laptop (+ Intel GPU, PRIME render offload enabled and functional) and systematically at boot time, I get the following errors:

This sequence of errors also happen some time after the boot, but I haven’t been able to identify their cause. I also precise I’m currently running a Linux 5.10.0-8-amd64 x86_64 kernel, my distribution is Debian (bookworm/sid) and, as stated in title, Nvidia drivers version is 470.57.02. Also, more recently appeared the similar error message:

sept. 25 18:09:07 xxxxxxxx kernel: [drm:nv_drm_gem_export_nvkms_memory_ioctl [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to lookup NVKMS gem object for export: 0x00000001

These messages appeared a few months ago, I reported it on thread GNU/Linux Debian 11 nvidia-drm driver errors (version 460.73.01) to no avail so far.

And occasionally, I notice a crash of the nvidia-drm driver, which did not occur before the error messages.

Hello, after a quick look at the code, it seems both error messages are caused by a failure of function nv_drm_gem_object_lookup(), defined as an inline function in header file /usr/src/nvidia-current-470.57.02/nvidia-drm/nvidia-drm-gem.h. Could it be possible to get some idea on the nature of a “gem object”. Is it something required or even available on this GPU model ? If not, is it really necessary to use ERROR level for this message ? Or could I safely lower the log level and discard it as a simple warning ? Otherwise, the function nv_drm_gem_object_lookup() is calling to_nv_gem_object(). However, a function with the same name (but different parameters and order of parameters) is chosen at compile-time by cpp depending on the value of NV_DRM_GEM_OBJECT_LOOKUP_ARGUMENT_COUNT. But I did not find out where it was defined. This mechanism seems more fragile and error-prone than a variadic function. Would it be possible to know which one of them is supposed to be called in the current context ?

And by the way, the build triggered by a dpkg-reconfigure nvidia-kernel-dkms is failing for kernel 5.14.0-1-amd64:

Building initial module for 5.14.0-1-amd64
Error! Bad return status for module build on kernel: 5.14.0-1-amd64 (x86_64)
Consult /var/lib/dkms/nvidia-current/470.57.02/build/make.log for more information.

After a look at /var/lib/dkms/nvidia-current/470.57.02/build/make.log it seems we have a recurring error:

I had to make the change in /usr/src/nvidia-current-470.57.02/common/inc/nv-time.h but of course, it breaks the build for the old 5.10 kernel unless using some #ifdef. And taking into account the fact that there is no pci_dev pointer anymore in struct drm_device (check file /usr/src/linux-headers-5.14.0-1-common/include/drm/drm_device.h). I can provide a patch if you want, it allows building Nvidia drivers from sources but still, the issue reported above remains.

FYI, it seems I’ve got plenty of i915 gem objects, whatever they are:

So it seems those «Failed to lookup gem object» do not really deserve the level of ERROR on configurations with two GPUs, which is relatively common for laptops nowadays. Unless of course there is an issue no one seems eager to fix, as long as it’s not reported by more people. Anyway, I sent the nvidia-bug-report to someone on your team…

Hello, since installation of Nvidia drivers version 470.74, the following errors are still occuring at boot time and some time after. Still using Linux kernel 5.14.0-2-amd64 x86_64, intel driver iHD (kernel module i915) and PRIME render offload.

Hello, now using Nvidia proprietary driver version 470.82.00, kernel 5.14.0-2-amd64 (distribution Debian bookworm/sid). Also using GNOME and media players with PRIME render offload. The issue is still there:

$ sudo dmesg |grep "Failed to lookup NVKMS gem object" |wc -l
67

The 67 messages are for a relatively short uptime of a few hours. By the way, it seems I’m not the only one seeing this error message, for instance see this thread or this one. Is there a threshold over which we can expect some feedback ?

Yes, indeed. Although Nvidia opened a good chunk of their source code. Is it really that faster on Windows ? I thought PRIME render offload was close to the mechanism used on Windows (for dual GPU systems). Anyway it does not work exactly the same with every media player. For instance with VLC I can benefit from PRIME render offload but I don’t get hardware acceleration on iGPU, whereas with mpv I get both.
-------- Message d’origine --------

Im really sure that the nvidia drivers for Linux are better than for those for windows,but maybe it depends about the o.s used.

everytime I open VLC 3.0.16

Same here with VLC, but also with mpv. More and more error logs with each new Nvidia driver version (currently 33 identical error lines). The sequence of errors at boot time is slightly different, i.e. Failed to lookup gem object for fence attach instead of Failed to lookup NVKMS gem object for export but both come from nvidia-drm kernel module.
