Kernel 4.16-rc1 Breaks latest drivers - 'Unknown symbol swiotlb_map_sg_attrs'

With Kernel 4.16-rc1, the latest NVIDIA drivers - 384.111 and 390.25 - both compile OK, but then fail to load/run:

modprobe: ERROR: could not insert ‘nvidia’: Unknown symbol in module, or unknown parameter (see dmesg)

dmesg:
[ 2142.352238] nvidia: Unknown symbol swiotlb_map_sg_attrs (err 0)

This symbol is no longer exported, since 4.16-rc1… (and thanks to Michal Kubeček for pointing out the relevant commit…)

[PATCH 11/22] swiotlb: remove various exports

Robert Gadsdon
rglinuxtech.com

I’d like to confirm this exists on my system as well, very problematic since a competitor’s CPU product I’m using is only stable with this kernel, and at the same time I have an nvidia GPU I wish to use in said system.

Nobody is using this symbol apparently.

EDIT: Reported to the kernel team https://bugzilla.kernel.org/show_bug.cgi?id=198997

The missing exports are not the only problem.
I have build a kernel 4.16-rc4 with reverted commit, but nvidia doesn’t work at all.
There will be a kernel oops and not starting X.

So there are more problems in 4.16 than the missing symbols.

Thanks towo. Reposted your logs on the kernel bug report. https://bugzilla.kernel.org/show_bug.cgi?id=198997

The kernel team have marked the bug priority one.

This patch does work for me (x64 only, no spectre/meltdown mitigation enabled):
The driver uses this one symbol just to detect wheter swiotlb is really in use,
you can just ignore the whole path and just return that swiotlb isn’t used.

Now i have done another test, new kernel build with CONFIG_HARDENED_USERCOPY_FALLBACK=y and the reverted commit e64b9562ba281dc1dc613408707375cb9c5660e5, now X is starting and seems to work.

@mlau, Many thanks for the patch!

For 384.111 I had to increment the line number references by 100 to make it work, (so ‘…-1209,6 +1209,7…’ becomes ‘…-1309,6 +1309,7…’, etc.) but have tested this, and the NVIDIA driver compiles/loads OK, and runs OK, so far… (tested with Kernel 4.16-rc4, nopti, patched driver 384.111, on Fedora 27 with KDE/Plasma, and VMware 4.1.1)

Robert Gadsdon
rglinuxtech.com

so what could be a good fix for this and the 4.15.x kernel?
I ran across this

https://www.if-not-true-then-false.com/2015/fedora-nvidia-guide/

thanks
Matt

Finally linux kernel 4.16.0 has been released. So many distribution will release 4.16 kernel packages. Please hurry up!

Regards,

Hello,

I wanted to add here that I saw the same

Unknown symbol swiotlb_map_sg_attrs

issue from nvidia.ko(NVIDIA 390.42 GeForce GTX 860M driver) for the latest stable
4.16(https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.16.tar.xz). At first I thought, the

lib/swiotlb.c(which has swiotlb_map_sg_attrs() function)

was not built during the kernel build, so I explicitly cleaned and built

linux-4.16/lib/* directory(CONFIG_SWIOTLB enabled as well in kernel config)

and installed the kernel modules from therein onto the system

(/lib/modules/4.16.0/...)

.
Even then, nvidia.ko complained it couldn’t find swiotlb_map_sg_attrs(symbol). Then I
checked whether swiotlb_map_sg_attrs symbol was shown as defined(T) in any of the

linux-4.16/lib/*.ko(using nm tool)

None of them showed swiotlb_map_sg_attrs to be defined within them. So, that made me think
this swiotlb_map_sg_attrs symbol visibility might have changed in the latest 4.16 but it was
visible/exported in earlier kernels(4.15.15, 4.15.14, etc - for which I had no issues in
building, installing and using the same NVIDIA 390.42 GeForce GTX 860M driver). So, as
per one of the above comments, I disabled the logic which refers

swiotlb_map_sg_attrs in common/inc/nv-linux.h

and made the nv_dma_maps_swiotlb() to return NV_FALSE as swiotlb is not used anyway. Rebuilt

NVIDIA 390.42 GeForce GTX 860M driver

Installed, loaded the nvidia*.ko modules and that worked and is working without any issues
for the latest stable Linux kernel 4.16 for Ubuntu 17.10 x86_64.

Below are the specifics.

By the way, in the above whole experience, I am using

clang/LLVM as the compiler/toolchain to build NVIDIA 390.42 GeForce GTX 860M driver(latest as of now)

and also

Linux kernel 4.16(and the earlier kernels : 4.15.7 and above) is being built by me using clang/LLVM

.
For any one interested in this clang/LLVM related kernel/NVIDIA driver details, I have written a report here –

Success : Ubuntu 17.10 x86_64 on LLVM/clang-built kernel with Nvidia 390.25 driver : 
<a target='_blank' rel='noopener noreferrer' href='https://ubuntuforums.org/showthread.php?t=2386423'>https://ubuntuforums.org/showthread.php?t=2386423</a>

Cheers.

UPDATE : Above logic of disabling swiotlb specific code worked even with latest Nvidia v390.48 driver for Nvidia GeForce GTX 860M graphics card.

On Fedora 27, I compiled 4.16 with the default .config (copied from /boot/config-4.15.13-300.fc27.x86_64) modified so that no default drm except for xfree86 drm were included.

Then I got a kernel with System.map including swiotlb_map_sg_attrs,

$ grep swiotlb_map_sg_attrs /boot/System.map
ffffffff81458640 T swiotlb_map_sg_attrs
ffffffff815294c0 t xen_swiotlb_map_sg_attrs

but NVIDIA driver failed to compile. Why?

This breaks Ubuntu 16.04 (and I suppose all others too) when installing kernel 4.16.

The patch from mlau worked fine for me - Fedora 25 + kernel 4.16.0 rc7 fc28

Same problem here on Gentoo, kernel 4.16.1, Nvidia driver 390.48

Gentoo, on 4.16.1 and drivers version 390.48. mlau’s patch (post #6) works for me.

opensuse tumbleweed recent update to 4.16 broke nvidia driver
please, fix it
mlau’s patch works, btw. thank you!

I have a similar problem on Slackware 14.2, kernel 4.16 (but also previous), driver 390.48 (but also previous).

The installation fails and the log is attached.

Any ideas?

Driver 396.18 works with kernel 4.16 ootb.

Where do I find it? The driver download page gives me the 390.48.
