Hi.

I've just read regular @world build log and found this:

I'm very surprised because I have GTX 1080 GPU:

> # lspci | fgrep VGA
> 42:00.0 VGA compatible controller: NVIDIA Corporation GP104 [GeForce

Is this some kind of maintainer's mistake or does NVIDIA really messed 
up with drivers again?

It looks to me like the 396 versions of nvidia-drivers is not compatible
with your card.  Most likely, you have to stick with the 391 series.  I
for example have a older card that requires the 340 series.  I have to
mask anything above that.  You for example may need to mask anything 396
or above. 

You should be able to go to the nvidia website and find out exactly what
series of drivers you need and then mask anything above that.  Once that
is done, you shouldn't have this problem again.

Hope that helps.

Hi Dale,

I was also hit by this message...

For me it looks like that sticking to a certain version of the
nvidia-drivers will also bind me to an - then older - kernel version.

In my case I would be bound to the 390.* versions of that drivers.
This drivers compile fine with the linux-kernel 4.16.2 ... but the
boot throws me back to the console.

dmesg shows this then:
[   32.227140] nvidia: Unknown symbol swiotlb_map_sg_attrs (err 0)
[   32.281875] nvidia: Unknown symbol swiotlb_map_sg_attrs (err 0)

Do I really need to buy a new nvidia card (I am using Blender a lot)
just to be able to update the kernel??

Slightly alarmed

I'm not sure on having to buy a new card.  Mine is older, GT220 BUT I'm
still using kernel version 4.5.2.  I've got a newer kernel available, I
just haven't rebooted in many months.  I just tried, the version I'm
using won't build with newer kernels, 4.9.34.  So, you have a
interesting question. 

I seem to recall having to set up a overlay for a slightly older version
because the newer version for my series would build with current 4.5
kernel but my screen was all messed up.  I had trouble getting logged in
so that I could kill X to even get the console to work.  So I'm using a
version of nvidia that isn't even in the tree any longer as it is. 

I may have to check into this more later.  Funny thing is, I was looking
at newer video cards just the other day.  I was just wanting a spare, in
case the current one burnt out.  I wasn't thinking about the software
not working.

Hi Dale,

hmmmm...sticking to old cards has a couple of drawbacks in my case:
-- I am using Blender a lot. Blender loves CUDA (and recentlu becomes
   better with AMD cards, which has more to do with AMD than with
   Blender as far as I can remember) to render on the GPU instead
   with CPU, which is much more faster. Even Blender becomes more
   power hungry (CPU power, not necessarily electrical power ;)
   because it get more and more features (Physical based shading
   technics for example). So from time to time I need a new
   graphics card.
   But I dont like it if nvidia is dictating me what to buy when.
   The opensourced nvidia driver of the kernel by far is not that 
   capable when it comes to GPU rendering as far as I know. So no option here.

-- Not only because of meltdown and spectre I dont want to stick
   with old kernels. As the kernel is the heart of my system, I 
   want to update the kernel as soon as possible. Due the problem
   with the nvidia-drivers currentlu I am urged to stick with
   linux-15.15 currently.

-- I have two graphic cards in my system:
    NVIDIA Corporation GM206 [GeForce GTX 960] (rev a1)
    NVIDIA Corporation GF108 [GeForce GT 430] (rev a1)
   The smaller one is for the desktop, the newer one for rendering.
   If one renders with the same card as being used for the desktop,
   it makes the desktop quite stuttering while a render process is
   running.
   Rendering animations can take HOURS...
   The GT 430 seems to cause the driver problem...

BUT: The older driver does not work with the newer kernel
(linux.4.16.*)

The GTX960 is "too powerful" to be used for desktop perposes only
(I am no gamer and using a simple windowmanager (openbox) without any
graphical gimmicks or gadgets.)

Problem: Buying another "small card" will present me the same
situation too soon again.
A bigger, newer card than the GTX960 will give me lot of render
power (good!), but overfeatures my desktop (the GTX960 will feed
my desktop then) Its like buying a ROLEX just for the purpose of knowing 
the time.
(Hrmmm....wait....A ROLEX *is* displaying the time only....it semms that
I have a misconception of the usage purpose of a ROLEX...may be ;) )
Not comparing a GTX 960 with a ROLEX here...

The whole situation is ,,, [CENSORED].

"Software is buyong hardware."
The last time I heard of that was in the context of Windows.
Didn't thought, that Linux will present it to me one day.

DAMN!
sorry

Before updating the nvidia driver, you should always check here:

   http://www.nvidia.com/Download/Find.aspx

and see if the version you're updating to is a beta driver or not.

As a long time nvidia-drivers user, I really recommend to:

   1. Use an LTS kernel series (latest LTS series is 4.14.x.)
   2. Do not install nvidia beta drivers.
   3. Do not use X.Org pre-releases.

Currently, that means these in package.mask:

   >=sys-kernel/gentoo-sources-4.15
   >=x11-drivers/nvidia-drivers-391
   >=x11-base/xorg-server-1.19.99

Unless you're using Chrome, where 390 has a bug that makes it unusable 
slow, so you need:

   >=x11-drivers/nvidia-drivers-385

You need to check on the available versions these packages manually from 
time to time to see if it's safe to update them.

Also, nvidia driver version can be confusing. 390 is the latest stable 
series, while 384 is the "LTS-like" stable series. To be frank, I find 
it impossible to tell what's happening with driver releases from nvidia 
if I don't read phoronix.com news.

In any event, the TL;DR is that sticking to non-beta drivers and 
non-beta xorg and the latest LTS kernel will result in avoiding the 
majority of breakages.

hi Alexey,

which in turn is, what I said before:
I will be bound to older versions of software.
It is, what I try to avoid.

Do you have something specific in mind? I'm not aware of software that 
requires a non-LTS kernel right now, or a beta X.Org driver, or a beta 
nvidia-driver.

LTS kernels are maintained, so they get all the required patches.

It's an LTS kernel. "Long-Term Support." It gets all the security fixes 
and bugfixes for years to come, while kernels like 4.15 and 4.16 will 
stop getting updated after a short while. LTS kernels on the other hand 
are updated for years.

Yes I've checked. That's why I was surprised by Portage build log. I 
didn't build nvidia-drivers manually for a long time and do not remember 
where this GPU checks are (ebuild or driver package).

I didn't think that this driver will not work with my GPU. I was 
confused by the message and wanted to report. If it's ebuild-side 
problem then must I create an issue in the Bugzilla?

This seems to be a bug in the nvida-drivers.eclass file. I have the
same card, and it is NOT going out of support now. If you look at the
link from the ebuild error message, our card is not one of the cards
on any of the "legacy cards" lists. If you search for drivers on
https://www.geforce.com/drivers you will see that this new beta driver
is available for our card.

I'm not sure if this bug is because the eclass checks these cards
against any version higher than 391 and complains, in which case
*everyone* will get the error message, or if something else is going
on, but I feel confident that this driver should work fine for you
(consider that it's a beta driver though).

Hi.

I've just read regular @world build log and found this:

I'm very surprised because I have GTX 1080 GPU:

Is this some kind of maintainer's mistake or does NVIDIA really messed 
up with drivers again?
