Nvidia drivers and 2.6.x kernel

Nvidia drivers and 2.6.x kernel

[Christian Unger]

Hi Everyone

I'm not sure if this has been done to death or not, but i can not get the 4496 
and 5328 versions of the NVidia kernel to work on the 2.6.1 version of (you 
guessed it) Linux.

I've googled about but not really found any great stuff. I did find this:

http://www.kerneltrap.org/node/view/1804
and from there the link to http://minion.de

I've tried it with both versions of the driver, with both versions of the 
drivers Makefile (Makefile.nvidia and Makefile.kbuild). 

With the installer and with just make install (make kernel_module_install).
The message i get is that the module is the wrong format.
The files that i can get to appear in:
/lib/modules/2.6.1/kernel/drivers/video are nvidia.ko & nvidia.o
Originally i thought they were the same file, but they have different sizes 
(afterall)
chakkerz@stormcrow:/lib/modules/2.6.1/kernel/drivers/video$ ls -l
total 4648
-rw-rw-r--    1 root     root      2376880 Jan 21 12:14 nvidia.ko
-rw-rw-r--    1 root     root      2376702 Jan 21 12:15 nvidia.o

so: i've tried unpatched, patched, old and new drivers, installer and make, 
make in the installers root, and it's sub director usr/src/nv ... oh yes, and 
different versions of the patch.

could someone please tell me where to find out how to make this work, because 
linux without GUI is little use to me.

In case it matters:
This is an AMD Athlon XP 2800+ on a Gigabyte GA-7N400 Pro2 MoBo (nforce2). The 
FFX is an Abit Siluro GeForce 4 Ti4200 OTES. 2 sticks of 256 Corsair DDR in 
dual channel. The kernel compiles i tried were with AGPGART integrated (and 
the nforce/nforce2 also integrated) as well as AGPGART as a module. Most of 
the stuff i tried with AGPGART as a module.

Well ... i've applied the patch and downloaded the pre-patched drivers, 
sacrificed a virgin, installed the module loading stuff (just in case) and 
still no joy. 

So i think the fault is not with NVidia. or the patch. Maybe it's a flaw in 
Slackware 9.1, or i'm just too thick. 

I did get X to work with nv, but since i have a dodgy old monitor i can't get 
the vertical alignment right (there probably is a way to do it -- SAX in SuSE 
does the trick).

How strange. I run slack 9.1 and 2.6.1, just grabbed the 4496 
pre-patched file from http://www.sh.nu/download/nvidia/ and installed it 
as I would on 2.4. Works a charm.

Hmm ... that does worry me a little then ... as there then is absolutely NO 
reason for it not to work. 

Maybe the virgin was not pure enough ... :)

Would you be able to possibly mail me a copy of your kernel configuration 
file. In case i mucked something in it up .... i can't imagine what ... but 
still if you could forward me a copy of the file, i'll try that.

Re: Nvidia drivers and 2.6.x kernel

[Christian Unger]

Kieran (et al)

Ok i tried the configuration you sent, and after working out that you have a 
different motherboard chipset which caused the kernel to hang here whenever i 
did anything that involved the hard disk (copy the drivers from my backup 
partition to my work partition for instance - to ensure that i was using 
"good copies") i even had signs of success.

Mere signs though. I continue being told it's an invalid format:
FATAL: Error inserting nvidia (/lib/modules/2.6.1/kernel/drivers/video/
nvidia.ko): Invalid module format

So ... i'm out of ideas ... i don't get why it ain't doing for me what it is 
doing for everyone else. I am wondering IF something screwed up when i 
upgraded Slackware 9.1 from 9.0 ... and in the interest of testing that 
theory might do a rm -f / later and start from scratch. I haven't decided if 
2.6 is worth that much yet though.

nVidia has released drivers supporting kernel 2.6 on their website.

They run nicely for me.

Hmmm... why do people say "they" when talking about a "driver"?

nVidia driver uses far less memory now, was Re: Nvidia drivers and 2.6.x kernel

Followup note: Running the new nVidia drivers, I see a huge drop in the
size of the X server.

My normal X server virgual memory size was around 260MB.  If I played a
game like Infiltration, it would rise to 300MB.  After exiting the game,
the virtual size stayed where it was.  It never shrunk, and it ate a lot
of swap space too.

Then I upgraded to the new nVidia drivers which support the 2.6 kernel,
and things have changed.

I noticed my system was swapping a lot less, but didn't have time to
look into it.

Today I did.

My X server now hovers around 76MB, virtual size. Loading Infiltration
causes it to grow to around 98MB.  When I exit the game, it drops back
down to 76MB virtual.

It also seems to release memory after a program like The Gimp has been
running, though I've done less testing with that.  I've observed a
110MB->78MB drop when exiting The Gimp, but didn't record the event.

Wow... I started out on 8-bit micros, and talking about "drops" of 32MB
amazes me sometimes.

Questions:

Is the new driver able to hide the graphics aperature, showing a more
true statistic on memory use?

Was the 2.6 kernel always capable of showing the right thing, and the
new driver being made for 2.6 is just working better?

Why does the virtual memory size shrink now?  Could the new driver be
unmapping vitual memory to free it up?

I'm going to ask nVidia, but wanted to post here and also see if anyone
else noticed this.

How's the performance?

I have found the 4496 and 5328 drivers lowered my performance.

5328 is supposed to be faster mip-mapping and faster when running with
vertical blank sync, but I didn't see it myself.  It also caused quite a
few sound artifacts from my Live! sound card.

Anyone done a driver-by-driver benchmark?

I got tired of it, but here's the performance order on my system from
fastest to slowest:

4620
3xxx (last stable 3xxx driver)
4496
5328

Mostly what I look for are not benchmark numbers, but notable hesitation
in programs and interactive response, and side effects like bad sound
artifacts.

pci_alloc_consistent()

[Leonid Grossman]

Are there any known issues with pci_alloc_consistent() allocating more
than 1MB?
One of our developers seems to recall a thread but we can't find it...

We are using pci_alloc_consistent() in our 10GbE driver, to allocate
memory for DMA transfers between
host and device. 
If we allocate under 1MB, everything works fine. When the allocation is
more than 1 MB, allocation call does not return any failure but some
data corruption seems to take place beyond the 1 MB space. 

Is this a known problem? The system is 2-way Itanium, running 2.4.21
kernel.

Thanks in advance, Leonid

Leonid,

What type of Itanium box? It's possible what you're seeing is caused
by a bug in the IOMMU code, but we would need to know which one (HP,
SGI or someone else's).

The problem with pci_alloc_consistent()above 1MB happens on HP rx2600
(this is 2U dual-Itanium 900MHz pci-x 133 box). I don't believe it
happens on 64 bit Opterons. Today we are going to test Dell and SGI
Itanium systems, as well as a bit newer rx 2600 with Itanium-2 1.5GHz -
I'll let you know by the end of the day.

Thanks, Leonid

   The iommu code on zx1 boxes is currently limited to consistent
mappings of 64 * PAGE_SIZE.  We need to implement the consistent dma
mask interface so that 64bit devices can bypass the iommu and dma as
much as they'd like.  If you change your system page size to 64k, you
should be able to get up to 4MB mappings with the current code.  Sounds
like we need to do a BUG or something to make it more obvious how this
is failing.  It should be a pretty simple update to sba_iommu to make it
start looking at consistent_dma_mask in this path.  I'll try to get a
patch sent out for it on 2.6.  Thanks,

	Alex

I have no problem myself.

I use the driver *.run files that have been patched to work with 2.6 
kernels.

I don't have to build a thing, I just install them like I would under
kernel 2.4.

If you look at the minion website, there is a mirror in the download
list, and that mirror has install packages modified for 2.6.

It's completely automatic.

Maybe you should try that.

It will fail when it goes to the nvidia website to find precompiled glue
code, and then proceed to build the glue locally.

NVidia does. Check the download link for Linux/FreeBSD drivers and in particular the link to the Nvidial Linux forum.

Did you try the installers from http://www.sh.nu/download/nvidia/ ?
 http://minion.de refers to them, and they appear to work fine here.

Wrong (or no) module-init-tools?  Mine currently is 
module-init-tools-3.0-0.pre5.2mdk from the Mandrake cooker, although I've not 
had trouble for some time with any version.  The nvidia.ko file is the one 
that will load under a 2.6 kernel.  The wrong format message sounds like you 
don't have module-init-tools installed, although I would expect getting your 
nvidia card to run would be the least of your problems.

You could also switch over in your XFConfig-4 to the nv driver that is part of 
the kernel build.  That should get your system running with X, letting you 
solve the nvidia driver problems later.

What messages do you get about what is going wrong?  What happens when you so 
a modprobe nvidia?  What does your log file from XFree show?

About module-init-tools ... dunno ... never heard of it, I'm on Slackware 9.1 
so ... dunno ... Not sure. But like you say, if i could not initalize modules 
the nvidia module should be the least of my worries, plus everything loads in 
2.4.22

on make install i get:

That's the same thing that modprobe nvidia gets. 
I'll check the nv thing out.

One interesting error / warning i get during boot is this (from /var/log/
syslog) :
Jan 22 10:43:08 stormcrow kernel: nvidia: version magic '2.6.1 preempt K7 
gcc-3.2' should be '2.6.1 preempt K7 gcc-3.3'
Jan 22 10:46:15 stormcrow kernel: nvidia: version magic '2.6.1 preempt K7 
gcc-3.2' should be '2.6.1 preempt K7 gcc-3.3'

Not sure what to make of this. I know that 4496 had issues with the gcc 
version i was running a while backed, and i had to hack the installer script 
to ignore that (though i'm sure there is a switch for this stuff ... i was 
over reading at that point).

As for the XFree log ... i don't have that one ...

The 2.6 kernel needs new tools to load the kernel modules, because they have a 
different format (not just a different extension with .ko).  
module-init-tools provides those necessary upgrades, and also aids in 
creating /etc/modprobe.conf, which is used instead of /etc/modules.conf under 
the 2.6 kernels for loading modules on startup.  If you don't have 
module-init-tools, then I'm not surprised you are having problems.  You 
probably need an updated mkinitrd as well if you are using an initrd on 
system startup.

They should be at http://www.kernel.org/pub/linux/kernel/people/rusty/modules/

You probably want to read a document that summarized the changes that happened 
in 2.6, which is where the link above was located.  It is 
http://www.linux.org.uk/~davej/docs/post-halloween-2.6.txt

Not knowing much about Slackware, I couldn't give you much help about where 
the best place to get your tools from might be, except for the source above.

/var/log/XFree86.0.log would be the place.  I don't think there will be 
anything interesting there until you get your module-init-tools installed.

I hope this has helped.

Slackware 9.1 comes with module-init-tools in anticipation of 2.6. did you run 
a full install or select by hand?

My guess is you need to have a "built" kernel tree.  Basically just
build the kernel, install, reboot, then without touching the kernel
tree you built rebuild the nvidia driver.  I hope that makes sense.

Re: Nvidia drivers and 2.6.x kernel

[Bob Gill]

Hi.  I also have an Nvidia Ti4200, running on Fedora Core with the
2.6.2-rc1 kernel.  The easiest way to get the driver installed was to
grab a pre-built no-fuss installer from
http://www.sh.nu/download/nvidia/linux-2.6/ and after you build your new
kernel, boot into it, kill X and make sure it stays dead by modifying
/etc/inittab by changing 
respawn:/etc/X11/prefdm -nodaemon
to
# x:5:respawn:/etc/X11/prefdm -nodaemon
(save) and type init q  ...if X wasn't dead before, it is now.  You
should now be able to install the driver (where ever you put it) by just
running >sh <drivername>
Assuming your XF86Config is still setup to deal with the binary nVidia
driver, when you uncomment the line in the /etc/inittab file and re-run
init q, X should start with an nvidia splash screen.  Please be aware
that there are problems with agpgart on via chipsets (I don't have one,
I'm quoting from the minion page).  And there is a procedure for getting
mesa (and optionally glut) installed alongside the binary nvidia driver
(and a bit more if you want tv with overscan).
