FYI - inserting module for NVIDIA 304.131 (possibly 340.xxx) and kernel 4.4.14<


Recently I was doing upgrade from 14.1 to 14.2 and hit the wall of buggy nvidia blob.
The kernel module driver 304.131 build nice for kernel 4.4.14 but couldn't be loaded during boot time.
I have red somewhere on the LQ Slackware forum that if you want to load kernel module you have to patch the kernel or wait to NVIDIA devs do their job.
Since i don't like to mess with smarter than me i would not touch this source code.

Instead of that I've founded patch for driver 304.131. I think that this can be useful for 340 series too.

patch:
Code:
--- a/nv-linux.h
+++ b/nv-linux.h
@@ -256,6 +256,15 @@
 #include <linux/seq_file.h>
 #endif
 
+/*
+ * As of version 304.131, os-agp.c and os-mtrr.c still use deprecated
+ * kernel APIs for mtrr which are no longer exported since 4.3, causing
+ * the module to error out when loaded.
+ */
+#if LINUX_VERSION_CODE >= KERNEL_VERSION(4,3,0)
+#undef CONFIG_MTRR
+#endif
+
 #if !defined(NV_VMWARE) && defined(CONFIG_MTRR)
 #include <asm/mtrr.h>
 #endif
source:
https://devtalk.nvidia.com/default/t...on-kernel-4-4/

For me this solution works like a charm. -> nv43 - GeForce 6600.
Hope this helps.

These may work too:

The 340 version worked for my 9800m gts

Yes indeed.
@willysr
I've looked at yours solution and You patched the kernel. Maybe it is good way to do it, but personally I don't know if other apps or drivers would need that instructions in kernel to run properly.

@RadicalDreamer
You are right.
I'd to modify slackbuild script downloaded from slackbuilds.org through sbopkg's possibility of package customization. I've added patch command accordingly to Slackbook's manual on writing slackbuilds scripts. Pure one resulted dmesg errors about mtrr's during module insertion.

BTW on my machine (AMD Sempron 2600, KT333, agp8), compiling the kernel would took ages.

There is another thread with information here.

Dual core processor running 'make -j3 bzImage' completes in ~12 minutes. You only need to compile the kernel, rather than kernel and modules.

so far, nothing is broken by the patch, so i'm happy with it

I did an upgrade 14.1-> 14.2 slackware system, but there was a nvidia fault. After trying rebuilt kernel using mtrr.pacth, I found fault and module errors on

/var/log/nvidia-installer.log.


Nvidia messages pointed to use steps using beyond make oldconfig

make prepare


I did, but unfortunatelly there was kernel error again.


For now there is another nvidia-kernel installed since 14.1. Do you think it can be causing this installer problem?

Are you using 14.2 release after a upgrade or a fresh install?

FWIW I just did a fresh 14.2 32 bit install with 4.14.4 kernel om an older laptop with a Quadro 570m. I blacklisted nouveau and just used nVidia's 340.96 install script from runlevel 3 and it loads and works perfectly, even on HD videos so far.

you should copy the generic one instead of huge kernel's config

Itīs only a Linuxquestion post mistake. Sorry!

I run this copy correctly during system procedures.



I tried it again and used another nvidia-driver ( 340.88) and my nvidia-installer.log shows:

ERROR: Kernel configuration is invalid
; and
include/generated/autoconf.h or include/config/auto.conf are missing



Disabling kernel driverīs install and reading nvidia.ko

And after trying

make prepare; and
make bzImage

returned cpu-kernel erros
