2.6.11-rc2 incompatible with current nvidia driver

I get the following errors during compile time:

I got the same errors too
I'm using a Debian sid with official packages
I can build nvidia modules with rc1 and all previous kernels. So this problem is specific to 2.6.11-rc2. You can check this build log above.

[zyphr]

From what I can see, it started with Ingo's changes in 2.6.11-rc1-bk9
2.6.11-rc1-bk8 still works ok for me with debian sarge.

[chunkey]

hmm, I made a quick & dirty hack for my SID.

BUT USE IT AT YOUR OWN RISK... (I don't have any AGP-Card anymore)
I can only guarantee, a more or less clean compile...

so either "#undef AGPGART" in os-agp.c (after the last #include"
(don't forget to kick out all kernel agpgart modules, so nvidia uses it own NvAGP)

(I've also made a patch... but it would be PCI-E only, since I haven't test it...)

[zander]

The attached patches (used in combination with the Linux 2.6.10 patches posted here: http://www.nvnews.net/vbulletin/show...49&postcount=1) address this incompatibility; to enable the driver for use with Linux 2.6.11-rc2 and AGPGART, follow the instructions in the post referred to above and additionally apply the patches attached to this post. Disabling AGPGART should also eliminate the build failure, but since NvAGP may not work due to a known problem with Linux 2.6.11 pre-release kernels, operation may be limited to PCI mode.

thanks, works fine!

thanks zander, it's all working ok now =)

No, the patches install fine, but restarting the x server gives a nice black screen (and nothing else). I applied the patches to 6629 (NVIDIA_kernel-1.0-6629-1189413.diff.txt and NVIDIA_kernel-1.0-6629-1201042.diff.txt), and that went ok. I compiled the new kernel and rebooted the computer into the new kernel. I then killed the x server and tried installing the new driver. It failed (complaining about AGP). I then pulled the AGP support out of my build script (commented out the following):
# CONFIG_AGP=m
# CONFIG_AGP_ALI=m
# CONFIG_AGP_ATI is not set
# CONFIG_AGP_AMD=m
# CONFIG_AGP_AMD64 is not set
# CONFIG_AGP_INTEL=m
# CONFIG_AGP_INTEL_MCH is not set
# CONFIG_AGP_NVIDIA=m
# CONFIG_AGP_SIS=m
# CONFIG_AGP_SWORKS=m
# CONFIG_AGP_VIA=m
# CONFIG_AGP_EFFICEON is not set

And I built the kernel again. The build went fine. I rebooted into the new kernel, and killed the x server (from trying to start, basically comment out
#x:5:respawn:/etc/X11/prefdm -nodaemon
in /etc/inittab and run init q), then ran the patched nvidia installer again. This time, it installed without any AGP messages (or actually any error messages of any kind), and silently installed. I then uncommented out the x line in /etc/inittab and ran init q. Where I would normally expect the nvidia splash screen (or sometimes it disappears really fast, and I only get the graphical login prompt), I only got a black screen. No video. I only applied the two patches, do I need to apply more? /proc/driver/nvidia/cards shows:
Model: GeForce4 Ti 4200
IRQ: 10
Video BIOS: 04.25.00.30.00
Card Type: AGP
(When I'm running 2.6.10-bk14 with the stock 6629 driver).

Thanks,...

@snaboofypop: there is a known problem with the NvAGP driver included in current NVIDIA driver releases and 2.6.11 pre-release kernels; on these kernels, your options (until the NvAGP problem has been resolved) are: a) AGP with AGPGART (i.e. with Option "NvAGP" "3" (the default) or with Option "NvAGP" "2") and b) no AGP (i.e. PCI mode).

Works here with the patches and NvAGP 3 option

I did exactly what you guys described, and also got the black screen (and also couldn't get the Nvidia AGP to work). So, I tried AGPGART, and it seems to work.

However, the kernel /proc interface says I have no AGP:

$ cat /proc/driver/nvidia/agp/card 
Fast Writes: 	 Supported
SBA: 		 Supported
AGP Rates: 	 8x 4x 
Registers: 	 0x1f000e1b:0x00000000

But the X log says it would use AGPGART:

(...)
(**) NVIDIA(0): Option "NvAGP" "2"
(**) NVIDIA(0): Option "NoRenderAccel" "off"
(**) NVIDIA(0): Option "CursorShadow" "true"
(**) NVIDIA(0): Option "NoRenderExtension" "off"
(**) NVIDIA(0): Enabling experimental RENDER acceleration
(**) NVIDIA(0): Enabling cursor shadow
(**) NVIDIA(0): Use of AGPGART requested
(...)

And there is no mention of AGP anymore in the log. Does the /proc interface only work with NvAGP (and in this case I'm actually using AGP), or did AGPGART somehow failed?

Need more logs/config files? (Doesn't seem to me like that would help)

[greenghost]

Ops... Sorry about the noise. It is indeed disabled:

$cat /proc/driver/nvidia/agp/status 
Status: 	 Disabled

AGP initialization failed, please check the ouput  
of the 'dmesg' command and/or your system log file 
for additional information on this problem.
