[gentoo-user] nvidia and kernel support

[gentoo-user] nvidia and kernel support

[Sean]

Trying to setup my system to support my nvidia vid card.

Per instructions I am supposed to enable agpgart in the kernel, which is 
under device drivers--->
	character devices--->
	--- /dev/agpgart (agp support)

As you can see above my system does not allow anything to be done for 
/dev/agpgart, it just has three lines before it.
How do I enable this in the kernel towards getting my nvidia card working?

Please note: if it makes a difference I am running amd64.

				Thanks

"---" means it's enabled (another part of your kernel wants it built-in)

You need to run glxinfo inside X

Do: emerge nvidia-{kernel,glx}

Don't know why I did not realize that I had to have X started for the 
glxinfo test, brain skip on my part.

Started X and works great. Thanks to all the tips. Very responsive group 
here.

Numbers look impressive on the test, first line reads
70644 frames in 5.0 seconds = 14128.800 FPS

The successor lines average over 14500 FPS. That looks very impressive, 
  seems much higher then I would have expected.

Those numbers are by no means representative. The only thing you can
read from it is ">100 = hardware acceleration works" ;)

well, in Xgl, I have ~5500FPS 
with plain X 2500-3500 FPS 

...

so much about the sccuracy.

compare that to ut2004.
with Xgl 5-6FPS
with X 50-180FPS

you don't set anything else on amd64.

Just agp support.

That is enough.

Rebuild, configure X properly, emerge nvidia-kernel, eselect opengl set 
nvidia, start X.

Is this "Just agp support" something else other then what the handbook 
instructions state about /dev/agpgart (agp support)?
As mentioned above that option is not available to me.

As Mr. Norberto Bensa wrote: "---" means it's enabled (another part of your kernel
wants it built-in)

Additionally the help about this feature reads:

  │ Symbol: AGP [=n]
  │ Prompt: /dev/agpgart (AGP Support)
  │   Defined at drivers/char/agp/Kconfig:1
  │   Depends on: (ALPHA || IA64 || PPC || X86) && !GART_IOMMU
  │   Location:
  │     -> Device Drivers
  │       -> Character devices

  │

I would suppose you have some of the Intel cards under "Device Drivers/Graphics
support" enabled by "YES". My suggestion is that under "Graphics Support" you
disable everything but:

 <*> Support for frame buffer devices
  &#9474; [*]   Enable Video Mode Handling Helpers
  &#9474; [*]   VESA VGA graphics support

Then go back to Character Devices and enable apggart.

link?

and: if you have enabled iommu support, agpsupport is built in the kernel. 
Because both are the same for AMD64.

There is nio good reason to build agpsupport as modul on amd64, so it is ok to 
build it in. Just make a kernel, install the kernel and install nvidia-kernel 
and nvidia-glx.

Actually, if you want to use the nvidia agpgart drivers, agpgart support
should be a module. Depending on your nvidia options, it will be loaded
when the nvidia module is loaded, or nvidia will handle agpgart itself.

>From the README:

X Config Options

Option "NvAGP" "integer"

    Configure AGP support. Integer argument can be one of:
    
        Value             Behavior
        --------------    ---------------------------------------------------
        0                 disable AGP
        1                 use NVIDIA's internal AGP support, if possible
        2                 use AGPGART, if possible
        3                 use any AGP support (try AGPGART, then NVIDIA's
                          AGP)

If agpgart is compiled into the kernel, only 2 will work.

My menuconfig still shows --- for the agp line, so based on my responses 
I still have it built in some where do to another dependency.
Tried playing with some of the options, but still shows ---.
I will look at it more.

I guess nvidia's agp looks better then agpgart?
I have not done anything in the X config o wht you mention above.

nope, it does not.

I don't even know, if nvidia-agp really supports amd64.

Just go with the inkernel agpgart. Nvidia even says, that you only should use 
nvidia-agpgart, if your chipset is not supported by inkernel drivers, but the 
nvidia driver.

Go with inkernel driver. It is the right choice.

yeah, but there is no good reason to use the nvidia agpgart driver ;)
