 Posted: Wed Dec 06, 2006 11:46 pm Post subject: fglrx: Internal AGP is not supported in 2.6 kernel [solved] |
 |
|
On amd64, 2.6.18-gentoo-r3, Xorg 7.1, ati-drivers-8.30.3-r1, nforce3 150 mobo, ATI Radeon 9600:
I no longer have DRI working. From my research, the newer ati-drivers no longer use their own internal AGP, meaning you need to enable it in the kernel. I've done that but still can't get things working.
It seems like the ati-drivers are still trying to use internal AGP. How can I fix this?

I don't get it. According to http://gentoo-wiki.com/Ati, I should set these kernel options:
| Code: | Device Drivers --->
Character Devices --->
<M> /dev/agpgart (AGP Support)
<M> Your_AGP_Chipset_Here
< > Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) |
... but my menuconfig looks very different:
| Code: |
│ │--- /dev/agpgart (AGP Support) │ │
│ │<M> Intel 440LX/BX/GX, I8xx and E7x05 chipset support │ │
│ │< > SiS chipset support │ │
│ │< > VIA chipset support │ │
│ │< > Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) │ │ |

Okay, I now suspect that my problem is that the in-kernel AGP is not working.
It should be working, since on amd64 it's now impossible to not build in-kernel AGP support.
| Code: | eve boot # grep -i AGP config
CONFIG_AGP=y
CONFIG_AGP_AMD64=y
CONFIG_AGP_INTEL=m
# CONFIG_AGP_SIS is not set
# CONFIG_AGP_VIA is not set |
But wheras everyone else seems to get messages in their dmesg output about agpgart starting up like "Linux agpgart interface v0.101 (c) Dave Jones"... I get nothing. And I think this makes the ATI driver try to use its internal one, which isn't suported any more.
How to get kernel AGP working? |

Success!
According to this guy, you need to turn off IOMMU to enable AMD64 AGP.
This thread showed me how.
Everything now seems to be working:
| Code: | $ dmesg | grep -i agp
agpgart: Detected AGP bridge 0
agpgart: Setting up Nforce3 AGP.
agpgart: AGP aperture is 32M @ 0xf0000000
[fglrx] AGP detected, AgpState = 0x1f00421b (hardware caps of chipset)
agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0.
agpgart: Putting AGP V3 device at 0000:00:00.0 into 8x mode
agpgart: Putting AGP V3 device at 0000:02:00.0 into 8x mode
[fglrx] AGP enabled, AgpCommand = 0x1f004312 (selected caps) |
| Code: | $ glxinfo | grep direct
direct rendering: Yes |
| Code: | $ lsmod
Module Size Used by
fglrx 467636 8
