Just want to point out to all of you guys that in the changelog for kernel 2.6.16-rc5 there is this:
| Code: | commit 60b08c67220cf6faef7410ac6adba23a8a743bf7
Author: Jon Mason <jdmason@us.ibm.com>
Date: Sun Feb 26 04:18:22 2006 +0100
[PATCH] x86_64: no_iommu removal in pci-gart.c
In previous versions of pci-gart.c, no_iommu was used to determine if IOMMU was
disabled in the GART DMA mapping functions. This changed in 2.6.16 and now
gart_xxx() functions are only called if gart is enabled. Therefore, uses of
no_iommu in the GART code are no longer necessary and can be removed.
Also, it removes double deceleration of no_iommu and force_iommu in pci.h and
proto.h, by removing the deceleration in pci.h.
Lastly, end_pfn off by one error.
Tested (along with patch 1/2) on dual opteron with gart enabled, iommu=soft,
and iommu=off.

Even though it appears as though that change was actually in rc4.
fglrx for x86_64 needs the no_iommu symbol to work. So (if it's actually in the binary module), we need to poke ATI with a sharp stick... if it's in the wrappers, we might be able to patch it, else we're going to have to reverse the patch on the kernel ... until then, no more acceleration on newer kernels...
I just submitted a ticket to ATI support... |

Thanks for the heads up!

It's already a problem with 2.6.16-rc2 and 2.6.16-rc3 (nitro1) for me.
2.6.16-rc2
| #modprobe fglrx wrote: | | FATAL: Error inserting fglrx (/lib/modules/2.6.16-rc2-nitro1/video/fglrx.ko): Unknown symbol in module, or unknown parameter (see dmesg) |
| #dmesg tail wrote: |

fglrx: Unknown symbol inter_module_get_request
fglrx: Unknown symbol inter_module_put
fglrx: Unknown symbol no_iommu
fglrx: Unknown symbol inter_module_register |
2.6.16-rc3
| #modprobe fglrx wrote: | | FATAL: Error inserting fglrx (/lib/modules/2.6.16-rc3-nitro1/video/fglrx.ko): Unknown symbol in module, or unknown parameter (see dmesg) |
| #dmesg tail wrote: |

For rc3 I changed the kernel Makefile:
from
| Quote: | | obj-$(CONFIG_OBSOLETE_INTERMODULE) += intermodule.o |
to
| Quote: | | obj-y += intermodule.o |
Still the iommu problem is there. Switching over to nvidia feels very tempting at the moment.

| New ATI driver out. Waiting for it to make it into portage (or for my new nvidia powered notebook to get here, whichever comes first) and then I'll test to see if they listened to my bug report. |
