 Posted: Thu Jun 01, 2006 11:00 pm Post subject: Kernel: VIA PT894 not totally recognised [SOLVED] |
 |
|
Hello,
I have a probem with a VIA PT894 Host bridge:
lspci
00:00.0 Host bridge: VIA Technologies, Inc. PT894 Host Bridge
00:00.1 Host bridge: VIA Technologies, Inc. PT894 Host Bridge
00:00.2 Host bridge: VIA Technologies, Inc. PT894 Host Bridge
00:00.3 Host bridge: VIA Technologies, Inc. PT890 Host Bridge
00:00.4 Host bridge: VIA Technologies, Inc. PT894 Host Bridge
lspci -n
00:00.0 0600: 1106:0308
00:00.1 0600: 1106:1308
00:00.2 0600: 1106:2308
00:00.3 0600: 1106:3208
00:00.4 0600: 1106:4308
However
grep 308 /usr/include/linux/pci_ids.h
#define PCI_DEVICE_ID_NVIDIA_QUADRO_FX_2000 0x0308
grep 308 /usr/src/linux-2.6.16-gentoo-r7/include/linux/pci_ids.h
#define PCI_DEVICE_ID_NVIDIA_QUADRO_FX_2000 0x0308
I understand it as: a video card is assigned instead of the VIA Host bridge.
As a result, agpgart finds nothing:
dmesg | grep agp
Linux agpgart interface v0.101 (c) Dave Jones
and I cannot get drm... 
Any comment? Is that a bug?
How can I quickly fix it?
Do I need to rebuild the kernel if I change the pci_ids.h file?

This issue has been fixed in the upcoming kernel 2.6.17. See http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=7dd1d9b85cfb63eebf48fa13d3c5d25a3deb3a25 for the patch in the kernel git.
Here's the patch, with which I can get drm without any problem, for your convenience:

After applying the patch you need to rebuild the via-agpgart module (or your kernel if compiled in). |

By the way, your patch does not cover:
#define PCI_DEVICE_ID_NVIDIA_QUADRO_FX_2000 0x0308
What am I supposed to do with that?

Leave it as it is. It's not a problem to have duplicates for devices in the pci_ids.h file. Each device is identified by the pair VENDOR_ID:DEVICE_ID. The VENDOR_ID is different for NVidia and VIA devices.
PS: Please mark this thread as [SOLVED] once you have your system patched and running

Hello,
Of course but how am I supposed to mark a thread 'SOLVED'. How do I do that? |
