lspci unknown device for HP Nvidia Quadro 4 graphics

[Rauschenberg]

Hi,

after installing my EVO D530 with a HP Nvidia Quadro 4 280 NVS (PCI!!!) the system is running well, but lspci tells me the VA controller is "NVidia Corporation: unknown device (032a)".
I installed the latest Nvidia driver, TwinView is OK, but the problem resists.
XFree86 update didn´t make anything better..

Any ideas?

Thanks
Matthi

If the displays are working ok, then I wouldn't be concerned about this.

If you really are concerned, make sure your version of 'lspci' is the latest release etc. and try again.

Dear Stuart,

thanks for your answer. You are right not to be concerned about it, the problem is a customer is using lspci output for maintenance and installation scripting.
I found out that the output displays the chip ID (0x032a) correctly.
Maybe the chip is not known by the kernel?? How can I list the known hardware??

Thanks

Well that is a good question but it does not have a complete and definitif answer, if you do an advance search on google on this you will find lot of very heated questions and answers on this, but the bootom line is Linux kernel developper try to follow well know "Standard, well define, described and commonly known hardware" there are zillion's of hardware out there probably some new one, since i started this answer ! the linux kernel code reflects and try's to sort this "not so well behave, sometimes very messy competition driven environment".. So it give user's of linux and the kernel tool and tactics to identify chip's,board's, hardware
("So if the chip is identify but the board does not return the right information as to is identity it is probably new, not common, or does not follow know "standard has not been identified or worth an exeption in the kernel code ".

the above is an opinion " a try to explain why it is the best posible answer ".

There are of course Hw compatibily list maintain by RedHat and other distributions,and one should do a search on the web about the hw one is about to buy to see if there are lot of problems with it, a good way is to stick with well tested sometimes older well know chips/board you can also edit/list all the various chips that the kernel config file know about and try to read "decode" all the files modules under the /usr/src/linux to find all the hardware that is know to this particular kernel you are looking at.

You could use thing like lspci "(hint: use the lspci -vvv)" or the /proc/ or the sysreport from redhat to base code on but then you need to treat unknow and exeptions... not so easy in a "dynamic ever changing market 'I nearly say'd battel field'

Sorry hit submit instead of edit on review while in previous reply, I still needed to clear this long answer a littel, Oh but well it say's most of what I wanted.

Hardware support does vary from distribution to disribution. I don't see what distribution of Linux you are using.

As far as I know the best hardware support is in the following distributions.

Fedora
Red Hat
Mandrake
Suse

Thats based on experience and threads here.
