[SOLVED] Issue installing a external GPU device

aihaike · 07-11-2011, 07:53 PM

I think the module is already associated to the device.
modindo nvidia gives

Code:

This information is partially taken from /lib/module/`uname -r`/modules.alias
But modprobe nvidia gives me a "No such device" error, dmesg the following

Code:

NVRM: This PCI I/O region assigned to your NVIDIA device is invalid:
NVRM: BAR0 is 0M @ 0x0 (PCI:0000:01:00.0)
NVRM: The system BIOS may have misconfigured your GPU.
nvidia: probe of 0000:01:00.0 failed with error -1
NVRM: The NVIDIA probe routine failed for 1 device(s).
NVRM: None of the NVIDIA graphics adapters were initialized!

Thank you.

I've just realized that I can "remove" (actually switch off) the device and put it back
To remove it, I do

Code:

echo 1 > /sys/bus/pci/devices/0000\:01\:00.0/remove
and
echo 1 > /sys/bus/pci/devices/0000\:01\:00.1/remove

and it does not appear in lspci output anymore.

Then I switch it off.
After that, I start it again.
If I do lspci, it (obviously) does not appear in the list.
I do

Code:

echo 1 > /sys/bus/pci/rescan

And here it is!!
It works 100% of time (of my tests).

When the device gets detected, demesg shows

Code:

That would be awesome if someone can explain to me the meaning of this and if there is a way solve this issue.
Thank you,

Éric.
