Description Giulio Sichel 2005-12-02 20:14:25 UTC

Xorg doesn't scan all PCI buses, but just 0000, avoiding the detection of my PCI
graphic card (Voodoo Banshee), located on 0001.
I'm running kernel version 2.6.14.3 sparc64:

Mater:~# uname -a
Linux Mater 2.6.14.3 #1 Sat Nov 26 11:14:34 CET 2005 sparc64 GNU/Linux

and all PCI devices are detected:

The other graphic card is perfectly working (Elite 3D with sunffb driver). I'd
like to use the Banshee as secondary framebuffer, but
this is what Xorg log file reports:

It seems that the scanpci module isn't unable to manage multi-domain PCI:

you might try this patch:

Comment 2 DEMAINE Benoit-Pierre 2006-02-16 11:45:38 UTC

AS4100 = Alpha Server 4100, two PCI bus, same problem:

Xorg can list any hardware on the low chain, including sound and SCSI, but
nothing on higher chain: nor NICs not vga ...

lspci still confirms cards are ok in slots, and other cards of the high chain
works ok.

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.

This should be resolved thanks to pciaccess.  If not, please reopen.

pciaccess support is in X11R7.4 / xserver-1.5, which is in Release Candidate
phase now, and should be released soon.
