Description D Bera 2007-10-19 05:51:27 UTC

xf86-video-intel/src/bios_reader/bios_dumper returns 0 size file for some machines. I was told that this is a libpciaccess bug.

pci_device_find_by_slot(0, 0, 2, 0);
returns a dev with dev->rom_size=0.
This is a Dell Inspiron 1100 with 82845 graphics card. Here is the relevant lspci output:

00:00.0 Host bridge: Intel Corporation 82845G/GL[Brookdale-G]/GE/PE DRAM Controller/Host-Hub Interface (rev 03) 

00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE  Chipset Integrated Graphics Device (rev 03)

What is the output of:

cat /sys/bus/pci/devices/0000\:00\:02.0/resource

With that, I can see what pci_device_linux_sysfs_probe did with it to come up 
with that result

Marking as dupe of #19061 which provides more information (like the resource 
file requested)
