Hi Greg, Currently, the sensors-detect script uses /proc/bus/pci/devices (file) to get a list of the PCI devices on the system. As this file doesn't contain PCI class data, and I need it, I was looking for an alternative. For 2.6 kernels, /sys/bus/pci/devices (directory) looks like the right place to look at. This raises a few questions, which I hope you can answer: 1* /proc/bus/pci/devices doesn't appear to contain PCI domain information. I guess it only lists the devices on domain 0000, and would miss devices on multi-domain machines? 2* Since which kernel version does /sys/bus/pci/devices look like the way it is right now? Did the device IDs always include the PCI domain? If it's stable since 2.6.0, I could use it in sensors-detect. 3* Will /sys/bus/pci/devices go away eventually? Thanks, -- Jean Delvare
