I need to retrieve the PCI slot information from ACPI tables using _SUN object. That is why I want access the ACPI tables. After going through the ACPI specs what I found is, this _SUN object will be present in DSDT tables for each device. But when I went and see the ACPI tables in /proc/acpi/dsdt I haven't find any _SUN present in that. So I want what is that mean if _SUN entry is not present in it? When this _SUN object will be present in DSDT? Or Is there any thing wrong in my Assumption that _SUN will be present in DSDT? Or Is my ACPI BIOS don't have _SUN method implemented, that's why it is not displaying in DSDT tables? Thanks, Dhanya -- Kernelnewbies: Help each other learn about the Linux kernel.
