You have access to >all ACPI tables if you wish to parse it yourself in /proc/acpi, right? I have seen the DSDT tables in ACPI (through iasl disassembler) in my machine. But there is no _SUN object entry present in that. Do you have any idea, in which conditions this _SUN object entry will be present in ACPI DSDT tables? Or Is there any issue with ACPI BIOS of my machine if _SUN object is not present in DSDT table? Or Will _SUN object be present in only PCI Hot pluggable machines?
