First, the name used in procfs doesn't make sense. It just uses the arbitrary stings exported by BIOS. Some of them is meaningless, and even there may be duplicate names. The only benefit is that we can easily figure out which device in the ACPI namespace this interface is for. Second, /sys/class/thermal/thermal_zoneX/device is the symbol link to the real device node, and there is a sysfs I/F named "path" which can be used for the same purpose (find corresponding devices in ACPI namespace) so it's okay that the ACPI thermal zones in /sys/class/thermal doesn't have a name. > Would it be possible to add > it there?

Do you mean making use of "temp[1-*]_label"? As we already know the BIOS name (procfs name) of an ACPI thermal sysfs class device, we can export the name of thermal sysfs class device in "temp[1-*]_label", something like "thermal_zoneX". what do you think? thanks, rui -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
