they have been replaced by functions in /sys.
The deprecated files (and their replacements) include:
- /proc/acpi/sleep (/sys/power/state)
- /proc/acpi/info (/sys/module/acpi/parameters/acpica_version)
- /proc/acpi/dsdt (/sys/firmware/acpi/tables/DSDT)
- /proc/acpi/fadt (/sys/firmware/acpi/tables/FACP)
- /proc/acpi/debug_layer (/sys/module/acpi/parameters/debug_layer)
- /proc/acpi/debug_level (/sys/module/acpi/parameters/debug_level)
- /proc/acpi/processor/*/power (/sys/devices/system/cpu/*/cpuidle/*)
- /proc/acpi/processor/*/performance (/sys/devices/system/cpu/*/
- cpufreq/*)
/proc/acpi/processor/*/throttling (/sys/class/thermal/
cooling_device*/*)
+ /proc/acpi/video/*/brightness (/sys/class/backlight/)
+ /proc/acpi/thermal_zone/*/* (/sys/class/thermal/)
This option has no effect on /proc/acpi/ files
and functions which do not yet exist in /sys.
Be aware that using this interface can confuse your Embedded
Controller in a way that a normal reboot is not enough. You then

some seconds.
An Embedded Controller typically is available on laptops and reads
sensor values like battery state and temperature.
