修改英特尔功率钳比错误？

Question

按照IntelPower钳指令(https://www.kernel.org/doc/Documentation/thermal/intel_powerclamp.txt)，我尝试使用他们推荐的Konsole：sudo sh -c "echo 15 > /sys/class/thermal/cooling_device80/cur_state "设置比率--这给出了一个错误：sh: 1: cannot create /sys/class/thermal/cooling_device80/cur_state: Directory nonexistent

编辑0:我运行命令并得到：

sarah@ConvergentRefuge:~$ ll /sys/class/thermal/cooling_device* lrwxrwxrwx 1 root root 0 Feb 9 09:01 /sys/class/thermal/cooling_device0 -> ../../devices/virtual/thermal/cooling_device0/ lrwxrwxrwx 1 root root 0 Feb 9 09:01 /sys/class/thermal/cooling_device1 -> ../../devices/virtual/thermal/cooling_device1/ lrwxrwxrwx 1 root root 0 Feb 9 09:01 /sys/class/thermal/cooling_device2 -> ../../devices/virtual/thermal/cooling_device2/ lrwxrwxrwx 1 root root 0 Feb 9 09:01 /sys/class/thermal/cooling_device3 -> ../../devices/virtual/thermal/cooling_device3/ lrwxrwxrwx 1 root root 0 Feb 9 09:01 /sys/class/thermal/cooling_device4 -> ../../devices/virtual/thermal/cooling_device4/ lrwxrwxrwx 1 root root 0 Feb 9 09:01 /sys/class/thermal/cooling_device5 -> ../../devices/virtual/thermal/cooling_device5/ lrwxrwxrwx 1 root root 0 Feb 9 09:01 /sys/class/thermal/cooling_device6 -> ../../devices/virtual/thermal/cooling_device6/ lrwxrwxrwx 1 root root 0 Feb 9 09:01 /sys/class/thermal/cooling_device7 -> ../../devices/virtual/thermal/cooling_device7/ lrwxrwxrwx 1 root root 0 Feb 9 09:01 /sys/class/thermal/cooling_device8 -> ../../devices/virtual/thermal/cooling_device8/ lrwxrwxrwx 1 root root 0 Feb 9 09:01 /sys/class/thermal/cooling_device9 -> ../../devices/virtual/thermal/cooling_device9/

但是当我运行sudo sh -c "echo 15 > /sys/class/thermal/cooling_device0/cur_state"时，我得到了一个I/O错误。

Answer 1

cur_state路径中的一个目录要么不存在，要么有一个中断的符号链接。很有可能是cooling_device80
