#+TITLE: Clear Kernel Build Error? Fix It

#+DESCRIPTION: arch/x86/kernel/cpu/intel_epb.c:171:2: error: call to undeclared function 'sched _set_itmt_power_ratio'
|
||
|
|
|
||
|
|
when I compile clear kernel with LLVM enabled, I got this error:
|
||
|
|
#+BEGIN_SRC text

||
|
|
arch/x86/kernel/cpu/intel_epb.c:172:2: error: call to undeclared function 'sched_set_itmt_power_ratio';
|
||
|
|
ISO C99 and later do not support implicit function declarations [-Werror,-Wimplicit-function-declaration]
|
||
|
|
sched_set_itmt_power_ratio(256 - val * 2, cpu);

it's obvious that the =sched_set_itmt_power_ratio= function is undeclared
|
||
|
|
so I added the following and it is able to compile :)
