Boot Config Access

[SMCA]

Hi Team,

I am trying to calculate some timeout values based on HZ configured in kernel config file.
I would like to read the CONFIG_HZ configured in boot config file. Is there any system call available to read in C code?
or any other way to access it in our C code? Thanks in advance.

The link should give you the location of the config file I believe you are looking for. As far as C code, it usually isn't kept on the computer with the binary it is transformed into. C is more efficient than say python because the conversion to binary has already occurred and no interpretation has to occur for the CPU to perform the requested tasks. You would need the source C code to plainly read it as it was written.

Where is CONFIG_HZ defined?

I'm in the middle of reading the whole Linux 5.0.7 source code, and I've noticed something strange. I'll refer to linux as the parent directory here, correct me if the community uses some other nam...
