process_one_..._config_spec(9)

💅 process_one_..._config_spec(9) — Kernel API Manual, bestie edition ✨

Okay so this is the process_one_..._config_spec(9) page from the Kernel API Manual, and we’re about to make kernel config parsing make sense. Slay. 💖

🌸 NAME 🌸

process_one_thread_config_spec — processes one component of a thread parameter configuration string and updates the configuration data structure. Literally that’s the whole assignment. 🫶

✨ SYNOPSIS ✨

int process_one_thread_config_spec (const char *thread_param_type ,
       unsigned int count , struct thread_count_config *config );

🧚 ARGUMENTS 🧚

• thread_param_type — the type of thread specified. (const char * energy)
• count — the thread count requested. (unsigned int btw)
• config — the configuration data structure to update. (struct thread_count_config *)

💅 DESCRIPTION 💅

If the thread count requested is invalid, a message is logged and -EINVAL is returned. If the thread name is unknown, a message is logged, but no error is returned.

That’s the whole tea: invalid count gets the error, unknown name gets the log-only treatment. No cap. 💀

🎀 RETURN 🎀

VDO_SUCCESS or -EINVAL. That’s it, that’s the return-value vibe check. ✨
