✨ initialize_thread_config(9) ✨

🎀 NAME 🎀

initialize_thread_config — Initialize the thread mapping. Yes bestie, this is the Kernel API Manual page for it, and it’s lowkey all about getting that thread config set up. 🫶

💅 SYNOPSIS 💅

int initialize_thread_config (struct thread_count_config counts , struct thread_config *config );

🫶 ARGUMENTS 🫶

• counts — the number and types of threads to create. Like, the whole guest list for the thread party.
• config — the thread_config to initialize. This is the one getting its glow-up.

🌈 DESCRIPTION 🌈

okay so here’s the vibe check, bestie: if the logical, physical, and hash zone counts are all 0, then a single thread will be shared by all three of those zones plus the packer and recovery journal. One thread carrying the whole group chat — iconic.

Otherwise? There must be at least one of each type, and each type will have its own thread, as will the packer and recovery journal. No sharing, periodt.

⭐ RETURN ⭐

VDO_SUCCESS or an error. That’s the whole return situation — success or an error, fr fr.
