__xe_sa_bo_manager_init(9)

💖 NAME 💖

__xe_sa_bo_manager_init(9) — Create and initialize the suballocator, and yes bestie this is the Kernel API Manual page for it. It's giving set up the suballocator era 💅.

✨ SYNOPSIS ✨

struct xe_sa_manager * __xe_sa_bo_manager_init (struct xe_tile *tile ,
       u32 size , u32 guard , u32 align , u32 flags );

🩷 ARGUMENTS 🩷

• tile — the xe_tile where allocate 🛠️, aka the tile situation where the allocation happens.
• size — number of bytes to allocate, fr fr.
• guard — number of bytes to exclude from suballocations, so we're literally setting that space aside 🚫.
• align — alignment for each suballocated chunk, iconic for keeping things lined up ✨.
• flags — flags for suballocator, the little switches that set the vibe 🎛️.

🦋 DESCRIPTION 🦋

Okay so this function prepares the suballocation manager for suballocations. That's it, that's the whole job — manager gets prepped, suballocations get ready to happen, lowkey main character energy 💅.

🔥 RETURN 🔥

You get a pointer to the xe_sa_manager on success, or an ERR_PTR on failure 😭. So like, check it before you go off, bestie.
