ocxl_context_alloc(9)

✨ ocxl_context_alloc(9) ✨

okay so bestie, welcome to the Kernel API Manual page for ocxl_context_alloc(9) — yes that's the whole header, yes we're doing this 💅

---

🌸 NAME 🌸

ocxl_context_alloc — allocate an OpenCAPI context, that's literally the whole vibe 🦋

---

✨ SYNOPSIS ✨

int ocxl_context_alloc (struct ocxl_context **context , struct ocxl_afu
*afu , struct address_space *mapping );

like, it returns an int, periodt 🔥

---

💖 ARGUMENTS 💖

• context — the OpenCAPI context you're allocating 🎀 ngl this one's important: it must be freed with ocxl_context_free or the vibe check fails 😭 don't leave it hanging, bestie.
• afu — the AFU this context belongs to 💫 like, whose context is it anyway, iykyk.
• mapping — the mapping that gets unmapped when the context is closed 🧚 and guess what, it may be NULL — no cap, that's allowed 🙈
