ibmvmc_send_add_buffer_resp(9)

💖 ibmvmc_send_add_buffer_resp(9) 💖

Okay bestie, welcome to the Kernel API Manual entry for this kernel function. It’s giving kernel-internals realness, and we’re gonna walk through it together 💅✨

---

🌸 NAME 🌸

ibmvmc_send_add_buffer_resp — Add Buffer Response. That’s the whole name vibe, no cap.

---

✨ SYNOPSIS ✨

int ibmvmc_send_add_buffer_resp (struct crq_server_adapter *adapter , u8
       status , u8 hmc_session , u8 hmc_index , u16 buffer_id );

---

🎀 ARGUMENTS 🎀

• adapter — the crq_server_adapter struct. Yep, that exact struct.
• status — the Status field.
• hmc_session — the HMC Session field.
• hmc_index — the HMC Index field.
• buffer_id — the Buffer Id field.

---

🦋 DESCRIPTION 🦋

Okay so this command is sent by the management partition to the hypervisor in response to the Add Buffer message. The Status field indicates the result of the command. Short, sweet, and deeply kernel-coded 🫶

💜 RETURN 💜

• 0 — Success.

That’s the return value listed here, periodt 💅
