lpfc_sli4_nvmet_alloc(9)

💅 lpfc_sli4_nvmet_alloc

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a little function from the SCSI lpfc driver and honestly it's giving "small but mighty" energy. Let's get into it 🎀

---

🌸 NAME 🌸

lpfc_sli4_nvmet_alloc — allocates an SLI4 Receive buffer 🫶

🦋 SYNOPSIS 🦋

struct rqb_dmabuf * lpfc_sli4_nvmet_alloc (struct lpfc_hba *phba );

💖 ARGUMENTS 💖

• phba — the HBA you're allocating a receive buffer for, like, that's the whole vibe check right there 👑

⭐ DESCRIPTION ⭐

So what does it actually do? It allocates a DMA-mapped receive buffer straight out of the lpfc_hrb_pool PCI pool — and it also grabs a non-DMA-mapped container to go with it 🧚✨ that's it, that's the whole job, and it does it flawlessly, no cap.

🔥 RETURN 🔥

• pointer to HBQ on success 🎉
• NULL on failure 💀 (sad but honest)
