💖 lpfc_sli4_rb_alloc(9) 💖

okay so bestie, welcome to the kernel API manual for lpfc_sli4_rb_alloc — yes that's a lot of letters, no you don't have to say it out loud, we're just gonna vibe through it together 🫶

✨ NAME ✨

lpfc_sli4_rb_alloc — allocate an SLI4 Receive buffer 💅

🌸 SYNOPSIS 🌸

struct hbq_dmabuf * lpfc_sli4_rb_alloc (struct lpfc_hba *phba );

that's it. one argument. we love a low-effort icon 👑

🎀 ARGUMENTS 🎀

  • phba — the HBA you're allocating a receive buffer for, like it's the main character and you're getting it a gift 🎁

🦋 DESCRIPTION 🦋

so what it actually does: it allocates a DMA-mapped receive buffer from the lpfc_hrb_pool PCI pool, and along with it, a non-DMA-mapped container for that buffer. two for the price of one, lowkey iconic ✨

💜 NOTES 💜

ok bestie listen to me very carefully 👀 this one is not interrupt-safe, and it must be called with no locks held. no cap. do not come in here holding a lock, that's not the vibe fr fr 😭

⭐ RETURN ⭐

pointer to HBQ on success — and NULL on failure, which is giving "we tried 💀"
