lpfc_sli4_init_rpi_hdrs(9)

💖 lpfc_sli4_init_rpi_hdrs(9) — Kernel API Manual, but make it cute 💖

okay bestie, welcome to the manual page for lpfc_sli4_init_rpi_hdrs(9). This is the Kernel API Manual energy we deserve. 🎀

---

✨ NAME ✨

lpfc_sli4_init_rpi_hdrs — Post the rpi header memory region to the port. Periodt. 💅

---

🦋 SYNOPSIS 🦋

int lpfc_sli4_init_rpi_hdrs (struct lpfc_hba *phba );

---

🌸 ARGUMENTS 🌸

• phba — pointer to lpfc hba data structure. That's the whole argument squad, no cap.

---

💜 DESCRIPTION 💜

okay so this routine is invoked to post rpi header templates to the port for those SLI4 ports that do not support extents. It literally posts a PAGE_SIZE memory region to the port to hold up to PAGE_SIZE modulo 64 rpi context headers. Iconic memory-region behavior, honestly. ✨

This is an initialization routine and should be called only when interrupts are disabled.

bestie, pay attention to that interrupt bit: initialization routine, interrupts disabled. That's the vibe check. 🫶

Return codes: 0 — successful; -ERROR — otherwise.
