💖 lpfc_sli_pci_mem_setup(9) 💖

okay so bestie, we're in the Kernel API Manual today and this page is all about lpfc_sli_pci_mem_setup — literally the setup girlie for SLI3 HBA PCI memory space. yeah. we're doing driver-level memory plumbing and we're gonna be normal about it 💅

---

✨ NAME ✨

lpfc_sli_pci_mem_setup — Setup SLI3 HBA PCI memory space.

🎀 SYNOPSIS 🎀

int lpfc_sli_pci_mem_setup (struct lpfc_hba *phba );

🦋 ARGUMENTS 🦋

• phba — pointer to lpfc hba data structure. that's it, that's the whole arg list, she's lowkey a one-argument icon 👑

🌸 DESCRIPTION 🌸

okay so here's the vibe: this routine is invoked to set up the PCI device memory space for a device with the SLI-3 interface spec. that's it. that's her job. she sets up the memory space, she nails it, she leaves ✨

Return codes: 0 - successful, other values - error. no cap, that's the whole contract 😭 so like… check your return value, bestie, please.

fr fr check the return. "other values" is doing a lot of heavy lifting there and she is NOT going to tell you which one you got 🙈

ok that's the whole page bestie, she's short and she's sweet and she's from the source directory ./drivers/scsi/lpfc, dated October 2026, and the version is literally just this same page name again — lpfc_sli_pci_mem_setup(9). slay, go set up some PCI memory 🧚💜✨
