📦 version 7.3.1, in nixpkgs unstable

💅 lpfc_sli4_repost_io_sgl_list(9) — NAME 🎀

okay so bestie, welcome to the Kernel API Manual ✨ and buckle up, because today's main character is the function lpfc_sli4_repost_io_sgl_list — and its whole job is: Repost all the allocated nvme buffer sgls. that's it. that's the vibe. 🦋

(also yes, the page title is truncated with ... in it. lpfc_sli4_re..._io_sgl_list(9). it's giving "my name didn't fit in the header" energy and honestly? iconic. 💀)

✨ SYNOPSIS ✨

int lpfc_sli4_repost_io_sgl_list (struct lpfc_hba *phba );

that's the whole signature. clean. minimal. ate. 💅

🌸 ARGUMENTS 🌸

  • phba — pointer to lpfc hba data structure. that's the one (1) thing you gotta hand it, and it's basically the whole adapter's personality in a struct. 🫶

💖 DESCRIPTION 💖

okay so here's the lore. 🌈

This routine walks the list of nvme buffers that have been allocated and repost them to the port by using SGL block post. so like, it's doing a little stroll through the buffer list and yeeting them back out to the port, SGL-block-post style. 🔥

and why do we care? because this is needed after a pci_function_reset/warm_start or start. that fresh-start moment. the glow-up moment. ✨

now, the lpfc_hba_down_post_s4 routine is responsible for moving all nvme buffers on the lpfc_abts_nvme_sgl_list to the lpfc_io_buf_list. so that's a whole other function doing the moving — not this one, don't @ me. 💅

and here's the part where we gotta be serious for a sec: if the repost fails, reject all nvme buffers. every single one. no cap, no half measures, it's all or nothing. 😭

🦋 RETURN 🦋

  • 0 = success 🎉
  • non-zero = failure 💀

👑 SEE ALSO 👑

okay the extended fam is HUGE — like, this function knows everybody. all of these live in the kernel file ./drivers/scsi/lpfc/lpfc_sli.c, and here they all are, no cap, nobody left out:

like I said. everybody. iykyk 🧚

and that's the whole page bestie, you ate that 🫶 mwah 💋
