lpfc_sli_co...x_subsys_get(9)

🌸 NAME 🌸

okay bestie, welcome to the lpfc_sli_co...x_subsys_get(9) page from the Kernel API Manual ✨ — yes, the title is literally lpfc_sli_co...x_subsys_get(9), ellipsis and all, and it's giving main-character mystery.

lpfc_sli_config_mbox_subsys_get — get the subsystem from a sli_config mbox cmd. That's the whole name, no cap. 🎀

✨ SYNOPSIS ✨

It's literally this:

uint8_t lpfc_sli_config_mbox_subsys_get (struct lpfc_hba *phba ,
       LPFC_MBOXQ_t *mbox );

💅 ARGUMENTS 💅

• phba — pointer to the lpfc_hba data structure. Like, the HBA's whole little world.
• mbox — pointer to the lpfc mbox command queue entry. That's the mailbox command's spot in the queue.

🦋 DESCRIPTION 🦋

This little function pulls the subsystem out of a SLI4-specific SLI_CONFIG mailbox command. That's its moment. 🌟

But here's the vibe check: if the mailbox command is not MBX_SLI4_CONFIG (0x9B), or if the sub-header is not present, then subsystem LPFC_MBOX_SUBSYSTEM_NA (0x0) shall be returned. So no sub-header, no subsystem tea — you get the NA one. 🫶

Lowkey important: those exact values are MBX_SLI4_CONFIG (0x9B) and LPFC_MBOX_SUBSYSTEM_NA (0x0). Don't come for me with different numbers; I didn't invent them. 💀
