lpfc_els_unsol_event(9)

💫 NAME 💫

lpfc_els_unsol_event — bestie, this is the one that processes an unsolicited event from an els sli ring ✨

So yeah, that's the whole vibe: unsolicited event comes in from an ELS SLI ring, and this function is the main character who handles it. 🎀

🌸 SYNOPSIS 🌸

void lpfc_els_unsol_event (struct lpfc_hba *phba , struct lpfc_sli_ring
*pring , struct lpfc_iocbq *elsiocb );

No cap, it takes three pointers and returns void — it's giving "I do the work, I don't bring anything back." 💅

🦋 ARGUMENTS 🦋

• phba — pointer to lpfc hba data structure. Like, the whole adapter's info lives here, so of course we need it. 🫶
• pring — pointer to a SLI ring. This is the ring in question, the one the event rolled up on.
• elsiocb — pointer to lpfc els iocb data structure. The iocb bestie in question, basically. 💜

🔥 DESCRIPTION 🔥

Okay so here's what's actually happening. This routine is used to process an unsolicited event received from a SLI (Service Level Interface) ring. 👑

The actual processing of the data buffer associated with the unsolicited event is done by invoking the routine lpfc_els_unsol_buffer — and the way that works is, the iocb buffer gets properly set up first, from the SLI ring on which the unsolicited event was received, and then lpfc_els_unsol_buffer gets called. So it's giving setup-then-handoff, and honestly? Obsessed. The setup is literally the moment, iykyk, because lpfc_els_unsol_buffer only gets to slay once the iocb buffer is ready. 💖

Ngl the order matters here: properly set up the iocb buffer from the SLI ring the unsolicited event came in on, and only then invoke lpfc_els_unsol_buffer. That's the whole pipeline, periodt.
