hiii bestie, welcome to the Kernel API Manual! today’s main character is pm80xx_hw_event_ack_req(9) 🎀

For PM8001, some events need to acknowledge to FW — that’s literally the whole vibe here. 💅

🦋 SYNOPSIS 🦋

okay so here’s the exact signature, no cap:

void pm80xx_hw_event_ack_req (struct pm8001_hba_info *pm8001_ha , u32
       Qnum , u32 SEA , u32 port_id , u32 phyId , u32 param0 , u32 param1 );

🎀 ARGUMENTS 🎀

• pm8001_ha — our hba card information 👑
• Qnum — the outbound queue message number.
• SEA — source of event to ack.
• port_id — port id.
• phyId — phy id.
• param0 — parameter 0.
• param1 — parameter 1.
