🌸 NAME 🌸

qla_no_op_mb — this MB (mailbox, not the texting kind, tho same energy 💅) is used to check if the FW is still alive and able to generate an interrupt. otherwise, a timeout will trigger an FW dump + reset. yes bestie, it's giving "are you ignoring me or are you actually dead" 😭

---

🎀 SYNOPSIS 🎀

void qla_no_op_mb (struct scsi_qla_host *vha );

that's it. that's the whole signature. no extra args, no drama, just vibes. ✨

🦋 ARGUMENTS 🦋

• vha — host adapter pointer. that's your whole host adapter, the main character 👑

• qla2x00_set_serdes_params(9) — another one, go check it out 🌈

ngl the whole point of this MB is lowkey serious: if the FW doesn't answer and fire an interrupt, a timeout kicks in and you get an FW dump + reset. so like… it's a wellness check that ends in a whole reset. no pressure 🫶
