💅 qla4_8xxx_check_fw_alive 💅

ok so real talk, this is a page from the Kernel API Manual — yes the Kernel API Manual, section 9, and it's about one single tiny little function in the qla4xxx driver that checks whether the firmware is, like, alive. that's it. that's the whole vibe. she's small but she matters ✨

🌸 NAME 🌸

qla4_8xxx_check_fw_alive — check firmware health 🫶

like literally a vibe check but for firmware. is the firmware thriving or is it Not Doing Great.

---

🎀 SYNOPSIS 🎀

int qla4_8xxx_check_fw_alive (struct scsi_qla_host *ha );

returns an int, takes a struct scsi_qla_host * — classic, iconic, no notes 💅

---

✨ ARGUMENTS ✨

• ha — pointer to the host adapter structure. that's the one. the main character. she's the host adapter and you're handing her over so the function can peek at her 💖

---

Interrupt

no cap, this one runs in interrupt context — so be normal about it, okay? don't go blocking, don't go sleeping, don't do anything unhinged in here 😭
