💖 hw_event_sas_phy_up(9) 💖

okay so welcome to the Kernel API Manual bestie, section 9, we're literally in the kernel source and it's giving driver internals ✨ this one's about a firmware event handler in the pm8001 SCSI crew, and honestly? iconic behavior.

---

🦋 NAME 🦋

hw_event_sas_phy_up — the firmware literally tells me a SAS phy up event happened. that's it. that's the whole vibe. it's a notification, she's a messenger 🫶

---

🌸 SYNOPSIS 🌸

void hw_event_sas_phy_up (struct pm8001_hba_info *pm8001_ha , void
*piomb );

returns void, meaning she does the work and gives you nothing back — no return value, no crumbs, just vibes 💅

---

🎀 ARGUMENTS 🎀

• pm8001_ha — our hba card information 🃏 like, the whole personality of the host bus adapter, all the info about our card, the main character's lore
• piomb — IO message buffer 📬 the little message that came in, holding the event payload
