ksz_get_appt..._map_and_reg(9)

💅 ksz_get_appt..._map_and_reg(9) — from the Kernel API Manual, section 9, bestie 🎀

Okay so real talk, this one's a kernel API page, section 9, and the function name is honestly a whole mouthful: ksz_get_apptrust_map_and_reg. Yes the title up top is abbreviated because even the manpage generator was like "girl, that's too long." We move. 💀

✨ NAME ✨

ksz_get_apptrust_map_and_reg — literally just retrieves the apptrust map and the register. That's it. That's the whole gig. 🫶

---

🌸 SYNOPSIS 🌸

void ksz_get_apptrust_map_and_reg (struct ksz_device *dev , const struct
ksz_apptrust_map **map , int *reg , u8 *mask );

Note the void, bestie — nothing comes back as a return value, everything you want gets written through the pointers. Classic. 👑

---

🦋 ARGUMENTS 🦋

• dev — Pointer to the KSZ switch device structure. The main character, honestly — it's the switch we're talking about.
• map — Pointer to the apptrust map to be set. Yeah, "to be set," that's what the page says, don't @ me.
• reg — Pointer to the register address to be set. Same energy.
• mask — Pointer to the mask to be set. The third member of the pointer trio. 💅

fr fr, all three of map, reg and mask are described as "to be set" — that's straight from the source, no cap, I'm not editorializing.

---

⭐ DESCRIPTION ⭐

So what does it actually do? It retrieves the apptrust map and the register address for the apptrust configuration. That's the tea. ☕ It's giving "small helper, big responsibilities." 🧚

Cute lil sign-off: this one lives in ./drivers/net/dsa/microchip, dated October 2026 — so yeah, it's from the future apparently, we stan a forward-thinking manpage. 🦋✨🎀
