reset_select_slave(9)

💅 reset_select_slave(9) — like, the whole glow-up

okay so this is a page straight outta the Kernel API Manual, bestie. it's about reset_select_slave, and yes we're gonna get into it. 🎀

---

✨ NAME ✨

reset_select_slave — reset and select a slave, that's the whole vibe, that's the whole job 🫶

---

🌸 SYNOPSIS 🌸

int reset_select_slave (struct w1_slave *sl );

---

🦋 ARGUMENTS 🦋

• sl — the slave to select. that's the one, bestie, that's our main character 👑

---

💖 DESCRIPTION 💖

so what this does is: it resets the bus and then selects the slave by sending a ROM MATCH cmd. simple, iconic, no notes. ✨

now, ngl, there's a whole backstory here: w1_reset_select_slave from w1_io.c could not be used here. why? because it sent a SKIP ROM command if only one device is on the line. and at the beginning of that whole process, sl->master->slave_count is 1 — even if more devices are actually on the line. and that? that causes a collision on the line. 😭💀

so yeah, that's literally why this function exists. iykyk.

---

🔥 CONTEXT 🔥

the w1 master lock must be held. not optional, not a suggestion, hold the lock fr fr 🔒

---

⭐ RETURN ⭐

• 0 if success 🎉
• a negative kernel error code otherwise 🙈
