tb_drom_read(9)

💜 tb_drom_read(9) — from the Kernel API Manual, bestie

okay so first of all, hi, welcome to the function page for tb_drom_read. This is a kernel API manual entry, and honestly it's giving "small function, big responsibility" energy, so let's get into it 🫶

---

✨ NAME ✨

tb_drom_read — Copy DROM to sw->drom and parse it 🌸

✨ SYNOPSIS ✨

int tb_drom_read (struct tb_switch *sw );

✨ ARGUMENTS ✨

• sw — the router whose DROM we're gonna read and parse, like that's literally the whole vibe of this parameter 💅

✨ DESCRIPTION ✨

So here's the tea ☕: this function reads the router DROM, and if that goes well (no cap, "if successful" is doing a lot of heavy lifting there), it parses the entries and populates the fields in sw accordingly. Basically it fills in the blanks on your switch struct, iconic behaviour honestly ✨

And the best part? It can be called for any router generation 👑 Like, no generational gatekeeping here, every router era is welcome at this function's table 💖

✨ RETURN ✨

• 0 on success 🎉 slay
• a negative errno otherwise 😭 not slay, but at least it tells you what went wrong

✨ SEE ALSO ✨

• Kernel file ./drivers/thunderbolt/eeprom.c
• tb_drom_read_uid_only(9) — the lite version, iykyk 🦋

ngl, if you're poking at DROM parsing at all, you're lowkey doing main character kernel work. obsess. 💀✨
