💅 qec — SPARC Quad Ethernet Controller 🦋

okay so this is QEC(4) from the Kernel Interfaces Manual — yes the whole vibe is kernel interfaces, we love a low-level era 💖

✨ NAME ✨

qec — the SPARC Quad Ethernet Controller, aka the little Sbus card that could 🎀

✨ SYNOPSIS ✨

qec* at sbus? slot ? offset ?
qe* at qec?
be* at qec?

like literally that's it, that's the whole config vibe, no cap ✨

✨ DESCRIPTION ✨

okay bestie, so the qec driver is an Sbus controller 🦋 and the whole thing with it is that it can hold either:

  • one be(4) Ethernet controller (Sun part number SUNW,501-2655), or
  • four qe(4) Ethernet controllers (Sun part number SUNW,501-2062)

four. whole. ethernet. controllers. one card. the way that's iconic?? 👑

and like, this driver — same as other busses — is not directly available to users. you can't just poke at it, it's not that kind of party 🙈. in essence it is a buffering DMA controller 💫 that's the whole job, that's what it does, periodt.

✨ SEE ALSO ✨

go read those too, iykyk ✨

✨ HISTORY ✨

support for the qec first appeared in NetBSD 1.4 🔥 like okay vintage legend behavior, we stan a long-running queen 👑

and that's the whole page, bestie 🫶 credit where it's due: this one's from Debian, dated March 31, 2004 💜 mwah, slay, go forth and configure your Sbus 💅✨
