✨ NSCLPCSIO(4) 💅 — National Semiconductor PC87366 LPC Super I/O 🎀

okay bestie, welcome to the NSCLPCSIO(4) page from the Kernel Interfaces Manual — yes, that manual name is folded in right here so we don't have to copy the whole header line like a boring person ✨

🌸 NAME 🌸

nsclpcsio — National Semiconductor PC87366 LPC Super I/O. that's the whole name vibe, no cap 💖

🌈 SYNOPSIS 🌈

nsclpcsio* at isa?
gpio* at nsclpcsio?

🦋 DESCRIPTION 🦋

so the nsclpcsio driver is literally here to provide support for the National Semiconductor PC87366 LPC Super I/O 🫶

this Super I/O incorporates several logical devices, and the following ones are supported: GPIO, VLM, and TMS. periodt 💅

the GPIO logical device provides 29 I/O pins which can be accessed through the gpio(4) framework. the gpioctl(8) program allows easy manipulation of the pins from userland — yes bestie, easy userland pin manipulation, we love to see it 🎀

the VLM and TMS logical devices provides hardware monitoring capabilities to be used with the envsys(4) API. and the following 17 monitoring sensors are available, okay? count them, i'll wait 👑

  • TSENS1 — units: uK — typical use: Remote diode
  • TSENS2 — units: uK — typical use: Remote diode
  • TNSC — units: uK — typical use: Local diode
  • VSENS0 — units: uV DC — typical use: External source
  • VSENS1 — units: uV DC — typical use: External source
  • VSENS2 — units: uV DC — typical use: External source
  • VSENS3 — units: uV DC — typical use: External source
  • VSENS4 — units: uV DC — typical use: External source
  • VSENS5 — units: uV DC — typical use: External source
  • VSENS6 — units: uV DC — typical use: External source
  • VSB — units: uV DC — typical use: VSB
  • VDD — units: uV DC — typical use: VDD
  • VBAT — units: uV DC — typical use: VBAT
  • AVDD — units: uV DC — typical use: AVDD
  • TS1 — units: uV DC — typical use: Thermistor
  • TS2 — units: uV DC — typical use: Thermistor
  • TS3 — units: uV DC — typical use: Thermistor

like, 17 sensors just sitting there being iconic 📊✨

🎀 HISTORY 🎀

the nsclpcsio device appeared in NetBSD 2.0. a little retro, a little classic, we respect it 💖

💀 BUGS 💀

🚨 bug alert, bestie 🚨 The chip decodes address ranges which are not obvious and cannot be controlled by the kernel configuration file (must be set up by the BIOS).

so yeah, not an obvious-address-ranges situation, and the kernel configuration file cannot control them — BIOS has to set it up. no cap, that's the caveat 😭

xoxo 💖 — this page came from Debian, dated November 9, 2007, and the manual name is still NSCLPCSIO(4) ✨ bye bestie! 🦋
