🎀 NAME 🎀

okay so bestie, this is sdtemp(4) from the Kernel Interfaces Manual, and it's the page for sdtemp — JEDEC JC-42.4 compatible memory module temperature sensors. 💖

✨ SYNOPSIS ✨

here's the config vibe, fr fr:

💖 DESCRIPTION 💖

The sdtemp driver holds it down for the Microchip Technology MCP9805/98242 and other chips that conform to JEDEC Standard 21-C section 4.7. Memory module temperature sensors are optional on DDR2 and newer DIMMs — like, not every DIMM is gonna have one, and that's totally fine. 🦋

The way this works: the sensors this driver provides — including the on-chip thresholds for the Alarm Window and Critical level — are accessed through the envsys(4) API. iconic behavior, honestly ✨

The sdtemp supports temperature ranges from -256 to +255 degrees C. yes, literally those numbers 😭🔥

Chips supported by the sdtemp driver include TSE2004av compliant devices and:

  • Analog Devices ADT7408
  • Atmel AT30TS00 and AT30TSE004
  • On semiconductor (Catalyst) CAT34TS02, CAT34TS02C, CAT34TS04 and CAT6095
  • Giantec Semiconductor GT30TS00 and GT34TS02
  • Integrated Deviced Technology TSE2002B3, TSE2002GB2, TSE2004GB2, TS3000B3, TS3000GB0, TS3000GB2, and TS30001GB2
  • Maxim MAX6604
  • Microchip Technology EMC1501, MCP9804, MCP9805, MCP9843, MCP98242, MCP98243, and MCP98244
  • NXP Semiconductors SE97 and SE98
  • STmicroelectronics STTS424, STTS424E, STTS2002, STTS2004, and STTS3000

🕰️ HISTORY 🕰️

The sdtemp device appeared in NetBSD 6.0. periodt 💅

💀 BUGS 💀

⚠️ Interrupt support is unimplemented. like… it is not implemented. at all. 😭

and that's the tea 🫶 this page comes from Debian, dated February 22, 2018, and the manual page name is SDTEMP(4). bye bestie, go stay cool 🌈💜
