💅 SIOP(4) — Symbios Logic/NCR 53c8xx SCSI driver 💅

okay bestie, welcome to the Kernel Interfaces Manual, section 4 — this is SIOP(4), and she's here to explain the Symbios Logic/NCR 53c8xx SCSI driver. no cap, she's iconic for a very specific set of controller chips. 💖

🎀 NAME 🎀

siop — Symbios Logic/NCR 53c8xx SCSI driver

🌸 SYNOPSIS 🌸

hppa

siop* at mainbus? irq 3
siop* at phatomas? irq 3

PCI

siop* at pci? dev ? function ?

options SIOP_SYMLED
scsibus* at siop?

✨ DESCRIPTION ✨

The siop driver provides support for the Symbios Logic/NCR 53x8xx series of SCSI controller chips. the lineup is giving very specific vintage tech energy:

  • 53c810, 53c810a and 53c815 (Fast SCSI)
  • 53c820, 53c825 and 53c825a (Fast-Wide SCSI)
  • 53c860 (Ultra SCSI)
  • 53c875 and 53c875j (Ultra-Wide SCSI)
  • 53c876 (Dual Ultra-Wide SCSI)
  • 53c885 (Ultra-Wide SCSI and Ethernet)
  • 53c895 (Ultra2-Wide SCSI)
  • 53c896 (PCI 64bit, dual Ultra2-Wide SCSI)
  • 53c1010-33 (PCI 64bit, dual Ultra160 SCSI)
  • 53c1510d (PCI 64bit, dual Ultra2-wide SCSI)

okay so the SIOP_SYMLED option causes the driver to report SCSI activity on the GPIO pin 1, which is connected to the activity LED on some adapters. at this time only the 53c895 based Symbios and Tekram adapters are known to require this. 💡

and bestie, if both siop and the esiop(4) drivers are compiled, esiop(4) will take precedence for controllers it supports. so esiop gets main character energy when it can handle the controller. periodt. 👑

🌈 HISTORY 🌈

the siop driver first appeared in NetBSD 1.5. vintage slay. 🕰️

🫶 AUTHORS 🫶

the siop driver was written by Manuel Bouyer ⟨Manuel.Bouyer@lip6.fr⟩ for NetBSD. 💌

⚠️ BUGS ⚠️

real talk: siop supports the 53c1010-33 in Ultra2-wide mode only. for Ultra160 support, use esiop(4). no cap, that's the limitation. 💀

💌 that's the tea, bestie — this page is from Debian, dated April 5, 2008, and it's SIOP(4). stay slay and read your manpages. 🎀
