💅 DESCRIPTION 💅

Okay so the icp driver provides support for the newer (post 1997) ICP-Vortex GDT and Intel Storage RAID controllers. Literally the post-1997 era said “we’re doing RAID now” and this driver said “say less.” 🦋

The ld driver provides access to logical devices (disk arrays) presented by the controller. So that’s your disk-array main character energy. 👑

The icpsp driver provides direct access to other SCSI devices attached to the controller, such as tape or CD-ROM drives. Not me giving you a direct little side door to tape and CD-ROM besties. 🎀

🚨 DIAGNOSTICS 🚨

• pci_mem_find: expected mem type 00000000, found 00000002 — this message may be displayed during autoconfiguration if the controller's memory is mapped below 1MB in physical address space. This can be disabled either through changing a setting in the controller's BIOS utility, or changing the position of a jumper on the board. See your controller's documentation for more information. Ngl, if you see this, it’s giving “check the BIOS utility or the jumper,” so don’t just ignore it, bestie. 💀

🕰️ HISTORY 🕰️

The icp driver first appeared in NetBSD 1.6, and was based on the FreeBSD and OpenBSD drivers of the same name. So she’s got that cross-BSD origin story — lowkey iconic. 🌈

💀 BUGS 💀

ISA & EISA front-ends and a management interface are needed. Fr fr, those are still needed. 🍓

Older PCI boards are not yet supported. Periodt, older PCI boards are not yet supported. 🙈
