SPDMEM(4)                  Kernel Interfaces Manual                  SPDMEM(4)

NAME
     spdmem -- Generic Memory Module Serial Presence Detect

SYNOPSIS
     spdmem* at iic? addr 0x50
     spdmem* at iic? addr 0x51
     spdmem* at iic? addr 0x52
     spdmem* at iic? addr 0x53

DESCRIPTION
     The spdmem driver provides support for generic memory module Serial
     Presence Detect.  During kernel boot it displays module type, and where
     possible, the size and rated speed of the memory module.  Additional
     information such as bank configuration and width is printed if the kernel
     is booted in verbose mode.

     The Serial Presence Detect data for each memory module is also made
     accessible to user mode via sysctl(8).  An entry for each spdmem device
     is created under the hw top-level MIB.

SEE ALSO
     iic(4), intro(4)

HISTORY
     The spdmem driver first appeared in NetBSD 5.0.

AUTHORS
     The spdmem driver was written by Nicolas Joly <njolyATpasteur.fr> with
     additional work by Paul Goyette <paulATwhooppee.com>.
