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 Pres- ence Detect. During kernel boot it displays module type, and where pos- sible, the size and rated speed of the memory module. Additional informa- tion 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.
