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.
