veeprom

The veeprom utility displays the Memory Array hardware information such as

the main board serial number, MAC address of the management interface, and

so on.

Syntax

veeprom [ <device_index> ]

Unaligned host buf

reads

The total I/O read requests from a Memory

Array, but only incremented when an

unaligned host address required special

buffer byte copying to service the DMA

request.

Unaligned host buf

writes

The total I/O write requests to a Memory

Array, but only incremented when an

unaligned host address required special

buffer byte copying to service the DMA

request.

Requested DMA reads

Incremented for each read DMA descriptor

added to the descriptor ring.

A single I/O may result in multiple DMA

descriptors to complete a single I/O request.

Requested DMA writes

Incremented for each write DMA descriptor

added to the descriptor ring. Note that a

single I/O may result in multiple DMA

descriptors to complete a single I/O request.

Flash partial page

reads

Incremented when a DMA descriptor for

read is less than a flash page (4kB) in size. On

a DRAM-based system, this will always be 0.

Flash partial page

writes

Incremented when a DMA descriptor for

write is less than a flash page (4kB) in size

which leads to a hardware Read-Modify-Write

operation.
