Abstract
Provided are a computer program product, system, and method for using system memory to store initialization data for initialization of devices on a link. A link initialization memory area is initialized in a system memory of the first device. A bus address in a bus interface is provided that maps to the link initialization memory area. A first device writes first initialization data to the bus address to cause the first initialization data to be written to the link initialization memory area. A second device writes second initialization data over the bus interface to the bus address to cause the second initialization data to be written to the link initialization memory area. The first device and the second device communicate Input/Output (I/O) requests over the link in response to the writing of the first initialization data and the second initialization data to the link initialization memory area.
