Abstract: Methods and apparatus related to sharing Serial Peripheral Interface (SPI) flash memory in a multi-node server SoC (System on Chip) platform environment are described. In one embodiment, multi-port non-volatile memory is shared by a plurality of System on Chip (SoC) devices. Each of the plurality of SoC devices comprises controller logic to control access to the multi-port non-volatile memory and/or to translate a host referenced address of a memory access request to a linear address space and a physical address space of the multi-port non-volatile memory. Other embodiments are also disclosed and claimed.

Abstract: Generally, this disclosure provides systems, devices, methods and computer readable media for dynamic configuration and enforcement of access lanes to I/O controllers. The System may include a plurality of Input/Output (I/O) controllers and a plurality of lanes. The system may also include a lane mapping module configured to multiplex at least one of the I/O controllers to at least one of the lanes based on a configuration. The system may further include a first processor configured to detect a change request, the change request to modify the configuration from an existing configuration to a new configuration; and a second processor configured to: verify that the new configuration is valid based on a stock keeping unit (SKU) associated with the system; and, if the verification is successful, store the new configuration in non-volatile memory and reset the system.
