The present disclosure relates to utilizing a buffer management system to efficiently manage and deallocate memory buffers utilized by multiple processing roles on computer hardware devices. For example, the buffer management system utilizes distributed decentralized memory buffer monitoring in connection with augmented buffer pointers to deallocate memory buffers accurately and efficiently. In this manner, the buffer management system provides an efficient approach for multiple processing roles to consume source data stored in a memory buffer and to deallocate the buffer only after all roles have finished using it.

Methods, systems, and computer storage media for providing a Shell PCIe Bridge (SPB) and shared-link-interface services that support a shared common PCIe physical link between SPB clients in a PCIe system. In operation, shared-link-interface operations include accessing, at a Shell PCIe Bridge (SPB), an outbound transaction for a PCIe endpoint vendor IP or an inbound transaction for an SPB client. The SPB supports a shared common PCIe physical link based on a shared-link-interface comprising vendor-agnostic downstream custom interface and a vendor-specific upstream PCIe endpoint interface. The shared-link-interface operations further include processing the outbound transaction or the inbound transaction based on shared-link-interface services. In this way, processing transaction comprises executing shared-link-interface operations that provide protection enhancements associated with sharing a physical PCIe link. The shared-link-interface operations further include communicating the outbound transaction to the PCIe endpoint vendor IP or the inbound transaction to the SPB client.
