Abstract
Methods and apparatus for dynamic packet pool configuration in networking stack architectures. Unlike prior art monolithic memory allocations, embodiments of the present disclosure enable packet pools associated with non-kernel space applications to dynamically allocate additional memory allocations to a given non-kernel space application, or conversely, de-allocate memory allocations to a given non-kernel space application. Variants also disclose the splitting up of a memory allocation into device accessible portions and kernel accessible portions. Other variants disclose sizing certain segment allocations so as to be a multiple of a physical address page size. Such a variant enables a single input/output (I/O) bus address lookup for the given segment so as to minimize look up costs associated with an I/O lookup for the given segment.
