Abstract
Aspects of the present disclosure include methods and system for fast allocation of memory from fragmented memory. In one example, at a processor receives a request for an address to a buffer stored in a magazine associated with the processor. Upon determining that the magazine associated with the processor is empty, a request is made to a depot layer for additional memory. Upon determining that the depot layer cannot satisfy the request for the additional memory, executing a call to a slab layer for the additional memory. The slab layer identifies one or more partially-allocated slabs and generates a new magazine. A set of addresses correspond to buffers may be stored in the new magazine. A reference to the new magazine may be transferred from the slab layer to the depot layer. The reference to the new magazine may then be transferred from the depot layer to the processor.
