Allocation of physically-contiguous memory buffers is required by many device drivers, but it cannot always be reliably done on long-running Linux systems. That leads to all kinds of unsatisfying ...

This article is part of the LWN Porting Drivers to 2.6 series. The 2.5 development series has brought relatively few changes to the way device drivers will allocate and manage memory. In fact, most ...

“Fragmented memory” describes all of a system’s unusable free memory. These resources remain unused because the memory allocator responsible for allocating them cannot make the memory available. This ...

Editor's Note: Embedded Systems Architecture, 2nd Edition, is a practical and technical guide to understanding the components that make up an embedded system’s architecture. Offering detailed ...

If your production Linux system is logging memory allocation failures, it might still be able to keep running. But developers want to keep an eye on which code can survive a shortage of memory. In ...

Memory allocation to specific neurons (neuronal allocation) and synapses (synaptic allocation) in a neurocircuit is not random; instead, specific mechanisms determine which synapses and neurons go on ...
