PCI Device Reference Counting
This proposal has been accepted as a session.
One Line Summary
Discussion of synchronization issues with device addition and removal
Abstract
There are several open issues related to races and deadlocks when adding or removing devices or rescanning buses. PCI currently doesn’t have a consistent strategy for managing data structure lifetimes. Jiang Liu and Gu Zheng are improving PCI reference counting to address these problems.
