Laptops commonly include + hot-pluggable PCIe as either an ExpressCard slot or + a Thunderbolt interface. ExpressCard has built-in USB support + that is already supported by &os;, but ExpressCard PCIe + devices like Gigabit Ethernet adapters and eSATA cards are + only supported when they are present at boot, and removal may + cause &os; to crash.</p> + + <p>The goal of this project is to allow these devices to + be inserted and removed while &os; is running. The work + will provide the basic infrastructure to support adding and + removing devices, though it is expected that additional work + will be needed to update individual drivers to support + hot-plug.</p> + + <p>Current testing is focused on getting a simple UART + device functional.
