PCI Express (PCIe) hot-plug is used on both laptops and + servers to allow peripheral devices to be added or removed while + the system is running. Laptops commonly include hot-pluggable + PCIe as either an ExpressCard slot or 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 their removal may cause &os; to crash.

+ +

The goal of this project is to allow these devices to be + inserted and removed while &os; is running. This 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.

+ +

Current testing is focused on getting a simple UART device + functional. Basic hot swap is currently functional.

+ +

A set of the patches for the work done in this project is + now available on github.com. +

+ + + + The FreeBSD Foundation + + + + +

Get suspend/resume functional by save/restoring the necessary + registers. This should be addressed by r281874.

+
+ + +

Make sure that upon suspend, devices are removed so that we + are not fooled if they are replaced with different devices while + the machine is suspended.

+
+ + +

Improve how state transitions are handled, possibly by + using a proper state machine.
