Restarting a Driver Host

[Natalie Eleftheriades]

Hi all!

You can now restart manually restart a driver host by specifying the name of a driver.

This might be useful for debugging issues related to driver unbinding and rebinding. It’s also now the easiest way for you to check that your driver will behave correctly if a crash causes the driver host to automatically restart.

To get started, you can try restarting the e1000 driver on a NUC:

fx shell run fuchsia-pkg://fuchsia.com/restart-driver-hosts#meta/restart-driver-hosts.cmx /boot/driver/e1000.so 
Although restarting the e1000 driver may require you to close and rerun fx shell if you have it currently running.

If you need to find the name of a driver, try looking for it in dm dump.
