KFlags: Pass flags to kernel #44

Closed dancrossnyc closed 3 months ago

dancrossnyc commented 6 months ago

Arrange to pass flags to the loaded kernel. These mirror the flags we could send via IPCC, as well as a "machine type" which (nominally) tells the loaded kernel what kind of machine it will run on. This allows us to tell the kernel that we're running on, e.g., a dev machine based on a reference design in the same image we would use on an Oxide machine, where we use the IPCC protocol to communicate with a service processor.

We can specify different combinations of things using flags and machine types using cargo features.

Tested on sn14.

This has been obviated by Andy's work on platform detection in illumos. Closing.
