slOS

silly little operating system

Hosted mode

% cargo run -p slos-hosted -- kernel

Optionally:

• Enabling the init_examples feature will do some extra runtime tests, including filesystem device node tests (which print to the console)
• Setting RUST_LOG=trace will get tracing messages from everything except the virtual interrupt dispatcher
• Setting RUST_LOG=trace,slos_hosted::host::interrupts=trace will get tracing messages from everything

To run the hosted kernel in "I want all the debugging!" mode, this is what you want:

% env RUST_LOG="trace,slos_hosted::host::interrupts=trace" cargo run -p slos-hosted --features init_examples -- kernel

The hosted debugging REPL

% cargo run -p slos-hosted -- repl

As an example:

slos-hosted> help
b: echo
fs: file-read, file-write-test, …

slos-hosted> b echo hello world!
hello world!

slos-hosted> fs mount-new-memoryfs /
slos-hosted> fs mount-list
/ - Some(UnsafeContainer(SimpleMemoryFs { … }))

slos-hosted> fs file-write-test /test
slos-hosted> fs file-read /test
[bytes] [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100, 33]
[string] "hello world!"

slos-hosted> exit
