Testing or Running an OS Project
OSDK allows for convenient building, running, and testing of an OS project. The following example shows the typical workflow.
Suppose you have created a new kernel project named myos
and you are in the project directory:
cargo osdk new --kernel myos && cd myos
Build the project
To build the project and its dependencies, simply type:
cargo osdk build
Run the project
To launch the kernel with QEMU, use the following command:
cargo osdk run
OSDK will boot the kernel and initialize OS resources like the console for output, and then hand over control to the kernel entry point to execute the kernel code.
Note: Only kernel projects (the projects
that defines the function marked with #[aster_main])
can be run;
library projects cannot.
Test the project
To run the kernel mode tests, use the following command:
cargo osdk test
OSDK will run all the kernel mode tests in the crate.
If you want to run a specific test with a given name,
for example, if the test is named foo,
use the following command:
cargo osdk test foo
Options
Both build, run, and test commands accept options
to control their behavior, such as how to compile and
launch the kernel.
The following documentations provide details on
all the available options:
