Asterinas is dedicated to maintaining compatibility with the Linux ABI,
|
|
|
|
|
ensuring that applications and administrative tools
|
|
|
|
|
designed for Linux can seamlessly operate within Asterinas.
|
|
|
|
|
While we prioritize compatibility,
|
|
|
|
|
it is important to note that Asterinas does not,
|
|
|
|
|
nor will it in the future,
|
|
|
|
|
support the loading of Linux kernel modules.

At the time of writing,

Asterinas supports over 226 Linux system calls for the x86-64 architecture,
|

|
|
|
which are summarized in the table below.
