PolkaKernel

⚠️ This crate is work-in-progress. Expect API changes. ⚠️

This is Linux syscall abstraction layer for PolkaVM/CoreVM that translates Linux system calls to PolkaVM/CoreVM host-calls. The host-calls are abstracted away with traits and can easily be replaced by any meaningful implementation. For example, you can read/write files from/to memory instead of on-disk file system.

The main use case is to support running arbitrary programs written for Linux on PolkaVM/CoreVM without code rewrite. To accomplish that one needs to build the program using PolkaPorts toolchain and then run it via provided "player" tool (work-in-progress). Up-to-date instructions are in the PolkaPorts repository.
