See [Travis script ](./.travis.yml ) for details.
### How to run
```bash
$ rustup component add rust-src
$ cargo install cargo-xbuild bootimage
```
```bash
$ git clone https://github.com/rcore-os/rCore.git --recursive
$ cd rCore/user
$ make sfsimg arch={riscv32,riscv64,x86_64,aarch64} # requires x86_64-linux-musl-gcc or musl-gcc
$ cd ../kernel
$ make run arch={riscv32,riscv64,x86_64,aarch64} mode=release
$ make run arch=x86_64 mode=release pci_passthru=0000:00:00.1 # for ixgbe real nic, find its pci (bus, dev, func) first
```
