# liumOS
[](https://circleci.com/gh/hikalium/liumos)
[](https://opensource.org/licenses/MIT)
A toy operating system which supports NVDIMM natively.
## Requirements
### Common
[Install Rust toolchain](https://www.rust-lang.org/tools/install)
Check the installation (below is an example output):
```
$ cargo --version
cargo 1.46.0 (149022b1d 2020-07-17)
```
Then, install nightly toolchain and cargo-xbuild for cross compiling.
```
rustup toolchain install nightly-x86_64-unknown-linux-gnu
rustup component add rust-src
```
### macOS
```
brew install wget cmake qemu llvm dosfstools
```
### Ubuntu 20.04
```
sudo apt install wget cmake qemu-system-x86 clang-8 lld-8 libc++-8-dev libc++abi-8-dev clang-format
```
## Prepare tools and libraries
Move to the root of this source tree. Then:
```
make tools
make prebuilt
```
## How to build
```
make
```
## Run on QEMU
This repository contains [OVMF](https://github.com/tianocore/tianocore.github.io/wiki/OVMF) binary for UEFI emulation.
```
make run
```
You can connect serial console using telnet
```
telnet localhost 1235
```
### Run flags
Flags can be specified for `make run` command. Please check [qemu.mk](./qemu.mk) for more details.
Example:
```
make run GUI=n GDB=nosuspend
```
- `GUI`
- `=y`: Enable GUI
- `=n`: Disable GUI (enable VNC server)
- `GDB`
- `=n`: Disable gdb server in QEMU
- `=suspend_on_boot`: Enable gdb server and wait for a connection on startup
- `=nosuspend`: Enable gdb server and startup the machine normally without waiting for a gdb connection
## Setup tap interface (for linux)
`make run` boots liumOS on QEMU with a tap interface on Linux host.
To avoid running QEMU with sudo, you need to setup a tap interface in advance.
```
sudo ip tuntap add dev tap0 mode tap user $USER
sudo ip link set dev tap0 master br0
sudo ip link set dev tap0 up
```
example output with bridge `br0` connected to `eno1`
```
$ ip a | grep -e br0 -e tap0
2: eno1: mtu 1500 qdisc mq master br0 state UP group default qlen 1000
4: br0: mtu 1500 qdisc noqueue state UP group default qlen 1000
inet 10.10.10.93/24 brd 10.10.10.255 scope global dynamic br0
6: tap0: mtu 1500 qdisc fq_codel master br0 state UP group default qlen 1000
```
### Setup bridge interface
#### global, persistent
```
network:
ethernets:
eno1:
dhcp4: false
dhcp6: false
bridges:
br0:
interfaces: [ eno1 ]
dhcp4: true
version: 2
```
