# scx_soryu
|
|
|
|
a port of the BMQ/LFBMQ scheduling policy onto [sched_ext](https://docs.kernel.org/scheduler/sched-ext.html).
|
|
the policy is pure BPF C; userspace is a thin Rust loader and more safer than normal scheduler.
|

|
| target, tested | Intel i5-3210m (Ivy Bridge, 2c/4t) | **verified** — bare metal, extended game + build sessions |
|
|
| target, untested | Ryzen 5 PRO 4650u (Renoir, 6c/12t) | not yet run |

## development
|
|
|
|
```sh
|
|
nix develop # clang, bpftool, rust, libbpf; kernel drift guard
|
|
```
|
|
|
|
run it by hand:
|
|
|
|
```sh
|
|
sudo ./target/release/scx_soryu
|
|
```
|
|
|
|
or as a NixOS service — see [`docs/service.md`](docs/service.md).
|
|
|
|
test VM (a smoke test, not a benchmark — measure on bare metal):
|
|
|
|
```sh
|
|
nix build .#nixosConfigurations.testvm.config.system.build.vm
|
|
./result/bin/run-nixos-vm
|
|
```
|

|
|
## kernel
|
|
|
|
audited series is **7.1.x**. the devShell refuses to open outside it.
|
|
`vmlinux.h` is generated from the running kernel's BTF and is not committed.
