补档

由于 AKR 社区及其下载站已挂，于是在此处补档一个 Horizon Kernel 。
先前发布的版本是 B1 到 R17 ，由于旧的代码基本上都被 force push 掉了，因此只能补档一个之前不存在的 R18 版本。

R18 版本在 R17 的基础上进行了一些上游更新和稳定性改进，不过都是很早以前的修改了，具体细节已经记不清了。
另外还修复了 R17 上，设备温度高时可能导致部分处理器无负载的问题，这个是刚改的所以记得非常清楚。
还有，如果你还记得我当年说 R18 版本里会有什么，那确实是有的，我没忘，你找找。

下载：

用法：
先 root ，再用“内核刷入器”刷内核，有需要的话可以用“内核控制器”调节。

编译方法

首先，创建工作空间，获取内核本体代码：

$ mkdir workspace
$ cd workspace
$ git clone https://github.com/libxzr/android_kernel_oneplus_sm8250 -b oos11/final

然后，获取内核压缩包的代码：

$ git clone https://github.com/libxzr/AnyKernel3 -b op8/11

然后，获取编译工具链，此处推荐 Horizon Clang ，R18 版本是基于其 16.x 版本编译测试的。
工具链在解压后放在 workspace 的 clang 目录处，不可有额外的目录嵌套，即需要确保 workspace/clang/bin/clang 是编译器的可执行文件。

然后，获取内核本体中的 submodules：

$ cd android_kernel_oneplus_sm8250
$ git submodule init
$ git submodule update

参考的编译脚本：

horizon_build.sh

脚本要求的目录结构如下：

workspace
├── AnyKernel3
├── android_kernel_oneplus_sm8250
│   ├── horizon_build.sh
├── clang
│   ├── bin
│   │   ├── clang

workspace 的目录名称是无所谓的，只需要确保 AnyKernel3 和 clang 在内核源码文件夹的同级目录下即可，编译脚本则放在内核源码文件夹中。

然后在内核源码文件夹中执行命令即可：

# 编译所有机型/系统的版本
./horizon_build.sh
# 编译所有机型/系统的版本（干净编译）
./horizon_build.sh -c

# 编译一加 8 的版本（仅氢氧）
./horizon_build.sh op8
# 编译一加 8 的版本（仅氢氧）（干净编译）

# 编译一加 8P 的版本（仅氢氧）

  • 内联编译了所有内核模块
  • 采用 lz4 作为 ZRAM 算法
  • 移除大量调试代码与未使用驱动
  • 支持使用 BBR 作为 TCP 拥塞控制算法（需要手动调整），默认采用 Westwood+ 算法
  • 采用 fq_codel 作为默认流控算法
  • 采用 128kB 的 IO 预读
  • 采用 urandom 作为默认的熵生成器
  • 采用 schedhorizon 作为默认的 CPU 调速器
  • GPU 默认超频到 670 MHz

后记

COS 13 的内核还是有希望的，因为我原来觉得官核挺好的，结果现在又发现挺烂的。
