Tenon v0.3.0 · TenonOS/Tenon

### v0.3.0
- 此版本主要实现静态页表重构，提供SMP多核启动、中断后调度能力，同时增加D9平台
- 发布日期：2024.12.24

### 新特性

#### Tenon支持SMP part 1：多核启动

##### LCPU结构体重构
 LCPU结构体中维护中断栈、异常栈、中断嵌套、上下文切换请求标识等字段，移除辅助栈字段，并独立维护CPU启动参数
- plat/common : refactoring the lcpu structure ([16](https://gitee.com/tenonos/tenon/pulls/16)) by [@sunhaoyi](https://gitee.com/yingyisunhaoyi) [@caicheng](https://gitee.com/cheng2000160)

##### 引导CPU初始化
 将首个执行启动程序的CPU视为引导CPU，记录其物理信息
- plat/common : Add the tn_bootstrap_cpu structure to help identify bootstrap cpu ([25](https://gitee.com/tenonos/tenon/pulls/25)) by @caicheng
- plat/common : Unify the process of bootstrap cpu decision ([63](https://gitee.com/tenonos/tenon/pulls/63)) by @caicheng

##### 添加CPU入口函数注册宏
 多核无调度器场景下，支持用户在编译期预设每个CPU的入口程序并存储至内存段
- plat/kvm,common : Add CPU entry function registration macros ([34](https://gitee.com/tenonos/tenon/pulls/34)) by @caicheng

##### 新增微库ukthread用于管理线程生命周期，重构微库uksched
 引入ukthread微库用于管理线程生命周期，优化uksched微库中的接口

- lib/uksched : Refactor Scheduler APIs ([71](https://gitee.com/tenonos/tenon/pulls/71)) by @caicheng

##### 中断后调度
 对ISR中的调度请求进行延迟处理，确保中断结束后再执行重调度
- lib/uksched : add reschedule point after isr is complete ([43](https://gitee.com/tenonos/tenon/pulls/43)) by @caicheng

##### SMP多核启动
 主核为从核执行逻辑上电，并通过核间中断唤醒从核
- lib/ukboot : Add SMP startup features ([18](https://gitee.com/tenonos/tenon/pulls/18)) by @caicheng

##### RK3568支持SMP多核启动
- plat/rk3568 : Adapts to the modification of the tn_bootstrap_cpu structure ([2](https://gitee.com/tenonos/plat-rk3568/pulls/2)) by @caicheng
- plat/rk3568 : Adapts to the SMP feature ([7](https://gitee.com/tenonos/plat-rk3568/pulls/7)) by @caicheng

#### TenonOS支持D9平台

##### Tenon适配D9
- plat/d9 : provide adaptive SemiDrive D9 board ([1](https://gitee.com/tenonos/plat-d9/pulls/1)) by [@wangguokun](https://gitee.com/wang-guo-kun)

##### 完善gic-v2/ns8250驱动以适配D9
- lib/ukintctlr, uktty : complete ns8250 and gic-v2 drivers for d9 ([67](https://gitee.com/tenonos/tenon/pulls/67)) by @wangguokun

### 优化

#### 静态页表重构
    不再使用编译期硬编码形式维护的静态页表。以memregion数组维护Memory信息，在编译期间生成静态页表。

##### Tenon静态页表重构
- lib/tnpaging,plat/common/arm,plat/kvm : refactor the static allocation page table ([59](https://gitee.com/tenonos/tenon/pulls/59)) by @wangguokun

##### D9静态页表重构
- plat/d9 : refactor the static page table ([2](https://gitee.com/tenonos/plat-d9/pulls/2)) by @wangguokun

##### RK3568静态页表重构
- plat/rk3568 : refactor the static page table ([5](https://gitee.com/tenonos/plat-rk3568/pulls/5)) by @wangguokun

#### 编译构建优化
 Tenon编译时支持通过命令行获取外部微库/驱动/平台子目录，并保证编译顺序
- build : Get the external lib/driver/plat directory in the makefile file instead of build.sh ([15](https://gitee.com/tenonos/tenon/pulls/15)) by @caicheng
- build/kconfig : add parse external lib dependency ([53](https://gitee.com/tenonos/tenon/pulls/53)) by @wangguokunn

#### 中断处理函数寻址优化
- driver/ukintctlr : Use gic-v3 irq handlers directly in el1_irq ([21](https://gitee.com/tenonos/tenon/pulls/21)) by @caicheng

#### 代码格式化工具更新
- ci : update code formatting tool ([62](https://gitee.com/tenonos/tenon/pulls/62)) by [@zhaohaidan](https://gitee.com/gloria-z)

#### 统一gic-v2/v3中sgi发送接口
- lib/intctlr : modify sgi sending api ([81](https://gitee.com/tenonos/tenon/pulls/81)) by @caicheng
