一个独立的内核模块，用于测试64bit的原子操作，即针对atomic64.c的测试程序
Linux 内核同步机制--ATOMIC_INIT ()

对于atomic_t类型，宏通常定义如下：c深色版本这表示它接受一个整数值i作为参数，并将其设置为原子变量的初始值。是一个宏，用于在声明时初始化原子变量。原子变量提供了对整数操作的原子性保证，适用于多线程环境下的计数器和状态标记。结合原子操作函数（如atomic_setatomic_inc等），可以实现高效且无锁的同步控制。在编写内核模块或驱动程序时，合理利用原子变量可以简化并发编程，提高系统稳定性和性能。

atomic64_cmpxchg、atomic_cmpxchg是宏定义，第一个参数使用强制类型转换，移植代码到64位系统时容易入坑。

本文用于实现64位的原子操作，主要方式是通过自旋锁来实现原子操作。当然对于指令层面支持64位操作的CPU来说，不需要本文的实现。共16个自旋锁，每个锁占据一个缓存块大小（L1）。初始化时锁都没有占用。lock_addr函数，根据传入的64位变量的内存地址，计算1个hash值，使用此值来定位1个自旋锁，用这把锁来保护此64位变量的读写。...
Linux(内核剖析):29---内核同步之（原子操作（原子整数操作(atomic_t、atomic64_t)、原子位操作））

一、原子操作概述 原子操作可以保证指令以原子的方式执行——执行过程不被打断。众所周知，原子原本指的是不可分割的微粒，所以原子操作也就是不能够被分割的指令 Linux内核提供的原子接口 内核提供了两组原子操作接口——一组针对整数进行操作，另一组针对单独的位进行操作 在Linux支持的所有体系结构上都实现了这两组接口。大多数体系结构会提供支持原子操作的简单算术指令。而有些体系结构确实缺少简单的...

Linux学习---atomic_inc 原子操作

atomic_inc(&v)对变量v用锁定总线的单指令进行不可分解的"原子"级增量操作，避免v的值由于中断或多处理器同时操作造成不确定状态。 原子操作 　　所谓原子操作，就是该操作绝不会在执行完毕前被任何其他任务或事件打断，也就说，它的最小的执行单位，不可能有比它更小的执行单位，因此这里的原子实际是使用了物理学里的物质微粒的概念。 　　原子操作需要硬件的支持，因此是架构相关的，其API和原子类型的定义都定义在内核源码树的include/asm/atomic.h文件中，它们都使用汇编语言实现，因为C语

1. 如果使用源码编译 `ecl_core`，需确保将其放入 `~/robot_ws/src` 并重新编译： ```bash cd ~/robot_ws/src git clone https://github.com/stonier/ecl_core.git -b release/${ROS_DISTRO}/ecl_core cd ~/...
macos编译protobuf2.5.0提示unknown type name ‘Atomic64‘； did you mean ‘Atomic32‘

类型在 macOS 平台上并不是默认定义的类型。可能是因为在你的系统上，某些库或文件缺少必要的定义。为解决这个问题，可以手动定义。三、重新编译 protobuf 库。在重新编译之前，请确保已经清除之前生成的文件。在macos编译protobuf2.5.0，make的时候出现。命令清除之前生成的文件，然后再运行。命令重新编译 protobuf 库。二、在文件开头添加以下代码。
