为什么使用write_lock_irq而不是write_lock用于tasklist_lock?(Why write_lock_irq is used rather then write_lock for the tasklist_lock?)

在Linux内核中,读/写自旋锁用于同步对任务列表的访问。 然而,read_(un)lock用于读取,write_(un)lock_irq用于写入。 为什么在锁定写入时需要禁用中断?


In the Linux Kernel, read/write spin lock is used to synchronize access to the list of the tasks. However whereas read_(un)lock are used for reading, write_(un)lock_irq are used for writing. Why is it needed to disable interrupts while locking for writing?

最满意答案

GLES2-Anchor分支中没有IAreaShape类。 您可能正在混合一些较旧的库。 尝试再次下载源代码。 请注意,您的PhysicsBox2D扩展也必须来自GLES2-Anchor分支。 此外,您不应该将任何jar添加到buildpath。 你应该只看到:

  • Android XYZ
  • Android依赖项

并在项目配置的“Android”部分添加库。


There is no IAreaShape class in the GLES2-Anchor branch. You are probably mixing some older libraries. Try downloading sources again. Note that your PhysicsBox2D extension must be from GLES2-Anchor branch too. Also, you should not add any jars to buildpath. You should see only:

  • Android X.Y.Z
  • Android Dependencies

And add libraries in the "Android" part of your project configuration.
