Android进程内存映射

Question

我试图理解 com.android.browser 进程中的内存区域 [下面的内存映射]，并有几个问题:

1. 对于没有路径名的地址范围，这里映射的是什么？

2. 有多个 [stack:xxxx] 区域，它们是本地线程吗堆栈？如果不是，它们是什么？他们似乎被映射到许多分散在内存空间中的不同位置。

3. 如果假设栈在用户空间的顶部，那么用户空间内存为2GB，其余2GB被内核空间占用。是可以看到内核空间的内存映射吗？

4. 59eb5000-59fb5000 r-xp 00000000 00:04 3972
/dev/ashmem/dalvik-jit-code-cache(已删除) 将被视为和码区一样？

Answer 1

(1) 未命名区域可以是任何东西。例如，dlmalloc 实现将使用 mmap() 分配大区域(其中“大”是可配置的；可能是 64K 或 256K)。

(2) [stack:xxxx] 栈是指定线程的线程栈；每个都是 1MB，带有保护页面以捕获溢出/欠载。它们不会都是顺序的，因为并非所有线程都同时启动。

(3) 内核从0xc0000000开始。 ASLR 使事物的放置有些随机。有各种工具可以用来查看 Linux 内核。

(4) dalvik-jit-code-cache 是可执行代码。请注意“x”(执行)标志已设置。
