Android进程内存映射

Question

我尝试了解com.android.browser进程[下面的内存映射]中的内存区域，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，它们是线程本地的吗 堆栈？如果不是，它们是什么？他们似乎被映射到许多 分散在内存空间的不同位置。

3. 如果假设堆栈位于用户空间的顶部，则 用户空间内存为 2GB，其余 2GB 由内核空间占用。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 (deleted) 将被视为 和代码区域一样吗？

Answer 1

(1) 未命名的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] 堆栈是指定线程的线程堆栈；每个都是 1MB，带有一个保护页面来捕获溢出/欠载。它们不会都是连续的，因为并非所有线程都同时启动。

(3) 内核从 0xc0000000 开始。 ASLR 会导致事物的放置有些随机。有多种工具可用于查看 Linux 内核。

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