问题
I try to understand the memory regions in the com.android.browser process [memory map below], and have a few questions:
For the address ranges without a pathname, what are mapped here?
There're multiple [stack:xxxx] regions, are they thread local stacks? If not, what are they? They seem to get mapped in many different locations scattered in the memory space.
If assuming the stack is at the top of the user space, then the user space memory is 2GB, the rest 2GB taken by the kernel space. Is it possible to see the memory map for the kernel space?
The

回答1:
(1) The unnamed regions could be anything. As one example, the dlmalloc implementation will use mmap() to allocate large regions (where "large" is configurable; might be 64K or 256K).
(2) The [stack:xxxx] stacks are thread stacks for the specified thread; each is 1MB with a guard page to trap over/underruns. They won't all be sequential because not all threads are started at the same time.
(3) The kernel starts at 0xc0000000. ASLR causes things to be placed somewhat randomly. There are various tools for poking at the Linux kernel.
(4) The dalvik-jit-code-cache is executable code. Note the 'x' (execute) flag is set.
