本文介绍如何利用mdb-k工具获取内核内存段的基本虚拟地址及大小，并演示了如何遍历内核页来获得物理页号。此外还提供了一个简单的方法来将内核虚拟地址转换为物理地址。

# echo "p0::pmap" | mdb -k

or

# echo "kas::walk seg | ::seg" | mdb -k

will give you base virtual address and virtual sizes for the kernel's
memory segments.

Walking the list of kernel pages to get physical page numbers:

# echo "kvp::walk page | ::print page_t p_pagenum" | mdb -k

should work (but may not be complete). In general, if you have a kernel
virtual address,
# echo "virtual_address::vtop" | mdb -k

will give you the physical address.
