Many of the segments will be shared between processes (such as libc text). Are you looking for all segments, or only unique segments? Do you want this for processes plus the kernel? Not all segments will have physical pages mapped. What do you want to do with this information?
At any rate, this will give you the number of VM (virtual memory) segments, including the kernel: # echo "::walk proc | ::print proc_t p_as | ::walk seg ! wc" | mdb -k max max > > > On Tue, Apr 22, 2008 at 8:23 PM, [EMAIL PROTECTED] > <mailto:[EMAIL PROTECTED]> <[EMAIL PROTECTED] > <mailto:[EMAIL PROTECTED]>> wrote: > > Hi Pradeep, > > > PRDEEP KUMAR wrote: > > Hi All, > > How can I see the memory range used by kernel in solaris > on X86 system? > How can I see the VA->PA mappings? > > If you could give me the commands would be better,Otherwise > also ok. > > # 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).
