Interpreting "pidin mem" output

Hi,
How to interpret following “pidin mem” output ?

=====================================================

655439 1 .//test 10f REPLY 12K 184K
32K(516K)*
ldqnx.so.2 @b0300000 300K 16K


mem @816be000 28K 30M
mem @82b5c000 36K 560K


/dev/mem @45c0c000 ( 0) 4096
/dev/mem @60000000 ( 0) 32M

  • Does “mem” correspond to mmapped memory and “/dev/mem” correspond to
    device mapped memory ?
  • Also “mem” has associated code & data, while “/dev/mem” has only data
    associated ?
  • How to identify which private and shared memory usage ?



    thanks,
    Sachin
