Commands for Symbol Conversion and Lookup

Commands for Symbol Conversion and Lookup

Command	Example	Operation
hx name	hx dk_read dk_read 0xffffffff882b0510	The name is looked up on the symbol table and if it is found, its address is displayed.
lkaddr addr	lkaddr 0x882b0510 0x882af910 lockdisptab 0x882b0510 dk_read 0x882b051c dk_write	Symbols near to the specified addr are listed. Use this command to find out the symbolic location of an unexpected stop.
lkup letters	hx dk_rea 0x880d5f10 dk_readcap 0x882b0510 dk_read 0x332b0528 dk_readcapacity	Every symbol that contains the specified letters at any point is listed. There is no way to anchor the search to the beginning or end of the name.
msyms ident	msyms 13 Symbols for module 13 (prefix tcl) tclinit 0xc0403d9c tclmversion 0xc0405fe0	The symbols for the loadable module ident are listed. Use the ml command with no arguments to list all modules and their ident numbers.
nm addr	nm 0xc0403da0 0xc0403da0 tclinit+0x4	The symbol nearest to the specified addr is listed.

Note: When symmon displays an address it normally shows a full 64 bits. In a 32-bit kernel, the most-significant 32 bits of a kernel virtual address are all-binary-1, from extension of the sign bit of the 32-bit address--as shonw in the example of hx in Table 11-1. When you enter an address to a command in a 32-bit system, you need to type only the significant 32-bit value.
