  10         This controls whether arguments in guest processes should be shown on
  11         the host's ps output.
  12         Enabling this option hinders debugging on some recent GDB versions
  13         (because GDB gets "confused" when we do an execvp()). So probably you
  14         should disable it.

  16 config PT_PROXY
  17         bool "Enable ptrace proxy"
  18         depends on XTERM_CHAN && DEBUG_INFO && MODE_TT
  19         help
  20         This option enables a debugging interface which allows gdb to debug
  21         the kernel without needing to actually attach to kernel threads.
  22         If you want to do kernel debugging, say Y here; otherwise say N.

  28         This allows profiling of a User-Mode Linux kernel with the gprof
  29         utility.

  31         See <http://user-mode-linux.sourceforge.net/gprof.html> for more
  32         details.
  33
  34         If you're involved in UML kernel development and want to use gprof,
  35         say Y.  If you're unsure, say N.

  41         This option allows developers to retrieve coverage data from a UML
  42         session.

  54         help
  55         This adds some system debugging to UML, including keeping a ring buffer
  56         with recent system calls and some global and per-task statistics.
