[Qemu-devel] [PATCH V2 0/4] HMP: allow parsing for sub command

[Qemu-devel] [PATCH V2 0/4] HMP: allow parsing for sub command

[Wenchao Xia]

  These patches enhance HMP to allow it parse 2nd level of commands, such
as info sub command list, which means now foldered command with parameter
is possible.

V2:
  Follow the way supposed by Markus, which make the infrastructure knows
there is possible a 2nd level of command exist, instead of a hack. In this
way extention of command folder level is easy.
  Moved some code and better doc according to comments.
  Removed the patch about info snapshots, which will goto another serial.
V3:
  Move changelog position.
  Split out code moving patch.

Wenchao Xia (4):
  HMP: add QDict to info callback handler
  HMP: add infrastructure for sub command
  HMP: move define of mon_cmds
  HMP: add sub command table to info

[Qemu-devel] [PATCH V2 1/4] HMP: add QDict to info callback handler

[Wenchao Xia]

  This patch change all info call back function to take
additional QDict * parameter, which allow those command
take parameter. Now it is set to NULL at default case.

Signed-off-by: Wenchao Xia <xiawenc@linux.vnet.ibm.com>

[Qemu-devel] [PATCH V2 2/4] HMP: add infrastructure for sub command

[Wenchao Xia]

  This patch make parsing of hmp command aware of that it may
have sub command. Also discard simple encapsulation function
monitor_find_command() and qmp_find_cmd().
