11 | QMP Supported Commands | |
12 | ---------------------- | |
13 | ||
14 | This document describes all commands currently supported by QMP. | |
15 | ||
16 | Most of the time their usage is exactly the same as in the user Monitor, this | |
17 | means that any other document which also describe commands (the manpage, | |
18 | QEMU's manual, etc) can and should be consulted. | |
19 | ||
20 | QMP has two types of commands: regular and query commands. Regular commands | |
21 | usually change the Virtual Machine's state someway, while query commands just | |
22 | return information. The sections below are divided accordingly. | |
23 | ||
24 | It's important to observe that all communication examples are formatted in | |
25 | a reader-friendly way, so that they're easier to understand. However, in real | |
26 | protocol usage, they're emitted as a single line. | |
27 | ||
28 | Also, the following notation is used to denote data flow: | |
29 | ||
30 | -> data issued by the Client | |
31 | <- Server data response | |
32 | ||
33 | Please, refer to the QMP specification (QMP/qmp-spec.txt) for detailed | |
34 | information on the Server command and response formats. | |
35 | ||
36 | NOTE: This document is temporary and will be replaced soon. | |

38 | 1. Stability Considerations |
39 | =========================== | |
40 | ||
41 | The current QMP command set (described in this file) may be useful for a | |
42 | number of use cases, however it's limited and several commands have bad | |
43 | defined semantics, specially with regard to command completion. | |
44 | ||
45 | These problems are going to be solved incrementally in the next QEMU releases | |
46 | and we're going to establish a deprecation policy for badly defined commands. | |
47 | ||
48 | If you're planning to adopt QMP, please observe the following: | |
49 | ||
50 | 1. The deprecation policy will take efect and be documented soon, please | |
51 | check the documentation of each used command as soon as a new release of | |
52 | QEMU is available | |
53 | ||
54 | 2. DO NOT rely on anything which is not explicit documented | |
55 | ||
56 | 3. Errors, in special, are not documented. Applications should NOT check | |
57 | for specific errors classes or data (it's strongly recommended to only | |
58 | check for the "error" key) | |
59 | ||
60 | 2. Regular Commands | |
b40292e7 JK |
61 | =================== |
62 | ||
63 | Server's responses in the examples below are always a success response, please | |
64 | refer to the QMP specification for more details on error responses. | |

472 | Physical memory dump starting at @var{addr}. |
473 | ||
474 | @var{fmt} is a format which tells the command how to format the | |
475 | data. Its syntax is: @option{/@{count@}@{format@}@{size@}} | |
476 | ||
477 | @table @var | |
478 | @item count | |
479 | is the number of items to be dumped. | |
480 | ||
481 | @item format | |
482 | can be x (hex), d (signed decimal), u (unsigned decimal), o (octal), | |
483 | c (char) or i (asm instruction). | |
484 | ||
485 | @item size | |
486 | can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86, | |
487 | @code{h} or @code{w} can be specified with the @code{i} format to | |
488 | respectively select 16 or 32 bit code instruction size. | |
