| * DOC: QTest Protocol | |
| * | |
| * Line based protocol, request/response based. Server can send async messages | |

| * Clock management: | |
| * """"""""""""""""" | |
| * | |
| * The qtest client is completely in charge of the QEMU_CLOCK_VIRTUAL. qtest commands | |
| * let you adjust the value of the clock (monotonically). All the commands | |
| * return the current value of the clock in nanoseconds. | |
| * | |
| * If the commands FAIL then time wasn't advanced which is likely | |
| * because the machine was in a paused state or no timer events exist | |
| * in the future. This will cause qtest to abort and the test will | |
| * need to check its assumptions. | |
| * | |
| * .. code-block:: none | |
| * | |
| * > clock_step | |
| * < OK VALUE | |
| * | |
| * Advance the clock to the next deadline. Useful when waiting for | |
| * asynchronous events. | |
| * | |
| * .. code-block:: none | |

| * > clock_step NS | |
| * < OK VALUE | |
| * | |
| * Advance the clock by NS nanoseconds. | |
| * | |
| * .. code-block:: none | |
| * | |
| * > clock_set NS | |
| * < OK VALUE | |
| * | |
| * Advance the clock to NS nanoseconds (do nothing if it's already past). | |

| * ADDR, SIZE, VALUE are all integers parsed with strtoul() with a base of 0. | |
| * For 'memset' a zero size is permitted and does nothing. | |
| * | |
| * DATA is an arbitrarily long hex number prefixed with '0x'. If it's smaller | |

| * sequence. | |
| * | |
| * B64_DATA is an arbitrarily long base64 encoded string. | |
| * If the sizes do not match, the data will be truncated. | |
