block: qemu-iotests - add common.qemu, for bash-controlled qemu tests
This creates some common functions for bash language qemu-iotests
to control, and communicate with, a running QEMU process.
4 functions are introduced:
1. _launch_qemu()
This launches the QEMU process(es), and sets up the file
descriptors and fifos for communication. You can choose to
launch each QEMU process listening for either QMP or HMP
monitor. You can call this function multiple times, and
save the handle returned from each. The returned handle is
in $QEMU_HANDLE. You must copy this value.
Commands 2 and 3 use the handle received from _launch_qemu(), to talk
to the appropriate process.
2. _send_qemu_cmd()
Sends a command string, specified by $2, to QEMU. If $3 is
non-NULL, _send_qemu_cmd() will wait to receive $3 as a
required result string from QEMU. Failure to receive $3 will
cause the test to fail. The command can optionally be retried
$qemu_cmd_repeat number of times. Set $qemu_error_no_exit
to not force the test the fail on exit; in this case,
$QEMU_STATUS[$1] will be set to -1 on failure.
3. _timed_wait_for()
Waits for a response, for up to a default of 10 seconds. If
$2 is not seen in that time (anywhere in the response), then
the test fails. Primarily used by _send_qemu_cmd, but could
be useful standalone, as well. To prevent automatic exit
(and therefore test failure), set $qemu_error_no_exit to a
non-NULL value. If $silent is a non-NULL value, then output
to stdout will be suppressed.
4. _cleanup_qemu()
Kills the running QEMU processes, and removes the fifos.

in $QEMU_HANDLE. You must copy this value.
Commands 2 and 3 use the handle received from _launch_qemu(), to talk
to the appropriate process.
2. _send_qemu_cmd()
Sends a command string, specified by $2, to QEMU. If $3 is
non-NULL, _send_qemu_cmd() will wait to receive $3 as a
required result string from QEMU. Failure to receive $3 will
cause the test to fail. The command can optionally be retried
$qemu_cmd_repeat number of times. Set $qemu_error_no_exit
to not force the test the fail on exit; in this case,
$QEMU_STATUS[$1] will be set to -1 on failure.
3. _timed_wait_for()
Waits for a response, for up to a default of 10 seconds. If
$2 is not seen in that time (anywhere in the response), then
the test fails. Primarily used by _send_qemu_cmd, but could
be useful standalone, as well. To prevent automatic exit
(and therefore test failure), set $qemu_error_no_exit to a
non-NULL value. If $silent is a non-NULL value, then output
to stdout will be suppressed.
4. _cleanup_qemu()
Kills the running QEMU processes, and removes the fifos.

block: qemu-iotests - add common.qemu, for bash-controlled qemu tests
This creates some common functions for bash language qemu-iotests
to control, and communicate with, a running QEMU process.
4 functions are introduced:
1. _launch_qemu()
This launches the QEMU process(es), and sets up the file
descriptors and fifos for communication. You can choose to
launch each QEMU process listening for either QMP or HMP
monitor. You can call this function multiple times, and
save the handle returned from each. The returned handle is
in $QEMU_HANDLE. You must copy this value.
Commands 2 and 3 use the handle received from _launch_qemu(), to talk
to the appropriate process.
2. _send_qemu_cmd()
Sends a command string, specified by $2, to QEMU. If $3 is
non-NULL, _send_qemu_cmd() will wait to receive $3 as a
required result string from QEMU. Failure to receive $3 will
cause the test to fail. The command can optionally be retried
$qemu_cmd_repeat number of times. Set $qemu_error_no_exit
to not force the test the fail on exit; in this case,
$QEMU_STATUS[$1] will be set to -1 on failure.
3. _timed_wait_for()
Waits for a response, for up to a default of 10 seconds. If
$2 is not seen in that time (anywhere in the response), then
the test fails. Primarily used by _send_qemu_cmd, but could
be useful standalone, as well. To prevent automatic exit
(and therefore test failure), set $qemu_error_no_exit to a
non-NULL value. If $silent is a non-NULL value, then output
to stdout will be suppressed.
4. _cleanup_qemu()
Kills the running QEMU processes, and removes the fifos.
