Hi,
This patch adds new test for virtio_console. It supports booth, serialport and
console, virtio_console types and it contains three tests:
1) smoke
2) loopback
3) perf
Before any tests are executed it starts the machine with required number of
virtio_consoles. Than it allows user to run all three tests. Using the
parameters user can control which tests are executed and what setting is used.
All tests supports multiple run using ';' separated list of settings. Most of
the settings are optional only. The mandatory ones are written in CAPITALS.
ad1) virtio_console_smoke format:
$VIRTIO_CONSOLE_TYPE:$custom_data
It creates a loopback via $VIRTIO_CONSOLE_TYPE console and sends $custom_data.
If the received data match the original test pass
ad2) virtio_console_loopback format:
$source_console_t...@$buffer_length:$destination_console1_t...@$buffer_length:...:$destination_consolex_t...@$buffer_length:$loopback_buffer_length
Creates loopback between the $SOURCE_CONSOLE_TYPE console and all following
$DESTINATION_CONSOLEn_TYPE consoles. Than it sends data by $buffer_length to
the source port. The loopback resends the data by $loopback_buffer_length to
all destination consoles. The test listens on the destination consoles and
controls the received data.
NOTE: in the debug mode you can see the send/received data's buffers in every
second during the test.
ad3) virtio_console_perf format:
$virtio_console_t...@$buffer_size:$test_duration
First it sends the prepared data in a loop over $VIRTIO_CONSOLE_TYPE console
from host to guest. Guest only reads all the data and throw them away. This
part runs $test_duration seconds.
Second it does the same from guest to host.
For booth runs it provides information of minimum/median/maximum throughput and
guest/host average loads.
Best regards,
Lukas Doktor

Just a note about kernels:
serialport works great but console have big issues. Use kernels >=
2.6.35 for testing.
