oeqa qemurunner.py: try to avoid reading one character at a time

2023-02-24T16:41:46+00:00

Read from serial console with a small delay to bundle data to e.g. full lines. Reading one character at a time is not needed and causes busy looping.

oeqa qemurunner.py: add timeout to QMP calls

2023-02-24T16:41:46+00:00

When a qemu machine hangs, the QMP calls can hang for ever too, and when this happens any failing test commands from ssh runner may be followed by dump_monitor() calls which then also hang. Hangs followed by hangs. Use runqemutime at setup and run_monitor() specific timeout for later calls.

oeqa qemurunner: read more data at a time from serial

2023-02-24T16:41:46+00:00

Use a short sleep to bundle serial console reads so that we are not reading one character at a time which reduces busy looping.

oeqa/qemurunner: do not use Popen.poll() when terminating runqemu with a signal

2023-02-15T21:46:56+00:00

This does not actually guarantee that the child runqemu process has completely exited: poll() may return prematurely while the SIGTERM handler in runqemu is still running. This thwarts the rest of the processing, and may terminate the handler before it completes. Use Popen.communicate() instead: this is what python documentation recommends as well: https://docs.python.org/3/library/subprocess.html#subprocess.Popen.communicate (From OE-Core rev: 88e7bac0f06d4f12cd6f078d37e4e9975871860f) Signed-off-by: Alexander Kanavin Signed-off-by: Richard Purdie (cherry picked from commit cd3e55606c427287f37585c5d7cde936471e52f4) Signed-off-by: Steve Sakoman Signed-off-by: Richard Purdie

oeqa: qemurunner: Report UNIX Epoch timestamp on login

2022-09-16T16:53:23+00:00

Updates the log message printed when login banner is seen in QEMU to report the UNIX Epoch time in addition to the human readable time. This makes it much easier and accurate to correlate logs with the guest, in particular with the guest journalctl which prints log timestamps in human readable format and the oeqa SSH debug logging which prints the UNIX Epoch.

qemuboot/runqemu: fully form the ip= kernel parameter

2022-01-11T10:53:44+00:00

New systemd is actually parsing this in systemd-network-generator and fails if it is not fully formed.

oeqa/qemurunner: Use oe._exit(), not sys.exit()

2021-09-26T13:36:48+00:00

sys.exit will cause finally statements and other code to run at exit. Since we're using os.fork() here, os._exit() is apprioriate in this codepath. (From OE-Core rev: ec08498ff29de9ccd23be88b9d7af3dab6bbb81e) Signed-off-by: Richard Purdie
