qemurunner: Fix stack trace generation in exception handler

2024-12-09T15:23:28+00:00

Qemurunner exception handling code currently formats the stack trace using traceback.format_exception(), with parameters introduced in python 3.10. This will fail on platforms with an older python version. Change this to the old parameter order, still supported in current python versions. https://docs.python.org/3/library/traceback.html#traceback.format_exception Fixes [YOCTO #15675] (From OE-Core rev: 5f9ecf5f210e967594069f172728fd5b4d5b4f1d) Signed-off-by: Mathieu Dubois-Briand Signed-off-by: Richard Purdie

qemurunner: Clean up serial_lock handling

2024-10-14T20:42:17+00:00

Avoid "RuntimeError: release unlocked lock" since the lock shouldn't be locked even in the error path. Add a try/finally path to ensure this. (From OE-Core rev: b0732ee009ca47580d1d2ad75334f4aa50e6efd5) Signed-off-by: Richard Purdie

oeqa: support passing custom boot patterns to runqemu

2024-10-11T14:57:44+00:00

This allows defining non-standard patterns from QEMU tests just as they are already supported by the testimage.bbclass. Will allow testing non-Linux shells in QEMU, too (e.g. a U-Boot shell or another bootloader shell).

oeqa/utils/qemurunner: support ignoring vt100 escape sequences

2024-10-11T14:57:44+00:00

If we talk to terminals that like colors, we need to ignore the vt100 escape sequences when matching strings. An unprocessed barebox console prompt would e.g. look like: ESC[1;32mbarebox@ESC[1;36mARM QEMU virt64:/ESC[0m where we cannot match for something like "barebox@ARM QEMU virt64:/". The same applies to colored Linux terminal output of course. The "\x1b\[" from the regex catches the standard start of ANSI escape sequence while the rest catches the actual command code executed.

qemurunner.py: Fix error on calls to run_monitor

2024-03-07T17:27:51+00:00

A change in QEMUMonitorProtocol.cmd() requires that we either pass in kwargs instead of an argument dict or move to cmd_raw() cmd() was renamed to cmd_raw() (and command() was renamed to cmd()) See: https://github.com/qemu/qemu/commit/37274707f6f3868fae7e0055d9a703006fc142d0 https://github.com/qemu/qemu/commit/684750ab4f8a3ad69512b71532408be3ac2547d4 My concern with this patch is that I haven't seen this come up with utils/dump.py which also uses QemuMonitor's run_monitor. If it is occuring, this should fix issues there as well (From OE-Core rev: 9665d38ab60c1c3b27887c2b1a6396f13a1b33ea) Signed-off-by: Eilís 'pidge' Ní Fhlannagáin Signed-off-by: Richard Purdie

oeqa/qemurunner: Handle rare shutdown race

2024-01-30T15:15:54+00:00

The pid file can disappear when qemu is shutting down leading to a file not found race before it is read. Tweak the code to handle this and fix a rare but annoying race error case. [YOCTO #15036] (From OE-Core rev: 8c07aac9d55f92fe5fbe3cab9f006efecf266328) Signed-off-by: Richard Purdie

qemurunner: more cleanups for output blocking

2023-12-21T10:38:30+00:00

If we are only tracking stdout and are not using self.readsock we end up throwing an exception blocking further action from the thread. Fix this by checking self.readsock is not None first. While we are at it split even into fd, event to make things clearer and handle the fail path of stringify_event by echoing the hex value of the unknown flag.

qemurunner: Improve handling of serial port output blocking

2023-12-20T07:47:00+00:00

Similar to stdout in the previous commit, we need to ensure serial output if written is read and put somewhere, else qemu might block on writes to the serial port leading to hangs in the kernel. Use our existing logging thread to log data when run_serial is not in use. (From OE-Core rev: 05761282ba31e4ba3594f7321e2162d01fe12a5f) Signed-off-by: Richard Purdie

qemurunner: Improve stdout logging handling

2023-12-20T07:47:00+00:00

We need to ensure we read from and log the output from qemu stdout as otherwise the buffers can fill and block, leading qemu to hang. Use our existing logging thread to do this. Reviewed-by: Alex Bennée (From OE-Core rev: a9c46ee014ef1e6436b39fdd4fd15d15388ea795) Signed-off-by: Richard Purdie
