qemurunner: Clean up serial_lock handling

2024-11-26T13:37:09+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.

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

oeqa/qemurunner: Drop newlines serial workaround

Drop the newlines serial workaround, it doesn't seem to fix things enough of the time to be useful. (From OE-Core rev: 6cd57b2d148c5de7839d52d8cec359e4a10e0cd6) Signed-off-by: Richard Purdie

oeqa/qemurunner: Ensure we retry after BrokenPipeError

2023-10-11T08:39:46+00:00

If the BrokenPipeError occurs when writing to the serial port to wake it up, defer the write and try again (which will happen on the 5s timeout of the select call). Why it should return ESHUTDOWN and then work later I'm not sure but it does appear to make it work. For now we need 'working' QA tests whilst the issue is debugged.

oeqa/qemurunner: Add extra logging when console doesn't appear

2023-10-10T08:53:32+00:00

If the console doesn't appear, breifly sleep and try an extra read. This is a useful debugging trick which we may as well preserve in the code. We're already failing at this point so extra data is useful. This means if we perturb things on the other port, we may gain useful logging insight.
