scritps/runqemu: Ensure we only have two serial ports

2025-02-24T15:00:53+00:00

I have a theory that some of the console boot issues we're seeing are due to starting images with three serial ports yet only starting gettys on two of them. This means that occasionally, depending on the port numbering we may not get a login prompt on the console we expect it on. To fix this, change the runqemu code so that if serial ports are passed in on the commandline (as is the case in automated testing), we don't add any other GUI serial consoles. We do need to make sure we do have at least two serial ports since we don't want getty timeout warnings.

runqemu: keep generating tap devices

2024-09-27T12:57:35+00:00

in case there is no tap device the script tries to generate a new one. The new device is then unguarded for a moment, so the newly generated device could be acquired by a different instance or user, before it is locked to the instance with acquire_taplock. To fix that keep generating new tap devices in case the lock can't be acquired up to 5 times. If no tap device can be locked it fails in the existing error handling (From OE-Core rev: 23876576d054ebbab9b02c0012782aa56feda123) (From OE-Core rev: 5215635442949a62f502e839ddf1f12e790e5e37) Signed-off-by: Konrad Weihmann Signed-off-by: Richard Purdie Signed-off-by: Steve Sakoman

runqemu: add qmp socket support

Add support for qmp sockets and defaults to unix:qmp.sock if unspecified (From OE-Core rev: 31de620e9d899b93c6e982d3a563bbf618ce79c6) Signed-off-by: Ross Burton Signed-off-by: Eilís 'pidge' Ní Fhlannagáin Signed-off-by: Richard Purdie Backported from master: 380631797f0d63124a8c21efa93ab672dbd79283 Qemu throws many warnings without qmp and many runtime tests fail without this patch also on kirkstone.

scripts/runqemu: fix regex escape sequences

2024-03-01T15:19:53+00:00

When invoking runqemu with Python 3.12, the following warning is encountered: |SyntaxWarning: invalid escape sequence '\.' This is because the interpreter scans the string before it is processed by the regex module, and it interprets the backslash as part of an escape sequence, but not a standard one. This will be registered as an error rather than a warning in future Python versions. To avoid the it, simply add an extra backslash so that Python doesn't misinterpret the string, while the regex parser still sees an escaped '.' character.

runqemu: direct mesa to use its own drivers, rather than ones provided by host distro

2024-02-28T13:32:09+00:00

With mesa 23.0, it is not longer possible to use the host drivers, as mesa upstream has added strict checks for matching builds between drivers and libraries that load them. Add a check and a hint to runqemu so that there is a helpful error when there is no native/nativesdk opengl/virgl support.

scripts/runqemu: allocate unfsd ports in a way that doesn't race or clash with unrelated processes

2023-07-12T15:11:38+00:00

There is already a neat check_free_port() function for finding an available port atomically, so use that and make two additional tweaks: - no need to allocate two separate ports; per unfsd documentation they can be the same - move lockfile release until after unfsd has been shut down and the port(s) used has been freed [YOCTO #15077] (From OE-Core rev: 343510b33650c88367f95e8d8322fae92ae901ca) Signed-off-by: Alexander Kanavin Signed-off-by: Richard Purdie (cherry picked from commit dee96e82fb04ea99ecd6c25513c7bd368df3bd37) Signed-off-by: Steve Sakoman

qemu doesn't always behave well and can hang too. kill it with force if it was still alive. Move clean up commands into cleanup() function.

runqemu: Fix gl-es argument from causing other arguments to be ignored

The code to parse arguments was inadvertently skipping all arguments in the elif block after gl-es if it was specified on the command line.

runqemu: Do not perturb script environment

2022-11-09T17:42:08+00:00

Instead of changing the script environment to affect the child processes, make a copy of the environment with modifications and pass that to subprocess. Specifically, when dri rendering is enabled, LD_PRELOAD was being passed to all processes created by the script which resulted in other commands (e.g. stty) exiting with a failure like: /bin/sh: symbol lookup error: sysroots-uninative/x86_64-linux/lib/librt.so.1: undefined symbol: __libc_unwind_link_get, version GLIBC_PRIVATE Making a copy of the environment fixes this because the LD_PRELOAD is now only passed to qemu itself.
