2024-01-04runqemu: match .rootfs. in addition to -image- for rootfsMikko Rapeli
Also change path.exists() and !path.isdir() to a single path.isfile() which should be equal. Enables running tests against image recipes which are not called "bla-image" but plain "bla". Currently they fail with do_testimage/runqemu error: runqemu - ERROR - Unknown path arg /home/builder/src/base/build/tmp_qemuarm64/deploy/images/qemuarm64/img-qemuarm64.rootfs.wic Suggested-by: Richard Purdie <richard.purdie@linuxfoundation.org> Signed-off-by: Mikko Rapeli <mikko.rapeli@linaro.org> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2024-01-02scripts/runqemu: fix regex escape sequencesTrevor Gamblin
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.

2023-10-04scritps/runqemu: Ensure we only have two serial portsRichard Purdie
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. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2023-09-09runqemu: check permissions of available render nodes as well as their presenceAlexander Kanavin
qemu itself is not helpful when render nodes exist, but can't be opened: qemu-system-x86_64: egl: render node init failed To fix this, users likely need to * modprobe vgem (presence when physical graphic card is absent or has a driver without support for render nodes, such as many older cards found in server machines) * add their user to "render" group to write to /dev/dri/renderD* (permissions) With this change runqemu should print hints for the above as appropriate from probing the nodes.

2023-06-28runqemu: Fix automated call to runqemu-ifupAlejandro Hernandez Samaniego
When runqemu tries to call runqemu-ifup to create tap devices, it checks the output of runqemu-ifup to get the newly created tap device. The behavior of runqemu-ifup was recently modified along with its output, it no longer expects the uid parameter to be passed and it prints out a warning if it was, since this warning was now part of the output runqemu tries to parse it and convert it to an int() which proved impossible. Pass the correct arguments to the runqemu-ifup call and echo the warning to stderr instead to make sure its not being parsed and used by runqemu in any case.

Instead of changing the script environment to affect the child processes, make a copy of the environment with modifications and pass that to subprocess.

Running "runqemu qemux86 kvm" when qemu is configured for sdl and/or gtk display output currently leads to a poor user experience with no cursor and corrupted fonts in the gtk case. This is due to no options being passed to qemu which leads to the loss of the font envirornment variable and the show-cursor option. If the user hasn't specified a display type, grep the output of "qemu-system-xxx --help" for the display types and pick the "best" which ensures our config is passed in.

This is particularly useful for llvm-accelerated GL rendering from qemu guest to an offscreen buffer (accessible over vnc or spice) using llvmpipe on the host, rather than using unaccelerated swrast renderer in the guest. This is the best that can be done in the absence of a host GPU with render node support (such as old Matrox cards common in servers, or fully virtualized cloud environments with no GPU at all). Note: even though NVidia blob drivers do support render nodes, they do not support gbm (yet?), and so rendering will fall back to llvmpipe as well even when the system has a 3000 euro NVidia GPU.
