runqemu: fix special characters bug

2025-09-22T20:17:52+00:00

Fix the bug in runqemu that happens when the file path contains the specific words such as 'vmlinux', e.g. /home/frank/vmlinux. runqemu - ERROR - wic doesn't need kernel (From OE-Core rev: 0276bd0e8d5cefb6f98d685bc9faa0451780bef9) Signed-off-by: Libo Chen Signed-off-by: Richard Purdie (cherry picked from commit 3c186fe7741adecb0887e36c8a9164a58fc16437) Signed-off-by: Steve Sakoman

runqemu: Fix detection of -serial parameter

2024-10-18T13:04:41+00:00

The pattern `-serial` matches also `-device usb-serial` and `virtio-serial` which are not the desired parameter. This causes the serial console ttyS1 is missing and Systemd's getty@ttyS1 fails constantly.

runqemu: keep generating tap devices

2024-10-02T13:15:15+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: ae4e4fb703f63402cacbef772e70082e5760f78a) Signed-off-by: Konrad Weihmann Signed-off-by: Richard Purdie (cherry picked from commit 23876576d054ebbab9b02c0012782aa56feda123) Signed-off-by: Steve Sakoman

runqemu: match .rootfs. in addition to -image- for rootfs

2024-01-04T23:47:51+00:00

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 (From OE-Core rev: 107d0db3dc3678e6f0ae4035f4c0b86c6b421168) Signed-off-by: Mikko Rapeli Signed-off-by: Richard Purdie

scripts/runqemu: fix regex escape sequences

2024-01-02T22:51:01+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: Add squashfs filesystem types

2023-10-23T09:49:19+00:00

When using a squashfs filesystem type, runqemu requires specifying the full path to the image because it doesn't list squashfs types in its fstypes variable. Add them to provide the same support as other filesystem types.

runqemu/qemurunner: Use nodelay with tcp serial connections

This disables Nagle's algorithm for our tcp serial connections which may be causing data transfer issues. (From OE-Core rev: f8eff4c427881a98333fdf7c42f66ed6603e4f03) Signed-off-by: Richard Purdie

scritps/runqemu: Ensure we only have two serial ports

2023-10-04T12:00:33+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. (From OE-Core rev: 1b0348535dce3b776efbcf26406b94730a51eb85) Signed-off-by: Richard Purdie

runqemu: check permissions of available render nodes as well as their presence

2023-09-09T11:04:55+00:00

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.
