Hi Pratik,

Thanks for adding tests. It looks like some of these are failing on the
autobuilder:

Failed ptests:
{'zstd': ['compression/window-resize.sh',
          'compression/window-resize.sh.check_stdout',
          'cli-tests']}

https://autobuilder.yoctoproject.org/valkyrie/#/builders/73/builds/4443

Test outputs can be found here:
https://valkyrie.yocto.io/pub/non-release/20260831-42/testresults/qemux86-64-ptest/core-image-ptest-zstd/

Can you have a look at the issue?

Thanks,
Mathieu
