From: Jeremy Linton on gitlab.com https://gitlab.com/cki-project/kernel-ark/-/merge_requests/3460#note_2229168436 So, its not possible to turn this on with PPC at the moment without upstream kernel changes. S390x is a different story, and the zstd builds do work (at least in qemu), but when tracking back the commit which enables it there was a comment that they are slower on real HW (z15+) because its providing a hardware zlib decompressor. So, it is a case of slower decompression to save a few percent disk space, which I guess probably isn't a good tradeoff on that platform. -- _______________________________________________ kernel mailing list -- kernel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to kernel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/kernel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
