qt5-qtwebengine available
by Dan Horák 04 Oct '22

04 Oct '22

Hi all, thanks to the work the community does on porting the Chromium browser to ppc64le, we can have also the qt5-qtwebengine library available. Currently there are ~20 packages that are excluded on ppc64le due the unavailability of the webengine. My "talos" COPR repository [1] contains now the main qt5-qtwebengine package, pyqtwebengine bindings for Python and also the qmapshack app. Building calibre fails in a test, investigating now. If there are other apps you would like to be made available, let me know. The plan is to merge the ppc64le support into the official Fedora rpms, but it can take some time and depends on support from the maintainers of the QT stack.

SIGILL from openssl-3.0.5-3.fc38 on Power8

Hi, seems the recent update of openssl with a sync from RHEL brought in some incompatibility with Power8 systems leading to non-working dnf or ssh on such systems. I have reported it as https://bugzilla.redhat.com/show_bug.cgi?id=2124845 Dan

kernel-6.0.0-0.rc4.31.fc38.ppc64le broken
by Dan Horák 07 Sep '22

07 Sep '22

Hi all, seems the latest 6.0-rc4 kernel is broken for ppc64le, so be aware. It fails very early with the following on a P8 system, and I guess on P9 like Talos II as well (it fails to boot on Talos for sure, but I haven't captured the traceback yet). Seems a fix already exists in https://lists.ozlabs.org/pipermail/linuxppc-dev/2022-September/247979.html ...
