Sorry, I messed up my numbering there. That note was meant for the qed/ directory, not mediatek/ . I've been working on this this morning. I'm pretty sure we can just drop every file but one in qed/ - it contains a lot of old versions that we don't need to care about any more. We can lose some stuff from mediatek/ - not any of the wifi stuff, but there's some firmware in there for ARM SoCs we do not even build the drivers for. I found a few other little cleanups, too. I *think* we can fairly safely drop about 31M of iwlwifi firmwares from linux-firmware, I'm testing a PR for that right now. We could potentially drop even more in lorax (since we don't really need to support booting the current installer with an older kernel - that's a constraint on dropping things from the linux-firmware package too soon, as it would be a bit mean to break things for people booting older kernels on installed systems for some reason). -- Adam Williamson Fedora QA IRC: adamw | Twitter: adamw_ha https://www.happyassassin.net _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-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/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
