The hard problem is that at panic time you have no idea what state the system is in. So ideally you bring the message to the screen without taking any locks, to avoid being stopped by a deadlock. A generic solution which goes through drm interfaces (like generic fbdev emulation does) simply can't do that. take care, Gerd -- _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org 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@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
