The branch main has been updated by dumbbell: URL: https://cgit.FreeBSD.org/src/commit/?id=40c20fc29cad4d38d9a565e9c7ba78612097308e commit 40c20fc29cad4d38d9a565e9c7ba78612097308e Author: Jean-Sébastien Pédron <dumbbell@FreeBSD.org> AuthorDate: 2023-11-29 18:34:48 +0000 Commit: Jean-Sébastien Pédron <dumbbell@FreeBSD.org> CommitDate: 2023-11-29 18:54:14 +0000 vt(4): Call post-switch callback after replacing the backend [Why] For instance, it gives a chance to the new backend to refresh the screen. This is needed by the vt_drmfb backend and `drm_fb_helper`. This change was lost when I posted changes to reviews.freebsd.org and it broken the amdgpu driver... Thanks to manu@ for reporting the problem and wulf@ to find out the missing change!
