The branch main has been updated by tsoome: URL: https://cgit.FreeBSD.org/src/commit/?id=3630506b9daec9167a89bc4525638ea45a00769e commit 3630506b9daec9167a89bc4525638ea45a00769e Author: Toomas Soome <tsoome@FreeBSD.org> AuthorDate: 2020-12-21 05:31:16 +0000 Commit: Toomas Soome <tsoome@FreeBSD.org> CommitDate: 2021-01-02 19:41:36 +0000 loader: implement framebuffer console Draw console on efi. Add vbe framebuffer for BIOS loader (vbe off, vbe on, vbe list, vbe set xxx). autoload font (/boot/fonts) based on resolution and font size. Add command loadfont (set font by file) and variable screen.font (set font by size). Pass loaded font to kernel. Export variables: screen.height screen.width screen.depth Add gfx primitives to draw the screen and put png image on the screen. Rework menu draw to iterate list of consoles to enamble device specific output. Probably something else I forgot...
