From a26f7358583174f2fe0df3e979f7b8b02069278c Mon Sep 17 00:00:00 2001 From: Toomas Soome Date: Tue, 9 Feb 2021 00:34:47 +0200 Subject: [PATCH] loader: do not autoselect smaller font than 8x16 with high res display The VT screen buffer size is calculated based on our default built in (8x16) font. With high-resolution display, we want to use at least 8x16 font, or we will have large unused areas on screen.
