From cbac507d93dc357a75ccc11fdda5c7ed60935538 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Sun, 13 Jul 2025 15:18:53 +0100 Subject: [PATCH 1/1] re-try EDID reading when it fails some video converters are a bit buggy and have to be probed twice; linux works fine, but in these cases, coreboot won't set up the display. try it twice, to mitigate, when probing the EDID This entire function should probably be rewritten, since it's buggy in general.
