From b204f62b5a625f8ebf809ce69067a77ba6b4dfd9 Mon Sep 17 00:00:00 2001 From: Punit Agrawal Date: Sat, 23 May 2020 00:44:15 +0900 Subject: [PATCH] x86: grub-efi: Enable serial console When running the installer images on x86 platform with EFI firmware, there is no output on the serial console. This is a problem on headless servers or "-nographic" VM that do not have a display attached. Let's make it easier for more of our users to be able to install debian by also enabling output on serial console. -- Changes since v1: * Simplified the patch to focus on serial enablement * Setup serial port and terminal_input * Use "--append" with terminal_output (and terminal_input) --- build/boot/x86/grub/grub-efi.cfg | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/build/boot/x86/grub/grub-efi.cfg b/build/boot/x86/grub/grub-efi.cfg index c49274aa8..20ce37648 100644 --- a/build/boot/x86/grub/grub-efi.cfg +++ b/build/boot/x86/grub/grub-efi.cfg @@ -21,5 +21,10 @@ else set menu_color_highlight=white/blue fi +# Setup the serial port +serial --unit=0 --speed=9600 +terminal_input --append serial +terminal_output --append serial + insmod play play 960 440 1 0 4 440 1 -- 2.26.0
