From c03fa428ac6e439afa1d437776365a632ce24262 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Thu, 20 Oct 2022 23:27:02 -0400 Subject: [PATCH] arm64: defconfig: build-in Qualcomm SC7180 and SM8450 interconnects On Qualcomm SC7180 and SM8450 SocS, the typical debug console serial port is part of GENI Serial Engine QUP Wrapper Controller which uses interconnects. This means that without interconnect drivers, the serial might not probe. Without serial console, the root might not be mounted by initramfs: + REASON=No init found. Try passing init= bootarg. PS1=(initramfs ... (initramfs) run-init -c /dev/console -n /root /sbin/init run-init: opening console: No such file or directory This means that interconnect drivers on these Qualcomm SoCs cannot be modules and must be built-in to mount rootfs.
