From b9581d677d4a5d21635038e3abaa3cc0fc31a2ea Mon Sep 17 00:00:00 2001 From: Jon Mason Date: Wed, 1 Oct 2025 13:57:01 -0400 Subject: [PATCH] runqemu: remove setting of mem on kernel command line for certain systems Some emulated hardware will not boot if mem is set on the kernel command line (all of the Raspberry Pi machines seemed to fail with this set, possibly many others). Also, it is not necessary if the device tree file is present, as that _should_ have the memory size specified in it. Add a check for QB_DTB and don't set mem in the kernel command line if present.
