From a15f77e3361d5baeb7500e75d749b92f0d1e9e0e Mon Sep 17 00:00:00 2001 From: Jonathon Hall Date: Fri, 9 Feb 2024 15:20:50 -0500 Subject: [PATCH] config/coreboot-librem_11.config: intel_iommu=igfx_off on Heads cmdline intel_iommu=igfx_off is needed on the Heads kernel command line for memtest86+ to work. Without this parameter, the screen blanks when memtest86+ starts testing. This is unique to Librem 11, probably because it is the only device using FSP GOP for graphics init in coreboot. (libgfxinit does not yet support Jasper Lake.)
