You seem to be working on the assumption that the Debian config is related to upstream defconfig files. This is not the case - the upstream defaults we start from are those in the Kconfig files. Currently we don't explicitly set CONFIG_FB for arm64, and the only reason it's enabled as a module is that the DRM drivers (which are built as modules) select it. We *do* explicitly set CONFIG_FB=y on almost all other architectures and flavours, one by one. I'm going to simplify this by setting CONFIG_FB=y at the top level and overriding in a few cases, not including arm64. > Since CONFIG_FB_EFI is "depends on > (FB = y)", this means we don't get efifb support on arm64.

So what you're actually requesting is to enable CONFIG_FB_EFI on arm64 and armhf. I'll do that too. Ben. -- Ben Hutchings Never put off till tomorrow what you can avoid all together.
