You just need to know how to break the name down: 1) 'linux-yocto' is what will be built; 2) when the MACHINE is 'qemux86'. So, PREFERRED_VERSION_linux-yocto_qemux86 ?= "3.0%" says that the 'linux-yocto_3.0x' kernel recipe (look in meta/recipes-kernel/linux) is the preferred kernel to build for the 'qemux86' machine. bitbake knows how to extract the parts that follow PREFERRED_VERSION (and similar), so you won't find direct references to PREFERRED_VERSION_linux-yocto_qemux86. I'm sure someone will be along to explain that better shortly... Chris Tapp opensou...@keylevel.com www.keylevel.com
