Because we only match the active kernels in oe-core. That's 5.4. You must use the older branches to get older kernels. > [ linux-yocto_5.4_virtualization.inc ] => [linux-yocto_virtualization.inc] > => [KERNEL_FEATURES_append = " cfg/virtio.scc" ]=> [error "cfg/virtio.scc" ] > > b) Looking for the file , i found the required file at > http://git.yoctoproject.org/cgit/cgit.cgi/yocto-kernel-cache/tree/cfg > But now , i am not sure where is the "cfg" folder where i can store the > file as per KERNEL_FEATURES_append = " cfg/virtio.scc" You must use the kernel-cache for those fragments, that's the design of KERNEL_FEATURES. It looks at the centralized fragment repository. If you are providing something in your own layer, or using your own kernel recipe, you must have a fragment of that name, in that directory structure. I've just recently explained this in detail in: https://bugzilla.yoctoproject.org/show_bug.cgi?id=13927 Cheers, Bruce > > Can team members please provide any debugging info or let me know if i am > missing something completely here. > > Thanks , > Ashish > > > > > > > > > > > > > > > > > -- - Thou shalt not follow the NULL pointer, for chaos and madness await thee at its end - "Use the force Harry" - Gandalf, Star Trek II
