Ah ok. I had a sneaking suspicion that perhaps this was the case but it wasn't obvious to me even after five read-throughs of the documentation :) > > What you are seeing likely stems from your BSP definition. How have to > defined it for your board ? This is where my confusion lies. I defined my BSP as follows, trying to follow the 'beaglebone' examples from the documentation. I don't want to include ktypes/preempt-rt because it enables a bunch of *_DEBUG kernel configuration options as well as other stuff that I find bloat-y. --- define KMACHINE rk3588-firefly-itx define KTYPE preempt-rt define KARCH arm64 include ktypes/tiny branch firefly-preempt-rt kconf non-hardware firefly-preempt-rt.cfg include remove-non-rockchip-arch-arm64.ssc --- Then in my machine .conf I add this line (without this I'm not sure how to tell yocto to use the bsp definition I created): KERNEL_FEATURES += " bsp/rockchip/firefly-preempt-rt.scc" > > The tools know that with a proper BSP definition that they don't need to > re-apply patches, since they are already in the trees and only the kernel > type configuration will be used. > > In this case, everything in the standard kernel and preempt-rt kernel are > already on the v6.6/standard/preempt-rt/base branch, so they'll be skipped. > Only your BSP patches and configuration will be added. > > But that functionality needs a proper BSP definition to work. > > If you find the section "recipe space BSPs" in the project documentation, it > has more details. > > Bruce > >
