The "virgin" -rt patch from kernel.org doesn't apply cleanly. First off there is a slight version mismatch and secondly this is the raspberrypi kernel, not a pure upstream kernel. Is there a way to patch a patch before it gets applied? If it could be fetched from kernel.org then patched before applying that would be ideal! The diff isn't that big; it's sad to have to provide a >1MB patch for such a small tweak. I guess that's why the yocto kernels/patches have their own repositories on yoctoproject.org? -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
