| Series | [oe,meta-oe,v2] bpftool: add new recipe | expand |
This recipe only works for kernels > 4.14-ish. Some BSP layers aren't there yet (e.g. meta-qcom, meta-raspberrypi) Is there an elegant way to handle this situation? -- _______________________________________________ Openembedded-devel mailing list Openembedded-devel@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-devel

I'm not sure what I'd use as the package. linux? linux-image? I've tried a bunch of variations on the following incantation, but nothing seems to trigger (testing specifically with rpi): RDEPENDS_${PN} = "kernel-image-zimage (>= 4.15)" -- _______________________________________________ Openembedded-devel mailing list Openembedded-devel@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-devel

The bpftool allows for inspection and simple manipulation of eBPF programs and maps, so common in the kernel selftests.
