Sorry for inconvenience. I have sent a patch to allow the build to report error when detect feature failure for libopencsd [1]. It's obviously that there have another issue with 'make -C tools/perf build-test' which should not build with option 'CORESIGHT=1' by default. Please let me know if you want me to follow this issue or not. Thanks, Leo [1] https://lists.linaro.org/pipermail/coresight/2021-September/006967.html p.s. I didn't use the patch linkage from lore.kernel.org, seems the server is down when I try to fetch link from it. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
