Package: linux-perf-4.16 Version: 4.16~rc6-1~exp1 Severity: wishlist Tags: patch
In kernel 4.16 perf has support for libopencsd, which decodes arm coresight trace packets. This should be enabled in debian kernels so that it 'just works' for users. perf compilation picks up libopencsd if it installed so enabling it is simply a matter of adding it to the build-dependencies so that it is available at build time. Attached is a patch that does this. However note that, whilst libopencsd is now packaged for debian it has not yet been uploaded to the archive (one build issue remains to be fixed before it can be uploaded), and clearly this build-dep can't be added until the library is actually available. So this bug is blocked on #891955
