OK. It took a while to get kernel 5.3.7 building aginst libopencsd0.12, but it is now, so I could test this. The debian kernel package does indeed now need a small patch to enable coresight in perf. Attached. (and this bug re-assigned to the kernel). Wookey -- Principal hats: Linaro, Debian, Wookware, ARM http://wookware.org/
