Starting with kernel version 6.4 libtraceevent is removed from the kernel sources and perf depends of an externally provided libtraceevent unless explicitely opted out. perf.bb with this patch will fail when built with a 6.4 kernel. I guess as an interim solution building perf on 6.4 without traceevent would fix the SDK issue you see with older kernels. I could then try out how to build perf with an external libtraceevent also for older kernels (LIBTRACEEVENT_DYNAMIC) so that it would work for all kernel/perf versions.
