Add tracepoints to retrieve information about the invoke_fn. This would help to measure how many invoke_fn are triggered and how long it takes to complete one invoke_fn call.

I think it affects everything. The problem is that the drivers/tee/optee/Makefile needs to be updated with: CFLAGS_call.o := -I$(src) otherwise the compiler wont know how to find the path to optee_tree.h. This is described in: samples/trace_events/Makefile -- Steve _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
