My approach on the tracers/rtla is to make the simple things in kernel, and beautify things in user-space. You could keep the tracepoint as a mask, and then make it pretty, like cpus=3-5,8 in user-space. For example with a trace-cmd/perf loadable plugin, libtracefs helper. For rtla I was thinking to make a new tool to parse them. and make it pretty there. -- Daniel _______________________________________________ linux-snps-arc mailing list linux-snps-arc@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-snps-arc
