Hi We started testing with recording the call, will Update on icount Enable icount to be "enabled" independently of tcg. icount + ttcg breaks, so there needs to be done some changes here. The plugin allows to plug into the timer subsystem, so all the times are available. Having multithread ttcg makes things complicated. We don't want three versions of icount: - deterministic - multithread - .... The plugin only allows some primitives to handle the times, not the full power of TCG. We will try to break out the icount generation without disturbing determinism. The plugin will be able to calculate the time, and everything else will read it from there. The current code will continue to be as it is, and will not work with multithread ttcg. We got a recording of the call here: https://fileserver.linaro.org/s/nJTSCLyQBfo6GLJ Thanks to Alex for storing it. Later, Juan.
