It seems that without using a realtime kernel, the preempt function improves things. In theory, from version 5.16, this feature improves and becomes "full" (with a lower latency without using a realtime kernel). I am not a specialist and able to produce exotic kernels every other day.
My point is rather to be able to introduce tools to evaluate the improvements beyond : "it's more transparent... it sounds better". In short, is it possible, for those who have a build and extension platform, to compile a version of cyclictest in order to have a latency evaluation tool ? Even if this indicator is not everything (hardware, power supply, buffers, etc. must also be taken into account), it is still correlated with sq. https://wiki.linuxfoundation.org/realtime/documentation/howto/tools/cyclictest/start When will the 5.16 kernel be available in piCorePlayer ? :) And thanks for the work already done. ------------------------------------------------------------------------ zaurux's Profile: http://forums.slimdevices.com/member.php?userid=69135 View this thread: http://forums.slimdevices.com/showthread.php?t=116024 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
