I tripped across a situation where one of my Qt5 applications that used a periodic QTimer stops receiving timeout signals after 1 hour 10 minutes of normal operation.
(This is in Genode 18.08, x86_32 and x86_64, nova and seL4.) The same application keeps on ticking (for many hours at least) when compiled and run under Linux. A Qt Forum participant speculates "a 2^32 wraparound? Because 4294967296 (2^32) microseconds is 4295 seconds." This is just about the observed time. The Qt5 documentation suggests that some Qt timers on some platforms can have this problem--it depends on the underlying clock source. Can anyone comment on the relevant clock source for QTimer in the Genode port? For reference, a native Genode Timer connection does not exhibit this problem, so using it in this application was a viable workaround. // Steve _______________________________________________ Genode users mailing list [email protected] https://lists.genode.org/listinfo/users
