How do you determine the minimum timer resolution for a timerfd+EPOLL timer solution?
Clash Royale CLAN TAG#URR8PPP
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty margin-bottom:0;
I am using timerfd_create
/timerfd_settime
/EPOLL
to create timers in my application. According to the EPOLL
documentation if a timer is set fire at a point lower than the minimum resolution, it will instead fire at the next tick.
What I cannot find is how the minimum timer resolution is determined. What system settings and/or timerfd
/EPOLL
options control this?
