Thisprevents the test from being reported as a true failure in environmentswhere scheduling latency is high enough to delay timerfd wakeups.Fixes: cb692380f1e0 ("timerfd: Expect periodic timer ...")MFC after: 1 week List of files: /src/tests/sys/kern/timerfd.c Thu, 26 Mar 2026 16:40:17 +0000 Jake Freeland <jfree@FreeBSD.org> http://opengrok.net:8080/history/src/tests/sys/kern/timerfd.c#cb692380f1e05ffc4184877844e93051f24ed302 timerfd: Expect periodic timer performance failuresThe current timerfd implementation fails to correctly count events on ananosecond callout interval. The timerfd__periodic_timer_performancetest detects this and reports failure.Mark this test as an expected failure so it isn't flagged by CI. A linkto the bug report is attached to the test for reference.While we're here, clean up some minor style and Make issues.Fixes: 834c1ba793d9 ("timerfd: Add tests")MFC after: 1 week List of files: /src/tests/sys/kern/timerfd.c Wed, 25 Mar 2026 22:57:16 +0000 Jake Freeland <jfree@FreeBSD.org> http://opengrok.net:8080/history/src/tests/sys/kern/timerfd.c#85c0f1a87da1fd1eb3e646e86f70e630c48da91a timerfd: Fix interval callout schedulingWhen a timerfd interval callout misses its scheduled activation time, adifferential is calculated based on the actual activation time and thescheduled activation time. This differential is divided by the timerfd'sinterval time and the quotient is added to the timerfd's counter.Before this change, the next callout was scheduled to activate at:scheduled activation time + timerfd interval.This change fixes the scheduling of the next callout to activate at:actual activation time + timerfd interval - remainder.Reviewed by: markjDifferential Revision: https://reviews.freebsd.org/D55790MFC after: 2 weeks List of files: /src/tests/sys/kern/timerfd.c Fri, 20 Mar 2026 06:33:03 +0000 Jake Freeland <jfree@FreeBSD.org> http://opengrok.net:8080/history/src/tests/sys/kern/timerfd.c#834c1ba793d900b791e19ff449b1e0b96fb494a0 timerfd: Add testsTake Jan Kokemuller's timerfd tests from the epoll-shim project,stripping out code that isn't directly related to FreeBSD.Reviewed by: markjDifferential Revision: https://reviews.freebsd.org/D55789MFC after: 2 weeks List of files: /src/tests/sys/kern/timerfd.c Fri, 20 Mar 2026 06:31:30 +0000 Jake Freeland <jfree@FreeBSD.org>
