From 8a354bd935a800dd2d98ac8f30707e2912c80ae6 Mon Sep 17 00:00:00 2001 From: Pavel Dovgalyuk Date: Thu, 17 Sep 2015 19:24:56 +0300 Subject: replay: ptimer This patch adds deterministic replay for hardware periodic countdown timers. ptimer uses bottom halves layer to execute such an asynchronous callback. We put this callback into the replay queue instead of bottom halves one. When checkpoint is met by main loop thread, the replay queue is processed and callback is executed. Binding callback moment to one of the checkpoints makes it deterministic.
