From 7bc3eaec7a7a67b821774bea4298418241cbf815 Mon Sep 17 00:00:00 2001 From: Andreas Hansson Date: Mon, 19 Aug 2013 03:52:26 -0400 Subject: [PATCH] mem: Allow disabling of tXAW through a 0 activation limit This patch fixes an issue where an activation limit of 0 was not allowed. With this patch, setting the limit to 0 simply disables the tXAW constraint. --- src/mem/simple_dram.cc | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/src/mem/simple_dram.cc b/src/mem/simple_dram.cc index 2bb1cec9d..3d8f71ee9 100644 --- a/src/mem/simple_dram.cc +++ b/src/mem/simple_dram.cc @@ -852,6 +852,10 @@ SimpleDRAM::recordActivate(Tick act_tick) DPRINTF(DRAM, "Activate at tick %d\n", act_tick); + // if the activation limit is disabled then we are done + if (actTicks.empty()) + return; + // sanity check if (actTicks.back() && (act_tick - actTicks.back()) < tXAW) { panic("Got %d activates in window %d (%d - %d) which is smaller " -- 2.30.2
