From 2bc9229ea7195b307222bad6de966ea4a27a3f6b Mon Sep 17 00:00:00 2001 From: Ali Saidi Date: Wed, 12 Jul 2006 20:22:07 -0400 Subject: memory mode information now contained in system object States are now running, draining, or drained. memory state information moved into system object system parameter is not fs only for cpus Implement drain() support in devices Update for drain() call that returns number of times drain_event->process() will be called Break O3 CPU!
