Review request for Default. Description ------- Changeset 9335:c0639bb5beaa --------------------------- sim: Add drain methods to request additional cleanup operations This patch adds the following two methods to the Drainable base class: memWriteback() - Write back all dirty cache lines to memory using functional accesses. memInvalidate() - Invalidate memory system buffers. Dirty data won't be written back. Specifying calling memWriteback() after draining will allow us to checkpoint systems with caches. memInvalidate() can be used to drop memory system buffers in preparation for switching to an accelerated CPU model that bypasses the gem5 memory system (e.g., hardware virtualized CPUs). Note: This patch only adds the methods to Drainable, the code for flushing the TLB and the cache is committed separately.
