(Updated Aug. 7, 2013, 5:21 p.m.) Review request for Default. Repository: gem5 Description (updated) ------- Changeset 9831:b5aed07974d4 --------------------------- mem: Perform write merging in the DRAM write queue This patch implements basic write merging in the DRAM to avoid redundant bursts. When a new access is added to the queue it is compared against the existing entries, and if it is either intersecting or immediately succeeding/preceeding an existing item it is merged. There is currently no attempt made at avoiding iterating over the existing items in determining whether merging is possible or not. Diffs (updated) ----- src/mem/simple_dram.hh 2492d7ccda7e src/mem/simple_dram.cc 2492d7ccda7e Diff: http://reviews.gem5.org/r/1962/diff/ Testing ------- With the Alpha quiesce patch and stats updates all regressions pass.
