Review request for Default. Repository: gem5 Description ------- Changeset 10621:f5c7429fbbde --------------------------- config: Expose the DRAM ranks as a command-line option This patch gives the user direct influence over the number of DRAM ranks to make it easier to tune the memory density without affecting the bandwidth (previously the only means of scaling the device count was through the number of channels). The patch also adds some basic sanity checks to ensure that the number of ranks is a power of two (since we rely on bit slices in the address decoding).
