Does REMOVE_SINGLE_CYCLE_DCACHE_FAST_PATH has to be set to  true for all CMP protocols

No, at least MOESI_CMP_directory do not need it to be true.

Hi,

Does REMOVE_SINGLE_CYCLE_DCACHE_FAST_PATH has to be set to  true for all CMP protocols i.e. 1.MESI_CMP_directory 2.MSI_MOSI_CMP_directory3.MOESI_CMP_directory. If yes why? and if it is set to true then I can't see the L1 cache stats.

Thanks,
Lopamudra
