The edac_mc_alloc() routine allocates one dimm_info device for all possible memories, including the non-filled ones. The debug messages there are somewhat confusing. So, cleans them, by moving the code that prints the memory location to edac_mc, and using it on both edac_mc_sysfs and edac_mc. Also, only dumps information when DIMM/ranks are actually filled. After this patch, a dimm-based memory controller will print the debug info as: [ 1011.380027] EDAC DEBUG: edac_mc_dump_csrow: csrow->csrow_idx = 0 [ 1011.380029] EDAC DEBUG: edac_mc_dump_csrow: csrow = ffff8801169be000 [ 1011.380031] EDAC DEBUG: edac_mc_dump_csrow: csrow->first_page = 0x0 [ 1011.380032] EDAC DEBUG: edac_mc_dump_csrow: csrow->last_page = 0x0 [ 1011.380034] EDAC DEBUG: edac_mc_dump_csrow: csrow->page_mask = 0x0 [ 1011.380035] EDAC DEBUG: edac_mc_dump_csrow: csrow->nr_channels = 3 [ 1011.380037] EDAC DEBUG: edac_mc_dump_csrow: csrow->channels = ffff8801149c2840 [ 1011.380039] EDAC DEBUG: edac_mc_dump_csrow: csrow->mci = ffff880117426000 [ 1011.380041] EDAC DEBUG: edac_mc_dump_channel: channel->chan_idx = 0 [ 1011.380042] EDAC DEBUG: edac_mc_dump_channel: channel = ffff8801149c2860 [ 1011.380044] EDAC DEBUG: edac_mc_dump_channel: channel->csrow = ffff8801169be000 [ 1011.380046] EDAC DEBUG: edac_mc_dump_channel: channel->dimm = ffff88010fe90400 ...
