EDAC: Add missing MEM_LRDDR4 entry in edac_mem_types[]

2018-08-24T11:04:48Z

commit b748f2de4b2f578599f46c6000683a8da755bf68 upstream. The edac_mem_types[] array misses a MEM_LRDDR4 entry, which leads to NULL pointer dereference when accessed via sysfs or such.

EDAC: Add new memory type for non-volatile DIMMs

2018-03-14T11:32:06Z

There are now non-volatile versions of DIMMs. Add a new entry to "enum mem_type" and a new string in edac_mem_types[]. Signed-off-by: Tony Luck Cc: "Rafael J.

EDAC: Drop duplicated array of strings for memory type names

2018-03-14T11:20:16Z

Somehow we ended up with two separate arrays of strings to describe the "enum mem_type" values. In edac_mc.c we have an exported list edac_mem_types[] that is used by a couple of drivers in debug messaged. In edac_mc_sysfs.c we have a private list that is used to display values in: /sys/devices/system/edac/mc/mc*/dimm*/dimm_mem_type /sys/devices/system/edac/mc/mc*/csrow*/mem_type This list was missing a value for MEM_LRDDR3. The string values in the two lists were different :-( Combining the lists, I kept the values so that the sysfs output will be unchanged as some scripts may depend on that.

EDAC: Add helper which returns the loaded platform driver

2017-09-25T10:55:59Z

Only a single EDAC platform driver can be loaded. When ghes_edac is enabled, an EDAC platform driver still attempts to register itself and fails in edac_mc_add_mc(). Add edac_get_owner() so that EDAC platform drivers can check the owner first.
