Description: (RO) Memory repair function type. For e.g. post package repair, memory sparing etc. Valid values are: - ppr - post package repair. Please define its mode via /sys/bus/edac/devices/<dev-name>/mem_repairX/persist_mode - cacheline-sparing - Cacheline memory sparing - row-sparing - Row memory sparing - bank-sparing - Bank memory sparing - rank-sparing - Rank memory sparing - All other values are reserved. and define persist_mode in a different way: What: /sys/bus/edac/devices/<dev-name>/mem_repairX/ppr_persist_mode ... Description: (RW) Read/Write the current persist repair (PPR) mode set for a post package repair function. Persist repair modes supported in the device, based on the memory repair function is temporary or permanent and is lost with a power cycle. Valid values are: - repair-soft - Soft PPR function (temporary repair). - repair-hard - Hard memory repair function (permanent repair). - All other values are reserved. Thanks, Mauro
