699ea521 - EDAC: Add a memory repair control feature

Wed, 12 Feb 2025 14:36:42 +0000

EDAC: Add a memory repair control featureAdd a generic EDAC memory repair control driver to manage memory repairs inthe system, such as CXL Post Package Repair (PPR) and other soft and hard PPRfeatures.For example, a CXL device with DRAM components that support PPR features mayimplement PPR maintenance operations. DRAM components may support two types ofPPR: - hard PPR, for a permanent row repair, and - soft PPR, for a temporary row repair.Soft PPR is much faster than hard PPR, but the repair is lost with a powercycle.When a CXL device detects an error in a memory, it may report the need fora repair maintenance operation by using an event record where the "maintenanceneeded" flag is set. The event records contain the device physicaladdress (DPA) and other optional attributes of the memory to repair.The kernel will report the corresponding CXL general media or DRAM trace eventto userspace, and userspace tools (e.g. rasdaemon) will initiate a repairoperation in response to the device request via the sysfs repair control.Device with memory repair features registers with EDAC device driver, whichretrieves a memory repair descriptor from EDAC memory repair driver and exposesthe sysfs repair control attributes to userspace in /sys/bus/edac/devices//mem_repairX/.The common memory repair control interface abstracts the control of arbitrarymemory repair functionality into a standardized set of functions. The sysfsmemory repair attribute nodes are only available if the client driver hasimplemented the corresponding attribute callback function and providedoperations to the EDAC device driver during registration.

bcbd069b - EDAC: Add a Error Check Scrub control feature

Wed, 12 Feb 2025 14:36:41 +0000

EDAC: Add a Error Check Scrub control featureAdd an Error Check Scrub (ECS) control to manage a memory device's ECSfeature.The ECS is a feature defined in JEDEC DDR5 SDRAM Specification (JESD79-5) andallows the DRAM to internally read, correct single-bit errors, and write backcorrected data bits to the DRAM array while providing transparency to errorcounts.The DDR5 device contains a number of memory media Field Replaceable Units(FRU) per device. The DDR5 ECS feature and thus the ECS control driversupports configuring the ECS parameters per FRU.Memory devices support the ECS feature register with the EDAC device driver,which retrieves the ECS descriptor from the EDAC ECS driver. This driverexposes sysfs ECS control attributes to userspace via /sys/bus/edac/devices//ecs_fruX/.The common sysfs ECS control interface abstracts the control of an arbitraryECS functionality to a common set of functions.Support for the ECS feature is added separately because the control attributesof the DDR5 ECS feature differ from those of the scrub feature.The sysfs ECS attribute nodes are only present if the client driver hasimplemented the corresponding attribute callback function and passed thenecessary operations to the EDAC RAS feature driver during registration.
