2019-02-26EDAC/altera: Add separate SDRAM EDAC configThor Thayer2-34/+47
The CONFIG_ALTERA_EDAC Kconfig symbol always enables the SDRAM EDAC functionality. On the newer architectures, however, there are cases where the peripheral EDAC functionality is enabled but SDRAM needs to be disabled. Move SDRAM functions so they can be contained inside the conditional CONFIG. Create new CONFIG option just for SDRAM.

2019-02-15EDAC/mce_amd: Decode MCA_STATUS[Scrub] bitYazen Ghannam1-0/+3
Previous AMD systems have had a bit in MCA_STATUS to indicate that an error was detected on a scrub operation. However, this bit was defined differently within different banks and families/models. Starting with Family 17h, MCA_STATUS[40] is either Reserved/Read-as-Zero or defined as "Scrub", for all MCA banks and CPU models. Therefore, this bit can be defined as the "Scrub" bit. Define MCA_STATUS[40] as "Scrub" and decode it in the AMD MCE decoding module for Family 17h and newer systems.

2019-02-06EDAC, skx_common: Add code to recognise new compound error codeTony Luck1-3/+5
A new error code for systems that use DRAM as an extra level of cache looks like: 000F 0010 1MMM CCCC where the MMM and CCCC bits are used for the same purpose as the original code. For this new class of errors the ADXL translation will provide details of both the DIMM used as cache for the error location and the component that is being cached. Note: This new error code is first supported in Skylake. Older EDAC drivers do not need to be updated.

2019-02-03x86/MCE/AMD, EDAC/mce_amd: Add new McaTypes for CS, PSP, and SMU unitsYazen Ghannam1-0/+55
The existing CS, PSP, and SMU SMCA bank types will see new versions (as indicated by their McaTypes) in future SMCA systems. Add the new (HWID, MCATYPE) tuples for these new versions. Reuse the same names as the older versions, since they are logically the same to the user. SMCA systems won't mix and match IP blocks with different McaType versions in the same system, so there isn't a need to distinguish them. The MCA_IPID register is saved when logging an MCA error, and that can be used to triage the error. Also, add the new error descriptions to edac_mce_amd. Some error types (positions in the list) are overloaded compared to the previous McaTypes. Therefore, just create new lists of the error descriptions to keep things simple even if some of the error descriptions are the same between versions.

It gets the memory capacity and topology information by reading the registers in PCI configuration space and memory-mapped I/O.

2018-11-07EDAC, skx: Fix randconfig builds in a better wayLuck, Tony1-2/+2
It was previously noted that Kconfig complained about unmet dependencies when trying to configure skx_edac together with CONFIG_ACPI=n. First fix for this checked for ACPI when doing select ACPI_ADXL but this required stub functions for the case where ACPI wasn't selected. It also allowed building a driver that didn't actually work for a system that has non-volatile DIMMs. Arnd Bergmann pointed out that the right fix is to make EDAC_SKX "depend on ACPI".

The driver depends on the ADXL component glue and selects it.
