EDAC/altera: Add separate SDRAM EDAC config

2019-02-26T15:18:57Z

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.

EDAC/mce_amd: Decode MCA_STATUS in bit definition order

EDAC/mce_amd: Decode MCA_STATUS[Scrub] bit

2019-02-15T13:25:58Z

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. Signed-off-by: Yazen Ghannam Signed-off-by: Borislav Petkov Cc: "H.

EDAC, altera: Add missing of_node_put()

2019-02-15T11:02:47Z

The call to of_parse_phandle() returns a node pointer with refcount incremented thus it must be explicitly decremented here after the last usage.

EDAC, skx_common: Add code to recognise new compound error code

2019-02-06T10:03:06Z

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.

EDAC, i10nm: Fix randconfig builds

I10NM_EDAC depends on CONFIG_ACPI so make that dependency explicit.

EDAC, mce_amd: Print ExtErrorCode and description on a single line

2019-02-04T18:29:13Z

Save a log line by printing the extended error code and the description on a single line. This is similar to how errors are printed in other subsystems, e.g. "#, description". If we don't have a valid description then only the number/code is printed.

EDAC, mce_amd: Match error descriptions to latest documentation

2019-02-03T12:16:50Z

Update the error descriptions to match the latest documentation for easier searching. In some cases the changes are small and in other cases the changes may be total rewording of the description. No functional changes.
