EDAC, mce_amd: Don't report poison bit on Fam15h, bank 4

2016-11-28T16:50:12+00:00

MCA_STATUS[43] has been defined as "Poison" or "Reserved" for every bank
since Fam15h except for Fam15h, bank 4 in which case it's defined as
part of the McaStatSubCache bitfield.

Filter out that case.

Merge tip:ras/core to pick up dependent changes

2016-11-23T20:13:40+00:00

tip:ras/core contains the respective Fam17h x86 RAS bits which
amd64_edac is going to use. So merge it into the EDAC branch.

EDAC, mce_amd: Rename nb_bus_decoder to dram_ecc_decoder

2016-11-21T08:43:15+00:00

nb_bus_decoder() is only used for DRAM ECC errors so rename it so that
the name is more generic and descriptive.

Also, call it for DRAM ECC errors on SMCA systems.

[ Boris: rename it to real function name with a verb in it. ]

x86/RAS: Hide SMCA bank names

2016-11-08T16:10:15+00:00

Add accessor functions and hide the smca_names array. Also, add a
sanity-check to bank HWID assignment in get_smca_bank_info().

x86/RAS: Rename smca_bank_names to smca_names

2016-11-08T16:10:14+00:00

Make it differ more from struct smca_bank_name for better readability.

x86/RAS: Simplify SMCA HWID descriptor struct

2016-11-08T16:10:14+00:00

Call it simply smca_hwid and call local variables "hwid". More readable.

x86/MCE/AMD, EDAC: Handle reserved bank 4 on Fam17h properly

2016-09-13T13:23:14+00:00

Bank 4 is reserved on family 0x17 and shouldn't generate any MCE
records. However, broken hardware and software is not something unheard
of so warn about bank 4 errors. They shouldn't be coming from bank 4
naturally but users can still use mce_amd_inj to simulate errors from it
for testing purposed.

Also, avoid special handling in the injector mce_amd_inj like it is
being done on the older families.

x86/mce, EDAC/mce_amd: Print MCA_SYND and MCA_IPID during MCE on SMCA systems

2016-09-13T13:23:13+00:00

The MCA_SYND and MCA_IPID registers contain valuable information and
should be included in MCE output. The MCA_SYND register contains
syndrome and other error information, and the MCA_IPID register will
uniquely identify the MCA bank's type without having to rely on system
software.

x86/mce/AMD, EDAC/mce_amd: Define and use tables for known SMCA IP types

2016-09-13T13:23:10+00:00

Scalable MCA defines a number of IP types. An MCA bank on an SMCA
system is defined as one of these IP types. A bank's type is uniquely
identified by the combination of the HWID and MCATYPE values read from
its MCA_IPID register.

Add the required tables in order to be able to lookup error descriptions
based on a bank's type and the error's extended error code.

EDAC/mce_amd: Use SMCA prefix for error descriptions arrays

2016-09-13T13:23:09+00:00

The error descriptions defined for Fam17h can be reused for other SMCA
systems, so their names should reflect this.

Change f17h prefix to smca for error descriptions.
