Merge branch 'ras-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2017-02-20T20:47:44+00:00

Pull RAS updates from Ingo Molnar:
 "The main changes in this cycle were:

  - Assign notifier chain priorities for all RAS related handlers to
    make the ordering explicit (Borislav Petkov)

  - Improve the AMD MCA banks sysfs output (Yazen Ghannam)

  - Various cleanups and restructuring of the x86 RAS code (Borislav
    Petkov)"

* 'ras-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/ras, EDAC, acpi: Assign MCE notifier handlers a priority
  x86/ras: Get rid of mce_process_work()
  EDAC/mce/amd: Dump TSC value
  EDAC/mce/amd: Unexport amd_decode_mce()
  x86/ras/amd/inj: Change dependency
  x86/ras: Flip the TSC-adding logic
  x86/ras/amd: Make sysfs names of banks more user-friendly
  x86/ras/therm_throt: Do not log a fake MCE for thermal events
  x86/ras/inject: Make it depend on X86_LOCAL_APIC=y

EDAC, mce_amd: Print IPID and Syndrome on a separate line

2017-02-16T14:39:32+00:00

Currently, the IPID and Syndrome are printed on the same line as the
Address. There are cases when we can have a valid Syndrome but not a
valid Address.

For example, the MCA_SYND register can be used to hold more detailed
error info that the hardware folks can use. It's not just DRAM ECC
syndromes. There are some error types that aren't related to memory that
may have valid syndromes, like some errors related to links in the Data
Fabric, etc.

In these cases, the IPID and Syndrome are not printed at the same log
level as the rest of the stanza, so users won't see them on the console.

Console:
  [Hardware Error]: CPU:16 (17:1:0) MC22_STATUS[Over|CE|MiscV|-|-|-|-|SyndV|-]: 0xd82000000002080b
  [Hardware Error]: Power, Interrupts, etc. Extended Error Code: 2

Dmesg:
  [Hardware Error]: CPU:16 (17:1:0) MC22_STATUS[Over|CE|MiscV|-|-|-|-|SyndV|-]: 0xd82000000002080b
  , Syndrome: 0x000000010b404000, IPID: 0x0001002e00000002
  [Hardware Error]: Power, Interrupts, etc. Extended Error Code: 2

Print the IPID first and on a new line. The IPID should always be
printed on SMCA systems. The Syndrome will then be printed with the IPID
and at the same log level when valid:

  [Hardware Error]: CPU:16 (17:1:0) MC22_STATUS[Over|CE|MiscV|-|-|-|-|SyndV|-]: 0xd82000000002080b
  [Hardware Error]: IPID: 0x0001002e00000002, Syndrome: 0x000000010b404000
  [Hardware Error]: Power, Interrupts, etc. Extended Error Code: 2

EDAC, mce_amd: Give more context to deferred error message

2017-01-28T12:03:29+00:00

Users may not be familiar with the concept of deferred errors. There is
no action for users to take on this type of error, so give more context
in the error message to make this more clear.

x86/ras, EDAC, acpi: Assign MCE notifier handlers a priority

2017-01-24T08:14:57+00:00

Assign all notifiers on the MCE decode chain a priority so that they get
called in the correct order.

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. ]
