      x86/mce: Take action on UCNA/Deferred errors again · 8438b84a
      由 Jan H. Schönherr 提交于 
      Commit

  fa92c586 ("x86, mce: Support memory error recovery for both UCNA
		and Deferred error in machine_check_poll")

added handling of UCNA and Deferred errors by adding them to the ring
for SRAO errors.

Later, commit

  fd4cf79f ("x86/mce: Remove the MCE ring for Action Optional errors")

switched storage from the SRAO ring to the unified pool that is still
in use today. In order to only act on the intended errors, a filter
for MCE_AO_SEVERITY is used -- effectively removing handling of
UCNA/Deferred errors again.

Extend the severity filter to include UCNA/Deferred errors again.
Also, generalize the naming of the notifier from SRAO to UC to capture
the extended scope.

Note, that this change may cause a message like the following to appear,
as the same address may be reported as SRAO and as UCNA:

 Memory failure: 0x5fe3284: already hardware poisoned

Technically, this is a return to previous behavior.

      EDAC/mce_amd: Decode MCA_STATUS[Scrub] bit · 3f4da372
      由 Yazen Ghannam 提交于 
      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.

      x86/MCE/AMD, EDAC/mce_amd: Add new McaTypes for CS, PSP, and SMU units · 3ad7e748
      由 Yazen Ghannam 提交于 
      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.

      由 Vishal Verma 提交于 
      The NFIT machine check handler uses the physical address from the mce
structure, and compares it against information in the ACPI NFIT table
to determine whether that location lies on an NVDIMM. The mce->addr
field however may not always be valid, and this is indicated by the
MCI_STATUS_ADDRV bit in the status field.

Export mce_usable_address() which already performs validation for the
address, and use it in the NFIT handler.

      acpi/nfit, x86/mce: Handle only uncorrectable machine checks · 5d96c934
      由 Vishal Verma 提交于 
      The MCE handler for nfit devices is called for memory errors on a
Non-Volatile DIMM and adds the error location to a 'badblocks' list.
This list is used by the various NVDIMM drivers to avoid consuming known
poison locations during IO.

The MCE handler gets called for both corrected and uncorrectable errors.
Until now, both kinds of errors have been added to the badblocks list.
However, corrected memory errors indicate that the problem has already
been fixed by hardware, and the resulting interrupt is merely a
notification to Linux.

As far as future accesses to that location are concerned, it is
perfectly fine to use, and thus doesn't need to be included in the above
badblocks list.

Add a check in the nfit MCE handler to filter out corrected mce events,
and only process uncorrectable errors.

      x86/mce/AMD, EDAC/mce_amd: Enumerate Reserved SMCA bank type · 68627a69
      由 Yazen Ghannam 提交于 
      Currently, bank 4 is reserved on Fam17h, so we chose not to initialize
bank 4 in the smca_banks array. This means that when we check if a bank
is initialized, like during boot or resume, we will see that bank 4 is
not initialized and try to initialize it.

This will cause a call trace, when resuming from suspend, due to
rdmsr_*on_cpu() calls in the init path. The rdmsr_*on_cpu() calls issue
an IPI but we're running with interrupts disabled. This triggers:

  WARNING: CPU: 0 PID: 11523 at kernel/smp.c:291 smp_call_function_single+0xdc/0xe0
  ...

Reserved banks will be read-as-zero, so their MCA_IPID register will be
zero. So, like the smca_banks array, the threshold_banks array will not
have an entry for a reserved bank since all its MCA_MISC* registers will
be zero.

Enumerate a "Reserved" bank type that matches on a HWID_MCATYPE of 0,0.

Use the "Reserved" type when checking if a bank is reserved. It's
possible that other bank numbers may be reserved on future systems.

Don't try to find the block address on reserved banks.

      License cleanup: add SPDX GPL-2.0 license identifier to files with no license · b2441318
      由 Greg Kroah-Hartman 提交于 
      Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

      Export the function which checks whether an MCE is a memory error to
other users so that we can reuse the logic. Drop the boot_cpu_data use,
while at it, as mce.cpuvendor already has the CPU vendor in there.

Integrate a piece from a patch from Vishal Verma
<vishal.l.verma@intel.com> to export it for modules (nfit).

The main reason we're exporting it is that the nfit handler
nfit_handle_mce() needs to detect a memory error properly before doing
its recovery actions.

      x86/mce/AMD: Add system physical address translation for AMD Fam17h · f5382de9
      由 Yazen Ghannam 提交于 
      The Unified Memory Controllers (UMCs) on Fam17h log a normalized address
in their MCA_ADDR registers. We need to convert that normalized address
to a system physical address in order to support a few facilities:

1) To offline poisoned pages in DRAM proactively in the deferred error
   handler.

2) To print sysaddr and page info for DRAM ECC errors in EDAC.

[ Boris: fixes/cleanups ontop:

  * hi_addr_offset = 0 - no need for that branch. Stick it all under the
    HiAddrOffsetEn case. It confines hi_addr_offset's declaration too.

  * Move variables to the innermost scope they're used at so that we save
    on stack and not blow it up immediately on function entry.

  * Do not modify *sys_addr prematurely - we want to not exit early and
    have modified *sys_addr some, which callers get to see. We either
    convert to a sys_addr or we don't do anything. And we signal that with
    the retval of the function.

  * Rename label out -> out_err - because it is the error path.

  * No need to pr_err of the conversion failed case: imagine a
    sparsely-populated machine with UMCs which don't have DIMMs. Callers
    should look at the retval instead and issue a printk only when really
    necessary. No need for useless info in dmesg.

  * s/temp_reg/tmp/ and other variable names shortening => shorter code.

  * Use BIT() everywhere.

  * Make error messages more informative.

  *  Small build fix for the !CONFIG_X86_MCE_AMD case.

  * ... and more minor cleanups.

      x86/mce/AMD: Fix HWID_MCATYPE calculation by grouping arguments · 859af13a
      由 Yazen Ghannam 提交于 
      The calculation of the hwid_mcatype value in get_smca_bank_info()
became incorrect after applying the following commit:

  1ce9cd7f ("x86/RAS: Simplify SMCA HWID descriptor struct")

This causes the function to not match a bank to its type.

Disassembly of hwid_mcatype calculation after change:

      db:       8b 45 e0                mov    -0x20(%rbp),%eax
      de:       41 89 c4                mov    %eax,%r12d
      e1:       25 00 00 ff 0f          and    $0xfff0000,%eax
      e6:       41 c1 ec 10             shr    $0x10,%r12d
      ea:       41 09 c4                or     %eax,%r12d

Disassembly of hwid_mcatype calculation in original code:

     286:       8b 45 d0                mov    -0x30(%rbp),%eax
     289:       41 89 c5                mov    %eax,%r13d
     28c:       c1 e8 10                shr    $0x10,%eax
     28f:       41 81 e5 ff 0f 00 00    and    $0xfff,%r13d
     296:       41 c1 e5 10             shl    $0x10,%r13d
     29a:       41 09 c5                or     %eax,%r13d

Grouping the arguments to the HWID_MCATYPE() macro fixes the issue.

( Boris suggested adding parentheses in the macro. )

      x86/mce: Define vendor-specific MSR accessors · a9750a31
      由 Yazen Ghannam 提交于 
      Scalable MCA processors have a whole new range of MSR addresses to
obtain bank related info such as CTL, MISC, ADDR, STATUS. Therefore, we
need a way to abstract the MSR addresses per vendor.
