Pull EDAC fixes and ghes-edac from Mauro Carvalho Chehab:
"For:
- Some fixes at edac drivers (i7core_edac, sb_edac, i3200_edac);
- error injection support for i5100, when EDAC debug is enabled;
- fix edac when it is loaded builtin (early init for the subsystem);
- a "Firmware First" EDAC driver, allowing ghes to report errors via
EDAC (ghes-edac).
With regards to ghes-edac, this fixes a longstanding BZ at Red Hat
that happens with Nehalem and Sandy Bridge CPUs: when both GHES and
i7core_edac or sb_edac are running, the error reports are
unpredictable, as both BIOS and OS race to access the registers. With
ghes-edac, the EDAC core will refuse to register any other concurrent
memory error driver.
This patchset moves the ghes struct definitions to a separate header
file (include/acpi/ghes.h) and adds 3 hooks at apei/ghes.c to
register/unregister and to report errors via ghes-edac. Those changes
were acked by ghes driver maintainer (Huang)."
* 'linux_next' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-edac: (30 commits)
i5100_edac: convert to use simple_open()

ghes_edac: Make it compliant with UEFI spec 2.3.1
ghes_edac: Improve driver's printk messages
ghes_edac: Don't credit the same memory dimm twice
ghes_edac: do a better job of filling EDAC DIMM info
ghes_edac: add support for reporting errors via EDAC
ghes_edac: Register at EDAC core the BIOS report
ghes: add the needed hooks for EDAC error report
ghes: move structures/enum to a header file
edac: add support for error type "Info"
edac: add support for raw error reports
edac: reduce stack pressure by using a pre-allocated buffer
edac: lock module owner to avoid error report conflicts
edac: remove proc_name from mci structure
edac: add a new memory layer type
edac: initialize the core earlier
edac: better report error conditions in debug mode

EDAC is designed to report errors in the core system.
|
|
These are low-level errors that are reported in the CPU or
|
|
supporting chipset or other subsystems:
|
|
memory errors, cache errors, PCI errors, thermal throttling, etc..
|
|
If unsure, select 'Y'.
|
|
|
|
If this code is reporting problems on your system, please
|
|
see the EDAC project web pages for more information at:

and:

help

Some systems are able to detect and correct errors in main
|
|
memory. EDAC can report statistics on memory error
|
|
detection and correction (EDAC - or commonly referred to ECC
|
|
errors). EDAC will also try to decode where these errors
|
|
occurred so that a particular failing memory module can be
|

replaced. If unsure, select 'Y'.

|
|
help
|
|
Not all machines support hardware-driven error report. Some of those
|
|
provide a BIOS-driven error report mechanism via ACPI, using the
|
|
APEI/GHES driver. By enabling this option, the error reports provided
|
|
by GHES are sent to userspace via the EDAC API.
|
|
|
|
When this option is enabled, it will disable the hardware-driven
|
|
mechanisms, if a GHES BIOS is detected, entering into the
|
|
"Firmware First" mode.
|
|
|
|
It should be noticed that keeping both GHES and a hardware-driven
|
|
error mechanism won't work well, as BIOS will race with OS, while
|
|
reading the error registers. So, if you want to not use "Firmware
|
|
first" GHES error mechanism, you should disable GHES either at
|
|
compilation time or by passing "ghes.disable=1" Kernel parameter
|
|
at boot time.
|
|
|
|
In doubt, say 'Y'.
