EDAC, skx_edac: Add EDAC driver for Skylake

2016-08-21T17:58:34+00:00

This is an entirely new driver instead of yet another set of patches
to sb_edac.c because:

1) Mapping from PCI devices to socket/memory controller is significantly
   different. Skylake scatters devices on a socket across a number of
   PCI buses.
2) There is an extra level of interleaving via the "mcroute" register
   that would be a little messy to squeeze into the old driver.
3) Validation is getting too expensive. Changes to sb_edac need to
   be checked against Sandy Bridge, Ivy Bridge, Haswell, Broadwell and
   Knights Landing.

EDAC, altera: Add Altera L2 cache and OCRAM support

2016-02-11T11:23:06+00:00

Add L2 Cache and On-Chip RAM EDAC support for the Altera SoCs. The SDRAM
controller is using the Memory Controller model.

Each type of ECC is individually configurable.

EDAC: Rework workqueue handling

2015-12-11T15:56:43+00:00

Hide the EDAC workqueue pointer in a separate compilation unit and add
accessors for the workqueue manipulations needed.

Remove edac_pci_reset_delay_period() which wasn't used by anything. It
seems it got added without a user with

EDAC: Carve out debugfs functionality

2015-09-22T10:29:46+00:00

... into a separate compilation unit and drop a couple of
CONFIG_EDAC_DEBUG ifdefferies. Rename edac_create_debug_nodes() to
edac_create_debugfs_nodes(), while at it.

No functionality change.

x86/ras: Move AMD MCE injector to arch/x86/ras/

2015-08-13T08:12:54+00:00

This is an x86-specific module and would benefit from being
closer to the arch code. Move it there. Update copyright while
at it.

EDAC, synps: Add EDAC support for zynq ddr ecc controller

2015-01-07T10:42:05+00:00

Add EDAC support for ecc errors reporting on the synopsys ddr
controller. The ddr ecc controller corrects single bit errors and
detects double bit errors.

Selected important-ish notes from the changelog:

- I have not taken care of spliting synps_edac_geterror_info function as
it adds additional indentation levels and moreover the existing changes
were made as part of the v2 review comments

- Removed dt binding info as already there is a binding info available
under memorycontroller. so, updated ecc info there.

- Shortened the prefix "sysnopsys" to "synps"

EDAC, pci_sysfs: remove unneccessary ifdef around entire file

2014-11-11T17:17:57+00:00

The file edac_pci_sysfs.c is dependent on CONFIG_PCI. This is already
modelled in the Makefile, but edac_pci_sysfs.o is still contained in
the list of files compiled even without CONFIG_PCI.

This change removes edac_pci_sysfs.o from the list of built objects
when not having CONFIG_PCI enabled and removes the then-unnecessary
ifdef from the source file.

edac: altera: Add Altera SDRAM EDAC support

2014-09-04T18:41:46+00:00

This patch adds support for the CycloneV and ArriaV SDRAM controllers.
Correction and reporting of SBEs, Panic on DBEs.

There was a discussion thread on whether this driver should be an mfd driver
or just make use of syscon, which is already a mfd. Ultimately, the
decision to use a simple syscon interface was reached.[1]

ie31200_edac: Introduce the driver

2014-07-04T12:00:26+00:00

Add a driver for the E3-1200 series of Intel DRAM controllers, based on
the following E3-1200 specs:

http://www.intel.com/content/www/us/en/processors/xeon/xeon-e3-1200-family-vol-2-datasheet.html
http://www.intel.com/content/www/us/en/processors/xeon/xeon-e3-1200v3-vol-2-datasheet.html

I've tested this on bad memory hardware, and observed correlating bad
reads and uncorrected memory errors as reported by the driver.

Tested against:

CPU E3-1270 v3 @ 3.50GHz : 8086:0c08 (haswell)
CPU E3-1270 V2 @ 3.50GHz : 8086:0158 (ivy bridge)
CPU E31270 @ 3.40GHz : 8086:0108 (sandy bridge)
