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)

ghes_edac: Register at EDAC core the BIOS report

2013-02-25T22:42:12+00:00

Register GHES at EDAC MC core, in order to avoid other
drivers to also handle errors and mangle with error data.

The edac core will warrant that just one driver will be used,
so the first one to register (BIOS first) will be the one that
will be reporting the hardware errors.

For now, the EDAC driver does nothing but to register at the
EDAC core, preventing the hardware-driven mechanism to
interfere with GHES.
