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

2015-01-07T10:42:05Z

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" Signed-off-by: Punnaiah Choudary Kalluri Link: http://lkml.kernel.org/r/a728a8d4678f4dbf9de189a480297c3d@BY2FFO11FD034.protection.gbl [ Boris: massage commit message. ] Signed-off-by: Borislav Petkov

EDAC, mce_amd_inj: Convert mce_amd_inj module to debugfs

2014-11-25T12:09:33Z

This module's interface belongs in debugfs, not in sysfs. Signed-off-by: Borislav Petkov

amd64_edac: Build module on x86-32

2014-11-05T14:54:34Z

By popular demand, enable amd64_edac on 32-bit too. Boris: - update Kconfig text. - add a warning on load which states that 32-bit configurations are unsupported. Signed-off-by: Tomasz Pala Link: http://lkml.kernel.org/r/20141102102212.GA7034@polanet.pl Signed-off-by: Borislav Petkov

edac: altera: Add Altera SDRAM EDAC support

2014-09-04T18:41:46Z

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] [1] https://lkml.org/lkml/2014/7/30/514 [dinguyen] Fixed Kconfig to have EDAC_ALTERA_MC as a tristate to prevent a build failure for allmodconfig.

ie31200_edac: Introduce the driver

2014-07-04T12:00:26Z

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) Signed-off-by: Jason Baron Link: http://lkml.kernel.org/r/95c83e80dd40b5377e8bb206285c5d95ac623872.1403818526.git.jbaron@akamai.com [ Boris: realign defines ] Signed-off-by: Borislav Petkov

sb_edac: add support for Haswell based systems

2014-06-26T18:47:01Z

trace, RAS: Add basic RAS trace event

2014-06-23T17:12:19Z

To avoid confuision and conflict of usage for RAS related trace event, add an unified RAS trace event stub. Start a RAS subsystem menu which will be fleshed out in time, when more features get added to it.
