EDAC: Rework workqueue handling

2015-12-11T15:56:43Z

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 91b99041c1d5 ("drivers/edac: updated PCI monitoring") Signed-off-by: Borislav Petkov

EDAC: Carve out debugfs functionality

2015-09-22T10:29:46Z

... 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. Cc: Signed-off-by: Borislav Petkov

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

2015-08-13T08:12:54Z

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

2015-01-07T10:42:05Z

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, pci_sysfs: remove unneccessary ifdef around entire file

2014-11-11T17:17:57Z

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

2014-09-04T18:41:46Z

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

ghes_edac: Register at EDAC core the BIOS report

2013-02-25T22:42:12Z

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. Signed-off-by: Mauro Carvalho Chehab

MIPS: Cavium: Add EDAC support.

2012-12-12T15:48:49Z

Drivers for EDAC on Cavium. Supported subsystems are: o CPU primary caches. These are parity protected only, so only error reporting. o Second level cache - ECC protected, provides SECDED. o Memory: ECC / SECDEC if used with suitable DRAM modules. The driver will will only initialize if ECC is enabled on a system so is safe to run on non-ECC memory. o PCI: Parity error reporting Since it is very hard to test this sort of code the implementation is very conservative and uses polling where possible for now.
