EDAC, skx: Fix randconfig builds

2018-10-31T18:24:21+00:00

The driver depends on the ADXL component glue and selects it. However, ADXL itself implicitly depends on ACPI and in nonsensical randconfig builds like this: # CONFIG_ACPI is not set CONFIG_ACPI_ADXL=y where ACPI is not enabled, the build fails with: drivers/edac/skx_edac.o: In function `skx_mce_check_error': skx_edac.c:(.text+0xab): undefined reference to `adxl_decode' drivers/edac/skx_edac.o: In function `skx_init': skx_edac.c:(.init.text+0x8bf): undefined reference to `adxl_get_component_names' make: *** [vmlinux] Error 1 Add stubs for that case so that the build succeeds. CONFIG_ACPI=n doesn't make any sense for real configurations but this fix will at least silence randconfig builds. Signed-off-by: Borislav Petkov Acked-by: Tony Luck Cc: "Rafael J. Wysocki"

EDAC, skx_edac: Add address translation for non-volatile DIMMs

2018-10-25T14:59:18+00:00

Currently, this driver doesn't support address translation for non-volatile DIMMs. The ACPI ADXL DSM method provides address translation for both volatile and non-volatile DIMMs. Enable it to use the ACPI DSM methods if they are supported and there are non-volatile DIMMs populated on the system.

drivers: edac: Add EDAC driver support for QCOM SoCs

2018-09-13T20:54:05+00:00

Add error reporting driver for Single Bit Errors (SBEs) and Double Bit Errors (DBEs). As of now, this driver supports error reporting for Last Level Cache Controller (LLCC) of Tag RAM and Data RAM. Interrupts are triggered when the errors happen in the cache, the driver handles those interrupts and dumps the syndrome registers.

EDAC, skx: Fix skx_edac build error when ACPI_NFIT=m

2018-05-14T09:35:23+00:00

Prevent build error when CONFIG_ACPI_NFIT=m and CONFIG_EDAC_SKX=y by limiting EDAC_SKX based on how ACPI_NFIT is set.

EDAC, altera: Add support for Stratix10 SDRAM EDAC

Support for Stratix10 SDRAM ECC requires the use of SMC calls to Secure Monitor for accessing registers.

edac: remove tile driver

2018-03-26T13:56:17+00:00

The Tile architecture is obsolete and getting removed from the kernel, this driver appears to only be used there, and not on the ARM based successors (Tile-Mx, BlueField), so we should remove it as well. Acked-by: Borislav Petkov Acked-by: Mauro Carvalho Chehab Signed-off-by: Arnd Bergmann

EDAC, skx_edac: Detect non-volatile DIMMs

2018-03-14T23:33:55+00:00

This just covers the topology function of the EDAC driver. We locate which DIMM slots are populated with NVDIMMs and query the NFIT and SMBIOS tables to get the size.

EDAC, layerscape: Allow building for LS1021A

2018-02-27T13:57:47+00:00

The LS1021A has a memory controller supported by this driver. It builds just fine, and I've done some rudimentary testing using the error injection facility, which suggests that it is indeed working.
