EDAC, skx: Fix randconfig builds in a better way

2018-11-07T21:58:29+00:00

It was previously noted that Kconfig complained about unmet dependencies
when trying to configure skx_edac together with CONFIG_ACPI=n. First fix
for this checked for ACPI when doing

  select ACPI_ADXL

but this required stub functions for the case where ACPI wasn't
selected. It also allowed building a driver that didn't actually work
for a system that has non-volatile DIMMs.

Arnd Bergmann pointed out that the right fix is to make EDAC_SKX
"depend on ACPI".

EDAC, synopsys: Add ECC support for ZynqMP DDR controller

2018-11-06T09:30:29+00:00

Add ECC support for ZynqMP DDR controller IP. The IP supports interrupts
for corrected and uncorrected errors. Add interrupt handlers for the
same.

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.

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.

Fixes this build error:
  drivers/edac/skx_edac.o: In function `get_nvdimm_info':
  ../drivers/edac/skx_edac.c:399: undefined reference to `nfit_get_smbios_id'

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.
