EDAC/mpc85xx: Prevent building as a module

2019-06-15T09:52:55Z

[ Upstream commit 2b8358a951b1e2a534a54924cd8245e58a1c5fb8 ] The mpc85xx EDAC driver can be configured as a module but then fails to build because it uses two unexported symbols: ERROR: ".pci_find_hose_for_OF_device" [drivers/edac/mpc85xx_edac_mod.ko] undefined! ERROR: ".early_find_capability" [drivers/edac/mpc85xx_edac_mod.ko] undefined! We don't want to export those symbols just for this driver, so make the driver only configurable as a built-in. This seems to have been broken since at least c92132f59806 ("edac/85xx: Add PCIe error interrupt edac support") (Nov 2013).

EDAC/altera: Add separate SDRAM EDAC config

2019-02-26T15:18:57Z

The CONFIG_ALTERA_EDAC Kconfig symbol always enables the SDRAM EDAC functionality. On the newer architectures, however, there are cases where the peripheral EDAC functionality is enabled but SDRAM needs to be disabled. Move SDRAM functions so they can be contained inside the conditional CONFIG. Create new CONFIG option just for SDRAM.

EDAC, i10nm: Add a driver for Intel 10nm server processors

2019-02-02T12:33:18Z

This driver supports the Intel 10nm series server integrated memory controller. It gets the memory capacity and topology information by reading the registers in PCI configuration space and memory-mapped I/O. It decodes the memory error address to the platform specific address by using the ACPI Address Translation (ADXL) Device Specific Method (DSM).

EDAC, skx: Fix randconfig builds in a better way

2018-11-07T21:58:29Z

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, skx: Fix randconfig builds

2018-10-31T18:24:21Z

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

2018-10-25T14:59:18Z

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.
