EDAC/mpc85xx: Prevent building as a module

2019-06-15T09:54:52+00:00

[ 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, ghes: Do not enable it by default

2017-04-27T12:15:38+00:00

Leave it to the user to decide whether to enable this or not. Otherwise, platform-specific drivers won't initialize (currently, EDAC supports only a single platform driver loaded). Signed-off-by: Borislav Petkov

EDAC: Remove EDAC_MM_EDAC

2017-04-10T15:14:41+00:00

Move all the EDAC core functionality behind CONFIG_EDAC and get rid of that indirection. Update defconfigs which had it. While at it, fix dependencies such that EDAC depends on RAS for the tracepoints.

EDAC, thunderx: Add Cavium ThunderX EDAC driver

EDAC, pnd2_edac: Add new EDAC driver for Intel SoC platforms

2017-03-16T11:40:52+00:00

Initial target for this driver is the Intel Apollo Lake platform and Denverton micro-server, they use the same internal memory controller IP called Pondicherry2. Memory controller registers are not in PCI config space like earlier Intel memory controllers. For Apollo Lake platform they are accessed via a "side-band" interface, for Denverton micro-server they are access via PCI config space and memory map I/O. This driver is for Apollo Lake and Denverton, but only the Denverton is fully enabled while we wait for the sideband driver. Apollo lake driver and initial cut at Denverton driver by Tony Luck. Extensive cleanup, refactoring and basic verification by Qiuxu Zhuo.

EDAC, skx_edac: Add EDAC driver for Skylake

2016-08-21T17:58:34+00:00

This is an entirely new driver instead of yet another set of patches to sb_edac.c because: 1) Mapping from PCI devices to socket/memory controller is significantly different. Skylake scatters devices on a socket across a number of PCI buses. 2) There is an extra level of interleaving via the "mcroute" register that would be a little messy to squeeze into the old driver. 3) Validation is getting too expensive. Changes to sb_edac need to be checked against Sandy Bridge, Ivy Bridge, Haswell, Broadwell and Knights Landing.
