EDAC: Drop obsolete PPC4xx driver

2024-09-05T14:56:38+00:00

Since 47d13a269bbd ("powerpc/40x: Remove 40x platforms.") support for PPC40x platforms has been removed. While the EDAC driver also mentions PPC440 and PPC460 processors, the driver refuses to probe on anything other than PPC405. It's unlikely support will ever be added at this point for these other old platforms, so the driver can be removed.

EDAC, i10nm: make skx_common.o a separate module

2024-05-29T20:30:10+00:00

Commit 598afa050403 ("kbuild: warn objects shared among multiple modules") was added to track down cases where the same object is linked into multiple modules. This can cause serious problems if some modules are builtin while others are not. That test triggers this warning: scripts/Makefile.build:236: drivers/edac/Makefile: skx_common.o is added to multiple modules: i10nm_edac skx_edac Make this a separate module instead.

EDAC/versal: Add a Xilinx Versal memory controller driver

2023-10-23T17:41:27+00:00

Add a EDAC driver for the RAS capabilities on the Xilinx integrated DDR Memory Controllers (DDRMCs) which support both DDR4 and LPDDR4/4X memory interfaces. It has four programmable Network-on-Chip (NoC) interface ports and is designed to handle multiple streams of traffic. The driver reports correctable and uncorrectable errors, and also creates debugfs entries for testing through error injection.

EDAC/zynqmp: Add EDAC support for Xilinx ZynqMP OCM

2023-01-09T10:13:58+00:00

Add EDAC support for Xilinx ZynqMP OCM Controller, so this driver reports CE and UE errors upon interrupt generation. Also add debugfs files for error injection. On Xilinx ZynqMP platform, both OCM Controller driver(zynqmp_edac) and DDR Memory Controller driver(synopsys_edac) co-exist which means both can be loaded at a time. This scenario is tested on Xilinx ZynqMP platform.

EDAC/amd64: Merge error injection sysfs facilities

2020-12-28T18:36:25+00:00

Merge them into the main driver and put them inside an EDAC_DEBUG ifdeffery to simplify the driver and have all debugging/injection stuff behind a debug build-time switch. No functional changes.

EDAC/amd64: Merge sysfs debugging attributes setup code

2020-12-28T18:36:17+00:00

There's no need for them to be in a separate file so merge them into the main driver compilation unit like the other EDAC drivers do. Drop now-unneeded function export, make the function static and shorten static function names. No functional changes.

EDAC/mv64x60: Remove orphan mv64x60 driver

2020-12-07T11:16:02+00:00

The mv64x60 EDAC driver depends on CONFIG_MV64X60. But that symbol is not user-selectable, and the last code that selected it was removed with the C2K board support in 2018, see: 92c8c16f3457 ("powerpc/embedded6xx: Remove C2K board support") That means the driver is now dead code, so remove it.

EDAC/igen6: Add EDAC driver for Intel client SoCs using IBECC

2020-11-19T20:51:17+00:00

This driver supports Intel client SoC with integrated memory controller using In-Band ECC(IBECC). The memory correctable and uncorrectable errors are reported via NMIs. The driver handles the NMIs and decodes the memory error address to platform specific address. The first IBECC-supported SoC is Elkhart Lake.
