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/amd64: Use new AMD Address Translation Library

2024-01-24T11:55:00+00:00

Remove old address translation code and use the new AMD Address Translation Library. Use "imply" in Kconfig so that the "AMD_ATL" config option takes the value of "EDAC_AMD64" as its default.

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/ghes: Make ghes_edac a proper module

2022-10-21T19:59:19+00:00

Commit dc4e8c07e9e2 ("ACPI: APEI: explicit init of HEST and GHES in apci_init()") introduced a bug leading to ghes_edac_register() to be invoked before edac_init(). Because at that time the bus "edac" hadn't been even registered, this created sysfs nodes as /devices/mc0 instead of /sys/devices/system/edac/mc/mc0 on an Ampere eMag server. Fix this by turning ghes_edac into a proper module. The list of GHES devices returned is not protected from being modified concurrently but it is pretty static as it gets created only during GHES init and latter is not a module so...

soc: sifive: ccache: Rename SiFive L2 cache to Composable cache.

2022-10-13T18:06:51+00:00

Since composable cache may be L3 cache if there is a L2 cache, we should use its original name composable cache to prevent confusion. There are some new lines were generated due to adding the compatible "sifive,ccache0" into ID table and indent requirement. The sifive L2 has been renamed to sifive CCACHE, EDAC driver needs to apply the change as well.
