2024-09-05EDAC: Drop obsolete PPC4xx driverRob Herring (Arm)1-9/+0
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.

2023-10-23EDAC/versal: Add a Xilinx Versal memory controller driverShubhrajyoti Datta1-0/+12
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.

2022-10-21EDAC/ghes: Make ghes_edac a proper moduleJia He1-2/+2
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...

2018-10-31EDAC, skx: Fix randconfig buildsBorislav Petkov1-1/+1
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.

2018-10-25EDAC, skx_edac: Add address translation for non-volatile DIMMsQiuxu Zhuo1-0/+1
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.

2018-09-13drivers: edac: Add EDAC driver support for QCOM SoCsChannagoud Kadabi1-0/+14
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.

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.
