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.
[ bp:
- Add a pointer to the documentation about the register unlock code.
- Squash in a fix for a Smatch static checker issue as reported by
Dan Carpenter:

EDAC is a subsystem along with hardware-specific drivers designed to
|
|
report hardware errors. These are low-level errors that are reported
|
|
in the CPU or supporting chipset or other subsystems:
|
|
memory errors, cache errors, PCI errors, thermal throttling, etc..
|
|
If unsure, select 'Y'.

The mailing list for the EDAC project is linux-edac@vger.kernel.org.

This turns on debugging information for the entire EDAC subsystem.

You do so by inserting edac_module with "edac_debug_level=x." Valid

Usually you should select 'N' here.

|
|
Not all machines support hardware-driven error report. Some of those
|
|
provide a BIOS-driven error report mechanism via ACPI, using the
|
|
APEI/GHES driver. By enabling this option, the error reports provided
|
|
by GHES are sent to userspace via the EDAC API.
|
|
|
|
When this option is enabled, it will disable the hardware-driven
|
|
mechanisms, if a GHES BIOS is detected, entering into the
|
|
"Firmware First" mode.
|
|
|
|
It should be noticed that keeping both GHES and a hardware-driven
|
|
error mechanism won't work well, as BIOS will race with OS, while
|
|
reading the error registers. So, if you want to not use "Firmware
|
|
first" GHES error mechanism, you should disable GHES either at
|
|
compilation time or by passing "ghes.disable=1" Kernel parameter
|
|
at boot time.
|
|
|
|
In doubt, say 'Y'.

When EDAC_DEBUG is enabled, hardware error injection facilities
|
|
through sysfs are available:
|
|
|
|
AMD CPUs up to and excluding family 0x17 provide for Memory
|
|
Error Injection into the ECC detection circuits. The amd64_edac
|
|
module allows the operator/user to inject Uncorrectable and
|
|
Correctable errors into DRAM.
|
|
|
|
When enabled, in each of the respective memory controller directories
|
|
(/sys/devices/system/edac/mc/mcX), there are 3 input files:
|
|
|

- inject_section (0..3, 16-byte section of 64-byte cacheline),
|
|
- inject_word (0..8, 16-bit word of 16-byte section),
|
|
- inject_ecc_vector (hex ecc vector: select bits of inject word)
|
|
|
|
In addition, there are two control files, inject_read and inject_write,
|
|
which trigger the DRAM ECC Read and Write respectively.
