Families up to and including 0x16 allow access to the injection hardware. Starting with family 0x17, access to those registers is blocked by security policy. Limit that only on the families which support it.

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'.

This turns on debugging information for the entire EDAC subsystem.

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

levels are 0-4 (from low to high) and by default it is set to 2.
|

Usually you should select 'N' here.

help
|
|
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.
