Description:
(WO) Writing an integer to this file injects the corresponding
CXL protocol error into $dport_dev ($dport_dev will be a device
name from /sys/bus/pci/devices). The integer to type mapping for
injection can be found by reading from einj_types. If the dport
was enumerated in RCH mode, a CXL 1.1 error is injected, otherwise
a CXL 2.0 error is injected.

What: /sys/kernel/debug/qat_<device>_<BDF>/heartbeat/inject_error
Date: March 2024
KernelVersion: 6.8
Contact: qat-linux@intel.com
Description: (WO) Write to inject an error that simulates an heartbeat
failure. This is to be used for testing purposes.

After writing this file, the driver stops arbitration on a
random engine and disables the fetching of heartbeat counters.
If a workload is running on the device, a job submitted to the
accelerator might not get a response and a read of the
`heartbeat/status` attribute might report -1, i.e. device
unresponsive.
The error is unrecoverable thus the device must be restarted to
restore its functionality.

This attribute is available only when the kernel is built with
CONFIG_CRYPTO_DEV_QAT_ERROR_INJECTION=y.

A write of 1 enables error injection.

The following example shows how to enable error injection::

# cd /sys/kernel/debug/qat_<device>_<BDF>
# echo 1 > heartbeat/inject_error
