+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>

+Description:
+		This file dumps a specified page table of Intel IOMMU
+		in legacy mode or scalable mode.
+
+		For a device that only supports legacy mode, dump its
+		page table by the debugfs file in the debugfs device
+		directory. e.g.
+		/sys/kernel/debug/iommu/intel/0000:00:02.0/domain_translation_struct.
+
+		For a device that supports scalable mode, dump the
+		page table of specified pasid by the debugfs file in
+		the debugfs pasid directory. e.g.
+		/sys/kernel/debug/iommu/intel/0000:00:02.0/1/domain_translation_struct.

+

+
+		 1) Dump the page table of device "0000:00:02.0" that only supports legacy mode.
