The Compress and Verify (CnV) feature check and ensures data integrity
in the compression operation. The implementation of CnV keeps a record
of the CnV errors that have occurred since the driver was loaded.

Expose CnV error stats by providing the "cnv_errors" file under
debugfs. This includes the number of errors detected up to now and
the type of the last error. The error count is provided on a per
Acceleration Engine basis and it is reset every time the driver is loaded.

QAT devices implement a mechanism that allows them to go autonomously
to a low power state depending on the load.

Expose power management info by providing the "pm_status" file under
debugfs. This includes PM state, PM event log, PM event counters, PM HW
CSRs, per-resource type constrain counters and per-domain power gating
status specific to the QAT device.

This information is retrieved from (1) the FW by means of
ICP_QAT_FW_PM_INFO command, (2) CSRs and (3) counters collected by the
device driver.

In addition, add logic to keep track and report power management event
interrupts and acks/nacks sent to FW to allow/prevent state transitions.

and decryption have minimum requirements on the number of device
queues. If the number of queues does not meet the requirement,
the process initialization will fail. Therefore, the driver checks
the number of queues on the device before registering the algorithm.
If the number does not meet the requirements, the driver does not register
the algorithm to crypto subsystem, the device is still added to the

If the queue isolation feature is enabled, the number of queues
supported by the device changes. When PF is enabled using the
current default number of queues, the default number of queues may
be greater than the number supported by the device. As a result,
the PF fails to be bound to the driver.

After modification, if queue isolation feature is enabled, when
the default queue parameter is greater than the number supported
by the device, the number of enabled queues will be changed to
the number supported by the device, so that the PF and driver
can be properly bound.

Currently, the alignment of each field in struct aesni_xts_ctx occurs
right before every access. However, it's possible to perform this
alignment ahead of time.

Introduce a helper function that converts struct crypto_skcipher *tfm
to struct aesni_xts_ctx *ctx and returns an aligned address. Utilize
this helper function at the beginning of each XTS function and then
eliminate redundant alignment code.
