The state machine for each ap queue covered a mixture of device states and state machine (firmware queue state) states. This patch splits the device states and the state machine states into two different enums and variables. The major state is the device state with currently these values: AP_DEV_STATE_UNINITIATED - fresh and virgin, not touched AP_DEV_STATE_OPERATING - queue dev is working normal AP_DEV_STATE_SHUTDOWN - remove/unbind/shutdown in progress AP_DEV_STATE_ERROR - device is in error state only when the device state is > UNINITIATED the state machine is run. The state machine represents the states of the firmware queue: AP_SM_STATE_RESET_START - starting point, reset (RAPQ) ap queue AP_SM_STATE_RESET_WAIT - reset triggered, waiting to be finished if irqs enabled, set up irq (AQIC) AP_SM_STATE_SETIRQ_WAIT - enable irq triggered, waiting to be finished, then go to IDLE AP_SM_STATE_IDLE - queue is operational but empty AP_SM_STATE_WORKING - queue is operational, requests are stored and replies may wait for getting fetched AP_SM_STATE_QUEUE_FULL - firmware queue is full, so only replies can get fetched For debugging each ap queue shows a sysfs attribute 'states' which displays the device and state machine state and is only available when the kernel is build with CONFIG_ZCRYPT_DEBUG enabled.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
