The zcrypt api provides a new function to wait until the zcrypt api is operational: int zcrypt_wait_api_operational(void); The AP bus scan and the binding of ap devices to device drivers is an asynchronous job. This function waits until these initial jobs are done and so the zcrypt api should be ready to serve crypto requests - if there are resources available. The function uses an internal timeout of 60s. The very first caller will either wait for ap bus bindings complete or the timeout happens. This state will be remembered for further callers which will only be blocked until a decision is made (timeout or bindings complete).

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.
