There are few scenerio when PMC reports 'busy condition' and command fail. If PMC receives a high priority command while servicing a low priority command then it discards the low priority command and start servicing the high priority command. The lower priority command fail and driver returns error. If the same command resend to the PMC then PMC latches the command and service it accordingly. Thus adds the retry logic for the PMC command.

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.
