For some reason lost in history function vchiq_mmal_init used a static variable for storing the vchiq_instance. This value is retrieved from vchiq per instance, so worked fine until you try to call vchiq_mmal_init multiple times concurrently when things then go wrong. This seemed to happen quite frequently if using the cutdown firmware (no MMAL or VCSM services running) as the vchiq_connect then failed, and one or other vchiq_shutdown was working on an invalid handle. Remove the static so that each caller gets a unique vchiq_instance. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
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.
