Commands written to the QMan software portals have a valid bit in the "verb" field of the command that, when set with the right value, notifies the hardware that the command is fully written and ready to be processed. The "verb" field should be the last one to be written in the swp command registers, after all other fields are filled in. The current implementation doesn't follow this rule for all commands, which may result in an incompletely configured command being processed by the hardware. Enforce the correct order of writes to avoid this situation. Signed-off-by: Ioana Radulescu <ruxandra.radulescu@nxp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
