In order to prevent a race condition where we may end up overaccounting the active state and leaving the busy-stats believing the GPU is 100% busy, lock out the tasklet while we reconstruct the busy state. There is no direct spinlock guard for the execlists->port[], so we need to utilise tasklet_disable() as a synchronous barrier to prevent it, the only writer to execlists->port[], from running at the same time as the enable.

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.
