[Why] The MPCC may change and request data when the pipes are switching from 2 to 1 or 1 to 2. During the switch there is a possibility of underflow and flicker/missing data. [How] During VBlank the MPCC won't request data. The trick is to delay and wait on VBlank, ONLY when pipes are either turning on or off, right before MPCC is reset for the pipes.

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.
