Resetting the VBIF before power collapse is done to avoid getting bogus FIFO entries during the suspend sequence or subsequent resume, but this is doable only on Adreno 510 and Adreno 530, as the other units will tendentially lock up. Especially on Adreno 508, the GPU will show lockups and very bad slownesses after processing the first frame. Avoiding to execute the RBBM SW Reset before suspend will stop the lockup issue from happening on at least Adreno 508/509/512.

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.
