under virtualization enviroment, it is possible guest update pipe registers across vblank intervals due to overhead of mmio traps or vm schedule out. However, it is safe since those pipe update happen in virual registers and will not be committed to hardware. suppress that atomic commit error message under virtualization case to avoid confusing user. v2: per ville's comment: return early and against Maarten's patch v3: coding style clean Signed-off-by: Bing Niu <bing.niu@intel.com> Acked-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1489004043-15449-1-git-send-email-bing.niu@intel.com Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com>
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.
