Linux kernel source tree
Moving the init_clock_gating() call from intel_modeset_init_hw() to intel_modeset_gem_init() had an unintended effect of not applying some workarounds on resume. This, for example, cause some kind of corruption to appear at the top of my IVB Thinkpad X1 Carbon LVDS screen after hibernation. Fix the problem by explicitly calling init_clock_gating() from the resume path. I really hope this doesn't break something else again. At least the problems reported at https://bugs.freedesktop.org/show_bug.cgi?id=103549 didn't make a comeback, even after a hibernate cycle. v2: Reorder the init_clock_gating vs. modeset_init_hw to match the display reset path (Rodrigo) Cc: stable@vger.kernel.org Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Fixes: |

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.
