[PATCH v5 00/12] Enable GPU switching on pre-retina MacBook Pro

Enable GPU switching on the pre-retina MacBook Pro (2008 - 2013), v5. The main obstacle on these machines is that the panel mode in VBIOS is bogus. Fortunately gmux can switch DDC independently from the display, thereby allowing the inactive GPU to probe the panel's EDID. In short, vga_switcheroo

Hello all, This patch series is a continuation of rework of blending support in Exynos DRM driver. Some background can be found here: http://www.spinics.net/lists/dri-devel/msg96969.html Daniel Vetter suggested that zpos property should be made generic, with well-defined semantics. This patchset

In addition to the last-in/first-out stack for accessing drm_mm nodes, we occasionally and in the future often want to find a drm_mm_node by an address. To do so efficiently we need to track the nodes in an interval tree - lookups for a particular address will then be O(lg(N)), where N is the numbe

When userspace closes a handle, we remove it from the file->object_idr and then tell the driver to drop its references to that file/handle. However, as the file/handle is already available again for reuse, it may be reallocated back to userspace and active on a new object before the driver has had
