    drm: Add GEM ("graphics execution manager") to i915 driver. · 673a394b
    Eric Anholt authored
    GEM allows the creation of persistent buffer objects accessible by the
    graphics device through new ioctls for managing execution of commands on the
    device.  The userland API is almost entirely driver-specific to ensure that
    any driver building on this model can easily map the interface to individual
    driver requirements.
    
    GEM is used by the 2d driver for managing its internal state allocations and
    will be used for pixmap storage to reduce memory consumption and enable
    zero-copy GLX_EXT_texture_from_pixmap, and in the 3d driver is used to enable
    GL_EXT_framebuffer_object and GL_ARB_pixel_buffer_object.
