    drm/i915: Add the predicate source registers to the register whitelist · f1f55cc0
    Neil Roberts 提交于
    The predicate source registers are needed to implement conditional
    rendering without stalling. The two source registers are used to load
    the previous values of the PS_DEPTH_COUNT register saved from
    PIPE_CONTROL commands. These can then be compared and used to set the
    predicate enable bit via the MI_PREDICATE command.
    
    The command parser version number is increased to 2 to make it easier
    to detect the new functionality in user space.
