    drm/i915/gvt: Deliver guest cursor hotspot info · 1c6ccad8
    Tina Zhang 提交于
    Guest OS driver uses PV info registers to deliver cursor hotspot info
    to host. This patch is used to get cursor hotspot info from virtual
    registers and deliver it to host userspace.
    
    v4->v5:
    - remove CI warning.
    
    v3->v4:
    - return UINT_MAX when x_hot/y_hot is invalid. (Zhenyu)
    - correct version.
    
    v2->v3:
    - add validate_hotspot(). (Zhenyu)
    
    v1->v2:
    - name as cursor_x_hot/cursor_y_hot. (Zhenyu)
    - use i915_reg_t definition instead of magic numbers. (Zhenyu)
