    drm/i915/gvt: Fix drm_format_mod value for vGPU plane · b244ffa1
    Zhenyu Wang authored
    Physical plane's tiling mode value is given directly as
    drm_format_mod for plane query, which is not correct fourcc
    code. Fix it by using correct intel tiling fourcc mod definition.
    
    Current qemu seems also doesn't correctly utilize drm_format_mod
    for plane object setting. Anyway this is required to fix the usage.
    
    v3: use DRM_FORMAT_MOD_LINEAR, fix comment
    
    v2: Fix missed old 'tiled' use for stride calculation
