    drm/i915: Recognise non-VGA display devices · 934f992c
    Chris Wilson 提交于
    Starting with SandyBridge (though possible with earlier hacked BIOSes),
    the BIOS may initialise the IGFX as secondary to a discrete GPU. Prior,
    it would simply disable the integrated GPU. So we adjust our PCI class
    mask to match any DISPLAY_CLASS device.
    
    In such a configuration, the IGFX is not a primary VGA controller and
    so should not take part in VGA arbitration, and the error return from
    vga_client_register() is expected.
