    drm/vmwgfx: Support topology greater than texture size · 810b3e16
    Sinclair Yeh authored
    Most of the display servers today use a single surface to represent the
    entire desktop even if it's stretched across multiple screens.
    
    For vmwgfx with STDU, the maximum surface size is limited to the
    maximum texture size on the host.  On a 2D VM, this limits our
    ability to support configurations with more than one 4K monitor.
    
    To get past this limitation, we will now allow using a large DMA buf
    as the framebuffer, and take care of blitting contents from this DMA buf
    to the display buffer.
