    Support CRTC variable refresh for windows using Present flips · b11ee02c
    Nicholas Kazlauskas authored
    This patch adds support for setting the CRTC variable refresh property
    for suitable windows flipping via the Present extension.
    
    The "VariableRefresh" Option is added to AMDGPU in this patch. This
    option defaults to false, and must be set to "true" in an X conf
    file for variable refresh support in the driver.
    
    In order for a window to be suitable for variable refresh it must have
    the _VARIABLE_REFRESH property with a 32-bit CARDINAL value of 1.
    
    Then the window must pass the checks required to be suitable for
    Present extension flips - it must cover the entire X screen and no
    other window may already be flipping.
    
    With these conditions met every CRTC for the X screen will have their
    variable refresh property set to true.
