 Optional Requirements
 ---------------------
 
-When virglrenderer is built with ``-Dminigbm_allocation=true``, the Venus
-renderer might need to import GBM BOs.  The imports will fail unless the host
-driver supports the formats, especially multi-planar ones, and the DRM format
-modifiers of the GBM BOs.
-
 In the future, if virglrenderer's ``virgl_renderer_export_fence`` is
 supported, the Venus renderer will require :ext:`VK_KHR_external_fence_fd`
 with ``VK_EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT`` from the host driver.
